  • Stanford researchers, nonprofit help California residents manage wildfire smoke exposure

    [ad_1]

    As California sees an increasing amount of wildfires, researchers from Stanford University and a Northern California nonprofit are helping residents prepare for and manage their exposure to toxic wildfire smoke.

    Research recently published in the journal Nature projects that by 2050, smoke exposure alone will kill 70,000 people a year, with those most at risk including children, older adults, and those with lung disease.  

    Eight-year-old Nate Pham Do says he ikes a good challenge and aims high, with big plans for the future.

    “I want to be a singer or artist and be in the army and an astronaut,” he said.

    Another one of his goals is knowing how to keep his asthma under control. Nate was 2 when he was diagnosed with the chronic condition that affects the airways in the lungs, causing inflammation and narrowing of the airways.

    “It feels like you can’t breathe, and your airways get swollen, and there’s mucus in them,” said Nate.

    He and his parents have set out to learn as much as they could about asthma, as well as the techniques to control the symptoms. They also remove him from the environmental triggers and wash his face, hands, and nose.

    “All I have to say, if you have asthma, try avoid pulling the trigger,” Nate observed.

    One big trigger, wildfire smoke, is posing a unique threat. The Nature study shows that wildfire smoke is an especially toxic and dangerous form of air pollution. 

    Marshall Burke, professor at the Doerr School of Sustainability at Stanford University, said that as the climate continues to warm, expect more wildfires with a lot more smoke that contains all kinds of chemicals. 

    “Unfortunately, as wildfires burn into cities, what’s in the smoke is often what’s also in our houses,” said Burke. “Wildfires burn up cars. They burn up what’s under our sink, or in our garages, and that can be really nasty stuff that ends up in smoke that is then inhaled by humans.”

    In addition to the complex stew of chemicals, smoke also contains ultrafine particles that can penetrate the lungs and enter the bloodstream. Nearly 50 million homes in the United States are now located in or near forested areas in the wildland-urban interface, with millions more to be built.  

    Burke, one of the researchers involved in the Nature study of wildfire smoke, says the yearly smoke-related deaths will likely increase because of climate change. To address the threat, Burke and his team created a free online tool for the public, policymakers, and researchers called the Environmental Hazard Adaptation Atlas

    The tool is an interactive map that users can use to look up where they live or work and learn about the wildfire smoke risk in their area. The website will soon include what residents and policymakers can do to reduce their risk, including strategies such as removing excess fuel from forested areas to buying portable air filters to install in homes and offices.

    “Not everyone can afford a $200 air filter, so we need to make sure that people have access,” said Burke.

    The nonprofit coalition Breathe California hopes to make a difference on that front by providing air purifiers to those in need. The organization has three affiliates: Breathe California of the Bay Area, Golden Gate, and Central Coast; Breathe Southern California; and Breathe California Sacramento Region.

    “We want people to know that there are resources out there,” said Dr. Tanya Payyappilly, CEO of Breathe California of the Bay Area, Golden Gate, and Central Coast. “We go out to community centers and also work with our partners to do a lot of education and bring awareness about this root cause that is climate change.”  

    Breathe California offers other resources, including a free summer camp in Northern California for kids with asthma. While the kids have fun and bond with others who are in the same situation, they also learn about their condition, how to avoid triggers, and use medicines.

    Payyappilly told CBS News Bay Area the camp is attracting a growing number of children diagnosed with asthma and credits the parents with wanting to give their kids some good tools and techniques.

    “They wanted to come and empower themselves with knowing how to prevent triggers or their symptoms, decrease the number of ER visits because of asthma attacks or exacerbations, and also know how to treat their symptoms if they are in a situation at school when their parents are not there,” Payyappilly said.  

    “We hope that they come out of camp just with the confidence and knowledge they need to stay safe at home, at school,” said Breathe California health, education, and community outreach specialist Vivian Chang.

    “I had fun. I met a lot of friends.” Nate said.

    His dad said he believes knowledge is power.

    “We can be more informed, so that we can protect our kids, and protect each other,” said Mr. Do.

    That is perhaps the best kind of superpower as the climate continues to warm.

    Breathe California of the Bay Area, Golden Gate, and Central Coast will hold its annual Breathe Walk of Life fundraiser on Saturday at Hellyer County Park in San Jose.

  • NWS in Portland Says Hazy Conditions Likely to Continue in the Northwest Through Wednesday – KXL

    [ad_1]


    PORTLAND, Ore. — Hazy conditions thanks to lingering wildfire smoke are likely to remain in place until at least some time Wednesday according to The National Weather Service in Portland.

    They say an easterly wind flow has been in place for the weekend and much of the early part of this week.  It has brought wildfire smoke from east of the Cascades into the Portland Metro and Western Washington.

    The good news for the Willamette Valley is they do expect the easterly winds to shift to an on-shore flow perhaps sometime on Wednesday into Thursday.  Warmer temperatures will likely remain in place, but AQI readings in the 70’s, 80’s and 90’s should dissipate.

    Precipitation is forecast for Sunday into next week.

  • Weather helping Pickett Fire crews in California’s Wine Country; containment creeps higher

    [ad_1]

    Firefighters battling the Pickett Fire in California Wine Country are holding the line on acreage and continuing to increase containment with the help of favorable weather conditions, Cal Fire reported.

    The fire in Napa County near Calistoga has been burning since Aug. 21, threatening a number of vineyards and wineries within the evacuation zones. While the footprint of the fire has remained stable, smoke from the fire could impact the area’s grape harvest.

    The overnight marine layer of low clouds and fog moving in from the Pacific Ocean — in which cooler, moist air is trapped near the surface by the warmer, drier air above it — is helping crews in lower elevations, Cal Fire said in a Wednesday status report on the fire.

    Cal Fire said the fire’s containment crept up to 25%, while the size remained at 6,803 acres, about twice the size of the city of St. Helena. The fire was expected to remain in its current footprint, the agency said, which is near several vineyards.   

    Firefighters were strengthening control lines and mopping up hot spots, while damage assessment teams were working to identify structures in the fire’s path, Cal Fire said. There were at least 292 structures that were threatened by the fire, but no structures were destroyed.

    Nearly 3,000 fire personnel were working the Pickett Fire as of Wednesday afternoon. Among the resources assigned were 11 helicopters, 251 engines, 62 dozers, 35 water tenders, and 61 hand crews.

    Current Pickett Fire evacuation areas 8/26

    Evacuation orders remained in effect for the following zones as of Wednesday afternoon. Residents can find their evacuation zones at protect.genasys.com.  

    • NPA-E107-B
    • NPA-E108-A
    • NPA-E114
    • NPA-E115
    • NPA-E122-B
    • POP-E001-B
    • POP-E002-C

    Meanwhile, evacuation warnings were in effect for these zones:

    • NPA-E120
    • NPA-E121-B
    • NPA-E121-C

    The Pickett Fire started just before 3 p.m. on August 21 in the area of Pickett Road northeast of Kenefick Ranch Vineyard and Winery, outside Calistoga city limits.

    No injuries have been reported, and the cause of the fire is under investigation.

  • Wildfire smoke threatens California vineyard impacted by 2020 blaze:

    [ad_1]

    The hot and dry weather in the West creates the perfect conditions for wildfires. One currently burning in central Oregon, the Flat Fire, is threatening nearly 4,000 homes — at least four have been destroyed, officials say. Another wildfire is threatening vineyards in Northern California.   

    The Pickett Fire, the largest wildfire in the San Francisco Bay Area this year, started on Thursday and has burned more than 10 square miles. Even if flames don’t reach the orchards, smoke will impact the economic lifeblood of Napa Valley.

    More than 2,000 people have been dispatched to fight the fires, according to Cal Fire. They have so far managed to keep homes and businesses from burning, but winery owner Chris Jambois says he’s concerned about how often wildfires appear to occur.

    Chris Jambois of Black Sears Winery in Angwin, California, takes CBS News correspondent Carter Evans on a tour of his crop.

    “It’s obviously alarming to have to go through this so frequently,” Jambois told CBS News.

    He owns Black Sears Winery, where memories of the Glass Fire are still fresh. The 2020 wildfire destroyed several wineries and more than 1,500 structures in the area. 

    The Glass Fire covered more than 67,000 acres in Napa and Sonoma counties, about a two-hour drive north of San Francisco. The Pickett Fire, while smaller at nearly 7,000 acres, has taken a similar path.

    Cal Fire


    Jambois said he learned that even if vineyards are spared from the fire, smoke could still affect the grapes.

    “We lost two vintages — 2018 and 2020 — to smoke,” Jambois said, referring to the year the grapes were harvested. “Once we made it into wine, it was a bit of a disaster. We ended up having to dump it down the drain … I mean, it tasted like licking an ashtray.”

    Meanwhile, much of the western parts of the United States are enduring a relentless heat wave, which contributes to fire activity.

    The Flat Fire in Oregon’s Jefferson County was at 5% containment as of Monday, according to fire officials. It sparked on Thursday and has burned nearly 22,000 acres, Central Oregon Fire Info said. The wildfire is one of 55 large fires burning across the country, according to the National Interagency Fire Center.

    A major concern in Napa Valley is how quickly the Pickett Fire grew. Jambois said he doesn’t know whether he or his business can keep up.

    “If we do end up losing this crop, it’ll be three out of the last eight years … We’ll have some serious soul searching to do,” he said.

  • New tool combines data from multiple agencies to assess danger of wildfire smoke:

    New tool combines data from multiple agencies to assess danger of wildfire smoke:

    [ad_1]

    MINNEAPOLIS — Canadian wildfire smoke is impacting air quality again across parts of Minnesota this week. This time, the Arrowhead is the bullseye, where an alert remains in place until Thursday morning.

    The headaches, burning eyes and difficulty breathing are becoming all too common with bout after bout of wildfire smoke. In the most extreme cases, even death could be a result. 

    “Wildfire smoke is harmful to your health. And those harms can occur and do occur during a smoke wave. Before this, normally we would have to wait months or even years to get those kind of estimates of how bad the smoke wave was,” said Alistair Hayden, a professor in the Department of Public and Ecosystem Health at Cornell University.

    To help link those fatalities and hospitalizations to the harmful air quality, Hayden and other scientists at Cornell University have created a new tool combining data from the Environmental Protection Agency, Centers for Disease Control, National Oceanic and Atmospheric Administration and the Census Bureau. The goal: to help officials make real-time decisions even faster to protect the hardest hit communities.

    “Help emergency managers, public health people, people working in hospitals and the general public understand when is the level getting so high that, ‘Goodness, we really need to take action now,’” Hayden said.

    Minnesotans and Wisconsinites know all too well how bad the air quality was last year. The dashboard estimates 133 deaths in Wisconsin and 77 in Minnesota in 2023. New York, Pennsylvania and Michigan top the list with a combined estimate of more than 650 deaths.

    “The future will be smokier,” Hayden said. “And so we really need to work on how we’re gonna protect ourselves and our communities from that wildfire smoke.”

    Hayden said to date, there has never been a federal disaster declaration because of smoke. He hopes this extra data will change that to help bring in extra resources and funding when it’s needed.

  • Canadian town bracing for its last stand against out-of-control 13,000-acre wildfire

    Canadian town bracing for its last stand against out-of-control 13,000-acre wildfire

    [ad_1]

    A Canadian town is bracing for what its mayor says could be its “last stand” against a raging out-of-control wildfire that has already burned more than 13,000 acres. 

    As of Monday, the Parker Lake Wildfire in British Columbia had grown to 5,280 hectares, or 13,047 acres, the BC Wildfire Service said. It’s currently considered “out-of-control.” 

    Cliff Chapman, director of provincial operations at the service, said during a briefing on Sunday that wildfire activity in the area around Fort Nelson “increased dramatically.” 

    “The Parker Lake Wildfire started west of Fort Nelson on May 10 and exhibited fast growth and high fire behavior,” he said, saying responders were sent to the area immediately to help prepare the region and assist in evacuations. “…Extreme winds and dry conditions drove this fire towards the community of Fort Nelson.”

    He said the fire is “aggressive” and that highways in the area are closed. 

    “If you are still in Fort Nelson or anywhere in the evacuation order of the Parker Lake Wildfire, I encourage you to leave,” Chapman said. “The fuels are as dry as we have ever seen. The wind is going to be sustained and it is going to push the fire towards the community. Escape routes may be compromised and visibility will be poor as the wildfire continues to grow.” 

    Fire Behavior Specialist Ben Boghean said the next few days will be “challenging” as winds on Monday are expected to reach roughly 12.5 miles per hour. 

    “Our current fire behavior projections show the community of Fort Nelson may be impacted during the morning of May 13,” he said, adding that fire behavior is expected to be somewhat reduced on Tuesday, but the threat of the fire remains until rain hits the area. 

    The Parker Lake Fire comes as the region continues to face several years of drought, Boghean said, with the past winter seeing below-normal levels of snowpack only adding to the issue. That combination has made fires in the area’s forests more likely and easier to spread. Within four hours of the fire being detected on May 10, Boghean said it grew nearly five miles amid strong winds. 

    “This rapid growth highlighted how dry and volatile forest fuels are up here and just how much potential there is for extreme fire behavior in the area when sustained winds reach 15 kilometers an hour (about 9 miles an hour),” he said.

    Rob Fraser, mayor of the Northern Rockies Regional Municipality based in Fort Nelson, told The Canadian Press that officials and responders are bracing for what could be the town’s “last stand” against the incoming fire. 

    “That’s the exact worst-case scenario,” he said. “The first is two to three kilometers away [less than 2 miles], and if we get winds from the west anything like we did on Friday…it’s going to be extremely difficult to keep it from moving into the community.” 

    As of Sunday, Fraser said there were still several dozen households, up to 150 people, in and around the town that had not evacuated. If they stay, he warned, they could see significantly reduced or even totally paused availability of electricity or water as those supplies go to firefighters. 

    “They’ll be at their homes thinking that they’re going to be able to use their own sprinklers, electric pumps and that sort of thing to help themselves,” he warned, “and they’ll find that the resources that they need are gone.” 

    The Parker Lake Wildifre is one of more than 130 in the Canadian province, eight of which have started in just the past 24 hours, according to the B.C. Wildfire Service. While 10% of those fires are considered to be out of control, Parker Lake remains the only fire “of note,” according to the agency, meaning that it’s highly visible or poses a potential threat to public safety.

    Canadian officials previously warned that this year could see another catastrophic season after last year’s destructive blazes. So far, the country has reported 823 wildfires in 2024, a number far above the 10-year average of 717, although acres burned remain lower than that average. Currently, there are six uncontrolled fires throughout Canada. 

    “The number of fires is well above average for this time of year, and well below the 10-year average for area burned for this time of year,” the National Wildland Fire Situation Report said as of May 8. 

    Those in the U.S. have become all too familiar with raging Canadian wildfires after last summer’s blazes sent dense smoke across several states. On Monday, at least two states reported air quality impacts. Minnesota was under an air quality alert on Monday, with conditions deemed unhealthy for sensitive groups in some areas, although those conditions were expected to improve throughout the day.

    Wisconsin is also expected to see decreased air quality on Monday, according to the local National Weather Service station. Those conditions are also expected to improve throughout the day.

  • Wildfire smoke leaves harmful gases in floors and walls. Research shows air purifiers don’t stop it — but here’s how to clean up

    Wildfire smoke leaves harmful gases in floors and walls. Research shows air purifiers don’t stop it — but here’s how to clean up

    [ad_1]

    Delphine Farmer is a professor of chemistry at Colorado State University.


    When wildfire smoke turns the air brown and hazy, you might think about heading indoors with the windows closed, running an air purifier or even wearing a mask. These are all good strategies to reduce exposure to the particles in wildfire smoke, but smoky air is also filled with potentially harmful gases. Those gases can get into buildings and remain in the walls and floors for weeks.

    Getting rid of these gases isn’t as simple as turning on an air purifier or opening a window on a clear day.

    In a new study published in the journal Science Advances, colleagues and I tracked the life of these gases in a home exposed to wildfire smoke. We also found that the best way to get rid of the risk is among the simplest: start cleaning.

    The challenge of smoke particles and gases

    In December 2021, several of my friends and colleagues were affected by the Marshall Fire that burned about 1,000 homes in Boulder County, Colorado. The “lucky” ones, whose homes were still standing, asked me what they should do to clean their houses. I am an atmospheric and indoor chemist, so I started looking into the published research, but I found very few studies on what happens after a building is exposed to smoke.

    What scientists did know was that smoke particles end up on indoor surfaces – floors, walls, ceilings. We knew that air filters could remove particles from the air. And colleagues and I were just beginning to understand that volatile organic compounds, which are traditionally thought to stay in the air, could actually stick to surfaces inside a home and build up reservoirs – invisible pools of organic molecules that can contribute to the air chemistry inside the house.

    Volatile organic compounds, or VOCs, are compounds that easily become gases at room temperature. They include everything from limonene in lemons to benzene in gasoline. VOCs aren’t always hazardous to human health, but many VOCs in smoke are. I started to wonder whether the VOCs in wildfire smoke could also stick to the surfaces of a house.

    Tracking lingering risks in a test house

    I worked with researchers from across the U.S. and Canada to explore this problem during the Chemical Assessment of Surfaces and Air, or CASA, study in 2022. We built on HOMEChem, a previous study in which we looked at how cooking, cleaning and occupancy could change indoor air.

    In CASA, we studied what happens when pollutants and chemicals get inside our homes – pesticides, smog and even wood smoke.

    Using a cocktail smoker and wood chips, we created a surprisingly chemically accurate proxy for wildfire smoke and released small doses into a test house built by the National Institute of Standards and Technology. NIST’s house allowed us to conduct controlled chemistry experiments in a real-world setting.

    We even aged the smoke in a large bag with ozone to simulate what happens when smoke travels long distances, like the smoke from Canadian wildfires that moved into the U.S. in the summer of 2023. Smoke chemistry changes as it travels: Particles become more oxidized and brown, while VOCs break down and the smoke loses its distinctive smell.

    How VOCs behave in your home

    What we found in CASA was intriguing. While smoke particles quickly settled on indoor surfaces, VOCs were more insidious.

    At first, the house took up these smoke VOCs – on floors, walls and building surfaces. But once the initial smoke cleared, the house would slowly release those VOCs back out over the next hours, days or even months, depending on the type of VOC.

    This release is what we call a partitioning process: During the smoke event, individual VOC molecules in the air attach to indoor surfaces with weak chemical bonds. The process is called adsorption. As smoke clears and the air cleans out, the bonds can break, and molecules “desorb” back out into the air.

    We could watch this partitioning happen in the air by measuring smoke VOC concentrations. On surfaces, we could measure the weight of smoke VOCs that deposited on very sensitive balances and then were slowly released.

    Overall, we concluded that this surface reservoir allows smoke VOCs to linger indoors, meaning that people are exposed to them not just during the major smoke event but also long after.

    Why worry about VOCs?

    Smoke VOCs include well-known carcinogens, and high levels of exposure can induce respiratory and health problems.

    While smoke VOC concentrations in our test house decreased with time, they remained persistently elevated above normal levels.

    Given that VOC concentrations from other sources, such as cooking and cleaning, can already be high enough in homes to harm health, this additional long-term exposure source from smoke could be important. Further toxicology studies will be needed to determine the significance of its health effects.

    How to clean up when smoke gets in

    So, what can you do to remove these lingering smoke gases?

    We found that air purifiers can remove only some of the VOCs that are in the air – they can’t clean the VOCs on your floors or in your walls. They also work only when they’re running, and even then, air purifiers don’t work particularly well to reduce VOCs.

    Opening windows to ventilate will clean the air, if it isn’t smoggy or smoky outside. But as soon as we closed windows and doors, smoke VOCs started to bleed off the surface reservoirs and into the air again, resulting in an elevated, near-constant concentration.

    We realized that to permanently remove those smoke VOCs, we had to physically remove them from surfaces.

    The good news is that cleaning surfaces by vacuuming, dusting and mopping with a commercial, nonbleach solution did the trick. While some remediation companies may do this surface cleaning for you after extreme exposures, surface cleaning after any smoke event – like Canadian wildfire smoke drifting into homes in 2023 – should effectively and permanently reduced smoke VOC levels indoors.

    Of course, we could reach only a certain number of surfaces – it’s hard to vacuum the ceiling! That meant that surface cleaning improved but didn’t eliminate smoke VOC levels in the house. But our study at least provides a path forward for cleaning indoor spaces affected by air pollutants, whether from wildfires, chemical spills or other events.

    With wildfires becoming more frequent, surface cleaning can be an easy, cheap and effective way to improve indoor air quality.

    A wildfire that started in a California national park has burned tens of thousands of acres – and is so intense that it’s spewing dangerous spinning whirlwinds of fire. 

    Officials said that the York Fire ignited in Mojave National Preserve near the end of last month, burning 30,000 acres by Sunday. Dry vegetation and high winds created “extremely challenging conditions,” and in some areas, there were 20-foot flames. By the end of that same day, it spread to 70,000 acres and spread into Nevada. 

    As National Park Service officials and first responders rushed to try and contain the fire, the park’s Facebook page said that some witnesses noticed “fire whirls” on the north side of the flames. 

    “While these can be fascinating to observe they are a very dangerous natural phenomena that can occur during wildfires,” the service warned. “A fire whirl is a vortex of flames and smoke that forms when intense heat and turbulent winds combine, creating a spinning column of fire.” 

    The service said that the whirls are similar to dust devils, but form from a wildfire’s heat and energy. They can get up to “several hundred feet in height, and their rotational speed can vary widely,” officials said. 

    “This weather is extremely dangerous for firefighters battling the fires. They have the potential to spread embers over long distances and can start new fires ahead of the main forefront,” the Preserve’s Facebook post says. “Additional fire whirls can change direction suddenly, making them unpredictable and difficult to anticipate.”

    As of Tuesday morning, the York Fire had swept over 80,400 acres and is at 23% containment, according to official wildfire data. While the fire has since spread even farther to southern Utah, officials said “less fire activity than in the previous days” was observed. 

    The origins of the fire remain under investigation. Officials say it started on private land within the Mojave National Preserve. 

    “Limited visibility due to thick smoke is a challenge the firefighters are facing,” they said. “With visibility up to a mile or less in some areas it has a significant implication and causes hazardous conditions, hindering firefighting operations as it affects aerial support, ground crews’ movement, and communications between firefighting units.”

    Wildfires in Canada have been raging for weeks with more than 500 fires burning in the country, the vast majority uncontrolled. The fires are sending smoke into the U.S. and as far as Europe. Here are videos and pictures of the Canadian wildfires and their impact.

    Wildfires are burning in several Canadian provinces. In Quebec, the fires were sparked by lightning. The fires raging in Alberta have an unknown cause, but this province, as well as Saskatchewan and Manitoba, have been hit with bad droughts. This and record heat have contributed to the fires.

    Wildfires in Canada throughout May and June have created a record level of emissions and many of the fires show little sign of slowing down, according to the European Union’s Copernicus Atmospheric Monitoring Service.

    The wildfires have affected air quality in many cities — and not just in Canada, but also in the U.S. The cities closest to the source will have more intense levels of smoke and worse air quality, meteorologist Jen Carfagno and hurricane and storm specialist Greg Postel, both of The Weather Channel, told CBS News.

    How to protect your skin from wildfire smoke and air pollution – CBS News


    Watch CBS News



    Wildfire smoke from Canada has been drifting into parts of the U.S. this week — affecting cities like Chicago, Pittsburgh, Detroit and Milwaukee. Recent studies cited by the American Academy of Dermatology found smoke like this is associated with an increase in visits for skin conditions like eczema and psoriasis. New York-based dermatologist Dr. Shayan Cheraghlou joins CBS News to discuss how air pollution interacts with the skin and what can people do to protect their skin from smoke.

  • Can air quality affect skin health? A dermatologist explains as more Canadian wildfire smoke hits the U.S.

    Can air quality affect skin health? A dermatologist explains as more Canadian wildfire smoke hits the U.S.

    [ad_1]

    As Canadian wildfire smoke continues to blanket parts of the U.S. and endanger the health of millions of people, experts say there is an organ that requires just as much attention as your lungs: your skin.

    “Pollution can damage the skin by a lot of the same mechanisms that UV radiation can,” Dr. Shayan Cheraghlou, a resident dermatology physician in New York City, told CBS News. “That’s by generating reactive oxygen species that can cause premature aging of the skin, [and] can exacerbate underlying skin conditions like eczema or other inflammatory skin conditions.”

    Reactive oxygen species, according to the National Cancer Institute, are a “type of unstable molecule” that can damage DNA. Recent studies cited by the American Academy of Dermatology found wildfire smoke is associated with an increase in patient visits for skin conditions including eczema and psoriasis.

    “Your skin is one of your first line defenses against the environment,” Cheraghlou said.

    Who is most at risk for skin issues stemming from poor air quality?

    Experts say those with compromised skin barriers should be especially vigilant, such as older people and eczema patients.

    “Older patients already have fewer lipids in their skin layer,” Cheraghlou said. “It can get more burdensome for them and cause more problems.”

    What can you do to protect your skin from smoke?

    Creating a barrier between your skin and the unhealthy air is essential, according to Cheraghlou.

    “When the pollution is there, it’s even more important to consider that you have a strong barrier protection, and that means moisturizing your skin regularly,” he said. “Of course, you can’t forget your sunscreen. Just because it’s cloudy or because there’s pollution doesn’t mean that the sun’s UV [rays] can’t penetrate down and reach you.”

    Besides moisturizing and putting on sunscreen, staying inside is another good option, Cheraghlou said.

    “If you don’t need to be outside, if you do have one of these conditions that does compromise your skin barrier, it may be better to avoid doing so when pollution levels are as high as they were a couple of weeks ago, back here in New York City,” he said.

    How do you repair the damage already done to your skin because of air pollution?

    Although Cheraghlou recommends focusing on prevention, he says there are some products that can help repair damaged skin and even further build up strong barrier protection.

    “You can use topical antioxidant serums, like vitamin C serums or vitamin E serums,” he said. “These help to scavenge those reactive oxygen species up and help prevent some of that damage from occurring in the first place.”

  • Latest Canadian wildfire smoke maps show where air quality is unhealthy now and forecasts for the near future

    Latest Canadian wildfire smoke maps show where air quality is unhealthy now and forecasts for the near future

    [ad_1]

    Smoke from the wildfires raging in Canada have affected parts of the U.S. and satellite images from NASA show the smoke has even traveled across the Atlantic to Europe. Here is the expected forecast for the smoke.

    On Tuesday, parts of the Midwest saw very unhealthy levels of smoke, with Chicago, Milwaukee and Detroit experiencing some of the worst air quality in the world, according to IQ Air, which monitors the air quality index around the world,

    Areas to the East and South of these cities had moderate air quality on Tuesday and Wednesday, according to AirNow, a government site that measures air quality. 

    The smoke is traveling along the jet stream, a pattern of wind that flows from west to east. 

    An interactive map from NOAA shows the dense smoke swirling across the U.S. and flowing both southeast across Pennsylvania toward Washington, D.C. and north toward Buffalo on Wednesday into Thursday. Less dense smoke is also seen also traveling toward more eastern cities like Philadelphia and New York. 

    On Wednesday morning, Pittsburgh was at a purple or very unhealthy air quality level, according to AirNow. The sky turned hazy Wednesday morning and an air quality alert was in effect until midnight.

    National Weather Service Baltimore-Washington said a shift to northwesterly winds would bring haze from the wildfire smoke on Wednesday, and issued an air quality alert for all of Maryland, the Washington D.C. metro area and parts of Northern Virginia. The area had yellow, or moderate, air quality on Wednesday, according to AirNow. 

    Buffalo was at a red or unhealthy level Wednesday, as westerly neighbors like Detroit stayed purple, or very unhealthy. “Looking further west, worse conditions are in place and will make its way across the region today into Thursday,” according to NWS Buffalo. 

    The New York Department of Health said there was a “potential for temporary spikes in Air Quality Index levels to reach ‘Very Unhealthy’ or ‘Hazardous,’” on Wednesday. Gov. Kathy Hochul issued air quality health advisories for western and central New York and Eastern Lake Ontario on Tuesday and urged people in the state to take precautions as the smoke continued to spread through Thursday.

    NASA said Monday the smoke from Canada had spread across the Atlantic to southwestern Europe. Images from NASA’s Terra satellite show smoke over Portugal and Spain, but NASA said it has spread even further. 

    Smoke from wildfires has traveled in this way before. In 2017, NASA said smoke from West Coast wildfires traveled 3,000 miles to the East Coast. 

    In 2020, smoke from the massive brushfires in Australia circled the globe, passing South America and reaching back to Australia where they originated, according to NASA.

    Poor air quality impacts millions for second day


    Hazardous air conditions from wildfire smoke impacts millions of Americans for second day

    03:49

    Travelers flying in or out of the Northeast may want to check on the status of their airport on Thursday, with wildfire smoke from Canada causing more flight disruptions for a second day. 

    On Thursday morning, the Federal Aviation Administration put a ground stop on departures from Philadelphia International Airport, citing low visibility, while departures from LaGuardia airport in New York City had an average ground delay of almost an hour, according to agency data.

    The FAA tweeted Wednesday morning that it would “likely need to take steps to manage the flow of traffic safely into New York City, DC, Philadelphia and Charlotte.”

    In addition to the ground stop on departing flights from Philadelphia, the agency added that it had paused in-bound flights on Wednesday morning to Philadelphia, as well as for New York City’s LaGuardia, coming from the Northeast, Mid-Atlantic and Ohio due to low visibility. 

    The agency also issued a ground delay for Newark airport on Thursday morning.

    The delays and ground stops come after all flights to LaGuardia were paused on Wednesday, while New York City’s John F. Kennedy International Airport experienced arrival and departure delays. Images from New York City on Wednesday showed an apocalyptic-looking scene, with its skyline dimmed by smoke and the air a burnt-orange color. 

    The Northeast has been blanketed by smoke from the Canadian wildfires, prompting warnings about air quality across the region and prompting schools to cancel after-school events and employers to tell workers to stay home. 

    Passengers can check real-time flight information at the FAA’s website, U.S. Secretary of Transportation Pete Buttigieg tweeted on Wednesday evening.

    Meanwhile, some airlines urged travelers to check their apps and websites to monitor for delays or other 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 impacts more than our health — it also costs workers over $100B a year. Here’s why.

    Wildfire smoke impacts more than our health — it also costs workers over $100B a year. Here’s why.

    [ad_1]

    With the smoke from burning Canadian forests enveloping the U.S. Northeast, major cities fell silent this week. Public schools canceled outdoor activities, companies sent workers home, performances were postponed, libraries shut their doors and professional baseball games were canceled.

    Such disruptions in ordinary urban life illustrates the wide-ranging economic toll of climate change, which experts say is making wildfires more intense and contributing to air pollution.

    “It’s gray and the sun looked orange in the sky this morning, like Star Wars or something,” Paul Billings, national vice president for public policy at the American Lung Association, told CBS MoneyWatch from Washington, D.C.

    “It’s really early in the season, we’re still in the spring, and we’re seeing these wildfires in Canada and the U.S. that are impacting air quality across the eastern United States. In New England, across the mid-Atlantic and into Minnesota, we’re seeing elevated levels of particulate matter or soot,” he added.

    These tiny particles are especially dangerous for people with heart disease, asthma or chronic obstructive pulmonary disease (COPD), but they carry risks for everyone, including risks of asthma attacks, heart attack, stroke or early death.

    “Some people need to take their medication more — others end up in the emergency room,” Billings said.

    Because the kind of particles found iin smoke are so small, they get past the body’s natural defenses, such as mucus membranes in the nose and throat as well as the body’s coughing mechanism. 

    “They penetrate deep in the lungs and where you have oxygen exchange systems,” Billings said. “These particles actually get into your blood and create a wide range of poor health outcomes, including stroke, heart attacks and different kinds of cancer.”


    Canada wildfire smoke prompts air quality advisories for millions

    04:21

    Forest fires aren’t the only source of particulate matter — diesel trucks and coal-fired power have historically contributed the lion’s share of air pollution. But wildfires are a growing factor. The increased frequency of wildfires in a hotter, drier climate has reversed some of the improvements in air quality since the 1970 Clean Air Act, the American Lung Association noted in an April report.

    “Staggering” costs

    The earth’s warming climate is contributing to the problem, with temperatures in Canada unseasonably high this year. Lytton, British Columbia — typically a temperate town — hit a record high of 121 degrees last week, tying California’s Death Valley. Hot, dry weather makes it more likely that a forest will catch fire and burn longer. Already, Canada’s wildfire season is on track to be the most destructive in the country’s history.

    Globally, air pollution kills more than 3 million people a year, according to the World Health Association. In dollar terms, the costs are vast and reflected in increased hospitalizations, missed work and school days, and lower worker productivity. 

    “The costs are staggering,” Billings said

    Air pollution adds $2,500 a year to a typical American’s medical bills, a recent study from the Natural Resources Defense Council found. Across the U.S., smoke, factory output and car exhaust cost the economy $800 billion a year, or about 3% of the nation’s total economic output, the NRDC found.

    Perhaps unsurprisingly, high levels of air pollution also reduce earnings by making it harder and more unpleasant to work, adding a significant drag on the economy. Outdoor workers, such as delivery people, and landscapers and teachers are most affected, but office workers aren’t necessarily safe. Even indoor air pollution spikes to three or four times safe levels during a wildfire event, studies have found.

    $125 billion in lost pay

    Researchers at Stanford who mapped wildfire plumes across the U.S. found that a single day of smoke exposure lowers a person’s quarterly earnings by 0.1%, according to a recent working paper published by the National Bureau of Economic Research. Across the U.S. as a whole, workers lost $125 billion a year due to wildfire smoke, the paper found — about 2% of all labor income.  

    Aside from smoke, hotter air also increases production of ozone, a major component of smog and a lung irritant. “Some researchers have likened it to sunburn on the lungs — your cells get irritated and weep,” Billings said.

    As with other kinds of pollution, the effects of ozone, smog and smoke aren’t evenly distributed, with low-income people and people of color more likely to be exposed, according to the ALA. 

    Businesses and governments can take some steps, like improving indoor filtration, not forcing workers to go outside and alerting issuing public service alerts about air quality. But reducing the toll of air pollution long-term means widespread electrification, Billings said. That would reduce emissions from transportation and factories.

    “I think too often, people look at these as anomalous weather events,” he said. “This is not some happenstance of a fire. It’s early June. There have always been fires, but the big driver that is creating these hot, dry conditions that are creating the opportunities for these fires is climate change.”

    New York City schools, corporations and local sports groups canceled outdoor activities Wednesday to limit residents’ exposure to smoky air caused by hundreds of wildfires in Canada. 

    Google told workers at offices across the U.S. and Canada to work from home instead of reporting to the company’s headquarters, a spokesperson told CBS MoneyWatch. Workers at the internet giant’s offices in New York; Detroit; Washington, D.C.; Pittsburgh, Pa. Raleigh and Durham, N.C.; Toronto; and Waterloo, Ontario, were excused from reporting to Google’s office Wednesday over air quality concerns.  

    New York City public schools remained open Wednesday but cancelled all outdoor activities. “We urge everyone to reduce prolonged or heavy exertion outdoors,” the school district said on Twitter.

    Due to low visibility, the Federal Aviation Administration delayed flights to New York City’s LaGuardia Airport, as well as departures from Newark Liberty International Airport in New Jersey and to Philadelphia International Airport. 

    The Yankees on Wednesday cancelled a game against the Chicago White Sox at Yankee Stadium over poor air quality. The Philadelphia Phillies also postponed a Wednesday home game against the Detroit Tigers. 

    Across New York, recreational sporting organizations scrapped planned activities, with Big City Volleyball canceling games that had been scheduled to take place Wednesday and youth soccer teams telling players not to show up for practice. A five-kilometer run, part of the Al Goldstein Speed Series of races hosted by the Prospect Park Track Club in Brooklyn, was also scratched Wednesday due to “poor air quality.” 

    New York City Mayor Eric Adams said New Yorkers should limit outdoor activity Wednesday while noting that children, older adults and those with heart or breathing problems may be “especially sensitive and should avoid outdoor activities during this time.”

    “This is an unprecedented event in our city, and New Yorkers must take precautions,” he said.

    Early Wednesday, New York City was second only to Delhi, India, for the worst air quality and pollution out of 100 tracked countries, according to Swiss air quality technology company IQAir. According to the company, the city has an Air Quality Index of 160, categorized as an “unhealthy” amount, meaning that some people may experience health effects.

    Perhaps unsurprisingly, high levels of air pollution also reduce earnings by making it harder and more unpleasant to work, adding a significant drag on the economy. Outdoor workers, such as delivery people, and landscapers and teachers are most affected, but office workers aren’t necessarily safe. Even indoor air pollution spikes to three or four times safe levels during a wildfire event, studies have found.

    $125 billion in lost pay

    Researchers at Stanford who mapped wildfire plumes across the U.S. found that a single day of smoke exposure lowers a person’s quarterly earnings by 0.1%, according to a recent working paper published by the National Bureau of Economic Research. Across the U.S. as a whole, workers lost $125 billion a year due to wildfire smoke, the paper found — about 2% of all labor income.  

    Aside from smoke, hotter air also increases production of ozone, a major component of smog and a lung irritant. “Some researchers have likened it to sunburn on the lungs — your cells get irritated and weep,” Billings said.

    As with other kinds of pollution, the effects of ozone, smog and smoke aren’t evenly distributed, with low-income people and people of color more likely to be exposed, according to the ALA. 

    Businesses and governments can take some steps, like improving indoor filtration, not forcing workers to go outside and alerting issuing public service alerts about air quality. But reducing the toll of air pollution long-term means widespread electrification, Billings said. That would reduce emissions from transportation and factories.

    “I think too often, people look at these as anomalous weather events,” he said. “This is not some happenstance of a fire. It’s early June. There have always been fires, but the big driver that is creating these hot, dry conditions that are creating the opportunities for these fires is climate change.”
