    Showers exit DC area ahead of Fourth of July fireworks – WTOP News

    [ad_1]

    Showers and storms appear to be moving out of the D.C. region this hot and humid Fourth of July after soaking rain impacted some outdoor celebrations.

    Listen to WTOP on the 8s for the latest on traffic and weather conditions.

    A few lingering showers are wrapping up on this hot and humid Fourth of July after soaking rain and storms dampened some outdoor celebrations in the D.C. area earlier Thursday evening. Here’s what you need to know.

    People dressed in patriotic outfits huddled under umbrellas on the National Mall as rain plummeted on the crowd earlier Thursday evening.

    Any isolated showers and thunderstorms are expected to fall apart by sunset in time for the firework displays, according to 7News First Alert meteorologist Jordan Evans. Thousands of people are expected to gather on the mall to watch fireworks extravaganza in the nation’s capital.

    After a short break in the wet weather, a couple of storms could form once again overnight.

    The weather has cooled off and an earlier heat advisory across the region expired at 8 p.m. Temperatures are expected to be in the 70s overnight.

    Showers, storms disrupt July Fourth festivities

    The forecast prompted temporary adjustments ahead of “A Capitol Fourth,” according to a social media post from the U.S. Capitol Police. Police closed the entrance to the event for more than an hour Thursday. With the thunderstorms dissipating, police reopened the entrance and the concert is expected to start on time at 8 p.m. on CBS.

    The Fourth of July in the District concert on Pennsylvania Avenue was paused due to the wet weather. Mayor Muriel Bowser said in a social media post the rain has stopped and concert will go on.



    Those disruptions came after National Weather Service had forecast that some of the storms Thursday could produce strong, gusty winds, lightning and heavy rain.

    Poor air quality ahead of fireworks

    Earlier in the day, there was poor air quality in some areas. Northern Virginia and D.C. were under a Code Orange air quality alert, according to The Metropolitan Washington Council of Governments, while Maryland was only facing moderate air quality.

    “It’s Code Orange, which is unhealthy for sensitive groups,” said 7News First Alert Chief Meteorologist Veronica Johnson. “If you suffer from lung or heart issues, limit your time outdoors for today.”

    The Metropolitan Washington Council of Governments said those sensitive groups also include the elderly, people with asthma, pregnant people and children.

    The poor air quality is due to particle pollutions, which the nonprofit Clean Air Partners said often occurs when fireworks meet hot weather.

    D.C.’s Department of Energy and Environment said that temporary air pollution levels spike around Independence Day and recommend that sensitive groups limit their time outside before and during fireworks shows. The department also recommends wearing an N95 or K-N95 mask to limit exposure to pollution.

    Looking ahead — Friday’s weather

    A hot and humid pattern is expected to continue throughout the weekend, with a chance of storms revisiting the D.C. area.

    “We are gonna be hot and humid Friday and Saturday with afternoon rain chances,” Whelan said. “Dry on Sunday with highs in the low 90s.”

    There will be another heat advisory on Friday with highs in the mid- to upper 90s and feels-like temperatures as high as 109, according to the National Weather Service.

    Current weather:

    Forecast:

    FOURTH OF JULY
    Partly cloudy
    Risk of showers, storms
    Highs: 90-95
    Heat Index: near 100-105
    Winds: Southwest 5-10 mph
    If thunder roars, head indoors. Fortunately, most of the rain and storm activity should be over by the time the fireworks go off in the 9 p.m. hour.

    Thursday NIGHT
    Mostly cloudy
    Lows: 75-80
    Winds: Southwest 5 mph
    It will be a warm and muggy night with lows in the 70s.

    FRIDAY
    HEAT ALERT
    Partly sunny
    PM storms
    Highs: 93-97
    Heat Index: 100-105
    Winds: Southwest 5-10 mph
    Plan for an even hotter and more humid day to round out the week. High temperatures will soar into the mid-90s, but with the humidity, feels-like temperatures will near 105 degrees. Additional chance for showers and storms are possible during the afternoon and early evening hours.

    SATURDAY
    Partly sunny
    Highs: 92-96
    Winds: Southwest 5-10 mph
    It will be another very hot and very humid day with feels like temperatures nearing 105 during the afternoon. An isolated shower or storm is possible.

    SUNDAY
    Partly to mostly sunny
    Highs: 90-95
    Winds: Northwest 5-10 mph
    A drop in humidity is expected to round out the weekend, which will be a welcome change. It will still be hot with afternoon highs in the low to mid 90s.

  • Newburyport wins big in e-bus bonanza

    Newburyport wins big in e-bus bonanza

    [ad_1]

    Schools in North of Boston and southern New Hampshire communities, including Newburyport, are among the largest recipients of grants in the latest round of Clean School Bus Program awards.

    As part of its ongoing effort to replace diesel-fueled school buses, the Biden administration said this week it will provide about 530 school districts across nearly all states with an additional $1 billion to help them purchase clean school buses.

    Massachusetts school districts are in line for more than $42 million to purchase electric buses as part of an effort to upgrade the state’s aging fleet and reduce emissions from diesel-powered vehicles.

    Newburyport is receiving $3 million for 15 buses, according to the Biden administration.

    The Derry Cooperative School District in New Hampshire is receiving one of the largest grants in the region – $8.6 million for 25 electric school buses, thanks to an application submitted by First Student Inc., the transportation contractor for the district.

    Several North of Boston school districts are also sharing in the e-bus funding, according to a list provided by the White House. Andover is receiving $5 million for 25 e-buses, while Ipswich is getting $5 million for 15.

    Salem is receiving $2.6 million for 13 e-buses, the Biden administration said. Other school districts, including Gloucester, Marblehead, Beverly and the Essex North Shore Agricultural and Technical School, are also getting funding to buy new e-buses.

    In addition to Derry, eight other New Hampshire districts such as Concord and Nashua will receive some of the funding, according to the White House. The money comes from the latest disbursements of grants through the Clean School Bus Program administered by the U.S. Department of Environmental Protection.

    The rebates will help school districts purchase more than 3,400 clean school buses – 92% of them electric – to accelerate the nation’s transition to zero-emission vehicles and produce cleaner air in schools and communities, according to the Biden administration.

    EPA Administrator Michael S. Regan said in a conference call with reporters Tuesday that the funding will help “transform the nation’s school bus fleet to better protect our most precious cargo – our kids – saving school districts money, improving air quality, and bolstering American manufacturing all at the same time.”

    The federal program has awarded nearly $3 billion for 8,500 electric and alternative fuel buses in more than 1,000 school districts, according to the Biden administration.

    Low-income, rural and tribal communities – accounting for about 45% percent of the selected projects – are slated to receive roughly 67% of the total funding, per the administration.

    Regan noted how “low-income communities and communities of color have long felt the disproportionate impacts of air pollution leading to severe health outcomes that continue to impact these populations.”

    As for business and economic opportunities, Regan pointed to the development of well-paying manufacturing jobs and investment in local businesses stemming from the increasing demand for these clean school buses.

    “As more and more schools make the switch to electric buses, there will be a need for American-made batteries, charging stations and service providers to maintain the buses supercharging and reinvigorating local economies,” he added.

    The program was initially funded through the Bipartisan Infrastructure Law signed by Biden in November 2021, which includes $5 billion over five years to replace the country’s current school buses with “zero-emission and low-emission models.”

    In January, the EPA announced more than $1 billion in funding for 2,700 clean school buses in 280 school districts in 37 states, including Massachusetts.

    Federal health officials say exposure to diesel exhaust can lead to major health conditions such as asthma and respiratory illnesses, especially among children.

    Despite the Biden administration’s efforts, e-buses still make up a tiny percentage of the buses on the roads nationwide, according to the U.S. Department of Transportation.

    The number of e-buses grew by 112% between 2018 and 2021. But with just 1,300 on the roadways in 2021, that represented just 2% of the transit buses in operation, according to DOT data. Of about 500,000 school buses nationwide, only 1,800 were electric in 2021, the federal agency said.

    Expert discusses EPA crackdown on air quality rules


    Expert discusses EPA crackdown on air quality rules

    03:16

    Much of the U.S. Northeast was smothered last summer by dense smoke from Canadian wildfires, leading to New York City’s worst air quality since the 1960s. Such episodes, once mostly isolated incidents, are increasingly common due to the impact of climate change, new research shows. 

    About 83 million Americans, or 1 in 4, are already exposed each year to air quality that is categorized as “unhealthy” by the Air Quality Index (AQI), a number that could grow to 125 million people within decades, according to First Street Foundation, which analyzes climate risks. The unhealthy AQI level, color-coded red, means that outdoor activities can result in lung impairment for some people, including respiratory ailments like chest pain and coughs. 

    The nation’s worsening air quality comes after decades of improvements thanks to regulations such as the 1970 Clean Air Act, which tightened federal rules on pollutants emitted by factories and automobiles. But the recent rise in poor air quality could be harder to battle because it’s linked to global warming, with higher temperatures and drought causing more smoke-spewing wildfires, First Street said. 

    “Additional heart attacks”

    At the same time, the rise in poor air quality threatens to reverse the health benefits that followed stricter pollution regulations starting in the 1960s and to hurt the U.S. economy, said Jeremy Porter, head of climate implications research at First Street. 

    “We’re essentially adding back additional premature deaths, adding back additional heart attacks,” Porter told CBS MoneyWatch. “We’re losing productivity in the economic markets by additionally losing outdoor job work days.”

    Already, there’s some evidence that people are leaving parts of the country with lower air quality, contributing to what is effectively a redrawing of the nation’s map by wildfire, flood and other effects of climate change.

    “We’ve seen very early statistical signals in our own analysis that people are moving away from the smoke that comes from wildfire,” Porter said. “The downstream effect of people moving away is that property values start to suffer because the area becomes less desirable. And then as the area becomes less desirable, tax revenues are directly impacted because the property values are decreasing.”

    Residents of California, Oregon and Washington state are seeing the greatest decline in air quality, partially due to wildfires in those regions. In California, air quality today is often in the “purple” and “maroon” levels — considered very healthy to hazardous — something that was unheard of about 15 years ago, First Street’s analysis found. At the same time, the number of “green” days, considered healthy, have decreased by a third since 2010. 

    Yet the impact isn’t only being felt on the West Coast, First Street found. 

    “It’s become something that is impacting people’s daily lives east of the Mississippi River,” Porter noted. In 2022, fires in the Florida panhandle were “so bad that people were asked to evacuate from their neighborhoods, which is kind of unheard of.”

    The number of unhealthy AQI days is likely to grow in the coming decades due to climate change, First Street projected. Worst hit could be the Western states, but Eastern states aren’t immune. Pockets of the Southwest, especially on the Florida-Georgia border, are already seeing an increase in the number of days with unhealthy AQI numbers. 

    Particulate matter and ozone

    Poor air quality is linked to increases in particulate matter and ozone, which are rising due to changes in the environment including extreme heat, drought and wildfires. Particulate matter that’s less than 2.5 microns in diameter, also called PM2.5, is particularly concerning because these tiny flecks of pollution can get deep into your lungs, causing a range of health problems. 

    PM2.5 particulates are increasing because of wildfires, while 2022 research found that ground-level ozone is also being exacerbated by the increasingly devastating blazes. Ozone levels can inflame your airways and raise the risks of an asthma attack, among other health problems, according to the Environmental Protection Agency.

    Although reversing the amount air pollution linked to climate change is difficult, at least knowing the risks and how to mitigate them can help, Porter said. First Street has a site called RiskFactor.com where you can enter your address and see your risks for flooding, fire, wind and heat. 

    Individuals may also need to take steps to protect their health in the face of more poor air quality days, he added.

    “Being able to keep smoke out of your house is really important,” Porter said. “Things like making sure your windows are sealed, and something as simple as changing the filter on your HVAC can make a big, big impact on how clean the air is inside your house.”

  • Los Angeles smog woes worsen as U.S. EPA threatens to reject local pollution plan

    Los Angeles smog woes worsen as U.S. EPA threatens to reject local pollution plan

    [ad_1]

    The U.S. Environmental Protection Agency is preparing to reject California’s plan to curb air pollution in Los Angeles, a consequential move that could result in stiff economic sanctions and federal regulatory oversight of the nation’s smoggiest region.

    Despite having the strictest air pollution rules in the nation, Southern California has never complied with federal health standards for ozone, the lung-searing gas commonly called smog. Because of this, state and local air regulators are required to submit plans to the EPA detailing how they intend to reduce pollution and comply with federal standards.

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

    California air regulators acknowledge that the region still needs to reduce smog-forming nitrogen oxides by more than 100 tons per day in order to achieve the 1997 standard for ozone.

    However, the South Coast Air Quality Management District proposal calls on the federal government to make most of those cuts — at least 67 tons per day — arguing that some of the largest sources of smog-forming emissions are federally regulated, such as ships, trains and aircraft. Local air quality officials lack the jurisdiction to regulate mobile sources of emissions, and can only control stationary sources, such as industrial facilities.

    In a recent draft response, the EPA has proposed rejecting California’s plan, declaring “states do not have authority” under the Clean Air Act or the Constitution to order the federal government to reduce pollution.

    In a pointed response, local air officials claimed the EPA was responsible for the damaging health effects of Los Angeles area smog, because it has failed to offer solutions to curb emissions from “sources that they know are beyond our control.”

    “U.S. EPA’s draft decision is disheartening,” read a statement from the air district. “South Coast AQMD intends to comment on this new proposal and take all appropriate actions in hopes that this decision does not become final. More importantly, U.S. EPA will need to answer the millions of residents, especially children, who have asthma, lung disease and other illnesses associated with air pollution that continue to suffer.”

    The EPA has until July 1 to decide whether to finalize the rejection. If the state and local air regulators fail to submit a plan that the EPA finds acceptable within that time, the federal government could withhold billions of dollars in highway funding, place strict requirements on new permits and even impose a federal plan to curb smog.

    The EPA has disapproved of the air district’s plans several times in the past, but the region has managed to avert potential sanctions.

    The proposed denial is the latest confrontation between Southern California air regulators and the Biden EPA — two unlikely adversaries who have clashed for nearly two years over how to solve the region’s long-standing issues with smog.

    It has also highlighted the complex nature of regulating pollution in the region where at least three entities have authority — the local air district, which oversees smokestack emissions; the California Air Resources Board, which governs in-state vehicles; and the EPA, which handles interstate and international travel.

    However, some environmental advocates say the dilemma is a collective failure by every level of government.

    Adrian Martinez, a senior attorney with Earthjustice, said the conflict follows years of repeated delays and deadline extensions, when all three environmental agencies were capable of cutting more emissions.

    “The plan to meet our clean air standards relied on these faith-based assumptions that we’ll figure out how to reduce the pollution at a later time. And what ended up happening is we never figured it out,” Martinez said.

    Historically, Southern California has been plagued by smog, which forms when the region’s persistent sunlight interacts with vehicle exhaust and smokestack emissions. The region’s mountainous terrain confines this toxic haze over the region, rather than allowing it to disperse.

    Although there has been significant progress over the last several decades through the development of cleaner vehicle engines and pollution controls for industry, the region’s smog remains the worst in the country.

    Since 1997, nitrogen oxides have decreased 70% in the air basin. The majority of those emission reductions are the result of stricter vehicle standards imposed by the state, and locally imposed regulations on industry, according to the South Coast air district.

    As emission reductions have stalled and aircraft emissions have risen, the air district has found itself under increasing pressure to force the EPA’s hand. According to estimates, even if Southern California eliminates emissions from all building and industrial sources, it wouldn’t be enough to meet federal standards.

    The air district has sued the EPA for violating the Clean Air Act, arguing it was impossible for the region to comply with federal smog standards without massive cuts from federal sources. The move was intended to compel the EPA to adopt new regulatory strategies that would curtail pollution from ports, railyards and airports. The air district later settled the case.

    For its part, the Biden administration last year adopted tighter vehicle emission standards, including for heavy-duty trucks, which is expected to reduce smog.

    But these federal requirements still pale in comparison to rules in California — the only state that can implement its own vehicle emission standards with federal approval.

    “We acknowledge that there are sources of air pollution in South Coast that the air district and CARB do not have the regulatory authority to control,” an EPA spokesperson said in a statement. “EPA has made it a very high priority to help reduce mobile source emissions through rulemaking and leveraging unprecedented federal funding … wherever possible.”

    The EPA is accepting public comments on its proposed disapproval of the regional smog plan until March 4.

    If the EPA finalizes this disapproval, California will have 18 months to obtain the federal agency’s approval for a new plan. By failing to meet that deadline, the federal government would require some newly permitted businesses to reduce twice as many tons of smog-forming as they emit.

    Six months later, if the deadline still hasn’t been met, the Federal Highway Administration is required to impose a moratorium on highway funding (with exceptions for mass transit and public safety).

    No more than two years after final disapproval, the EPA must enforce a federal implementation plan to achieve federal smog standards.

    It’s the summer of changed climate. Get used to it | CNN Politics

    [ad_1]

    A version of this story appeared in CNN’s What Matters newsletter. To get it in your inbox, sign up for free here.



    CNN
     — 

    Here’s a hot take on the summer of 2023: The climate you grew up in is gone, replaced by something new and changing, but also inalterably different – where the Atlantic Ocean can reach hot-tub temperature, heat is a recurring public health concern and people will have to adapt their way of living.

    In this year of epic heat, it’s time to start thinking about how the climate changed rather than the fact of its changing.

    From a historical standpoint, we are in uncharted territory. This is not just the hottest month in human history. It may be the hottest month in 120,000 years, according to scientists in Europe.

    Nearly half the US is under a heat advisory this week, and the country’s largest power grid was on alert.

    The warnings that more fires, floods and storms would occur as the atmosphere heated up are here.

    A large portion of the country has seen smoke come and go from those Canadian wildfires. Tourists in Greece were forced to flee in the country’s largest-ever evacuation.

    Towns unused to flooding were under water this year in Vermont. Torrential rain flooded Boston’s Fenway park.

    The West Coast of the US, for instance, has gotten a respite so far from wildfires thanks to epic rainfall earlier in the year.

    But we can expect more heat more often. Asked by CNN’s Zain Asher about a heat index in Iran that approached 150 degrees Fahrenheit, Marina Romanello, executive director of the Lancet Countdown on Health and Climate Change, said to prepare for more.

    “What we know is the heat will become much more intense, much more frequent, and that if we don’t act urgently to reduce greenhouse gas emissions, then the outlook will be very serious with, as you said, temperatures that are beyond the limits of physiological survival.”

    Are we acting urgently? Asher pointed out California is phasing out gas-powered car sales. Romanello said the basic move would be to commit to phase out fossil fuels. But countries are not yet on that path or anywhere close to it.

    Take a look at Arizona, where Phoenix has endured nearly a full straight month of 110-plus-degree days.

    Cacti can’t stand the heat and are dying. Hospitals have been taxed. Doctors are treating people burned just by falling on the ground, according to one CNN report.

    The Phoenix area medical examiner has brought in extra refrigerated containers for bodies, like it did during spikes of Covid-19, to deal with potential overflow. Maricopa County has 25 heat-related deaths so far, but another 249 are under investigation.

    The urban density that creates economic opportunity also makes cities hotter than their surrounding areas. There can be variation up to 8 degrees between portions of a city with trees and green space and those that are mostly pavement.

    “These giant swings in temperature over short distances in cities, known as the urban heat island effect, make heat waves even worse,” writes CNN’s Rachel Ramirez of a new report by the nonprofit research group Climate Central. “Areas blanketed with asphalt, buildings, industry and freeways tend to absorb the sun’s energy then radiate more heat, while areas with abundant green space – parks, rivers, and tree-lined streets – radiate less heat and provide shade.”

    Ramirez notes that cities are looking for new ways to adapt, like painting roads white in Los Angeles, painting roofs in New York and more.

    Coral reefs off the Florida Keys, unable to stand the 100-plus-degree temperatures charted in some areas, are suffering a mass bleaching event, according to CNN’s Eric Zerkel, who writes experts were stunned at the two-week escalation that could kill some reefs off.

    That’s a very real and grim consequence. More theoretical is the possibility that the series of currents that circulates water around the oceans simply collapses.

    A study published in the journal Nature this week suggested the Atlantic Meridional Overturning Current, which includes the Gulf Stream, could collapse as early as 2025. Melting ice could dilute ocean water and alter the currents, which would affect everyone on the planet.

    The reason gas prices have spiked in recent days? On top of OPEC holding back supply, excessive heat is affecting productivity at oil refineries.

    In the US, while President Joe Biden has made pledges to make the US carbon neutral in the coming decades, he is not completely opposed to new oil projects. It was seen as a political win for him and West Virginia Sen. Joe Manchin, a Democrat, that the Supreme Court cleared the way Thursday for a new pipeline running through West Virginia.

    That news came the same day the White House announced new relief measures for people suffering from the record heat, including the creation of a new “heat hazard alert” system to clarify precautions for workers.

    “I don’t think anybody can deny the impact of climate change anymore,” Biden said, announcing the measures.

    A majority of Americans – 52% – said in Gallup survey in March, before this heat wave, that protecting the environment should be prioritized even if it hurts the economy. That’s compared with 43% who said the government should prioritize economic growth even if it hurts the environment.

    However.

    The numbers may fluctuate depending on how people feel about the health of the economy. But the share who prioritize economic growth over the environment has on the whole risen in Gallup’s polling over the long term. Between 1985 and 2002, that number never topped 40%. The partisan divide over climate change is also the largest it has ever been.

    The geophysicist Bill McGuire, a professor at University College London and author of “Hothouse Earth: An Inhabitant’s Guide,” writes for CNN Opinion this week that people’s vacations as we know them are over.

    He points to tourists who had to flee the island of Rhodes in Greece to get away from wildfires.

    “It would be a big mistake to regard these as freak events and to continue holidaying as usual in the years ahead,” McGuire writes. “On the contrary, the extreme weather conditions across southern Europe this summer are a wake-up call – a reminder that not even our vacations are insulated from the growing consequences of global heating.”

  • Smoke from hundreds of Canadian wildfires blankets northern US cities with air pollution | CNN

    Smoke from hundreds of Canadian wildfires blankets northern US cities with air pollution | CNN

    [ad_1]



    CNN
     — 

    Smoke from more than 1,000 wildfires burning across Canada has wafted over the northern US, bringing poor air quality and pollution that threaten residents’ health to northern US cities including Chicago, Illinois, and Minneapolis, Minnesota.

    Chicago, Minneapolis and Detroit, Michigan, are now among at least three major US cities that are ranked in the top 20 most polluted cities in the world, according to global pollution tracker IQAir.

    The smoke has drifted over the Great Lakes region, in particular, as about 1,090 active fires blaze throughout Canada, more than 670 of which are considered “out of control,” according to the Canadian Interagency Forest Fire Centre. That’s up from more than 880 fires there last week.

    The bulk of the country’s wildfires are burning in British Columbia, where more than 460 fires are ongoing, the agency reports.

    In the US, the National Weather Service (NWS) has issued air quality alerts for millions of people across Michigan and parts of Minnesota, Wisconsin, Illinois and Indiana.

    The blanket of hazy skies follows a belt of Canadian wildfire smoke which stretched across the US last week, triggering air quality alerts for more than a dozen states from Montana to Vermont, with some smoke reaching as far South as Alabama.

    The smoke is expected to shift eastward through the Great Lakes region through Tuesday and disperse by Wednesday – just as the upper Midwest is forecast to see some of its hottest temperatures so far this year. Minneapolis could reach 100° and Chicago will be in the upper 90s.

    The EPA in Illinois has declared an “Air Pollution Action Day” through Tuesday due to the “persistent” wildfire smoke causing elevated air pollution in the region. Similar advisories have been declares in Michigan and Wisconsin.

    The city is recommending that those with chronic respiratory issues limit their activities outdoors and is advising against strenuous activity for children, teens, seniors, people with heart or lung disease, and pregnant people.

    “All Chicagoans may also consider wearing masks, limiting their outdoor exposure, moving activities indoors, running air purifiers, and closing windows,” the city said in a release Monday.

    Wildfire smoke is packed with tiny pollutants – known as particulate matter – that can infiltrate the lungs and blood stream if inhaled. Particulate matter can commonly cause difficulty breathing and eye and throat irritation, but has also been linked to more serious long-term health issues such as lung cancer, according to the US Centers for Disease Control and Prevention.

    The US is likely to see the downwind effects of Canada’s prolonged wildfires as the country continues to experience its worst fire season on record.

    Almost 29 million acres of Canadian land have been scorched so far this year, according to the national fire center. Smoke from the blazes this summer have so far touched the American South and traveled across the Atlantic and into Europe.

    The crisis has elicited a flood of international support, as fire and emergency response personnel have deployed to the country from nations including the US, Australia and Brazil. At least two Canadian firefighters have died while battling the flames.

    Hard-hit British Columbia will receive federal assistance from the Canadian Armed Forces, Public Safety Canada announced last week.

    Hundreds of British Columbia’s fires have been ignited by lightning strikes from thunderstorms, according to the British Columbia Wildfire Service. Some of those thunderstorms were “dry,” producing insufficient amounts of rain to help quench any fires – a dangerous prospect in a province experiencing severe drought.

    As the human-driven climate crisis intensifies, scientists expect wildfire seasons will increase in severity, especially as droughts and heat become more common and more severe across the world.

  • Xi says China will follow its own carbon reduction path as US climate envoy Kerry meets top officials in Beijing | CNN

    Xi says China will follow its own carbon reduction path as US climate envoy Kerry meets top officials in Beijing | CNN

    [ad_1]



    CNN
     — 

    China will follow its own path to cut carbon emissions, leader Xi Jinping vowed Tuesday, as US climate envoy John Kerry called for faster action to confront the climate crisis in a high-profile visit to Beijing.

    Xi told a national conference on environmental protection that China’s commitment to its duel carbon goals – reaching a carbon peak by 2030 and carbon neutrality by 2060 – is “unwavering,” according to state news agency Xinhua.

    “But the path, method, pace and intensity to achieve this goal should and must be determined by ourselves, and will never be influenced by others,” he said.

    The comments came as Kerry met China’s Premier Li Qiang and top diplomat Wang Yi Tuesday, with Washington and Beijing – the world’s two largest polluters – resuming their long-stalled climate talks amid scorching heat waves across much of the globe.

    In the meeting with Li, Kerry stressed the “need for China to decarbonize the power sector, cut methane emissions, and reduce deforestation,” a spokesperson for the US State Department said in a statement.

    He also urged China to “take additional steps to enhance its climate ambition in order to avoid the worst impacts of the climate crisis.”

    China has invested heavily in clean energy in recent years. Its solar capacity is now greater than the rest of the world combined, and the country is also leading the world in wind capacity and electric vehicles.

    On the other hand, it has accelerated the approval of new coal plants due to a renewed focus on “energy security,” sparking concerns from environmentalists that these new projects will make the shift away from coal slower and more difficult.

    But Xi’s remarks at the conference suggest that China has no desire to be pushed, or be seen to cave to pressure – especially from the United States.

    China and the US are the world’s two biggest greenhouse gas emitters, so any attempt to address the climate crisis will need to involve deep emissions cuts from these two powerhouse nations.

    China’s emissions are more than double those of the US, but historically, the US has emitted more than any other country in the world.

    China and other fast developing nations have long argued that the world’s richest countries, especially those in the West, were able to become wealthy while churning out huge carbon emissions for decades.

    Relations between the US and China are at their worst in years with the world’s two largest economies feuding over a host of issues, from geopolitics to trade and technology.

    The US has said climate cooperation with China should be a standalone issue, separate from their disputes.

    But Beijing views it differently. Last year, it cut off climate talks with the US in protest at then-House Speaker Nancy Pelosi’s visit to Taiwan – in the middle of the worst heat wave China had seen in six decades.

    It also halted cooperation on other common causes issues, including communications between military and law enforcement.

    That difference in views has been on full display in Beijing, even as the two sides return to the table to restart talks.

    When meeting Wang, China’s top diplomat, on Tuesday, Kerry stressed the two countries “cannot let bilateral differences stand in the way of making concrete progress” on climate cooperation.

    But Wang insisted this cooperation “cannot be separated from the overall environment of Sino-US relations.” He urged the US to pursue a “rational, pragmatic and positive policy toward China” and “properly handle the Taiwan issue,” referring to the democratic self-ruled island that Beijing claims sovereignty over.

    On Wednesday, Kerry reiterated his message to Chinese Vice-President Han Zheng that climate should be handled separately from broader diplomatic issues, Reuters reported.

    Acknowledging the diplomatic difficulties between the two sides in recent years, Kerry said climate should be treated as a “free-standing” challenge that requires the collective efforts of the world’s largest economies to resolve, according to Reuters.

  • Climate change is making our oceans change color, new research finds | CNN

    Climate change is making our oceans change color, new research finds | CNN

    [ad_1]



    CNN
     — 

    The color of the ocean has changed significantly over the last 20 years and human-caused climate change is likely responsible, according to a new study.

    More than 56% of the world’s oceans have changed color to an extent that cannot be explained by natural variability, said a team of researchers, led by scientists from the National Oceanography Center in the UK and the Massachusetts Institute of Technology in the US, in a statement.

    Tropical oceans close to the equator in particular have become greener in the past two decades, reflecting changes in their ecosystems, according to the study published Wednesday in the journal Nature.

    The color of the ocean is derived from the materials found in its upper layers. For example, a deep blue sea will have very little life in it, whereas a green color means there are ecosystems there, based on phytoplankton, plant-like microbes which contain chlorophyll. The phytoplankton form the basis of a food web which supports larger organisms such as krill, fish, seabirds and marine mammals.

    It’s not clear exactly how these ecosystems are changing, said study co-author Stephanie Dutkiewicz, senior research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences and the Center for Global Change Science. While some areas are likely to have less phytoplankton, others will have more – and it’s likely all parts of the ocean will see changes in the types of phytoplankton present.

    Ocean ecosystems are finely balanced and any change in the phytoplankton will send ripples across the food chain. “All changes are causing an imbalance in the natural organization of ecosystems. Such imbalance will only get worse over time if our oceans keep heating,” she told CNN.

    It will also affect the ocean’s ability to act as a store of carbon, Dutkiewicz said, as different plankton absorb different amounts of carbon.

    While the researchers are still working to unpick exactly what the changes mean, what is clear, they said, is that the changes are being driven by human-induced climate change.

    The researchers monitored changes in ocean color from space by tracking how much green or blue light is reflected from the surface of the sea.

    They used data from the Aqua satellite which has been monitoring ocean color changes for more than two decades and is able to pick out differences that are not visible to the human eye.

    They analyzed color variation data from 2002 to 2022 and then used climate change models to simulate what would happen to the oceans both with additional planet-heating pollution and without.

    The color changes matched almost exactly what Dutkiewicz predicted would happen if greenhouse gases were added to the atmosphere – that around 50% of our oceans would change color.

    Dutkiewicz, who has been running simulations that showed the oceans were going to change color for years, said she is not surprised at this finding.

    “But still I found the results very sobering; yet another wake-up call that human induced climate change [has] significantly impacted the earth system,” she told CNN via email.

    Dutkiewicz told CNN it was difficult to say whether color changes could become visible to humans if the process continues.

    “If a big tipping point was reached in some places: maybe. Though you’d have to study the colors for a while to be able to pick up on the changes,” said Dutkiewicz.

    Next up, Dutkiewicz will try to better understand the color changes in different ocean regions, as well as looking into what might be causing them, she said.

  • The ‘climate kids’ want a court to force Montana’s state government to go green | CNN

    The ‘climate kids’ want a court to force Montana’s state government to go green | CNN

    [ad_1]


    Helena, Montana
    CNN
     — 

    It’s a Big Sky story fit for a big screen.

    On one side: 16 kids from ranches, reservations and tourist boomtowns across Montana – a group of wannabe climate avengers ranging in age from 5 to 22 and assembled to fight for a livable planet.

    On the other side: Montana’s governor, attorney general and the Republican supermajorities of both houses, who may have lost a three-year fight to kill the nation’s first constitutional climate case before it hit court, but are still determined to let oil, gas and coal keep flowing for generations.

    The setting is a small courtroom in Helena and the whole plot pivots around the Montana constitution, widely considered the greenest in the nation.

    “The state and each person shall maintain and improve a clean and healthful environment in Montana for present and future generations,” reads Article 9, and those pivotal words “clean and healthful environment” are also guaranteed separately in the state’s bill of rights.

    “This case is about the equal rights of children,” attorney Roger Sullivan began in his opening argument in Held vs. Montana this week, “and their need now for extraordinary protection from the extraordinary dangers of fossil fuel pollution and climate crisis that their state government is exposing them to.”

    In the half-century since the environmental promises were added to the constitution, the Treasure State has never rejected a fossil fuel project for potential harm to air or water. And this spring, after a county judge cited the constitution in pulling the permit of a new gas-fired power plant, state leaders quickly crafted House Bill 971 to make it illegal for any state agency to analyze climate impacts when assessing large projects, like power plants, that need environmental review.

    In a region full of ranchers and farmers who depend on stable weather and the kind of National Park beauty that draws millions of outdoor enthusiasts a year, the bill created the most buzz by far in the May legislative session, drawing more than 1,000 comments.

    But while 95% of the comments were opposed, according to a legislature count, the bill passed.

    “Skinny cows and dead cattle,” Rikki Held said, when asked how drought changed her family’s Broadus ranch.

    Since she was the only plaintiff of legal age when the suit was filed, the historic case bears her name. Now finally on the stand, she described with emotion what it was like to work through smoke and ash on 110°F days. “We have the technology and knowledge,” said Held, now an environmental science major at Colorado College. “We just need empathy and willingness to do the right thing.”

    One after another, her fellow plaintiffs have testified how the effects of a warming planet are already causing them physical, emotional and financial pain. “You know, it’s really scary seeing what you care for disappear right in front of your eyes,” said Sariel, a member of the Confederated Salish and Kootenai Tribes, after describing how the loss of consistent snow affects everything from native plants to tribal traditions.

    “Do you believe the state of Montana has a responsibility to protect this land for you?” a lawyer asked Sariel, who, like the other children who were under 18 when the case was filed, is being referred to only by her first name. “Yes, I do,” she replied in a soft voice. “It’s not only written in our constitution, an inherent right to a healthy land and environment, but it’s also just about being a decent person.”

    “During the course of this trial, the court will hear lots of emotions,” Montana Assistant Attorney General Michael Russell said in his opening argument. “Lots of assumptions, accusations, speculation, prognostication … including sweeping, dramatic assertions of doom that awaits us all.” But this case is “far more boring,” Russell argued, and is little more than a show trial over statutes “devoid of any regulatory authority.”

    Montana’s population of 1.1 million is “simply too minuscule to make any difference in climate change,” Russell told the court, “which is a global issue that effectively relegates Montana’s role to that of a spectator.”

    Attorneys for the plaintiffs have tried to poke holes in this argument, pointing out Montana’s outsized energy footprint.

    On Thursday, Peter Erickson, a greenhouse gas emissions expert and witness for the plaintiffs, pointed out Montana has the sixth largest per-capita energy-related CO2 emissions in the nation – behind other big energy-producing states like Wyoming, West Virginia and Louisiana.

    “It’s significant. It’s disproportionately large, given Montana’s population,” Erickson said.

    While attorneys for the state objected when Rikki Held tried to connect her mental health to the climate crisis, they have largely saved cross-examination for the experts as the plaintiffs lay out their case.

    “If the judge ordered that we stop using fossil fuels in Montana would it get us to the point where these plaintiffs are no longer being harmed in your opinion?” Mark Stermitz, an attorney for the state, asked Steven Running, professor emeritus of ecosystem and conservation sciences at the University of Montana.

    “We can’t tell in advance,” said Running, who shared the Nobel Peace Prize in 2007 as one of the scientists on the Intergovernmental Panel on Climate Change. “Because what has been shown in history over and over and over again is when a significant social movement is needed, it often is started by one or two or three people.”

    Montana's state capitol building rises above Helena, even as it is dwarfed by mountains.

    The trial is set to conclude on June 23 and is being heard before Judge Kathy Seeley, with no jury. While Seeley has no power to shut down fossil fuel use or order the end of new extraction permits, a ruling against Montana could help kill the new law outlawing climate impact analysis and set a powerful precedent for similar cases winding their ways through the courts.

    “I think we’re really at a tipping point right now,” Our Children’s Trust attorney Nate Bellinger told CNN. The Oregon-based legal nonprofit has filed similar actions in all 50 states and will go to trial in September with a group of young Hawaiians suing their state’s transportation department, claiming it is allowing rampant tailpipe pollution. The group also supports the 21 young plaintiffs in Juliana vs. United States, who will get their day in federal court after amending their complaint that actions by the federal government have caused climate change and violated their constitutional rights.

    When the Ninth Circuit put the Juliana case back on track, 18 Republican-led states – including Montana – tried to intervene as defendants and take on the so-called Climate Kids but were rejected.

    It is likely the case will reach the US Supreme Court.

    Back in the Wild West days of 1889, Montana’s original constitution was written under the guidance of a copper baron named William Clark, who claimed that arsenic pollution from mining gave the women of Butte “a beautiful complexion.”

    But less than a century later, mining and logging had done obvious harm to the rivers, skies and mountainsides of “the last best place,” just as the movements for social change and environmental protection were sweeping the nation.

    This was the backdrop when in 1972, 100 Montanans from all walks of life gathered in the town of Last Chance Gulch to hammer out a new constitution with not a single active politician among them. Mae Nan Ellingson was the youngest delegate back then, and as the plaintiffs set out to establish the intent behind “a clean and healthful environment for present and future generations,” she became the first witness in Held vs. Montana.

    “It was important, I think, for this constitution to make it clear that citizens could enforce their right to a clean environment and not wait until the pollution or the damage had been done,” she testified.

    The Montana Supreme Court agreed with her in a 1999 ruling and the majority wrote, “Our constitution does not require that dead fish float on the surface of our state’s rivers and streams before its farsighted environmental protections can be invoked.”

    Claire Vlases, one of the young plaintiffs, is hopeful the court will check the power of the legislature.

    Regardless of the verdict, it is likely that Held vs. Montana will end up in Montana’s Supreme Court, but for plaintiffs like Claire Vlases who are too young to vote, that will be just fine.

    “I just recently graduated high school, but I think that’s something everyone knows is that we have three branches of government for a reason,” she said, sitting by the river that runs through her Bozeman yard. “The judicial branch is there to keep a check on the other two branches. And that’s what we’re doing here.”

  • Cities across the Northeast experience better air quality indexes as hazardous wildfire smoke subsides | CNN

    Cities across the Northeast experience better air quality indexes as hazardous wildfire smoke subsides | CNN

    [ad_1]



    CNN
     — 

    Sorely missed blue skies are returning and cities across the northeastern US are experiencing better air quality indexes after the monstrous cloud of smoke spewed by the wildfires in Canada dissipates.

    Major metropolitan cities across Pennsylvania, New York, New Jersey, and Connecticut have air quality indexes below 100 as of Saturday morning, according to government website airnow.gov. When the index rises over 100, the air quality is classified as “unhealthy for sensitive groups.”

    For days, more than 75 million people have been trapped under a thick, orange blanket of smog as the Canadian wildfires spewed noxious fumes across the border.

    The fires in Canada have already scorched about 15 times the normal burned area for this time of the year: nearly 11 million acres — more than double the size of New Jersey — with more than 2 million acres concentrated in Quebec alone.

    As of Saturday, Philadelphia, had a “moderate.” air quality index of 59; New York City was in the “good” category with an index of 30; Jersey City, New Jersey, was “good” at 33; and Madison, Connecticut, had a “good” index of 14.

    In pictures: Canadian wildfires impact US air quality

    Last week, all four cities had air quality indexes above 150 on Wednesday, which was classified as “unhealthy.” Philadelphia had an index of 205 Wednesday morning, classified as “very unhealthy.” New York reached a level of 484 Wednesday afternoon, which is classified as “hazardous” and the highest level on record in the city since the 1960s.

    The oppressive smoke postponed professional sports games, grounded flights due to poor visibility, shuttered zoos and beaches and kept children inside at school.

    Those who did go outside were advised to wear N95 masks to protect themselves from the wildfire smoke, which is particularly dangerous because it contains tiny particulate matter, known as PM2.5, the tiniest of pollutants.

    The enormous cloud of pollution could cause long-term health effects, depending on the person and amount of exposure, said Dr. Purvi Parikh, an allergist and immunologist with NYU Langone Health and Allergy and Asthma Network.

    When inhaled, the pollutants can travel deep into lung tissue and enter the bloodstream. Healthy people may withstand “a day or two” but vulnerable groups, like children, the elderly and immunocompromised people were at much higher risk, Parikh said.

    “If people develop and keep having symptoms after the air quality returns to normal, “then they may have developed asthma or COPD as a result, and that can become chronic,” Parikh said.

    Scientists warn such routine-altering weather events are more likely to continue disrupting daily life as the planet warms, creating the ideal environment for more severe and frequent wildfires.

    Since it’s still early in the Canadian fire season, more wildfires could flare up this summer, and several US states are still suffering poor air quality, which could cause health problems.

  • Here’s what to look for in an air purifier for wildfire smoke

    Here’s what to look for in an air purifier for wildfire smoke

    [ad_1]

    With smoke from wildfires in Canada blanketing cities in the northeastern U.S., health officials are urging people to stay indoors, and wear high quality N95 masks outside.

    But indoor air can be even more polluted than outside air, particularly when smoke particles become trapped in small, confined spaces, as is happening in some homes.

    A good air purifier with a high efficiency particulate air (HEPA) filter can help clear the air inside a home or office.

    This type of filter can remove at least 99.97% of pollutants, including dust, pollen, mold, bacteria and any airborne particles with a diameter of 0.3 microns, according to the U.S. Environmental Protection Agency. 

    “It’s about filtration and ventilation, so HEPA is ideal,” Dr. Leonardo Trasande, a professor of population health at NYU Grossman School of Medicine, told CBS MoneyWatch.

    An air purifier with a HEPA filter can cost $1,000 or more if it’s designed for a large space. Consumer Reports’ top-rated air purifiers also start at around $300.

    But cheaper, do-it-yourself solutions can also work well, Dr. Trasande said. 

    He recommended the “Corsi–Rosenthal Box,” a widely used air purifier design that is easy to build yourself for less than $100. To make it, you need a box fan and five minimum efficiency reporting value (MERV)13 air filters to capture smoke. (The higher the MERV value, the more filtration it provides.) Duct-tape the filters into in a cube and mount the fan on top to capture and filter air.

    “It is a good example of balancing cost with optimizing the filtration [times] ventilation calculus,” he told CBS MoneyWatch. 

    At the very least, he recommends using air conditioners, which function by recirculating indoor air — thereby reducing pollutants. 

    What to look for in an air purifier

    Experts say the two most important features of an air purifier are their filter quality and fan size.

    “You want to make sure it has a HEPA-certified filter because that means it will be effective on these really small particles that can penetrate your lungs,” Johns Hopkins Bloomberg School of Public Health environmental professor Ana María Rule told CBS MoneyWatch. “They do a really good job of bringing clean air in and removing dirty air from the indoors.”

    For maximum effectiveness, try to match the air purifier to the size of the space you plan on using it.

    “If it’s for a bedroom, a small air purifier might be enough,” Rule said. “But you might need something bigger for a large home with tall ceilings and multiple rooms.”

    “Either contain yourself to a smaller room, or get a bigger, more powerful air purifier,” she advised. 

    Air purifier packaging typically indicates the volume of the room it is intended for. 

    How much do they cost? 

    There are thousands of different air purifiers on the market that range in price from a few hundred dollars to well into the thousands of dollars, depending on how big it is. A sleek design can also drive up the price. 

    “Sometimes the price is higher because of its size; other times it’s for the design,” Rule said.

    Other bells and whistles beyond a good filter and fan aren’t necessary. “All you need is a good HEPA Filter that is sized for the volume of your space,” Rule said.

    Consumer Reports’ top-rated air purifying products have HEPA filters that capture 99.97% of air particles as well as large, powerful fans that help draw in air particles for filtration, explained CR’s home appliance expert, Tanya Christian. 

    Most of Consumer Reports’ top-rated air purifiers retail for less than $1,000. Products appropriate for smaller apartments shouldn’t cost more than $300-$400, Christian said. 

    Consumer Reports’ top pick?

    The Coway Airmega ProX, for $999. A smaller and cheaper alternative is the Blueair Blue Pure 211i Max, which is great for a space up to 635 square feet and is available for less than $300.

    Most purifiers use filters that need to be replaced periodically, so consider how much replacement filters cost and factor that into the maintenance cost. Noise levels matter, too, particularly if the unit will be placed in a bedroom and could keep the user awake.

    It’s never a bad idea to have an air purifier in the home, especially if it includes smokers or anyone with a respiratory illness like asthma. 

    “People with pets in the house use them if a spouse is allergic so they can breathe purified air at night, or cigarette smokers will use them. People certainly bought them for Covid-19, too,” Doug Laher, COO of the American Association for Respiratory Care told CBS MoneyWatch. “It’s always a good practice, because you never know what might be floating around your home, or dust could accumulate over time.”

  • Wildfire smoke-laden haze could hang around Northeast and beyond for days, experts warn

    Wildfire smoke-laden haze could hang around Northeast and beyond for days, experts warn

    [ad_1]

    The thick, hazardous haze that’s disrupting daily life for millions of people across the U.S. and Canada, blotting out skylines and turning skies orange, should persist well into Thursday and possibly the weekend, experts say.

    Weather systems are hardly expected to budge, so the smoky blanket billowing from wildfires in Quebec and Nova Scotia that are sending plumes of fine particulate matter as far away as North Carolina is expected to continue presenting challenges.

    That means at least another day, or more, of the dystopian-style detour that’s chased players from ballfields, actors from Broadway stages, delayed thousands of flights and sparked a resurgence in mask wearing and remote work – all while raising concerns about the health effects of prolonged exposure to such bad air.

    The weather system that’s driving the great Canadian-American smoke out – a low-pressure system over Maine and Nova Scotia – “will probably be hanging around at least for the next few days,” U.S. National Weather Service meteorologist Bryan Ramsey said.

    “Conditions are likely to remain unhealthy, at least until the wind direction changes or the fires get put out,” Ramsey said. “Since the fires are raging – they’re really large – they’re probably going to continue for weeks. But it’s really just going be all about the wind shift.”

    CBS Boston Chief Meteorologist Eric Fisher notes that, “It is really early. In Canada, they’ve already burned more acres than they usually burn through an entire season through November, and their wildfire season usually gets going in July, which says we are probably just going to be seeing a lot more smoke … and we aren’t just dealing with Canada smoke, we get it in the western United States, too.” 

    Dr. Nidhi Kumar, a cardiovascular specialist and a CBS New York contributor, said breathing the air where quality is worst “is probably way worse than smoking a cigarette. … What we are dealing with right now are high levels of pollutants, toxins, carbon monoxide, and there’s such a high concentration of it in the atmosphere right now, and that’s causing not only cardiac issues for patients, [but also] pulmonary issues and just general inflammation in the body.”

    “These particles are really, really small, less than 2.5 micrometers. So what that means is that whenever we take a breath in, those particles are going straight into our lungs, deep into our lungs, and our bloodstream, and what that translates to is irritation and inflammation,” Kumar explained.

    Across the eastern U.S., officials warned residents to stay inside and limit or avoid outdoor activities again Thursday, extending “Code Red” air quality alerts in some places for a third-straight day as forecasts showed winds continuing to push smoke-filled air south.

    CBS Baltimore said early Thursday that, “Todays air quality will be far worse than yesterday as the bulk of smoke from the Eastern Canada wildfires is pushed into the Mid-Atlantic. The pictures we saw from New York City yesterday could easily be our view today.”

    The station says many Maryland school districts cancelled after-school activities for Thursday.

    In Washington, D.C., Mayor Muriel Bowser ordered schools to cancel outdoor recess, sports and field trips Thursday. In suburban Philadelphia, officials set up an emergency shelter so people living outside can take refuge from the haze.

    New York Gov. Kathy Hochul said the state was making a million N95 masks – the kind prevalent at the height of the COVID-19 pandemic – available at state facilities, including 400,000 in New York City. She also urged residents to stay put.

    “You don’t need to go out and take a walk. You don’t need to push the baby in the stroller,” Hochul said Wednesday night. “This is not a safe time to do that.”

    New York City Mayor Eric Adams said, “This is an unprecedented event in our city, and New Yorkers must take precautions.” He distributed masks to some city residents.

    The message may be getting through. Officials said Wednesday the city hadn’t seen an uptick in 911 calls related to respiratory issues and cardiac arrests.

    More than 400 blazes burning across Canada have left 20,000 people displaced. The U.S. has sent more than 600 firefighters and equipment to Canada. Other countries are also helping.

    Canadian Prime Minister Justin Trudeau spoke to President Biden by phone on Wednesday. Trudeau’s office said he thanked Mr. Biden for his support and that both leaders “acknowledged the need to work together to address the devastating impacts of climate change.”

    Canadian officials say this is shaping up to be the country’s worst wildfire season ever. It started early on drier-than-usual ground and accelerated quickly. Smoke from the blazes has been lapping into the U.S. since last month but intensified with recent fires in Quebec, where about 100 were considered out of control Wednesday.

    “I can taste the air,” Dr. Ken Strumpf said in a Facebook post from Syracuse, New York, where the sky took on the colorful nickname of the local university: Orange.

    The smoke was so thick in Canada’s capital, Ottawa, that office towers just across the Ottawa River were barely visible. In Toronto, Yili Ma said her hiking group canceled a planned hike this week, and she was forgoing the restaurant patios that are a beloved summer tradition in a nation known for hard winters.

    “I put my mask away for over a year, and now I’m putting on my mask (again),” Ma lamented.

    Eastern Quebec got some rain Wednesday, but Montreal-based Environment Canada meteorologist Simon Legault said no significant rain is expected for days in the remote areas of central Quebec where the wildfires are more intense.

    The Federal Aviation Administration tweeted Thursday morning that, “Reduced visibility from wildfire smoke will continue to impact air travel today. We will likely need to take steps to manage the flow of traffic safely into New York City, DC, Philadelphia and Charlotte.”

    CNN
     — 

    A string of sports games and practices have been postponed as smoke from Canadian wildfires continues to choke the Midwest, Northeast and Southeast parts of the United States.

    Around 75 million people are under air quality alerts as wildfire smoke shrouds major US cities, with Major League Baseball (MLB), the Women’s National Basketball Association (WNBA) and the National Women’s Soccer League (NWSL) forced to postpone games due to concerns over dangerous air quality.

    The MLB postponed two games – one between the Detroit Tigers and the host Philadelphia Phillies at Citizens Bank Park and the other between the Chicago White Sox and the New York Yankees at Yankee Stadium – on Wednesday due to medical and weather expert warnings about “clearing hazardous air quality conditions in both cities,” the league said in a statement.

    Meanwhile, the WNBA was forced to postpone Wednesday’s game between the New York Liberty and the Minnesota Lynx due to smoke impacting the Liberty’s home arena, with the league noting that information regarding the rescheduling of the game would be provided at a later date.

    The New York Racing Association (NYRA) canceled Thursday’s training at Belmont Park due to “poor air quality conditions” affecting New York state, while in New Jersey, the NWSL postponed Wednesday night’s Challenge Cup game in Harrison and rescheduled it for August 9.

    “The safety of our players, officials and fans is our top priority. Following consultation with the NWSL Medical and Operations staff, it was determined that the match could not be safely conducted based on the projected air quality index,” the NWSL said in a statement.

    Smoke from Canada’s fires has periodically affected the Northeast and Mid-Atlantic for more than a week, raising concerns over the harms of persistent poor air quality.

    More than nine million acres have been charred by wildfires in Canada so far this year – about 15 times the normal burned area for this point in the year – and more than 10,500 people have been evacuated from communities across Alberta.

    According to the MLB, the Phillies-Tigers game will take place at 6:05 p.m. (ET) on Thursday, while the Yankees and the White Sox will now play a doubleheader beginning at 4:05 p.m. (ET) on Thursday.

    The Belmont Stakes is scheduled for Saturday at Belmont Park in Elmont, New York, and the NYRA said a decision on Thursday’s live racing program will be made in the morning following a “review of the air quality conditions and forecast.”

    New York City’s air pollution ranked the worst of any city in the world on Wednesday as wildfire smoke from Canada continued to drift over the area, creating a second day of orange haze over the city and prompting some residents to wear face masks outdoors.

    As of Wednesday afternoon, the city reached an AQI of 342, a level considered “hazardous” for all residents.

    The city’s schools are open but are not having outdoor activities as the air quality is expected to deteriorate throughout the day. The Federal Aviation Administration on Wednesday halted some flights bound for New York’s LaGuardia Airport due to the smoke. Visibility was also causing delays at Newark Liberty International Airport.

    City officials have advised residents to limit outdoor activity Wednesday and warned that children, older adults and people with preexisting respiratory problems are especially vulnerable.

    Wildfire smoke releases fine particulate matter, called PM2.5, which enters the lungs and causes health issues such as asthma and bronchitis. PM2.5 concentration in New York City is currently 15 times the World Health Organization’s annual air quality guideline value.

    The New York State Department of Environmental Conservation has issued an Air Quality Health Advisory for all five boroughs. City officials have said they expect the advisory to remain in place for the next few days but added it’s particularly difficult to forecast smoke conditions.

    New York also extended its air quality health advisory to Thursday.

    Mayor Eric Adams in a press briefing Wednesday urged vulnerable residents to remain indoors and said dangerous air quality conditions are forecast to temporarily improve later tonight through Thursday morning but continue to deteriorate Thursday afternoon and evening.

    “This may be the first time we’ve experienced something like this of this magnitude,” Adams said. “Climate change is accelerating these conditions. We must continue to draw down emissions and improve air quality and build resiliency.”

    Canada is on track to experience its worst-ever wildfire season, with more than 400 active wildfires currently burning across nearly all Canadian provinces and territories. Federal officials said last week that wildfires have burned more than 6.7 million acres and about 26,000 people are under evacuation orders.

    The smoke from Canada’s wildfires has drifted south and prompted air pollution warnings across the country.

    Millions of people in the Midwest are experiencing dangerous air quality conditions, with air quality advisories in effect in southeastern Minnesota, parts of the Upper Peninsula of Michigan and areas in Wisconsin. Air quality alerts have also been posted across most of New England.

    The National Weather Service in a forecast said the smoke was expected to linger through Wednesday and continue to travel further west.

    Climate change is increasing the frequency and intensity of global wildfires and air pollution from wildfire smoke is also growing worse. Last year, Stanford researchers found millions of Americans are routinely exposed to wildfire smoke pollution at levels rarely seen only a decade ago.

     — 

    As an orange haze of wildfire smoke from Canada smothers parts of the eastern US, officials are warning residents in both countries of unhealthy or hazardous air Wednesday.

    More than 55 million people in the eastern US are under air quality alerts due to the smoke. The heaviest smoke is forecast to impact the Northeast through the Mid-Atlantic and down to the Carolinas, and smoke conditions in those regions could last through at least Thursday.

    Major metro areas in Pennsylvania, New York, New Jersey and Connecticut now have air quality indexes (AQIs) above 150 – which is considered “unhealthy,” according to the government website AirNow.gov.

    Philadelphia had an AQI of 205 as of Wednesday morning, which is classified as “very unhealthy.”

    New York City; Jersey City, New Jersey; and New Haven, Connecticut all had “unhealthy” AQIs ranging from 155 to 171 on Wednesday morning.

    And the Canadian capital of Ottawa is getting hit with some of the worst air quality, according to AirNow.gov, a partnership of the US Environmental Protection Agency, the National Oceanic and Atmospheric Administration, the US Centers for Disease Control and Prevention and other agencies.

    A woman walks her dog along the Ottawa River in Ottawa as smoke obscures Gatineau, Quebec, on Tuesday.

    While New York City, Philadelphia and Washington, DC, are expected to see their air quality improve throughout the day, the air over Boston, Pittsburgh and Raleigh, North Carolina, is expected to get worse Wednesday.

    Philadelphia issued a “code red” alert Wednesday, warning certain residents should stay indoors.

    The elderly, young children and those who are pregnant or have heart or lung conditions could experience serious health effects from the smoke, said James Garrow, spokesperson for the Philadelphia Department of Public Health.

    “For those who are not considered to be in a sensitive group, we are asking those folks to avoid strenuous activities outdoors like jogging or exercising,” Garrow told CNN Wednesday.

    “We are asking folks to avoid unnecessary time outdoors,” he said.

    “But if they need to be outdoors, they should be masked and head inside as often as they need.”

    Garrow said it’s not clear how long the code red alert will last, “or if it will change to another level of warning.”

    New York City had the worst air pollution of any major city in the world at one point Tuesday night, before dropping to second-worst behind New Delhi, India, according to air quality tracker IQair.

    The smoke has also triggered air quality alerts in parts of Massachusetts, New Hampshire, Pennsylvania, Maryland, Virginia and the Carolinas, according to the National Weather Service.

    Air quality in the US Northeast has deteriorated this week as more than 150 wildfires rage in Quebec, according to the Canadian Interagency Forest Fire Center.

    In Quebec, the entire town of Chibougamau – population 7,000 – is under a mandatory evacuation order as fast-moving wildfires wreak havoc across the region.

    “Given the current situation, the mayor of Chibougamau, Manon Cyr, has declared a state of emergency and announced the mandatory evacuation of the entire town, including the resort area,” the town announced in a Facebook post Tuesday night.

    So far this year, the province has endured more than 400 wildfires, which is twice the average for this time of year.

    More than 9 million acres have been charred by wildfires in all of Canada this year – about 15 times the normal burned area for this point in the year.

    The alarming air quality prompted New York Mayor Eric Adams to ask residents to limit their outdoor activity and state environmental officials to issue an air quality health advisory for the city through Wednesday.

    “Active children, adults, and people with lung diseases such as asthma should reduce prolonged or heavy exertion outdoors,” New York City Emergency Management said.

    The nation’s largest public school district canceled all outdoor activities Wednesday, but will remain open. At least 10 school districts in central New York state canceled outdoor activities and events Tuesday.

    Overnight Tuesday into Wednesday, the air quality index for the city topped 200, pushing it into the “very unhealthy” range, according to air quality tracker AirNow. By 7 a.m. Wednesday, New York City’s air quality index was just below 180, a designation of “unhealthy.”

    Human-induced climate change has exacerbated the hot and dry conditions that fuel wildfires.

    Scientists recently reported that millions of acres scorched by wildfires in the Western US and Canada – an area roughly the size of South Carolina – could be traced back to carbon pollution from the world’s largest fossil fuel and cement companies.

    The intense wildfire smoke hovering over the Northeast could delay flights through major cities, the Federal Aviation Administration said.

    As of noon ET Wednesday, airlines in the US have canceled 71 flights and delayed another 1,042, according to tracking site FlightAware.

    “Boston, the New York metro area, Philadelphia and the DC metro area are all experiencing some smoke that could impact travel to the airports,” Sam Ausby with the FAA said in a video posted on the agency’s Twitter account.

    Aviation weather reports show Newark Liberty International Airport is among the East Coast airports where visibility is the lowest – just 2 miles as of 11:51 a.m. ET.

    But smoke does not necessarily pose a major safety hazard for commercial flights, which can operate normally without visual reference to the ground or horizon.

    Wildfire smoke is particularly dangerous because it contains tiny particulate matter, or PM2.5 – the tiniest of pollutants.

    When inhaled, it can travel deep into lung tissue and enter the bloodstream. It comes from sources like the combustion of fossil fuels, dust storms and wildfires, and has been linked to several health complications including asthma, heart disease and other respiratory illnesses.

    And the impacts could be deadly: In 2016, about 4.2 million premature deaths were associated with fine particulate matter, according to the World Health Organization.

    “If you can see or smell smoke, know that you’re being exposed,” said William Barrett, the national senior director of clean air advocacy with the American Lung Association. “And it’s important that you do everything you can to remain indoors during those high, high pollution episodes, and it’s really important to keep an eye on your health or any development of symptoms.”

    How dangerous is U.S. air from Canada’s wildfires? Here’s how to read the EPA’s Air Quality Index.

    With hundreds of wildfires still burning in Canada, a large swath of the U.S. Northeast continues to suffer under hazy skies and compromised air into Wednesday. In fact, according to an international gauge, New York City had the second-worst air in the world early Wednesday.

    As of late Tuesday, Quebec’s forest fire prevention agency reported that more than 150 blazes were active, including more than 110 deemed out of control, the Associated Press reported. A hot, dry summer is expected for the province and beyond.

    The U.S. Environmental Protection Agency said its Air Quality Index registers above 151 in some areas of the northeastern U.S., spreading down into the Mid-Atlantic region. The upper Midwest reported concerning issues to start the week as well. Once an Air Quality Index reading clears 100, it’s typically a warning to people who have respiratory conditions, including asthma, to take precautions.

    What is the Air Quality Index?

    The EPA established an AQI for five major air pollutants regulated by the 50-year-old Clean Air Act. The agency takes readings at more than 1,000 air-quality stations around the country and includes special sensors activated by smoke in particular, for real-time readings.

    Each of these pollutants measured by the EPA requires a standard deemed important to public health:

    • ground-level ozone

    • particle pollution (also known as particulate matter, including PM2.5 and PM10)

    • carbon monoxide

    • sulfur dioxide

    • nitrogen dioxide

    Especially during wildfire season, fine particles in soot, ash and dust can fill the air. And because it’s nearly summer, the combination of smoke and hotter temperatures can generate more ozone pollution, which can aggravate respiratory issues.

    How do you read the EPA’s Air Quality Index?

    The EPA says to think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern.

    For example, an AQI value of 50 or below represents good air quality for essentially all the population. A reading above 100 typically means that the outdoor air remains safe for most, but seniors, pregnant people and children are at increased risk. Those with heart and lung disease may also be at greater risk. And an AQI value over 300 represents hazardous air quality that will impact to some degree nearly everyone exposed to the air, even healthy people.

    Because remembering the severity of number ranges may be challenging, EPA has assigned a color to each range, with green and yellow representing the most favorable conditions, and orange, red, purple and maroon reflective of levels that are progressively worse, topping out at maroon or readings between 301 to 500.

    For comparison, the record-setting wildfire years of 2020 and 2021 meant that outdoor air near Portland, Ore., on select days produced an AQI above 400.

    A separate measurement, from the international site, IQ Air, shows New York City ranking second for worst air globally Wednesday, behind Delhi, India. Detroit ranked within the top 5.

    Visit the government-run Air Now site for the latest readings.

    You can also examine longer-term air quality by select region.

    What are the health concerns from poor air quality?

    The EPA and public health officials warn citizens against regular exposure to fire-impacted air, especially for outdoor workers, even if local readings aren’t especially dangerous.

    The effects of air pollution can be mild, like eye and throat irritation. But, for some, those effects turn serious, including heart and respiratory issues. And pollutants might linger longer than hazy, discolored skies persist, causing inflammation of the lung tissue and increasing vulnerability to infections.

    Lingering particle measurements are picked up when the AQI tracks PM 2.5, which quantifies the concentration of particles smaller than 2.5 micrometers. When inhaled, these nearly undetectable particles can increase the risk of heart attack, select cancers and acute respiratory infections, especially in children and older adults.

    Smokers, including those using vape pens, can invite added health risk with wildfire smoke exposure, say public health officials.

    What precautions can be taken when there’s dangerous air outdoors? Do masks help?

    • Stay indoors if you can, with the windows and doors closed.

    • The EPA recommends eliminating outdoor exercise such as walking, jogging or cycling, once an AQI moves above 150. That includes gardening and mowing the lawn.

    • If you have to work outside, additional breaks out of the smoke may be necessary.

    • If you have air conditioning, run it continuously, not on the auto cycle. It’s also recommended to close the fresh air intake so that smoke doesn’t get inside the house.

    • But if you’re still worried about the outdoor air entering your home, air purifiers, often the size of table fans or smaller, can reduce indoor particulate matter in smaller spaces.

    • Avoid stove-top cooking that could increase indoor smoke, even if you plan to run the overhead fan.

    • Do masks help? An N95 respirator mask can filter out some of the particles. If fitted and worn correctly, the N95 mask filters out 95% of particles larger than 0.3 microns, so they’re very efficient with keeping out the 2.5-micron particles in wildfire smoke, say health officials. Notably, even an N95 does little to protect against harmful gases in wildfire smoke, including carbon monoxide.
