  • The Earth keeps getting hotter, and Americans’ trust in science is on a down trend

    [ad_1]

    As global officials confirm that 2025 was Earth’s third-hottest year on record, a new poll shows Americans are sharply divided over the role of science in the United States.

    A report published Thursday by the nonpartisan Pew Research Center found that a majority of Americans want the U.S. to be a world leader in science, but Republicans and Democrats disagree on whether it is.

    About two-thirds of Democrats, 65%, fear the U.S. is losing ground to other countries when it comes to scientific achievement — a 28-point increase since 2023, the poll found. Republicans have moved in the opposite direction, with far fewer saying the U.S. is losing ground than in the past, 32%, a 12-point decrease in that same time frame.

    The divide mirrors “other partisan differences in attitudes around science we have been tracking for years,” the Pew report says. “In particular, partisan differences in trust in scientists and the value of science for society are far wider than they were before the COVID-19 pandemic. Republicans have become less confident in scientists and less likely to say science has had a mostly positive effect on society, while Democratic views are largely unchanged.”

    The report notes that the Trump administration has reshaped federal science policy, including eliminating research grants, cutting science and health workforces, and shifting priorities away from climate change research. Last month, the administration dismantled one of the world’s leading climate and weather research institutions, the National Center for Atmospheric Research in Boulder, Colo.

    About 90% of Democrats say they have at least a fair amount of confidence in scientists, but only 65% of Republicans said the same, according to the poll, which surveyed 5,111 U.S. adults in October. The gap in confidence between both parties on this point has been broadly similar in every survey since 2021.

    Experts said the findings are not particularly surprising.

    “It’s part of a larger trend toward the politicization of science,” said Zeke Hausfather, a climate scientist at Berkeley Earth, citing issues such as vaccines and climate change. He said concerns about “falling behind” may be warranted as “the U.S. is very much doubling down on being a ‘petro state’ — exporting our oil and gas — whereas other parts of the world, particularly China, are doubling down on exporting clean energy technologies like wind, solar and batteries.”

    The report lands as the world continues to head in the wrong direction when it comes to global warming.

    On Wednesday, eight international groups released data confirming that 2025 was Earth’s third-hottest year on record — nearly tied with 2023 and just behind 2024, the warmest year on record. The groups include the National Oceanic and Atmospheric Administration, NASA, the European Union’s Copernicus Climate Change Service, the Japan Meteorological Agency and the Chinese Ministry of Science and Technology.

    The past 11 years have been the 11 warmest on record, according to Copernicus.

    Last year’s global average temperature was about 2.65 degrees above pre-industrial levels, the baseline against which global warming is measured. That means it was just shy of the 2.7 degree limit (1.5 degrees Celsius) established under the 2015 Paris climate agreement, an internationally recognized tipping point for the worst effects of climate change.

    “The news is not encouraging, and the urgency of climate action has never been more important,” Mauro Facchini, head of Earth observation at the European Commission’s Directorate General for Defense Industry and Space, told reporters this week.

    Yet Trump withdrew the U.S. from the Paris agreement on his first day back in office, a move he also made during his first term as president. This month, he also withdrew the U.S. from 66 other international organizations and treaties, including the United Nations Framework Convention on Climate Change, from which the Paris agreement stems.

    The world is now on track to breach the Paris agreement’s limit for long-term global warming before the end of the decade — several years earlier than predicted, according to Hausfather, who also helped produce Berkeley Earth’s global temperature report that was released this week. He said it is likely that 2026 will fall “somewhere between the second and fourth warmest” years on record.

    “The new data is the latest unequivocal evidence that our climate is in crisis,” said Carlos Martinez, a senior climate scientist with the Union of Concerned Scientists. But “the Trump administration is not simply refusing to face the reality of climate change we are experiencing, it is actively lying about science and undermining our nation’s federal scientific resources.”

    Last year wasn’t only warm globally. The contiguous U.S. experienced the fourth-warmest year in its 131-year record, according to NOAA’s assessment. Utah and Nevada recorded their warmest years on record at 4.3 degrees and 3.7 degrees above their 20th century averages, respectively. California tied for its fourth-warmest year on record.

    NOAA previously tracked weather and climate disasters where damages exceed $1 billion, but the Trump administration shut down that database last year. The administration also fired hundreds of scientists working to prepare the congressionally mandated National Climate Assessment and removed the website that housed previous assessments.

    Officials with multiple international groups this week stressed that global cooperation is key as warmer temperatures worldwide worsen the frequency and intensity of extreme weather events such as heat waves, wildfires and floods.

    “Collaborative and scientifically rigorous global data collection is more important than ever before because we need to ensure that Earth information is authoritative, accessible and actionable for all,” said Celeste Saulo, secretary-general of the World Meteorological Organization.

    “Data and observations are essential to our efforts to confront climate change and air quality challenges, and these challenges don’t know borders,” said Florian Pappenberger, director-general of the European Center for Medium-Range Weather Forecasts. However, he noted that NOAA Administrator Neil Jacobs has committed to not deleting any data, “which is a welcome thing.”

    “Data don’t lie,” Pappenberger said. “All we need to do is measure them.”

  • Trump administration moves to dismantle leading climate and weather research center

    [ad_1]

    The Trump administration is moving to dismantle one of the world’s leading climate and weather research institutions, the National Center for Atmospheric Research in Boulder, Colo., in a decision experts say will undermine U.S. scientific competitiveness and leave millions vulnerable to worsening climate hazards.

    Russell Vought, director of the White House’s Office of Management and Budget, made the surprise announcement in a Tuesday evening post on X.

    “This facility is one of the largest sources of climate alarmism in the country,” Vought wrote. “A comprehensive review is underway & any vital activities such as weather research will be moved to another entity or location.”

    The news sent shock waves through the scientific community. The center’s work is used by governments, universities, emergency planners and the private sector for forecasts and disaster response planning. Its sophisticated Community Earth System Model underpins international climate assessments and much of U.S. policy. The federally funded research center employs about 830 staff members, making it one of the largest consortia of scientists who study weather, climate and Earth systems using advanced models and supercomputers in the world.

    “The Trump administration has put a bull’s-eye on one of the United States’ premier weather and climate research and modeling centers, threatening to destroy decades of public investment,” said Carlos Martinez, a former researcher at the center, now a senior climate scientist at the Union of Concerned Scientists. “Deliberately dismantling an institution so central to weather forecasting and climate change prediction would not only undermine scientific research, it would leave people across the nation less prepared for the dangers of a warming world.”

    A senior White House official confirmed the plan to The Times, saying the National Science Foundation, which funds the center, will be breaking up the facility to “eliminate Green New Scam research activities.” As the largest federal research program on climate change, the center serves as the “premier research stronghold for left-wing climate lunacy,” the official said.

    Officials with the National Science Foundation on Wednesday said the agency is “reviewing the structure of the research and observational capabilities” at the center, and is exploring options to transfer stewardship of its Wyoming Supercomputing Center to “an appropriate operator.” The agency also is looking to divest two aircraft managed by the center and to “redefine the scope” of modeling and forecasting research and operations.

    “NSF remains committed to providing world-class infrastructure for weather modeling, space weather research and forecasting and other critical functions,” the agency said. “To do so, NSF will be engaging with partner agencies, the research community, and other interested parties to solicit feedback for rescoping the functions of the work currently performed by NCAR.”

    Although the White House official characterized the center’s work as “climate lunacy,” changes in the climate are coming faster than many scientists predicted. The basic science of climate change has been well-established through decades of research.

    Daniel Swain, a climate scientist at the University of California Agriculture and Natural Resources, said it is hard to overstate the importance of the center. “There is no other institution like NCAR — not just in this country but really anywhere else in the world,” Swain said during a briefing Wednesday morning. He feared that no other global institution can absorb the entirety of its expertise.

    Swain also described the administration’s decision as “nakedly politically partisan” in a manner that does not align with public interest. The center’s predictions “aren’t just helpful or convenient — they are life-saving and economy-saving,” he said, adding that shuttering the facility would be “an unbelievable, really genuinely shocking self-inflicted wound to American competitiveness.”

    Indeed, the loss of the facility would leave millions of people vulnerable to worsening climate hazards such as wildfires, hurricanes, tropical cyclones and winter storms, Swain and other experts said. Its Wyoming Supercomputing Center provides massive computational resources to national and international scientists for running complex weather and climate models and simulations.

    In California, many universities and state agencies use data and modeling from the center for air pollution monitoring, managing water, emergency planning and wildfire risk assessment, among many other uses.

    Data and tools from the center also are used directly and indirectly by the private sector.

    For instance, the center provides large amounts of atmospheric data, via the Climate Data Guide and Community Earth System Model Large Ensemble Numerical Simulation, that researchers, insurance companies and even AI data scientists can access and use to train models, gauge risk and make forecasts.

    The aviation, energy and private weather forecasting industries all rely on data and tools developed by the center, including a technology product known as BoltAlert, which is used to predict lightning strikes, and the Maintenance Decision Support System, which alerts snowplow and truck fleets about road conditions.

    The $700-billion reinsurance industry also relies on the center’s data, tools and climate models to create financial instruments, such as catastrophe bonds, that are directly tied to weather or natural disaster risks. Such vehicles are dependent upon thorough and precise past data, as well as climate models for forecasting potential risk.

    For instance, the reinsurance giant SwissRe credits the work of the center in the development of its proprietary forecasting tool known as the CatNet. In a press statement about the product, the company said its catastrophe experts partnered with the center to create globally validated hail predictions.

    Franklin Nutter, spokesman and former president of the Reinsurance Assn. of America — a reinsurance trade group — said his understanding is that NCAR will be broken up and directed to focus on “weather.”

    “It is unclear what this means for climate research,” Nutter said in an email. “NCAR has been the world’s leading research hub” in part because of its super computing capabilities, which allow it to analyze weather over time, i.e. the climate.

    He said a recent study of 40 years of Midwest hail patterns show that patterns have changed — in frequency, severity and geography. The insurance sector and local and state governments use this information to assess changing risk patterns. He said the center also has “studied the dynamics of wildfires to understand development patterns and intensity.”

    The center also provides real time weather data which the insurance, reinsurance and investment sector uses to determine whether a catastrophe bond gets paid out.

    “Perhaps most importantly, NCAR is needed to bring together the critical resources [super computing and talent] to provide research and weather-related innovation that provides federal, state and local governments with insights about preparedness and response,” he said, noting that the center’s funding comes from not just the National Science Foundation but also the Department of Defense, the Department of Energy and the Federal Aviation Administration.

    “Maintaining the U.S. leadership role, developing talent in the natural sciences and innovation has been a hallmark of NCAR,” he said. His trade group “believes it should be maintained and additional resources provided to it.”

    The decision to close the facility follows other efforts from the Trump administration to shut down scientific research and change the public view of climate change. That includes laying off hundreds of staffers at the National Oceanic and Atmospheric administration and slashing funding for its scientific research arm. The Trump administration also fired hundreds of scientists working to prepare the congressionally mandated National Climate Assessment and removed the website that housed previous assessments.

    The announcement came as a surprise to Colorado Gov. Jared Polis, who said in a statement shortly after Vought’s announcement that the state had “yet to receive information” about the plan.

    “If true, public safety is at risk and science is being attacked,” Polis said. “Climate change is real, but the work of NCAR goes far beyond climate science. NCAR delivers data around severe weather events like fires and floods that help our country save lives and property, and prevent devastation for families. If these cuts move forward, we will lose our competitive advantage against foreign powers and adversaries in the pursuit of scientific discovery.”

    When asked why the administration is closing the facility, White House officials pointed to so-called “woke” programs at the center that they said “waste taxpayer funds” and “veer from strong or useful science,” such as its Rising Voices Center aimed at joining Indigenous knowledge and Earth science, and an art series that explored the human relationship with water.

    They also cited the center’s research into wind turbines that sought to better understand the impact of weather conditions on offshore wind production. Trump has been vocal about his opposition to offshore wind and other forms of renewable energy.

  • A new virus variant and lagging vaccinations may mean the US is in for a severe flu season

    [ad_1]

    The United States may be heading into its second severe flu season in a row, driven by a mutated strain called subclade K that’s behind early surges in the United Kingdom, Canada and Japan.Last winter’s season was extreme, too. The U.S. had its highest rates of flu hospitalizations in nearly 15 years. At least 280 children died of influenza, the highest number since pediatric death numbers were required to be shared in 2004.Now, with a new variant in the mix, experts say we’re on track for a repeat. And with flu vaccinations down and holiday travel on the way, they worry that things may look much worse in the weeks ahead.The good news: Early analysis shows that this season’s flu shots offer some protection against being hospitalized with this variant, especially for kids. The bad news is that many Americans appear to be skipping their flu vaccines this year. New data from prescription data company IQVIA shows that vaccinations are down compared to where they usually are at this point in the year.A new playerFlu activity is low but rising quickly in the United States, according to the latest FluView report from the U.S. Centers for Disease Control and Prevention.Most of the flu viruses identified this season have been an A strain called H3N2, and half of those have come from subclade K, a variant that was responsible for a rougher-than-normal flu season this summer in the Southern Hemisphere.That variant wasn’t a major player when scientists decided which strains should be in the annual flu shots, so the vaccines cover a related but slightly different group of viruses.”It’s not like we’re expecting to get complete loss of protection for the vaccine, but perhaps we might expect a little bit of a drop-off if this is the virus that sort of dominates the season, and early indications are that’s probably going to be the case,” said Dr. Richard Webby, director of the World Health Organization Collaborating Center for studies on the ecology of influenza in animals and birds at St. Jude Children’s Research Hospital.Early analysis by the U.K. Health Security Agency shows that subclade K has seven gene changes on a key segment of the virus. Those mutations change the shape of this region, making it harder for the body’s defenses to recognize.”That’s the predominant thing that our immune system targets with antibodies, and that’s also pretty much what’s in the vaccine,” said Dr. Adam Lauring, chief of the Division of Infectious Diseases at the University of Michigan Medical School.UKHSA scientists found that the current flu vaccines are still providing decent protection against subclade K viruses. Vaccination cut the odds of an emergency department visit or hospitalization for the flu by almost 75% in children. The effectiveness for adults, even those over 65, was lower, about 30% to 40% against needing to visit the hospital or ER.But the scientists offer a caveat: These results are from early in the season, before the protection from seasonal flu vaccines has had time to wane or wear off. The findings are posted in a recent preprint study, which means it was published ahead of scrutiny from outside experts.Still, some protection is better than no protection, and while subclade K is expected to dominate the season, it won’t be the only flu strain circulating. No one gets to pick what they’re exposed to. Lauring said his daughter has just recovered from the flu, but it was a B-type strain.At the same time this new variant has emerged, flu vaccinations appear to be down in the U.S. According to IQVIA, about 64% of all flu vaccinations were administered at retail pharmacies, which administered roughly 26.5 million flu shots between August and the end of October. That’s more than 2 million fewer shots than the 28.7 million given over the same time frame in 2024.”I’m not surprised,” said Dr. Jennifer Nuzzo, who directs the Pandemic Center at Brown University’s School of Public Health. Vaccine skepticism expressed by leaders of the US Department of Health and Human Services has “injected chaos into the whole vaccination system,” she said.”There’s been a lot of attention on really non-issues,” like vaccine ingredients and separating shots, that she thinks “at the best, left people confused but possibly at the worst have left people worried about getting vaccinated,” she added.Flu vaccinations have also fallen in Australia, where subclade K was the predominant virus this year. As a result, flu hit a record, with more than 443,000 cases. Flu season in the Southern Hemisphere typically runs from May to July, so infectious disease experts often look to those countries for a preview of what might be on the way to North America.”What they saw in Australia is that they had a bad season. And so it’s concerning for you and us, what’s coming,” said Dr. Earl Rubin, director of the infectious disease division at the Montreal Children’s Hospital in Canada.’This is the time we start to see the rise’It’s difficult to say whether subclade K actually makes a person sicker than other flu strains, but if it drives more cases, it will certainly drive hospitalizations too, Rubin said.”When you look at severity, the more cases you have, if the same percentage get hospitalized, obviously you’re going to have more hospitalization if you have more cases. So it sometimes will look like the severity is also worse,” he said.Lab testing data has begun to show an uptick in flu cases.”This is the time we start to see the rise,” said Dr. Allison McMullen, a clinical microbiologist at BioMerieux, which makes the BioFire test, a popular diagnostic tool for respiratory pathogens.The company anonymously compiles its test results into a syndromic surveillance tool, which can offer a glimpse of what bugs are making people sick at any given time. At the beginning of the month, less than 1% of tests were positive for type A flu. Now it’s 2.4% – still low numbers but going up briskly, which aligns with the CDC trend.”We’re going to start seeing heavy holiday travel before we know it,” McMullen added. “With the rising cases that we’re seeing the U.K. and Japan, it can definitely be a bellwether for what we’re going to see in North America.”Signals are also rising in wastewater, said Dr. Marlene Wolfe, an assistant professor of environmental health at Emory University. In October, 18% of samples in the WastewaterSCAN network — an academically led wastewater monitoring program based at Stanford University, in partnership with Emory — were positive for type A flu, Wolfe said. In November, that number had risen to 40%.”Flu is something where, when it’s not in season, we don’t detect it very frequently in wastewater,” Wolfe said. COVID, on the other hand, can be detected pretty much all the time, which makes it challenging to know if it’s going up or down, she said.The scientists can set a threshold for when they can declare that a specific area is in flu season, Wolfe says. So far, just four of the 147 sites they monitor in 40 states have reached that threshold. Those sites are in the Northeast — in Maine and Vermont — in Iowa and in Hawaii.”I am concerned, I guess, that we could have a big flu season this year based on what we’re seeing in other parts of the world, and particularly Europe and elsewhere,” Michigan’s Lauring said.”It’s not too late. Go and get your flu shot,” Lauring advised. “And be alert that it’s out there.”

  • Humanity is on path toward ‘climate chaos,’ scientists warn

    [ad_1]

    Industries and individuals around the world burned record amounts of oil, gas and coal last year, releasing more greenhouse gases than ever before, a group of leading scientists said in a new report, warning that humanity is hurtling toward “climate chaos.”

    The surge in global use of fossil fuels in 2024 contributed to extreme weather and devastating disasters including heat waves, storms, floods and wildfires.

    “The planet’s vital signs are flashing red,” the scientists wrote in their annual report on the state of the climate. “The window to prevent the worst outcomes is rapidly closing.”

    Some of the most alarming of Earth’s “vital signs,” the researchers said, include record heat in the oceans ravaging coral reefs, rapidly shrinking ice sheets and increasing losses of forests burned in fires around the world. They said the extreme intensity of Hurricane Melissa this week is another sign of how the altered climate is threatening lives and communities on an unprecedented scale.

    “The climate crisis has reached a really dangerous stage,” said William Ripple, the report’s co-lead author and a professor at Oregon State University. “It is vital that we limit future warming as rapidly as possible.”

    There is still time to limit the damage, Ripple said. It means switching to cleanly made electricity, clean transportation, fewer beef and dairy cows and other sources of harmful gases. These transitions are happening in some places, though not nearly fast enough.

    For example, fossil fuel use actually fell in China in the first half of this year, a remarkable change for a country that remains the world’s biggest climate polluter. Renewable energy is being built out at a furious pace there, dwarfing installation in rest of the world. And in California, clean energy provided two-thirds of electricity in 2023.

    Yet total use of fossil fuels rose 1.5% in 2024, the researchers said, citing data from the Energy Institute. Energy-related emissions of carbon dioxide and other planet-heating gases also reached an all-time high — exactly the opposite of what needs to be happening to address climate change.

    The report notes that hotter temperatures are contributing to growing electricity demand.

    “Avoiding every fraction of a degree of warming is critically important,” the scientists wrote. “We are entering a period where only bold, coordinated action can prevent catastrophic outcomes.”

    The report, published Wednesday in the journal BioScience, is the sixth annual assessment that Ripple and his colleagues have compiled since they wrote a 2020 paper declaring a climate emergency — a statement that more than 15,800 scientists have signed in support.

    The scientists said the current pace of warming greatly increases the risks of crossing dangerous climate tipping points, including vicious cycles such as the collapse of ice sheets, thawing of carbon-rich permafrost and widespread dieback of forests.

    Ripple and his colleagues stressed that adopting solutions now to reduce emissions can swiftly bring benefits and that these solutions will be far less expensive than dealing with the consequences of uncontrolled climate change.

    Efforts by President Trump and his administration to boost production of oil, gas and coal seriously threaten to slow the shift toward clean energy, said Michael Mann, a climate scientist and professor at the University of Pennsylvania.

    He and co-author Peter Hotez argue in the recent book “Science Under Siege” that other nations must take on greater leadership now that the U.S. and other oil-promoting governments are working to block action on climate change.

    Other scientists who helped write the report said the Trump administration is turning a blind eye to threats including sea-level rise, worsening droughts and wildfires, and diminished agricultural output.

    “It’s a scandal that the U.S. is pulling back from any efforts to address environmental challenges,” said Peter Gleick, co-founder and senior fellow of the Pacific Institute, a think tank in Oakland. “The rest of the world should ignore efforts by the U.S. to delay progress on these problems … and I’m hopeful that other countries will continue to step up.”

    The upcoming United Nations climate conference in Brazil in November could be a turning point if countries commit to bold and transformative changes, Ripple said.

    Solutions must involve not only phasing out fossil fuels, the scientists said, but also addressing the fact that people are using up resources faster than nature can replenish them. Researchers, they noted, have estimated that two-thirds of the warming since 1990 is attributable to the wealthiest 10% of the world’s people because of “high-consumption lifestyles, high per capita fossil fuel use, and investments.”

    The scientists called for changes including “reducing overconsumption” among the wealthy, protecting and restoring ecosystems, and shifting away from meat-heavy diets to more plant-based foods.

    “It’s not just about cutting emissions. Dealing with climate change requires more,” Ripple said. “It calls for deep, systemic change in how societies value nature, design economies, consume resources and define progress.”

    Jane Goodall, the trailblazing naturalist whose intimate observations of chimpanzees in the African wild produced powerful insights that transformed basic conceptions of humankind, has died. She was 91.

    A tireless advocate of preserving chimpanzees’ natural habitat, Goodall died on Wednesday morning in California of natural causes, the Jane Goodall Institute announced on its Instagram page.

    “Dr. Goodall’s discoveries as an ethologist revolutionized science,” the Jane Goodall Institute said in a statement.

    A protege of anthropologist Louis S.B. Leakey, Goodall made history in 1960 when she discovered that chimpanzees, humankind’s closest living ancestors, made and used tools, characteristics that scientists had long thought were exclusive to humans.

    She also found that chimps hunted prey, ate meat, and were capable of a range of emotions and behaviors similar to those of humans, including filial love, grief and violence bordering on warfare.

    In the course of establishing one of the world’s longest-running studies of wild animal behavior at what is now Tanzania’s Gombe Stream National Park, she gave her chimp subjects names instead of numbers, a practice that raised eyebrows in the male-dominated field of primate studies in the 1960s. But within a decade, the trim British scientist with the tidy ponytail was a National Geographic heroine, whose books and films educated a worldwide audience with stories of the apes she called David Graybeard, Mr. McGregor, Gilka and Flo.

    “When we read about a woman who gives funny names to chimpanzees and then follows them into the bush, meticulously recording their every grunt and groom, we are reluctant to admit such activity into the big leagues,” the late biologist Stephen Jay Gould wrote of the scientific world’s initial reaction to Goodall.

    But Goodall overcame her critics and produced work that Gould later characterized as “one of the Western world’s great scientific achievements.”

    Tenacious and keenly observant, Goodall paved the way for other women in primatology, including the late gorilla researcher Dian Fossey and orangutan expert Birutė Galdikas. She was honored in 1995 with the National Geographic Society’s Hubbard Medal, which then had been bestowed only 31 times in the previous 90 years to such eminent figures as North Pole explorer Robert E. Peary and aviator Charles Lindbergh.

    In her 80s she continued to travel 300 days a year to speak to schoolchildren and others about the need to fight deforestation, preserve chimpanzees’ natural habitat and promote sustainable development in Africa. She was in California as part of her speaking tour in the U.S. at the time of her death.

    Goodall was born April 3, 1934, in London and grew up in the English coastal town of Bournemouth. The daughter of a businessman and a writer who separated when she was a child and later divorced, she was raised in a matriarchal household that included her maternal grandmother, her mother, Vanne, some aunts and her sister, Judy.

    She demonstrated an affinity for nature from a young age, filling her bedroom with worms and sea snails that she rushed back to their natural homes after her mother told her they would otherwise die.

    When she was about 5, she disappeared for hours to a dark henhouse to see how chickens laid eggs, so absorbed that she was oblivious to her family’s frantic search for her. She did not abandon her study until she observed the wondrous event.

    “Suddenly with a plop, the egg landed on the straw. With clucks of pleasure the hen shook her feathers, nudged the egg with her beak, and left,” Goodall wrote almost 60 years later. “It is quite extraordinary how clearly I remember that whole sequence of events.”

    When finally she ran out of the henhouse with the exciting news, her mother did not scold her but patiently listened to her daughter’s account of her first scientific observation.

    Later, she gave Goodall books about animals and adventure — especially the Doctor Dolittle tales and Tarzan. Her daughter became so enchanted with Tarzan’s world that she insisted on doing her homework in a tree.

    “I was madly in love with the Lord of the Jungle, terribly jealous of his Jane,” Goodall wrote in her 1999 memoir, “Reason for Hope: A Spiritual Journey.” “It was daydreaming about life in the forest with Tarzan that led to my determination to go to Africa, to live with animals and write books about them.”

    Her opportunity came after she finished high school. A week before Christmas in 1956 she was invited to visit an old school chum’s family farm in Kenya. Goodall saved her earnings from a waitress job until she had enough for a round-trip ticket.

    She arrived in Kenya in 1957, thrilled to be living in the Africa she had “always felt stirring in my blood.” At a dinner party in Nairobi shortly after her arrival, someone told her that if she was interested in animals, she should meet Leakey, already famous for his discoveries in East Africa of man’s fossil ancestors.

    She went to see him at what’s now the National Museum of Kenya, where he was curator. He hired her as a secretary and soon had her helping him and his wife, Mary, dig for fossils at Olduvai Gorge, a famous site in the Serengeti Plains in what is now northern Tanzania.

    Leakey spoke to her of his desire to learn more about all the great apes. He said he had heard of a community of chimpanzees on the rugged eastern shore of Lake Tanganyika where an intrepid researcher might make valuable discoveries.

    When Goodall told him this was exactly the kind of work she dreamed of doing, Leakey agreed to send her there.

    It took Leakey two years to find funding, which gave Goodall time to study primate behavior and anatomy in London. She finally landed in Gombe in the summer of 1960.

    On a rocky outcropping she called the Peak, Goodall made her first important observation. Scientists had thought chimps were docile vegetarians, but on this day about three months after her arrival, Goodall spied a group of the apes feasting on something pink. It turned out to be a baby bush pig.

    Two weeks later, she made an even more exciting discovery — the one that would establish her reputation. She had begun to recognize individual chimps, and on a rainy October day in 1960, she spotted the one with white hair on his chin. He was sitting beside a mound of red earth, carefully pushing a blade of grass into a hole, then withdrawing it and poking it into his mouth.

    When he finally ambled off, Goodall hurried over for a closer look. She picked up the abandoned grass stalk, stuck it into the same hole and pulled it out to find it covered with termites. The chimp she later named David Graybeard had been using the stalk to fish for the bugs.

    “It was hard for me to believe what I had seen,” Goodall later wrote. “It had long been thought that we were the only creatures on earth that used and made tools. ‘Man the Toolmaker’ is how we were defined …” What Goodall saw challenged man’s uniqueness.

    When she sent her report to Leakey, he responded: “We must now redefine man, redefine tool, or accept chimpanzees as human!”

    Goodall’s startling finding, published in Nature in 1964, enabled Leakey to line up funding to extend her stay at Gombe. It also eased Goodall’s admission to Cambridge University to study ethology. In 1965, she became the eighth person in Cambridge history to earn a doctorate without first having a bachelor’s degree.

    In the meantime, she had met and in 1964 married Hugo Van Lawick, a gifted filmmaker who had traveled to Gombe to make a documentary about her chimp project. They had a child, Hugo Eric Louis — later nicknamed Grub — in 1967.

    Goodall later said that raising Grub, who lived at Gombe until he was 9, gave her insights into the behavior of chimp mothers. Conversely, she had “no doubt that my observation of the chimpanzees helped me to be a better mother.”

    She and Van Lawick were married for 10 years, divorcing in 1974. The following year she married Derek Bryceson, director of Tanzania National Parks. He died of colon cancer four years later.

    Within a year of arriving at Gombe, Goodall had chimps literally eating out of her hands. Toward the end of her second year there, David Graybeard, who had shown the least fear of her, was the first to allow her physical contact. She touched him lightly and he permitted her to groom him for a full minute before gently pushing her hand away. For an adult male chimpanzee who had grown up in the wild to tolerate physical contact with a human was, she wrote in her 1971 book “In the Shadow of Man,” “a Christmas gift to treasure.”

    Her studies yielded a trove of other observations on behaviors, including etiquette (such as soliciting a pat on the rump to indicate submission) and the sex lives of chimps. She collected some of the most fascinating information on the latter by watching Flo, an older female with a bulbous nose and an amazing retinue of suitors who was bearing children well into her 40s.

    Her reports initially caused much skepticism in the scientific community. “I was not taken very seriously by many of the scientists. I was known as a [National] Geographic cover girl,” she recalled in a CBS interview in 2012.

    Her unorthodox personalizing of the chimps was particularly controversial. The editor of one of her first published papers insisted on crossing out all references to the creatures as “he” or “she” in favor of “it.” Goodall eventually prevailed.

    Her most disturbing studies came in the mid-1970s, when she and her team of field workers began to record a series of savage attacks.

    The incidents grew into what Goodall called the four-year war, a period of brutality carried out by a band of male chimpanzees from a region known as the Kasakela Valley. The marauders beat and slashed to death all the males in a neighboring colony and subjugated the breeding females, essentially annihilating an entire community.

    It was the first time a scientist had witnessed organized aggression by one group of non-human primates against another. Goodall said this “nightmare time” forever changed her view of ape nature.

    “During the first 10 years of the study I had believed … that the Gombe chimpanzees were, for the most part, rather nicer than human beings,” she wrote in “Reason for Hope: A Spiritual Journey,” a 1999 book co-authored with Phillip Berman. “Then suddenly we found that the chimpanzees could be brutal — that they, like us, had a dark side to their nature.”

    Critics tried to dismiss the evidence as merely anecdotal. Others thought she was wrong to publicize the violence, fearing that irresponsible scientists would use the information to “prove” that the tendency to war is innate in humans, a legacy from their ape ancestors. Goodall persisted in talking about the attacks, maintaining that her purpose was not to support or debunk theories about human aggression but to “understand a little better” the nature of chimpanzee aggression.

    “My question was: How far along our human path, which has led to hatred and evil and full-scale war, have chimpanzees traveled?”

    Her observations of chimp violence marked a turning point for primate researchers, who had considered it taboo to talk about chimpanzee behavior in human terms. But by the 1980s, much chimp behavior was being interpreted in ways that would have been labeled anthropomorphism — ascribing human traits to non-human entities — decades earlier. Goodall, in removing the barriers, raised primatology to new heights, opening the way for research on subjects ranging from political coalitions among baboons to the use of deception by an array of primates.

    Her concern about protecting chimpanzees in the wild and in captivity led her in 1977 to found the Jane Goodall Institute to advocate for great apes and support research and public education. She also established Roots and Shoots, a program aimed at youths in 130 countries, and TACARE, which involves African villagers in sustainable development.

    She became an international ambassador for chimps and conservation in 1986 when she saw a film about the mistreatment of laboratory chimps. The secretly taped footage “was like looking into the Holocaust,” she told interviewer Cathleen Rountree in 1998. From that moment, she became a globe-trotting crusader for animal rights.

    In the 2017 documentary “Jane,” the producer pored through 140 hours of footage of Goodall that had been hidden away in the National Geographic archives. The film won a Los Angeles Film Critics Assn. Award, one of many honors it received.

    In a ranging 2009 interview with Times columnist Patt Morrison, Goodall mused on topics from traditional zoos — she said most captive environments should be abolished — to climate change, a battle she feared humankind was quickly losing, if not lost already. She also spoke about the power of what one human can accomplish.

    “I always say, ‘If you would spend just a little bit of time learning about the consequences of the choices you make each day’ — what you buy, what you eat, what you wear, how you interact with people and animals — and start consciously making choices, that would be beneficial rather than harmful.”

    As the years passed, Goodall continued to track Gombe’s chimps, accumulating enough information to draw the arcs of their lives — from birth through sometimes troubled adolescence, maturity, illness and finally death.

    She wrote movingly about how she followed Mr. McGregor, an older, somewhat curmudgeonly chimp, through his agonizing death from polio, and how the orphan Gilka survived to lonely adulthood only to have her babies snatched from her by a pair of cannibalistic female chimps.

    Her reaction in 1972 to the death of Flo, a prolific female known as Gombe’s most devoted mother, suggested the depth of feeling that Goodall had for the animals. Knowing that Flo’s faithful son Flint was nearby and grieving, Goodall watched over the body all night to keep marauding bush pigs from violating her remains.

    “People say to me, thank you for giving them characters and personalities,” Goodall once told CBS’s “60 Minutes.” “I said I didn’t give them anything. I merely translated them for people.”

  • Commentary: If he ever gets his job back, I have just the hat for Jimmy Kimmel, thanks to Trump

    [ad_1]

    These are dark times, the average cynic might argue.

    But do not despair.

    If you focus on the positive, rather than the negative, you’ll have to agree that the United States of America is on top and still climbing.

    Yes, protesters gathered Thursday outside “Jimmy Kimmel Live” in Hollywood to denounce ABC’s suspension of the host and President Trump’s threat to revoke licenses from networks that criticize him, despite repeated vows by Trump and top deputies to defend free speech.

    You can call it hypocrisy.

    I call it moxie.

    And by the way, demonstrators were not arrested or deported, and the National Guard was not summoned (as far as I know).

    Do you see what I mean? Just tilt your head back a bit, and you can see sunshine breaking through the clouds.

    Let’s take the president’s complaint that he read “someplace” that the networks “were 97% against me.” Some might see weakness in that, or thin skin. Others might wonder where the “someplace” was that the president discovered his TV news favorability rating stands at 3%, given that he could get caught drowning puppies and cheating at golf and still get fawning coverage from at least one major network.

    But Trump had good reason to be grumpy. He was returning from a news conference in London, where he confused Albania and Armenia and fumbled the pronunciation of Azerbaijan, which sounded a bit more like Abracadabra.

    It’s not his fault all those countries all start with an A. And isn’t there a geography lesson in it for all of us, if not a history lesson?

    We move on now to American healthcare, and the many promising developments under way in the nation’s capital, thanks to Trump’s inspired choice of Robert F. Kennedy Jr. as chief of the Department of Health and Human Services.

    Those who see the glass half empty would argue that Kennedy has turned the department into a morgue, attempting to kill COVID-19 vaccine research, espousing backwater views about measles, firing public health experts, demoralizing the remaining staff and rejecting decades worth of biomedical advances despite having no medical training or expertise.

    But on the plus side, Kennedy is going after food dyes.

    It’s about time, and thank you very much.

    I’m not sure what else will be left in a box of Trix or Lucky Charms when food coloring is removed, but I am opposed to fake food coloring, unless it’s in a cocktail, and I’d like to think most Americans are with me on this.

    Also on the bright side: Kennedy is encouraging Americans to do chin-ups and pushups for better health.

    Are you going to sit on the radical left side of your sofa and gripe about what’s happened to your country, or get with the program and try to do a few pushups?

    OK, so Trump’s efforts to shut down the war on cancer is a little scary. As the New York Times reported, on the chopping block is development of a new technique for colorectal cancer prevention, research into immunotherapy cancer prevention, a study on improving childhood cancer survival rates, and better analysis of pre-malignant breast tissue in high-risk women.

    But that could all be fake news, or 97% of it, at least. And if it’s not?

    All that research and all those doctors and scientists can apply for jobs in other countries, just like all the climate scientists whose work is no longer a national priority. The more who leave, the better, because the brain drain is going to free up a lot of real estate and help solve the housing crisis.

    Thank you, President Trump.

    Is it any wonder that Trump has been seen recently wearing a MAGA-red hat that says “TRUMP WAS RIGHT ABOUT EVERYTHING!”

    Well, mostly everything.

    Climate change appears to be real.

    The war in Ukraine didn’t end as promised.

    The war in the Middle East is still raging.

    Grocery prices did not go down on day one, and some goods cost more because of tariffs.

    As for the promise of a new age of American prosperity, there’s no rainbow in sight yet, although there is a pot of gold in the White House, with estimates of billions in profits for Trump family businesses since he took office,

    But for all of that, along with an approval rating that has dropped since he took office in January, Trump exudes confidence. So much so that he proudly wears that bright red hat, which he was giving out in the Oval office, and which retails for $25.

    It’s another ingenious economic stimulation plan.

    And there’s an important lesson here for all of us.

    Never admit defeat, and when things don’t go your way, stand tall, adjust your hat, and find someone to blame.

    We should all have our own hats made.

    Doctors could wear hats saying they’ve never gotten a diagnosis wrong.

    Dentists could wear hats saying they’ve never pulled the wrong tooth.

    TV meteorologists could wear hats saying — well, maybe not — that they’ve gotten every forecast right.

    I’m having hats made as you read this.

    LOPEZ IS RIGHT ABOUT EVERYTHING!

    Please don’t have me fired, Mr. President, if you disagree.

    As for Jimmy Kimmel, I’m offering this idea free of charge:

    If you ever get your job back, you, your sidekick Guillermo, and the entire studio audience should be wearing hats.

    KIMMEL WAS RIGHT ABOUT EVERYTHING!

  • Humanity is rapidly depleting water and much of the world is getting drier

    [ad_1]

    For more than two decades, satellites have tracked the total amounts of water held in glaciers, ice sheets, lakes, rivers, soil and the world’s vast natural reservoirs underground — aquifers. An extensive global analysis of that data now reveals fresh water is rapidly disappearing beneath much of humanity’s feet, and large swaths of the Earth are drying out.

    Scientists are seeing “mega-drying” regions that are immense and expanding — one stretching from the western United States through Mexico to Central America, and another from Morocco to France, across the entire Middle East to northern China.

    There are two primary causes of the desiccation: rising temperatures unleashed by using oil and gas, and widespread overpumping of water that took millennia to accumulate underground.

    “These findings send perhaps the most alarming message yet about the impact of climate change on our water resources,” said Jay Famiglietti, a hydrologist and professor at Arizona State University who co-authored the study. “The rapid water cycle change that the planet has experienced over the last decade has unleashed a wave of rapid drying.”

    Since 2002, satellites have measured changes in the Earth’s gravity field to track shifts in water, both frozen and liquid. What they sent back shows that nearly 6 billion people — three-fourths of humanity — live in the 101 countries that have been losing water.

    Each year, these drying areas have been expanding by an area roughly twice the size of California.

    Canada and Russia, where large amounts of ice and permafrost are melting, are losing the most fresh water. The United States, Iran and India also rank near the top, with rising temperatures and chronic overuse of groundwater.

    Farms and cities are pulling up so much water using high-capacity pumps that much of the water evaporates and eventually ends up as rain falling over the ocean, measurably increasing sea level rise.

    The study, published in the journal Science Advances, found that these water losses now contribute more to sea level rise than the more widely understood melting of mountain glaciers or the Antarctic or Greenland ice sheets.

    The staggeringly rapid expansion of the drying regions was surprising even for the scientists. Famiglietti said it is set to worsen in many areas, leading to “widespread aridification and desertification.”

    “We found tremendous growth in the world’s land areas that are experiencing extreme drought,” Famiglietti said. “Only the tropics are getting wetter. The rest of the world’s land areas are drying.”

    The wave of drying has prompted many people across the world’s food-growing regions to drill more wells and rely more heavily on pumping groundwater.

    The researchers estimate that 68% of the water the continents are losing, not including melting glaciers, is from groundwater depletion. And much of that water is to irrigate crops.

    Where aquifer levels decline, wells and faucets increasingly sputter and run dry, people drill deeper and the land can sink as underground spaces collapse.

    The loss may be irreversible, leaving current and future generations with less water.

    Famiglietti said the potential long-term consequences are dire: Farmers will struggle to grow as much food, economic growth will be threatened, increasing numbers of people will flee drying regions, conflicts over water are already increasing, and more governments will be destabilized in countries that aren’t prepared.

    The researchers estimated that the world’s drying regions have been losing 368 billion metric tons of water per year. That’s more than double the volume of Lake Tahoe, or 10 times Lake Mead, the largest reservoir in the United States.

    All that water, year after year, has become a major contributor to sea level rise, which is projected to cause worsening damages in the coming decades.

    Previous studies have shown dropping groundwater levels, dry regions getting drier and these water losses contributing to sea level rise. But the new study shows these changes are happening faster and on a larger scale than previously known.

    “It is quite alarming,” said Hrishikesh Chandanpurkar, an Arizona State research scientist who co-authored the study. “Water touches everything in life. The effects of its irreversible decline are bound to trickle into everything.”

    He likened the global situation to a family overspending and drawing down their savings accounts.

    “Our bank balance is consistently decreasing. This is inherently unsustainable,” Chandanpurkar said.

    The draining of groundwater, often invisible, hides how much arid regions are drawing down their reserve accounts, he said. “Once these trust funds dry out, water bankruptcy is imminent.”

    The researchers examined data from two U.S.-German satellite missions, called Gravity Recovery and Climate Experiment (GRACE) and GRACE-Follow On.

    The scientists ranked California’s Central Valley as the region where the fastest groundwater depletion is occurring, followed by parts of Russia, India and Pakistan.

    In other research, scientists have found that the last 25 years have probably been the driest in at least 1,200 years in western North America.

    Over the last decade, groundwater losses have accelerated across the Colorado River Basin.

    And farming areas that a decade ago appeared in the satellite data as hot spots of drought and groundwater depletion, such as California’s Central Valley and the Ogallala Aquifer beneath the High Plains, have expanded across the Southwest, through Mexico and into Central America.

    The satellite data show that these and other regions are not only shifting to drier conditions on average, but are also failing to “live within the means” of the water they have available, Chandanpurkar said.

    “The truth is, water is not being valued and the long-term reserves are exploited for short-term profits,” he said.

    He said he hopes the findings will prompt action to address the chronic overuse of water.

    In the study, the researchers wrote that “while efforts to slow climate change may be sputtering,” people urgently need to take steps to preserve groundwater. They called for national and global efforts to manage groundwater and “help preserve this precious resource for generations to come.”

    In many areas where groundwater levels are dropping, there are no limits on well-drilling or how much a landowner can pump, and there is no charge for the water. Often, well owners don’t even need to have a meter installed or report how much water they’re using.

    In California, farms producing vast quantities of nuts, fruits and other crops have drawn down aquifers so heavily that several thousand rural households have had their wells run dry over the last decade, and the ground has been sinking as much as 1 foot per year, damaging canals, bridges and levees.

    The state in 2014 adopted a landmark groundwater law that requires local agencies to curb widespread overpumping. But it gives many areas until 2040 to address their depletion problems, and in the meantime water levels have continued to fall.

    State officials and local agencies have begun investing in projects to capture more stormwater and replenish aquifers.

    Arizona has sought to preserve groundwater in urban areas through a 1980 law, but in much of the state, there are still no limits on how many wells can be drilled or how much water can be pumped. Over the last decade, out-of-state companies and investors have drilled deep wells and expanded large-scale farming operations in the desert to grow hay and other crops.

    Famiglietti, who was previously a senior water scientist at NASA’s Jet Propulsion Laboratory, has extensively studied groundwater depletion around the world. He said he doesn’t think the leaders of most countries are aware of, or preparing for, the worsening crisis.

    “Of all the troubling findings we revealed in the study, the one thing where humanity can really make a difference quickly is the decision to better manage groundwater and protect it for future generations,” Famiglietti said. “Groundwater will become the most important natural resource in the world’s drying regions. We need to carefully protect it.”

  • Energy secretary says Trump administration may alter past National Climate Assessments

    [ad_1]

    U.S. Energy Secretary Chris Wright said this week that the Trump administration plans to review and potentially alter the nation’s climate science reports.

    In a Tuesday appearance on CNN’s “The Source,” Wright told CNN host Kaitlan Collins the National Climate Assessments have been removed from government websites “because we’re reviewing them.”

    “We will come out with updated reports on those and with comments on those,” Wright said.

    The National Climate Assessments are mandated by Congress and have been released five times since 2000. The federal reports, prepared by hundreds of volunteer scientists, are subject to extensive peer review and detail how climate change is affecting each region of the United States so far and provide the latest scientific forecasts.

    Wright accused the previous reports of being politically biased, stating that they “are not fair assessments of the data.”

    “When you get into departments and look at stuff that’s there and you find stuff that’s objectionable, you want to fix it,” he said.

    His statements came after the Trump administration in April dismissed more than 400 experts who had already started work on the sixth National Climate Assessment, due for publication in late 2027 or early 2028. The administration in July also removed the website of the U.S. Global Change Research Program, which housed the reports.

    The move marks the latest escalation in the Trump administration’s efforts to downplay climate science. The president and Department of Energy in recent months have championed fossil fuel production and slashed funding and incentives for renewable energy projects. This week, the Energy Department posted an image of coal on X alongside the words, “She’s an icon, she’s a legend, and she is the moment.”

    Meanwhile, the U.S. Environmental Protection Agency has proposed looser regulations for polluting sectors such as power plants and vehicles. EPA Administrator Lee Zeldin in March proclaimed the administration was “driving a dagger straight into the heart of the climate change religion.”

    In his CNN appearance, Wright said the previous climate change assessments — including the 2018 report prepared during Trump’s first term — were not “a reasonable representation of broad climate science.”

    “They have been more politically driven to hype up a real issue, but an issue that’s just nowhere near the world’s greatest challenge,” he said of climate change. “Nobody’s who’s a credible economist or scientist believes that it is, except a few activists and alarmists.”

    Environmental experts were concerned by Wright’s comments.

    “Secretary Wright just confirmed our worst fears — that this administration plans to not just bury the scientific evidence but replace it with outright lies to downplay the worsening climate crisis and evade responsibility for addressing it,” said Rachel Cleetus, policy director for the Climate and Energy Program at the Union of Concerned Scientists, who was among the authors dismissed by the administration.

    “This is one more alarming example of the Trump administration’s ongoing and highly politicized effort to obfuscate scientific truth to further its dangerous and deadly pro-fossil fuel agenda,” Cleetus said.

    The Energy Department last week also released its own climate report, commissioned by Wright, that questions the severity of climate change.

    “Both models and experience suggest that [carbon dioxide]-induced warming might be less damaging economically than commonly believed, and excessively aggressive mitigation policies could prove more detrimental than beneficial,” the report says.

    Daniel Swain, a climate scientist with the University of California Agriculture and Natural Resources, noted in a post on X that the previous National Climate Assessments were authored by hundreds of scientists who were leading domain experts in their fields.

    “This would mark an extraordinary, unprecedented, and alarming level of interference in what has historically been a fair and systematic process,” Swain said of the possibility that previous reports could be altered.

    The Department of Energy did not immediately respond to a request for comment.

    Summer of 2023 was hottest in 2,000 years, study finds

    [ad_1]

    An extreme summer marked by deadly heat waves, explosive wildfires and record-warm ocean temperatures will go down as among the hottest in the last 2,000 years, new research has found.

    The summer of 2023 saw the temperature in the Northern Hemisphere soar 3.72 degrees above the average from 1850 to 1900, when modern instrumental recordkeeping began, according to a study published Tuesday in the journal Nature. The study focused on surface air temperatures across the extra-tropical region, which sits at 30-90 degrees north latitude and includes most of Europe and North America.

    June, July and August last year were also 3.96 degrees warmer than the average from the years 1 through 1890, which the researchers calculated by combining observed records with tree ring records from nine global regions.

    Jan Esper, the study’s lead author and a professor of climate geography at Johannes Gutenberg University in Germany, said that he was not expecting summer last year to be quite so anomalous, but that he was ultimately not surprised by the findings. The high temperatures built on an overall warming trend driven by greenhouse gas emissions and were further amplified by the onset of El Niño in the tropical Pacific.

    “It’s no surprise — this really, really outstanding 2023 — but it was also, step-wise, a continuation of a trend that will continue,” Esper told reporters Monday. “Personally I’m not surprised, but I am worried.”

    He said it was important to place 2023’s temperature extreme in a long-term context. The difference between the region’s previous warmest summer, in the year 246, and the summer of 2023 is 2.14 degrees, the study found.

    The heat is even more extreme when compared with the region’s coldest summers — the majority of which were influenced by volcanic eruptions that spewed heat-blocking sulfur into the stratosphere. According to the study, 2023’s summer was 7.07 degrees warmer than the coldest reconstructed summer from this period, in the year 536.

    “Although 2023 is consistent with a greenhouse gases-induced warming trend that is amplified by an unfolding El Niño event, this extreme emphasizes the urgency to implement international agreements for carbon emission reduction,” the study says.

    The sweltering summer temperatures contributed to scores of heat illnesses and deaths, including at least 645 heat-associated deaths in Maricopa County, Ariz., where Phoenix saw temperatures of 110 degrees or hotter for a record 31 consecutive days.

    Wildfires exacerbated by high temperatures raged across Canada and sent hazardous smoke down the East Coast of the United States and across the Atlantic. Meanwhile, ocean temperatures off the coast of Florida soared above 101 degrees, the temperature of a hot tub.

    Multiple climate agencies, including the National Oceanic and Atmospheric Administration and the European Union’s Copernicus Climate Change Service, declared 2023 the hottest year on record globally.

    Notably, Copernicus found that the summer months of June, July and August last year measured 1.18 degrees warmer than average — still hot, but not nearly as warm as the study’s findings for the Northern Hemisphere’s extra-tropical region.

    That region was especially hot in part because it is home to so much land, which warms faster than oceans, said Karen McKinnon, an assistant professor of statistics and the environment at UCLA who did not work on the study. (June, July and August are also winter months in the Southern Hemisphere.)

    McKinnon said the study’s findings are not unexpected, as there was already good evidence that the summer of 2023 was record-breaking when compared with measurable data going back to the mid-1800s. But by going back 2,000 years, the researchers also helped illuminate “the full range of natural variability that could have occurred in the past,” she said.

    She noted that tree rings can serve as a helpful proxy for climate conditions in the past, as trees tend to grow more in a given year if they receive the right amount of warmth, water and sunshine.

    But although last year’s heat was undeniable, the study also underscores that the summer temperature in this region was notably higher than the global target of 2.7 degrees — or 1.5 degrees Celsius — of warming over the preindustrial period, which was established by the Intergovernmental Panel on Climate Change in 2015.

    It also notes that some recent research has found the data used to calculate that baseline may be off by several tenths of a degree, meaning it could need to be recalibrated, with the target landing closer to an even more challenging 1.6 or 1.7 degrees.

    “I don’t think we should use the proxy instead of the instrumental data, but there’s a good indication that there’s a warm bias,” Esper said. “Further research is needed.”

    McKinnon said there is always going to be some degree of uncertainty when comparing present-day temperatures to past temperatures, but that the 1.5-degree limit is as symbolic as it is literal. Many effects of climate change, including worsening heat waves, have already begun.

    “There are definitely tipping points in the climate system, but we don’t understand the climate system well enough to say 1.5 C is the temperature for certain tipping points,” she said. “This is just a policy goal that gives you a temperature change that maybe would be consistent with averting some damages.”

    In fact, the study’s publication comes days after a survey of 380 leading scientists from the IPCC revealed deep concerns about the world’s ability to limit global warming to 1.5 degrees. That report, published last week in the Guardian, found that only 6% of surveyed scientists think the 1.5-degree limit will be met. Nearly 80% said they foresee at least 2.5 degrees Celsius of warming.

    The report caused a stir among the scientific community, with some saying it focused too heavily on pessimism and despair. But Daniel Swain, a climate scientist with UCLA who participated in the survey, said its findings are worthy of consideration.

    “There are many kinds of scientists, myself included, who are very worried and concerned and increasingly alarmed by what is going on and what the data is showing,” Swain said during a briefing Friday. “But if anything, I think that really results in a stronger sense of resolve and urgency to do even more, and to do better.”

    Indeed, while scientists continue to weigh in on whether — or how quickly — humanity can alter the planet’s worsening warming trajectory, Esper said he hopes the latest study will serve as motivation for changing outdated modes of energy consumption that contribute to planet-warming greenhouse gases.

    “I am concerned about global warming — I think it’s one of the biggest threats out there,” he said.

    He added that he is particularly worried for his children and for younger generations who will bear the brunt of worsening heat and other adverse climate outcomes. There is a strong likelihood that the summer of 2024 will be even hotter, the study says.

    “The longer we wait, the more extensive it will be, and the more difficult it will be to mitigate or even stop that process and reverse it,” Esper said. “It’s just so obvious: We should do as much as possible, as soon as possible.”

    WTF Fun Fact 13726 – The Word Scientist

    [ad_1]

    The word “scientist” originated in the 19th century when William Whewell, a Cambridge historian and philosopher, sought to create a unifying term for those engaged in the sciences. Before this, various terms like “natural philosopher” and “savant” were used.

    Whewell considered several options before settling on “scientist,” inspired by the word “artist.” This designation emphasized the interconnectedness of different scientific disciplines and reflected the artistry involved in scientific discovery.

    In a short time, “scientist” became widely accepted and shaped how we perceive scientific professions today.

    The Birth of a New Term

    Before “scientist,” the field of science didn’t have a unified term to describe its practitioners. Individuals like Isaac Newton or Charles Darwin were referred to as “natural philosophers,” which suggested their work was rooted in philosophy rather than practical science. Other terms like “savant” and the German “naturforscher” were floated but never gained traction.

    William Whewell’s Contribution

    William Whewell, known for his contributions to multiple disciplines, sought to encapsulate the essence of scientific exploration. His work on “The Philosophy of the Inductive Sciences” paved the way for standardizing scientific methods and terminology. The idea was to encapsulate scientific disciplines into one collective term that reflected the exploratory nature of science.

    Whewell suggested “scientist” to refer to those who engage in scientific inquiry, much like “artist” describes those involved in artistic pursuits. Initially, he was concerned that the term sounded too close to “economist” or “atheist,” both having negative connotations in that era. However, he decided to adopt it, and the term quickly caught on, symbolizing a new identity for those exploring various scientific disciplines.

    The Legacy of the Word Scientist

    The term “scientist” has since gained universal acceptance and shaped how the world perceives individuals in this field. It emphasizes the unity among diverse scientific disciplines and acknowledges the creativity and ingenuity in scientific research.

  • Scientists say these killer whales are distinct species. It could save them

    Scientists say these killer whales are distinct species. It could save them

    [ad_1]

    More than 150 years ago, a San Francisco whaler noticed something about killer whales that scientists may be about to formally recognize — at least in name.

    Charles Melville Scammon submitted a manuscript to the Smithsonian in 1869 describing two species of killer whales inhabiting West Coast waters.

    Now a new paper published in Royal Society Open Science uses genetic, behavioral, morphological and acoustic data to argue that the orcas in the North Pacific known as residents and transients are different enough to be distinct species. They propose using the same scientific names Scammon is believed to have coined in the 19th century.

    Aggressive and impactful reporting on climate change, the environment, health and science.

    Killer whales, found in all oceans, are currently considered one global species. The new proposed species would mark the first split of the ferocious apex predators, which, if approved, could have significant conservation and scientific implications — in addition to furthering a decades-long quest to properly classify the whales.

    The two proposed species may look indistinguishable to the untrained eye, but there are subtle differences in their fins and markings — and many more unseen ones. They don’t speak the same “language” or nosh on the same food. And they have no interest in hanging out with one another, despite often dwelling in the same waters. Most significantly, researchers say, their DNA shows clear distinction.

    Transients — also called Bigg’s killer whales — hunt seals and other marine mammals in small packs in expansive waters stretching from Southern California to the Arctic Circle. And they’re not very chatty while they sneak up on prey — they need to maintain stealth. They sport pointy, triangle-shaped dorsal fins with a solid white “saddle patch” behind it.

    Residents, meanwhile, stick to fish — primarily Chinook salmon. They love to gab and hang out with the family. In fact, most offspring stay with their mothers their entire lives. Because fish don’t hear very well, they’re free to chatter as they chow down. Residents hew closer to coastlines, from Central California to southeast Alaska, where salmon congregate. Their fins tend to curve back toward the tail and intrusions of black sometimes extend into their saddle patches.

    A third type of killer whale roams the Pacific, but less is known about it; these offshore whales live farther out and prey on sharks and other large fish. A recent study found evidence of another, previously unknown group in the open ocean.

    Taxonomy, the scientific discipline of naming and classifying animals, is how we break down critters into species. It’s an intellectual exercise that has real-world consequences.

    “We’re facing a global conservation crisis, losing species that we don’t even know exist,” said Phillip Morin, the new study’s lead author and a marine mammal geneticist at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center.

    If you think of killer whales as one species — a big pie — then killing some of them off here might not be a cause for concern, Morin said. But if you start parsing out species and subspecies — slices of the pie — then it’s suddenly possible to lose a unique, irreplaceable group.

    A portion of the fish-eating resident killer whales — known as Southern Residents — is already listed as endangered in the U.S. and Canada. Salmon depletion from overfishing and habitat destruction has starved them, and only about 75 are left now. But if they’re designated as part of a species, the International Union for Conservation of Nature will assess them (and transients) separately.

    Study co-author Thomas Jefferson, a marine mammal biologist, also with NOAA’s Southwest Fisheries Science Center in La Jolla, believes the residents would probably be categorized on the conservation union’s Red List as threatened or endangered, possibly even critically endangered.

    About 20 years ago, when Morin first began his foray into the world of marine mammal genetics, he said there was agreement that the taxonomy of cetaceans — which includes whales, dolphins and porpoises — was “really poor.”

    Classification of land animals is often done by measuring bones, but water dwellers are hard to collect and store. Researchers don’t have extensive collections of whale skulls in museums from around the world, and it isn’t necessarily ethical to acquire them. They needed other tools — such as better genetics, drone recordings and satellite tagging — which didn’t exist yet.

    “The genetics has now finally come to the point where we can do this on a broad scale and get the kind of resolution and information that we didn’t have,” Morin said.

    Over two decades, researchers went from analyzing thousands to billions of base pairs of DNA from individual killer whales. The enhanced detail has allowed scientists to “look back through time,” Morin said, and answer questions about which killer whale populations are closely related — or not — and when differences emerged.

    Based on their genetic analyses, Morin and his team estimate that transients diverged from other orcas between 200,000 and 300,000 years ago, while residents began to split off about 100,000 years ago.

    Only a small tissue sample is needed to analyze killer whale DNA to tell a big genetic story.

    “We can actually go out with a crossbow and collect a little teeny bit of tissue from a living whale — just shoot a little dart at it and collect a little bit of skin,” Jefferson said.

    Of course, scientists in the 19th century dedicated to describing and categorizing whales didn’t have access to this cutting-edge technology.

    Virtually nothing was known about marine mammals of the West Coast of North America in the mid-1800s, when Charles Melville Scammon, the whaler, began meticulously documenting and measuring cetaceans, Jefferson said. (Scammon bears no relation to Herman Melville, author of whale-centric “Moby Dick.”)

    When Scammon’s paper from 1869 describing a variety of cetaceans of the West Coast, including orcas, made it to the Smithsonian, he had “every reason to believe that his article would be well received,” according to “Beyond the Lagoon,” a biography of the seaman. He knew things no other zoologist did because of his proximity to the whales and keen eye.

    In a paper penned three years later, Scammon paints a vivid picture of killer whales, from their “beautifully smooth and glossy skin” to their “somewhat military aspect,” even including drawings. He recounts a gruesome attack, seen in “Lower California,” by a trio of killer whales on a gray whale and her baby.

    The orcas assaulted the pair for at least an hour, eventually killing the younger whale while exhausting the mother. “As soon as their prize had settled to the bottom, the trio band descended, bringing up large pieces of flesh in their mouths, which they devoured after coming to the surface,” Scammon wrote. “While gorging themselves in this wise, the old whale made her escape, leaving a track of gory water behind.”

    What Scammon didn’t know was that his earlier manuscript would fall into the hands of Edward Drinker Cope, a naturalist who had a reputation for being overly ambitious and warring with colleagues for credit.

    Cope, secretary of the Academy of Natural Sciences of Philadelphia, slapped his own introduction on the paper with descriptions and Latin names of the orcas inhabiting the Northern Pacific.

    Because of rules governing the scientific naming of animals, Cope would forever be credited with the names believed to have been chosen by Scammon. Nevermind that Cope probably never saw a living killer whale.

    The paper also misidentified Scammon and gave him little credit. When the whaler saw it, he was furious, according to the biography.

    “It‘s a really, really strange and very weird and dramatic episode in the history of marine mammal biology, how these names came about,” Jefferson said.

    Many of Scammon’s observations turned out to be erroneous. Often he logged differences between male and female killer whales rather than differences between species, said Michael Milstein, a spokesperson for NOAA. But his inquiry set the stage for more rigorous research to come.

    Morin and his research team propose using the same Latin names from more than a century ago for the species they identified in their recent study.

    The researchers call transients Orcinus rectipinnus, noting that, in Latin, “recti means right or upright, and pinna means fin, feather, or wing, most likely referring to the tall erect dorsal fin of males.”

    Residents, meanwhile, are labeled Orcinus ater. Ater means black or dark, according to the study, “which probably refers to the largely black color of this species.”

    All killer whales are currently classified as Orcinus orca, a macabre nod to their vicious reputation. Some say Orcinus means “of the kingdom of the dead,” a reference to Orcus, a Roman god of the underworld.

    There are also common, or informal names, to consider.

    The researchers suggest sticking with “Bigg’s” for transients, honoring Michael Bigg, the father of modern-day orca research.

    The team plans to consult tribes who have a connection to the resident whales, including the Lummi Nation and Tulalip tribes of the Northwest, before settling on a common name, according to Milstein.

    “They decided not to try to rush it to match the paper, but to take the time to make sure it is done in a way that everyone understands and believes in,” Milstein said.

    John Durban, an associate professor with Oregon State University’s Marine Mammal Institute and co-author of the new study, said he supports using the name “Blackfish,” which is used by some tribes in the Pacific Northwest.

    Complex rules govern the discipline of taxonomy, and typically a specimen must be designated as a reference point when it’s first named.

    However, the original specimens studied by Scammon were destroyed or disappeared. According to Jefferson, one at the California Academy of Sciences in San Francisco was wiped out by the historic 1906 earthquake and subsequent fire. Another, believed to have been in Scammon’s personal possession, can’t be found.

    So the researchers found stand-ins at the Smithsonian.

    Whether the broader community of marine mammal biologists will accept the researchers’ findings — and adopt Scammon’s and Cope’s names — will soon be determined.

    The proposal is slated to go before a committee from the Society for Marine Mammalogy, which will vote in a few months on whether to greenlight designation of the species. Jefferson and another author of the new study sit on the committee and will recuse themselves from the vote.

    Even today, Scammon has to contend with detractors.

    Robert Pitman, a marine ecologist with Oregon State University who was not involved in the study, isn’t “entirely happy” with the names put forth.

    The names were conceived “before science, by and large, especially biological science, had any rigor,” Pitman said. “And then the descriptions that [Scammon] puts with those names are just so vague. I’m kind of doubtful that those names will stand.”

    Names aside, he expects most marine mammalogists will be on board with the proposed species; many have suspected species-level differences among the well-studied whales of the Pacific Northwest. He said the case for splitting off the mammal-eating transients is particularly strong.

    The newly identified species are believed to be harbingers of more to come.

    Pitman, who has studied killer whales in Antarctica for over 10 years, said there’s a similar divide between mammal- and fish-eating killer whales in those waters.

    There are five identified types, and Pitman thinks at least one will turn out to be a different species. Some look dramatically different.

    “And it’ll probably be easier now that somebody’s already made the first step in saying, ‘There’s more than one species out there.’”

  • NASA finally figures out how to open a $1-billion canister

    NASA finally figures out how to open a $1-billion canister

    [ad_1]

    Late last year, a spacecraft containing samples of a 4.6-billion-year-old asteroid landed safely in the desert after a 1.2-billion mile journey. There was only one little problem: NASA couldn’t get the canister containing its prized rocks open.

    After months of tinkering, scientists at NASA’s Johnson Space Center in Houston finally dislodged two stuck fasteners that had kept the pieces of the asteroid Bennu out of researchers’ hands.

    “It’s open! It’s open!” NASA’s Planetary Science Division posted Friday on X, along with a photograph of the slate-colored bounty of dust and small rocks inside the canister.

    Scientists had to switch course on the canister opening effort in mid-October after it became clear that none of the items in NASA’s box of approved tools could force open the last two of 35 fasteners sealing the canister.

    To prevent the sample from being contaminated by Earthly air, it has been stored in a clean room in the Houston facility where hazmat-suited curators delicately dismantled the canister. The team custom-designed new tools to pry open the final latches.

    The agency will now finish extracting the approximately 9-ounce sample, which will be weighed and chemically analyzed. Much of the payload from OSIRIS-REx (an acronym for Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) will then be frozen and carefully preserved so that future generations of scientists will be able to study it with advanced technologies.

    “We are overjoyed with the success,” NASA’s chief OSIRIS-REx sample curator, Nicole Lunning, said in a statement.

    It took more than seven years and roughly $1 billion to bring back a sample from Bennu, a space rock formed during the earliest days of the solar system. The asteroid samples found on Earth have essentially been cooked by their searing journey through the atmosphere, which limits what scientists can learn from them.

    With OSIRIS-REx, “the objective is to bring back an ancient piece of the early solar system that is pristine,” NASA astrobiologist Jason Dworkin told The Times in September. “You can use these leftovers of the formation of the solar system to construct what happened in that formation.”

    The spacecraft that collected the sample in 2020 and released it toward Earth in September is now heading on to its next mission. The craft, now named OSIRIS-APophis EXplorer, or OSIRIS-APEX, is on its way to a peanut-shaped asteroid named Apophis.

    For a short (but alarming) time, astronomers thought Apophis might be on track to smash disastrously into Earth. Now that that worrying possibility has been ruled out, scientists are eagerly looking ahead to 2029, when the asteroid will pass closer to Earth than any object of its size ever has.

    “It’s something that almost never happens, and yet we get to witness it in our lifetime,” JPL navigation engineer Davide Farnocchia said last year. “We usually send spacecraft out there to visit asteroids and find out about them. In this case, it’s nature doing the flyby for us.”

    Born in Venezuela, developmental and molecular biologist Alejandro Sánchez Alvarado receives the $100,000 prize for his contributions to the field of regeneration.

    Press Release


    Feb 22, 2023 10:45 EST

    For his contributions to the field of regeneration, Alejandro Sánchez Alvarado receives the Vilcek Prize in Biomedical Science. The Vilcek Prize in Biomedical Science is a $100,000 prize awarded annually by the Vilcek Foundation as part of its prizes program. 

    Awarded annually since 2006, the Vilcek Foundation prizes recognize and celebrate immigrant contributions to scientific research and discovery, and to artistic and cultural advancement in the United States. The prizes provide direct support to individual immigrant scientists and artists and help to raise greater public awareness of the value of immigration for a robust society. In 2023, the Vilcek Foundation awards four prizes in Biomedical Science, comprising the $100,000 Vilcek Prize and three $50,000 prizes—the Vilcek Prizes for Creative Promise in Biomedical Science. 

    Born in Caracas, Venezuela, molecular and developmental biologist Alejandro Sánchez Alvarado grew up using the scientific method to understand the things that fascinated him in the natural world. As a budding scientist, Sánchez Alvarado moved to the United States to pursue studies in molecular biology at Vanderbilt University in Nashville, Tennessee. Now a leader in the field of regeneration, he is the executive director and chief scientific officer of the Stowers Institute for Medical Research in Kansas City, Missouri.

    “Through the combination of rigorous research and new tools and technologies, Alejandro Sánchez Alvarado has worked to illuminate the important functions that epigenetics and signaling have on the process of regeneration,” says Vilcek Foundation Chairman and CEO Jan Vilcek. “His work has important implications on the understanding of cellular and organismal regeneration, and holds enormous promise for our further understanding of core biological concepts.”

    Says Vilcek Foundation President Rick Kinsel, “Research Institutions in the United States have drawn scientists from around the globe, and many groundbreaking discoveries in research and development in biology, physics, and medicine have been by immigrant scientists. The perspective and insight that foreign-born scientists bring to research and development, and the value of diversity in seeking answers to science and medicine’s most perplexing questions, cannot be overstated.”

    Sánchez Alvarado credits being an immigrant and being bilingual as having a profound impact on his work as a scientist, noting how the syntax interpretations of problems or ideas in two different languages—English and Spanish—help him to form more nuanced ideas and hypotheses. “Because every language is an interpretation of the universe, the more interpretations one has access to, the richer our comprehension of the world becomes,” he says. 

    He also reflects on the sacrifices that immigrants make to pursue the subjects and work they are passionate about in the United States. “We left everything behind to pursue an idea,” he says. “[We were] not looking for fame or fortune. [We] are looking for answers to questions.” 

    As part of the Vilcek Foundation’s prizes campaign, the foundation has published a biographical profile and video highlighting Sánchez Alvarado’s life and work on the Vilcek Foundation website, Alejandro Sánchez Alvarado: “Making the improbable possible.”

    The Vilcek Foundation

    The Vilcek Foundation raises awareness of immigrant contributions in the United States and fosters appreciation of the arts and sciences. The foundation was established in 2000 by Jan and Marica Vilcek, immigrants from the former Czechoslovakia. The mission of the foundation was inspired by the couple’s respective careers in biomedical science and art history. Since 2000, the foundation has awarded over $7 million in prizes to foreign-born individuals and supported organizations with over $6 million in grants.

  • Was the COVID Toilet Panic Overblown?

    Was the COVID Toilet Panic Overblown?

    [ad_1]

    In the dark early days of the pandemic, when we knew almost nothing and feared almost everything, there was a moment when people became very, very worried about toilets. More specifically, they were worried about the possibility that the cloud of particles toilets spew into the air when flushed—known in the scientific literature as “toilet plume”—might be a significant vector of COVID transmission. Because the coronavirus can be found in human excrement, “flushing the toilet may fling coronavirus aerosols all over,” The New York Times warned in June 2020. Every so often in the years since, the occasional PSA from a scientist or public-health expert has renewed the scatological panic.

    In retrospect, so much of what we thought we knew in those early days was wrong. Lysoling our groceries turned out to not be helpful. Masking turned out to be very helpful. Hand-washing, though still important, was not all it was cracked up to be, and herd immunity, in the end, was a mirage. As the country shifts into post-pandemic life and takes stock of the past three years, it’s worth asking: What really was the deal with toilet plume?

    The short answer is that our fears have not been substantiated, but they weren’t entirely overblown either. Scientists have been studying toilet plume for decades. They’ve found that plumes vary in magnitude depending on the type of toilet and flush mechanism. Flush energy plays a role too: The greater it is, the larger the plume. Closing the lid (if the toilet has one) helps a great deal, though even that cannot completely eliminate toilet plume—particles can still escape through the gap between the seat and the lid.

    Whatever the specifics, the main conclusion from years of research preceding the pandemic has been consistent and disgusting: “Flush toilets produce substantial quantities of toilet plume aerosol capable of entraining microorganisms at least as large as bacteria … These bioaerosols may remain viable in the air for extended periods and travel with air currents,” scientists at the CDC and the University of Oklahoma College of Public Health wrote in a 2013 review paper titled “Lifting the Lid on Toilet Plume Aerosol.” In other words, when you flush a toilet, an unsettling amount of the contents go up rather than down.

    Knowing this is one thing; seeing it is another. Traditionally, scientists have measured toilet plume with either a particle counter or, in at least one case, “a computational model of an idealized toilet.” But in a new study published last month, researchers at the University of Colorado at Boulder took things a step further, using bright-green lasers to render visible what usually, blessedly, is not. John Crimaldi, an engineering professor and a co-author of the study, who has spent 25 years using lasers to illuminate invisible phenomena, told me that he and his colleagues went into the experiment fully expecting to see something. Even so, they were “completely caught off guard” by the results. The plume was bigger, faster, and more energetic than they’d anticipated—“like an eruption,” Crimaldi said, or, as he and his colleagues put it in their paper, a “strong chaotic jet.”

    Within eight seconds, the resulting cloud of aerosols shoots nearly five feet above the toilet bowl—that is, more than six feet above the ground. That is: straight into your face. After the initial burst, the plume continues to rise until it hits the ceiling, and then it wafts outward. It meets a wall and runs along it. Before long, it fills the room. Once that happens, it hangs around for a while. “You can sort of extrapolate in your own mind to walking into a public restroom in an airport that has 20 toilet stalls, all of them flushing every couple minutes,” Crimaldi said. Not a pleasant thought.

    The question, then, is not so much whether toilet plume happens—like it or not, it clearly does—as whether it presents a legitimate transmission risk of COVID or anything else. This part is not so clear. The 2013 review paper identified studies of the original SARS virus as “among the most compelling indicators of the potential for toilet plume to cause airborne disease transmission.” (The authors also noted, in a dry aside, that although SARS was “not presently a common disease, it has demonstrated its potential for explosive spread and high mortality.”) The one such study the authors discuss explicitly is a report on the 2003 outbreak in Hong Kong’s Amoy Gardens apartment complex. That study, though, is far from conclusive, Mark Sobsey, an environmental microbiologist at the University of North Carolina at Chapel Hill, told me. The researchers didn’t rule out other modes of transmission, nor did they attempt to culture live virus from the fecal matter—a far more reliable indicator of infectiousness than mere detection.

    Beyond that, Sobsey said, there is little evidence that toilet plumes spread SARS or COVID-19. In his own review, published in December 2021, Sobsey found “no documented evidence” of viral transmission via fecal matter. This, at least, seems to track with the three years of pandemic experience we’ve all now endured. Although we can’t easily prove that bathrooms don’t play a significant role in spreading COVID-19, we haven’t seen any glaring indications that they do. And anyway, the coronavirus has found plenty of other awful ways to spread.

    Just because toilet plume doesn’t seem to be a vector of COVID transmission, though, doesn’t mean you can forget about it. Gastrointestinal viruses such as norovirus, Sobsey told me, present a more serious risk of transmission via toilet plume, because they are known to spread via fecal matter. The only real solutions are structural. Improved ventilation would keep aerosolized waste from building up in the air, and germicidal lighting, though the technology is still being developed, could potentially disinfect what remains. Neither, however, would stop the plume in the first place. To do that, you would need to change the toilet itself: In order to create a smoother and thus better-contained flush, you could change the geometry of the bowl, the way the water enters and exits, or any number of other variables. Toilet manufacturers could also, you know, stop producing lidless toilets.

    But none of that will save you the next time you find yourself staring into a toilet’s blank maw.
