    QUIZ: President Trump is bringing back the Presidential Fitness Test. How much do you remember?

    – If you ever get sidelined by cramps, injury, or if you’re new to running and want to understand how your body moves, fitness tests are a great tool to become better, faster, and stronger. Let’s break down what tests are beneficial for runners? A gait analysis, which involves being recorded from different angles while running on a treadmill to look at form, including foot strike and body alignment, is especially useful for runners with chronic injuries like shin splints, patella femoral pain, or IT band issues. If you’re new to running, consider a functional movement screening, or FMS, which is when a coach or a trainer will typically put you through movements like single leg squat, push up, and step over, and then watch how your body moves. If your hip drops to one side or your knees cave in on that squat, then that could indicate weakness in your core stability. Some places like NYU, HSS and Columbia Run Lab offer running analyses, which combine a gate analysis on a treadmill with a movement screen like the FMS, so it’s one stop shopping. You can also often get an FMS at a gym as part of an initial training evaluation, and it can be useful on its own. If you wanna measure your cardio fitness, VO2 max is what you’re looking for. It’s an increasingly popular test in recent years. VO2 max measures your aerobic capacity. It can give you a sense of your cardiovascular fitness, which can be helpful as a benchmark to try to improve, often via short, intense intervals. This test can also help determine your max heart rate and training zones based on that. Lactate threshold or the point at which your body goes from aerobic to anaerobic is something you can train and improve. Knowing your threshold allows you to train in the proper zones so you can increase it. Wearable data is the most affordable option, and you can track a lot of these same things right from your watch like gate, cadence and stride length. But that data might not be very useful if you don’t know what to do with it. That’s where these tests come into play.

  • Trump Is Coming for Obamacare Again

    Trump Is Coming for Obamacare Again

    [ad_1]

    Donald Trump’s renewed pledge on social media and in campaign rallies to repeal and replace the Affordable Care Act has put him on a collision course with a widening circle of Republican constituencies directly benefiting from the law.

    In 2017, when Trump and congressional Republicans tried and failed to repeal the ACA, also known as Obamacare, they faced the core contradiction that many of the law’s principal beneficiaries were people and institutions that favored the GOP. That list included lower-middle-income workers without college degrees, older adults in the final years before retirement, and rural communities.

    In the years since then, the number of people in each of those groups relying on the ACA has grown. More than 40 million Americans now receive health coverage through the law, about 50 percent more than the roughly 27 million the ACA covered during the repeal fight in 2017. In the intervening years, nine more states, most of them reliably Republican, have accepted the law’s federal funding to expand access to Medicaid for low-income working adults.

    “Republicans came very close to repealing and replacing the ACA in 2017, but that may have been their best window before the law had fully taken hold and so many people have benefited from it,” Larry Levitt, the executive vice president for health policy at KFF, a nonpartisan think tank that studies health-care issues, told me. “I think it gets harder and harder to repeal as more people benefit.”

    Trump’s repeated declarations over the past several weeks that he intends to finally repeal the ACA if reelected surprised many Republicans. Few GOP leaders have talked about uprooting the law since the party’s last effort failed, during Trump’s first year as president. At that point, Republicans controlled both chambers of Congress. But whereas the House, with Trump’s enthusiastic support, narrowly voted to rescind the law, the Senate narrowly rejected repeal. Three GOP senators blocked the repeal effort by voting no—including the late Senator John McCain, who dramatically doomed the proposal by signaling thumbs-down on the Senate floor. (Trump mocked McCain while calling the ACA “a catastrophe” as he campaigned in Iowa last weekend.)

    Republicans lost any further opportunity to repeal the law in the 2018 election when Democrats regained control of the House of Representatives. With the legislative route blocked, Trump instead pursued an array of regulatory and legal efforts to weaken the ACA during his final years in office. But since the 2017 vote, the GOP has never again held the unified control of the White House, the House, and the Senate required to launch a serious legislative repeal effort.

    If Republicans did win unified control of Congress and the White House next November, most health-care experts I spoke with agreed that Trump would follow through on his promises to again target the ACA. Leslie Dach, the founder of Protect Our Care, a liberal group that supports the law, says that he takes Trump’s pledge to pursue repeal seriously, “because he is still trying to overturn the legacy of John McCain, and it’s one of the few things he lost. He doesn’t like to be a loser.”

    Trump hasn’t specified his plan to replace the ACA. But whatever alternative Trump develops will inevitably face one of the main problems that confounded Republicans’ last attempt at repeal: Every plan they put forward raised costs and diminished access to care for core groups in their electoral coalition.

    That was apparent in the contrast between how the ACA and the GOP alternatives treated the individual insurance market. The ACA created exchanges where the uninsured could buy coverage, provided them with subsidies to help them afford it, and changed the rules about what kind of policies insurers could sell them. Key among those changes were provisions that barred insurers from denying coverage to people with preexisting health conditions, required them to offer a broad package of essential health benefits in all policies, and prevented them from charging older consumers more than three times the premiums of younger people.

    The common effect of all these and many other requirements was to require greater risk sharing in the insurance markets. The ACA made coverage in the individual insurance market more available and affordable for older and sicker consumers partly by requiring younger and healthier consumers to purchase more expensive and comprehensive plans than they might have bought before the law went into effect. That shift generated complaints from relatively younger and healthier consumers in the ACA’s early years as their premiums increased.

    Every alternative that Republicans proposed during the Trump years sought to lower premiums by unraveling the ACA provisions that required more sharing of risks and costs. For instance, the House GOP plan allowed insurers to charge seniors five times as much as young people, reduced the number of guaranteed essential benefits, and allowed states to exempt insurers from the requirement to cover all applicants with preexisting health conditions.

    One problem the GOP faced was that although this approach might have lowered premiums for the young and healthy (albeit while leaving them with less comprehensive coverage), it would have significantly raised costs and reduced access for the old or sick. “A lot of ‘repeal and replace’ was putting more cost back on people with health-care problems,” Linda Blumberg, an institute fellow at the Urban Institute’s Health Policy Center, told me. The Rand Corporation calculated that for individuals with modest incomes, the House GOP plan would have cut premiums for the majority of those under age 45 while raising them for virtually everyone older than 45. The Congressional Budget Office, in its assessment of the House-passed GOP bill, projected that it would nearly double the number of people without health insurance by 2026, and that the greatest coverage losses would happen “among older people with lower income.”

    As I wrote in 2017, the paradox was that the Republican plans would have hurt older working-age adults—a preponderantly GOP-leaning constituency—while lowering costs for younger generations that mostly vote Democratic. I called this inversion the “Trumpcare conundrum.”

    The congressional Republican alternatives to the ACA under Trump also uniformly made deep cuts to Medicaid, the joint state-federal health-care program for low-income people. But GOP constituencies were big winners as well in the ACA provisions that expanded eligibility for Medicaid.

    Until the ACA, Medicaid was generally available only to adults earning less than the federal poverty level. But the law provided states with generous federal financing to expand coverage to low-income individuals earning up to 138 percent of the poverty level. Particularly in interior states, research showed that many of those low-income workers covered under the Medicaid expansion were white people without a college degree, the cornerstone of the modern Republican electoral coalition.

    Another big beneficiary from the Medicaid expansion was rural communities, which have become more reliably Republican in the Trump years. Expanding access to Medicaid was especially important to rural places because studies have consistently found that more people in those areas than in metropolitan centers suffer from chronic health problems, while fewer obtain health insurance from their employer, and more lack insurance altogether.

    The increased number of people covered under Medicaid gave rural hospitals a lifeline by reducing the amount of uncompensated care they needed to provide for patients lacking insurance. “When you go out to the rural areas, frankly most hospital executives, like other business people, they tend to be pretty conservative,” Timothy McBride, a co-director of the Center for Advancing Health Services, Policy & Economics Research at Washington University in St. Louis, told me. “And they don’t like government intervention. But I would go to see these people and they would say, ‘I’m for Medicaid expansion,’ because they had to deal with the uninsured.”

    The Medicaid expansion also quickly became a crucial source of financing for addiction treatment in states ravaged through the 2010s by the opioid epidemic. Before the ACA, addiction treatment programs relied on “a little bit of block grant money here, a local voucher there, kind of out-of-pocket payments, and a little bit of spit and glue,” Brendan Saloner, a professor at the Johns Hopkins Bloomberg School of Public Health who studies addiction, told me. “Then Medicaid came along, and it provided a much more reliable and stable source of payment.”

    Since the 2017 legislative battle, the ACA’s impact on all these fronts has only deepened. Biden and congressional Democrats both increased the federal subsidies to buy insurance on the Obamacare exchanges and expanded eligibility to families further into the middle class. Largely as a result, the number of people obtaining insurance through the exchanges soared from about 10 million then to more than 15 million as of this past December.

    Similarly, a majority of the 31 states that had expanded Medicaid by 2017 were solidly Democratic-leaning. But the nine additional states that have broadened eligibility since then include seven that voted for Trump in 2016 and 2020.

    That has not only increased the total number of low-income workers covered through the Medicaid expansion (from about 16 million then to well over 24 million now), but also broadened the red-state constituency for the ACA. McBride estimates that the federal government has annually pumped $2 billion into the health-care system in Missouri alone since voters there approved a Medicaid expansion in 2020. The federal Department of Health and Human Services recently calculated that the likelihood of rural hospitals closing was more than twice as high in the states that have refused to expand Medicaid than in those that have. Simultaneously, the amount of funding that Medicaid provides for the treatment of substance abuse has at least doubled since 2014, allowing it to serve nearly 5 million people, according to calculations by Tami Mark, a distinguished fellow in behavioral health at RTI International, a nonprofit independent research institute.

    Even more fundamentally, Blumberg argues, the pandemic showed the ACA’s value as a safety net. Through either the exchanges or Medicaid, the law provided coverage to millions who lost their job, and insurance, during the crisis. “This law was critical in protecting us from unforeseen circumstances even beyond the value that people had seen in 2017,” she told me. “If we had not had that in place, we would have seen massive amounts of uninsurance and people who could not have accessed vaccines and could not have accessed medical care when they became sick.”

    For all of these reasons and more, Douglas Holtz-Eakin, the president of the American Action Forum, a conservative think tank, told me that he believes it’s a mistake for Trump and the GOP to seek repeal once again. Holtz-Eakin, a former director of the Congressional Budget Office, remains critical of the ACA, which he says has not done enough to improve the quality of coverage or control costs.

    But, he points out, during the Trump years, Republicans succeeded in repealing some of the law’s elements that they disliked most, including the tax penalty on uninsured people who did not buy coverage. “I don’t think we should be happy with the current system,” Holtz-Eakin told me. “But it’s not fruitful to try to roll the clock back to 2010.”

    Beyond the policy challenges of excising the ACA from the health-care system, the political landscape also appears less hospitable to a renewed repeal drive. In 2017, KFF polling found that the share of Americans who viewed the law favorably only slightly exceeded the share dubious of it; in the group’s most recent survey measuring attitudes toward the law, more than three-fifths of Americans expressed favorable views, while only slightly more than one-third viewed it negatively. Support for individual provisions in the law, such as the ban on denying coverage because of preexisting conditions or the requirement that insurers allow kids to stay on their parents’ plans through age 26, runs even higher in polls.

    Yet even with all these obstacles, Trump’s promise to seek repeal again virtually ensures another round of the ACA war next year if Republicans win unified control of the federal government. By historical standards, that’s a remarkable, even unprecedented, prospect. Though Barry Goldwater, the 1964 GOP nominee, had opposed the creation of Medicare, for instance, no Republican presidential nominee ever proposed to repeal it after Lyndon B. Johnson signed it into law in 1965.

    If Trump wins the nomination, by contrast, it would mark the fourth consecutive time the GOP nominee has run on ending the ACA. (Among Trump’s main competitors, Florida Governor Ron DeSantis has also promised to produce an alternative to the ACA, and Nikki Haley, who has spoken less definitively on the topic, might feel irresistible pressure to embrace repeal too.) Congressional Republicans may have been surprised that Trump committed them to charging up that hill again, but that doesn’t mean they would refuse his command to do so. “He wants to reverse a loss and take it off the books,” Dach told me. “And we’ve learned that that party follows him. It’s not like they are going to stand up against him, especially in the House. They will destroy the law if they can.”

  • ‘Window Into History’: Tapes Detail LBJ’s Stolen Election

    ‘Window Into History’: Tapes Detail LBJ’s Stolen Election

    [ad_1]

    DALLAS (AP) — The story was a blockbuster: A former Texas voting official was on the record detailing how nearly three decades earlier, votes were falsified to give then-congressman Lyndon B. Johnson a win that propelled the future president into the U.S. Senate.

    The audio recordings from Associated Press reporter James W. Mangan’s interviews for the 1977 story were posted this week on the LBJ Presidential Library and Museum’s archival website, Discover LBJ. After Mangan’s death in 2015 at the age of 87, his family found the labeled cassette tapes at his San Antonio home and donated them last summer to the library on the campus of the University at Texas at Austin.

    Luis Salas, the former South Texas election judge, told Mangan for the story: “Johnson did not win that election; It was stolen for him. And I know exactly how it was done.”

    The story, which made front pages across the country, pulled back the curtain on the razor-thin victory that had drawn suspicions ever since election officials in rural Jim Wells County announced the discovery of uncounted votes in a ballot box known as Box 13 in the days after the 1948 Democratic primary Senate runoff. And now, at a time when election fraud is rare but former President Donald Trump and his allies amplify baseless allegations blaming it for his 2020 loss, the tapes and story show what compelling evidence of actual fraud looks like.

    Mangan’s son, Peter, said listening the tapes was like getting “a little window into history.”

    On one cassette, he said, it sounds like his father is in his car, reciting what he’d just been told.

    “You can hear cars going by and he’s kind of, you can tell he’s a little excited, because I think he finally got the goods,” Peter Mangan said.

    Mark Lawrence, the library’s director, said the recordings are “deeply connected to one of the big mysteries and controversies that’s hung around LBJ for decades.” In a 1984 oral history that Salas gave to the library, he said one of the reasons he finally decided to talk was because he had been quite ill.

    Mangan said in a 2008 AP story that as he worked to convince Salas to go on the record, he told him: “If you die, history will never know what happened.”

    Lawrence said much is now known about Box 13, thanks to both Mangan’s 1977 story and research done later by LBJ biographer Robert Caro, who “essentially reaffirmed” Mangan’s story and built on it.

    “The kinds of irregularities we can see were at work in the 1948 Senate race in Texas were, I think it’s fair to say, pretty widespread across American history and all regions of the country to one extent or another but certainly in the South and along the Mexican borderlands, as recently as the 1940s,” Lawrence said.

    Salas told Mangan that the powerful South Texas political boss George B. Parr — who wielded control with favors and coercion — ordered that some 200 votes be added to Box 13. Salas said he then watched as the fraudulent votes were added in alphabetical order, with the names coming from people who hadn’t voted in the election.

    The new votes gave Johnson the primary victory over then-Gov. Coke Stevenson by an 87-vote margin. Johnson — subsequently bestowed with the nickname “Landslide Lyndon” — went on to easily defeat the Republican in the general election, long before the GOP became the dominant force in Texas politics.

    Johnson, elected to the U.S. House in 1937, had run for U.S. Senate in 1941 and lost to then-Gov. Wilbert Lee “Pappy” O’Daniel in an election widely accepted by historians to have been corrupt, Lawrence said.

    “The standard story that gets told, and I think there’s an awful lot to it, is that when LBJ’s second chance comes along in 1948, he’s determined not to have the election stolen from him again,” Lawrence said.

    Lawrence said the 1948 Senate victory “catapults” Johnson to national attention. Johnson became then-President John F. Kennedy’s vice president and was sworn in as president Nov. 22, 1963, after Kennedy was assassinated in Dallas. Johnson was elected president in 1964. He decided not to run again in 1968 and died of a heart attack in 1973 at the age of 64.

    Lawrence said that while the Box 13 incident shows that “LBJ was willing to do what he had to do to maintain political power,” he was also a man who, “when he had the opportunity, he was more inclined to act on principle.” Lawrence noted Johnson’s efforts to “ensure that people were able to vote in fair and equitable elections.”

    In 1965, Johnson signed the Voting Rights Act, which outlawed practices designed to disenfranchise Black voters by banning literary tests and poll taxes. The act also gave the federal government the authority to take over voter registration in counties with a pattern of persistent racial discrimination, although that is no longer the case after the U.S. Supreme Court struck down the requirement in 2013.

    James Mangan retired from AP on Jan. 1, 1989, after a 36-year career with the company that took him to cities across the U.S. and to Europe. With each move, Peter Mangan said, his father held on to the Box 13 tapes.

    “He always kept these,” he said, “so I know they must have been important to him.”

  • Set Your Clocks Back Tonight—And No, Daylight Saving Time Isn’t Going Away Yet

    Set Your Clocks Back Tonight—And No, Daylight Saving Time Isn’t Going Away Yet

    [ad_1]

    Topline

    Americans will set their clocks back Sunday morning as daylight saving time comes to an end—even as a national debate gains steam over whether the longstanding tradition of switching between daylight saving and standard time should be eliminated, and if daylight should be permanently pushed back the extra hour.

    Key Facts

    At 2 a.m. Sunday, clocks in the U.S. will revert to standard time, turning back one hour and giving Americans an extra hour of sleep that night, but shifting sunrise and sunset an hour earlier and ushering in four-plus months of darker winter evenings.

    In March, the Senate approved the bipartisan Sunshine Protection Act, which would make daylight saving time permanent, extending daylight longer into the evening between November and March in exchange for darker winter mornings—but the bill has stalled in the House.

    The bill, which would apply to every state except Hawaii and Arizona—an outlier in the daylight savings arena, observing year-round standard time—is the latest attempt at longer evenings, with proponents, including Sen. Marco Rubio (R-Fla.), who introduced the bill, arguing it would reduce crime, improve rush-hour traffic safety and encourage kids to play outside longer.

    Critics of the semi-annual switch also point out the process of changing the clocks twice a year has been linked to increases in traffic accidents, robberies, workplace injuries and heart attacks in the days that follow the shift—a 2004 study published in Accident, Analysis and Prevention also found permanent daylight saving would decrease vehicle deaths by more than 350 per year.

    Lawmakers in Arkansas, Arizona, California, Colorado, Delaware, Florida, Illinois, Louisiana, Maine, New Jersey, Oregon, South Carolina, Tennessee, Utah and Washington have proposed bills to make daylight saving time permanent, although none of those bills have received Congressional approval—the Uniform Time Act allows states to exempt themselves from daylight saving time—which Arizona did (with the exception of the Navajo Nation) in 1968—but forbids states from remaining on permanent daylight saving time without congressional approval.

    Chief Critic

    Scientists studying sleep warn a transition to permanent daylight saving time could disrupt Americans’ circadian rhythms as midday sunlight is pushed back from noon to 1 p.m. The result, according to a 2019 study in the Journal of Health Economics, is that people’s “social and biological time” drift apart, creating a phenomenon known as “social jetlag,” while overall sleep time decreases by an average of 19 minutes, and impairs sleep quality. According to University of Massachusetts Chan Medical School-Baystate professor Karin Johnson, that could increase the risk of health problems, including obesity, diabetes and heart disease, NBC News reported.

    Big Number

    63%. That’s the share of U.S. adults surveyed in an American Academy of Sleep Medicine survey last July that want to eliminate seasonal time changes, including 38% who strongly support eliminating it.

    Key Background

    Although the debate over daylight saving time is almost as old as the practice itself, it’s facing renewed criticism as lawmakers attempt to do away with standard time altogether. The semi-annual changing of the clocks began in 1918 as an initiative to save fuel, give shoppers extra time after work, although federal officials left it up to state and local lawmakers to decide when they should reset their clocks, and whether they do it at all—creating a completely nonuniform nationwide time system. Congress standardized the practice in 1966, with former President Lyndon B. Johnson approving the Uniform Time Act, following through on three years of planning from the Committee for Time Uniformity. In 1996, Congress amended the Uniform Time Act, extending daylight saving time by bringing the start date up nearly one month, from the first Sunday in April to the second Sunday in March while pushing the end date from the last Sunday in October to the first Sunday in November. Recently, however, a bipartisan group of lawmakers are once again trying to change America’s time. In a statement last year, Sen. Ed Markey (D-Mass.), who supports the Sunshine Protection Act, argued permanent daylight saving time “positively impacts consumer spending and shifts energy consumption,” while Sen. James Lankford (R-Okla.) said “I don’t know a parent of a young child that would oppose getting rid of springing forward or falling back.”

  • White House is pushing ahead research to cool Earth by reflecting back sunlight

    White House is pushing ahead research to cool Earth by reflecting back sunlight

    [ad_1]

    The White House is coordinating a five-year research plan to study ways of modifying the amount of sunlight that reaches the earth to temper the effects of global warming, a process sometimes called solar geoengineering or sunlight reflection.

    The research plan will assess climate interventions, including spraying aerosols into the stratosphere to reflect sunlight back into space, and should include goals for research, what’s necessary to analyze the atmosphere, and what impact these kinds of climate interventions may have on Earth, according to the White House‘s Office of Science and Technology Policy. Congress directed the research plan be produced in its spending plan for 2022, which President Joe Biden signed in March.

    Some of the techniques, such as spraying sulfur dioxide into the atmosphere, are known to have harmful effects on the environment and human health. But scientists and climate leaders who are concerned that humanity will overshoot its emissions targets say research is important to figure out how best to balance these risks against a possibly catastrophic rise in the Earth’s temperature.

    Getting ready to research a topic is a very preliminary step, but it’s notable the White House is formally engaging with what has largely been seen as the stuff of dystopian fantasy. In Kim Stanley Robinson’s science fiction novel, “The Ministry for the Future,” a heat wave in India kills 20 million people and out of desperation, India decides to implement its own strategy of limiting the sunlight that gets to Earth.

    Chris Sacca, the founder of climate tech investment fund Lowercarbon Capital, said it’s prudent for the White House to be spearheading the research effort.

    “Sunlight reflection has the potential to safeguard the livelihoods of billions of people, and it’s a sign of the White House’s leadership that they’re advancing the research so that any future decisions can be rooted in science not geopolitical brinkmanship,” Sacca told CNBC. (Sacca has donated money to support research in the area, but said he has “zero financial interests beyond philanthropy” in the idea and does not think there should be private business models in the space, he told CNBC.)

    Harvard professor David Keith, who first worked on the topic in 1989, said it’s being taken much more seriously now. He points to formal statements of support for researching sunlight reflection from the Environmental Defense Fund, the Union of Concerned Scientists, and the Natural Resources Defense Council, and the creation of a new group he advises called the Climate Overshoot Commission, an international group of scientists and lawmakers that’s evaluating climate interventions in preparation for a world that warms beyond what the Paris Climate Accord recommended.

    To be clear, nobody is saying sunlight-reflection modification is the solution to climate change. Reducing emissions remains the priority.

    “You cannot judge what the country does on solar-radiation modification without looking at what it is doing in emission reductions, because the priority is emission reductions,” said Janos Pasztor, executive director of the Carnegie Climate Governance Initiative. “Solar-radiation modification will never be a solution to the climate crisis.”

    Three ways to reduce sunlight

    The idea of sunlight reflection first appeared prominently in a 1965 report to President Lyndon B. Johnson, entitled “Restoring the Quality of Our Environment,” Keith told CNBC. The report floated the idea of spreading particles over the ocean at a cost of $100 per square mile. A one percent change in the reflectivity of the Earth would cost $500 million per year, which does “not seem excessive,” the report said, “considering the extraordinary economic and human importance of climate.”

    The estimated price tag has gone up since then. The current estimate is that it would cost $10 billion per year to run a program that cools the Earth by 1 degree Celsius, said Edward A. Parson, a professor of environmental law at UCLA’s law school. But that figure is seen to be remarkably cheap compared to other climate change mitigation initiatives.

    A landmark report released in March 2021 from the National Academies of Sciences, Engineering, and Medicine addressed three kinds of solar geoengineering: stratospheric aerosol injection, marine cloud brightening, and cirrus cloud thinning.

    Stratospheric aerosol injection would involve flying aircraft into the stratosphere, or between 10 miles and 30 miles skyward, and spraying a fine mist that would hang in the air, reflecting some of the sun’s radiation back into space.

    “The stratosphere is calm, and things stay up there for a long time,” Parson told CNBC. “The atmospheric life of stuff that’s injected in the stratosphere is between six months and two years.”

    Stratospheric aerosol injection “would immediately take the high end off hot extremes,” Parson said. And also it would “pretty much immediately” slow extreme precipitation events, he said.

    “The top-line slogan about stratospheric aerosol injection, which I wrote in a paper more than 10 years ago — but it’s still apt — is fast, cheap and imperfect. Fast is crucial. Nothing else that we do for climate change is fast. Cheap, it’s so cheap,” Parson told CNBC.

    “And it’s not imperfect because we haven’t got it right yet. It’s imperfect because the imperfection is embedded in the way it works. The same reason it’s fast is the reason that it’s imperfect, and there’s no way to get around that.”

    One option for an aerosol is sulfur dioxide, the cooling effects of which are well known from volcanic eruptions. The 1991 eruption of Mount Pinatubo, for instance, spewed thousands of tons of sulfur dioxide into the stratosphere, causing global temperatures to drop temporarily by about 1 degree Fahrenheit, according to the U.S. Geological Survey.

    A giant volcanic mushroom cloud explodes some 20 kilometers high from Mount Pinatubo above almost deserted US Clark Air Base, on June 12, 1991 followed by another more powerful explosion. The eruption of Mount Pinatubo on June 15, 1991 was the second largest volcanic eruption of the twentieth century.

    There’s also a precedent in factories that burn fossil fuels, especially coal. Coal has some sulfur that oxidizes when burned, creating sulfur dioxide. That sulfur dioxide goes through other chemical reactions and eventually falls to the earth as sulfuric acid in rain. But during the time that the sulfur pollution sits in the air, it does serve as a kind of insulation from the heat of the sun.

    Ironically, as the world reduces coal burning to curb the carbon dioxide emissions that cause global warming, we’ll also be eliminating the sulfur dioxide emissions that mask some of that warming.

    “Sulfur pollution that’s coming out of smokestacks right now is masking between a third and a half of the heating signal from the greenhouse gases humans have already emitted into the atmosphere,” Parson said.

    In other words, we’ve been doing one form of sunlight reflection for decades already, but in an uncontrolled fashion, explained Kelly Wanser, the executive director of SilverLining, an organization promoting research and governance of climate interventions.

    “This isn’t something totally new and Frankenstein — we’re already doing it; we’re doing it in the most dirty, unplanned way you could possibly do it, and we don’t understand what we’re doing,” Wanser told CNBC. 

    Spraying sulfur in the stratosphere is not the only way of manipulating the amount of sunlight that gets to the Earth, and some say it’s not the best option.

    “Sulfur dioxide is likely not the best aerosol and is by no means the only technique for this. Cloud brightening is a very promising technique as well, for example,” Sacca told CNBC.

    Marine cloud brightening involves increasing the reflectivity of clouds that are relatively close to the surface of the ocean with techniques like spraying sea salt crystals into the air. Marine cloud brightening generally gets less attention than stratospheric aerosol injection because it affects a half dozen to a few dozen miles and would potentially only last hours to days, Parson told CNBC.

    Cirrus cloud thinning, the third category addressed in the 2021 report from the National Academies, involves thinning mid-level clouds, between 3.7 and 8.1 miles high, to allow heat to escape from the Earth’s surface. It is not technically part of the “solar geoengineering” umbrella category because it does not involve reflecting sunlight, but instead involves increasing the release of thermal radiation.

    Known risks to people and the environment

    There are significant and well-known risks to some of these techniques — sulfur dioxide aerosol injection, in particular.

    First, spraying sulfur into the atmosphere will “mess with the ozone chemistry in a way that might delay the recovery of the ozone layer,” Parson told CNBC.

    The Montreal Protocol adopted in 1987 regulates and phases out the use of ozone depleting substances, such as hydrochlorofluorocarbons (HCFCs) which were commonly used in refrigeration and air conditioners, but that healing process is still going on.

    Also, sulfates injected into the atmosphere eventually come down as acid rain, which affects soil, water reservoirs, and local ecosystems.

    Third, the sulfur in the atmosphere forms very fine particulates that can cause respiratory illness.

    The question, then, is whether these known effects are more or less harmful than the warming they would offset.

    “Yes, damaging the ozone is bad, acid deposition is bad, respiratory illness is bad, absolutely. And spraying sulfur in the stratosphere would contribute in the bad direction to all of those effects,” Parson told CNBC. “But you also have to ask, how much and relative to what?”

    The sulfur already being emitted from the burning of fossil fuels is causing environmental damage and is already killing between 10 million to 20 million people a year due to respiratory illness, said Parson. “So that’s the way we live already,” he said.

    Meanwhile, “the world is getting hotter, and there will be catastrophic impacts for many people in the world,” said Pasztor.

    “There’s already too much carbon out there. And even if you stop all emissions today, the global temperature will still be high and will remain high for hundreds of years. So, that’s why scientists are saying maybe we need something else, in addition — not instead of — but maybe in addition to everything else that is being done,” he said. “The current action/nonaction of countries collectively — we are committing millions of people to death. That’s what we’re doing.”

    For sunlight-reflection technology to become a tool in the climate change mitigation toolbox, awareness among the public and lawmakers has to grow slowly and steadily, according to Tyler Felgenhauer, a researcher at Duke University who studies public policy and risk.

    “If it is to rise on to the agenda, it’ll be kind of an evolutionary development where more and more environmental groups are willing to state publicly that they’re for research,” Felgenhauer told CNBC. “We’re arguing it’s not going to be some sort of one big, bad climate event that makes us all suddenly adopt or be open to solar geoengineering — there will be more of a gradual process.”

    Research it now or be caught off guard later?

    Some environmentalists consider sunlight relfection a “moral hazard,” because it offers a relatively easy and inexpensive alternative to doing the work of reducing emissions.

    One experiment to study stratospheric aerosols by the Keutsch Group at Harvard was called off in 2021 due to opposition. The experiment would “threaten the reputation and credibility of the climate leadership Sweden wants and must pursue as the only way to deal effectively with the climate crisis: powerful measures for a rapid and just transition to zero emission societies, 100% renewable energy and shutdown of the fossil fuel industry,” an open letter from opponents said.

    But proponents insist that researching sunlight-modification technologies should not preclude emissions-reduction work.

    “Even the people like me who think it’s very important to do research on these things and to develop the capabilities all agree that the urgent top priority for managing climate change is cutting emissions,” Parson told CNBC.

    Keith of Harvard agreed, saying that “we learn more and develop better mechanism[s] for governance.”

    Doing research is also important because many onlookers expect that some country, facing an unprecedented climate disaster, will act unilaterally to will try some version of sunlight modification anyway — even if it hasn’t been carefully studied.

    “In my opinion, it’s more than 90 percent likely that within the next 20 years, some major nation wants to do this,” Parson said.

    Sacca put the odds even higher.

    “The odds are 100 percent that some country pursues sunlight reflection, particularly in the wake of seeing millions of their citizens die from extreme weather,” Sacca told CNBC. “The world will not stand idly by and leaders will feel compelled to take action. Our only hope is that by doing the research now, and in public, the world can collaboratively understand the upsides and best methods for any future project.”  

    Correction: The Climate Overshoot Commission has not issued a formal statement of support for sunlight reflection.
