Wildfire smoke is driving terrible air quality as new wildfire plumes arrive from Canada

SMOKE FROM CANADA WILDFIRES BLANKETS U.S. CITIES (4AMET)

(CNN) — Read the latest updates on smoke and air quality here

Massive plumes of Canadian wildfire smoke are pouring over the border into the United States, bringing dangerous air quality to more than 120 million people in the Midwest and Northeast. The polluted air will last through Saturday as new waves of smoke waft south.

Smoke shrouded skylines and caused air quality alerts to go into effect starting on Thursday from Boston to Minneapolis. Since then, elevated levels of fine particulates from the smoke drove air quality indexes well above the “hazardous” level in cities closest to the fires, including Chicago, Detroit and Toronto.

Smoke has already been an issue this summer in parts of the West, Plains and Midwest as stateside fires have burned more than 3.6 million acres, mostly in the western half of the country. But the thicker smoke that has moved over the Great Lakes and Northeast is from wildfires to the north.

In Canada, 3,500 fires have burned more than 6 million acres this summer, with a dozen blazes flaring up in Ontario in recent weeks, filling the skies with smoke drifting south, like it did in an extreme way in 2023.

Canadian wildfire activity this year is nowhere near the hyperactivity of 2023 but the combination of wildfires in Ontario and a heat dome in the central US spells smoky trouble for millions.

Planet-heating fossil fuel pollution is increasing the chance of prolonged smoke seasons as it tips the odds that extreme wildfire seasons like 2023’s — Canada’s worst season on record — won’t remain an outlier for long.

Unhealthy smoke heads for Great Lakes and Northeast

The latest round of smoke has sunk to the surface due to a weather pattern change, unlike Tuesday’s smoke plume, which largely stayed higher in the atmosphere.

As a result, air quality has deteriorated across the Northeast, Great Lakes and Midwest. Poor air quality is likely to be an issue through Saturday as the smoke lingers and new plumes arrive from the north.

Wildfire smoke contains dangerous, tiny pollutants called PM2.5 that can travel deep into the lungs or enter the bloodstream when inhaled. The minuscule particles can lead to breathing problems like bronchitis and cause inflammation that aggravates diabetes, heart disease and other health conditions.

People with lung or heart disease, children and older adults are especially at risk for smoke-related illness. The NWS advises people avoid smoke by limiting outdoor activities and keeping windows closed overnight.

The only silver lining the smoke brings is that it could dampen some of the heat. Smoke blocks sunlight, which would be welcome news for many parts of the Northeast expected to see high temperatures in the coming days.

The smoke is now streaming into the US thanks to a record-breaking heat dome parked over the central part of the country.

So far there have been several heat domes — large, slow-moving high pressure systems — this year from the West Coast to the Northeast. Air flows clockwise around these domes, but until now, none of them have been in quite the right spot to drag Canadian smoke south.

The northern edge of this week’s heat dome is perfectly placed over northern Minnesota and southern Ontario, where wildfires rage. This placement means smoke will flow east and south, right into parts of the Midwest and Northeast.

With several months left in wildfire season, the door will remain open for more Canadian smoke plumes to migrate south.

How does this smoke compare to 2023?

This time three years ago, records were being broken as 4,300 fires had already burned 25 million acres across Canada.

In June 2023, smoke consumed the New York City skyline as northerly winds pushed a wall of wildfire smoke from Quebec into the Big Apple.

The culprits were a dominant high pressure system in the Hudson Bay and a storm system over Atlantic Canada. Together, they funneled smoke into the Midwest and Northeast.

Both systems were stagnant, keeping the smoke in place for about four days.

2023’s smoke event was so far-reaching, a study from last year estimates more than 350 million people were exposed to daily wildfire smoke-induced air pollution.

Fortunately, wildfire activity in Canada started later compared to that record-setting year, making it unlikely this year’s smoke will be as pervasive.

Smoke seasons are getting worse

In the US, the window for outbreaks of unhealthy wildfire smoke is getting bigger, as fire seasons in the West have become longer and more extreme.

Climate change was found to be responsible for the majority of the increase of surface wildfire smoke. This smoke has eroded decades of air quality improvements in parts of the US, particularly in the West.

Planet-warming pollution caused approximately 15,000 more deaths in the US from wildfire particulate matter from 2006 to 2020 than would have otherwise occurred in a cooler world, a study published last year found.

‘There is freedom’: Why Asian women are leaving their husbands in their 50s and 60s

(CNN) — Eiko Toyama had waited 32 years to leave her husband.Throughout their marriage, she said, she did all the housework and childcare in their Japan home, as well as supporting the family financially. Her husband “wanted to control everything,” from her social life to professional ambitions, leaving her feeling trapped and miserable. Still, she stuck it out for their two children.That finally changed when she turned 60. Her adult sons no longer needed her, and her husband was healthy – not yet so old that he needed a caretaker. It was a precious window of opportunity, and she took it.“I was nothing but happy (after the divorce). That was my only emotion,” she said. “I was so happy I wanted to run around all over the place.”Stories like hers are increasingly common around the world as the number of “gray divorces” – splits among couples aged 50 and older – rises each year. The trend has been seen in countries like the United States and elsewhere, but takes on particular significance in Asia, where people generally live longer.Many places like South Korea, Japan, Hong Kong, Taiwan and mainland China are battling demographic crises as birth rates fall and elderly populations swell.The surge in gray divorces is also often driven by women – who have long faced restrictive gender norms in conservative Asian societies, as well as legal, financial, and social barriers to seeking divorce. That’s now changing; in Japan, for instance, among couples splitting after decades of marriage, twice as many women as men filed for divorce in 2024.This could reshape what Asia’s elderly population looks like in the coming decade: more people living alone and requiring more welfare support, as experts have predicted — but also perhaps more empowered to step out on their own.For women like Toyama, growing up in the 1960s and ‘70s, divorce was uncommon – and often met with judgment and shame.Back then, if you were a woman, “getting divorced was kind of like the end of life,” said Sangyoub Park, an associate professor of sociology at Washburn University in Kansas, who wrote a 2023 paper on late-life divorces in South Korea.That began changing in the second half of the 20th century as more women joined the workforce and pursued higher education. Gray divorces have risen steadily – particularly as Gen X began entering its 50s in the past decade, Park said.That’s an important demographic: born between 1965 and 1980, Gen X was the first generation to grow up in a globalizing Asia, watching American TV and movies. Through pop culture, they also absorbed American values such as prioritizing “personal choices rather than family obligation,” which – alongside those broader economic factors – helped gradually shift attitudes toward divorce, Park said.That’s reflected in data around the region. In South Korea last year, the number of divorces among couples who had been married at least 30 years surpassed divorces among younger couples who were married less than five years – for the first time ever.Taiwan has also seen divorces increase among long-married couples, according to government data. In Hong Kong, multiple law firms have described a surge in gray divorces, and in mainland China, the number of elderly divorces has doubled in the past 30 years.Part of this may be demographic: an aging society has a bigger pool of older people, so it’ll have more older divorces too. Young people are getting married less these days, so their divorces are also fewer.But legal reforms have also made a huge difference, creating safety nets for women who previously had to depend on their husbands’ livelihoods.For instance, South Korea ruled in 2014 that future pensions and severance pay could be included in the division of assets. That means if a housewife handled all the housework and childcare during their marriage, thus allowing her husband to work, she’s entitled to part of his elderly pension after getting divorced. Japan introduced a similar reform in 2007.These measures are especially critical given the high rate of elderly poverty in Asia. Among OECD nations, South Korea has the highest poverty rate for people over 65; Hong Kong (not an OECD member) is similarly high. While Japan ranks slightly lower, it’s still above the global average.And deep gender inequality still persists, despite these reforms.“For women in particular, the main reason they can’t get a divorce is the inability to be financially independent,” said Toyama, pointing to lower wages for women in Japan. “Once a woman becomes a full-time homemaker, it’s very hard to leave her husband and become independent.”“My two children are boys, but if I had a daughter, I would constantly tell her, ‘No matter what happens, never quit your job,’” she added.The biggest common factor across Asia is longevity, Park said – and how people are thinking differently about the final part of their lives.“Having an extra 20, 30 years creates new expectations,” with people more “willing to walk away from an unhappy, unfulfilled marriage,” he said. Divorce “is not a failure anymore – rather, it’s something new. It’s the beginning of a new chapter.”Iman Lau, 50, experienced this rebirth firsthand. Growing up in Hong Kong, her expectations for marriage were less than inspiring: spouses eat together, do activities together, and share blandly peaceful lives, she thought. “This is just how marriage is.”That mentality stayed even through years of infidelity by her husband. She would wonder: had she done something wrong, was she not good enough? He was ultimately the one to initiate the divorce despite her pleas to stay together; he even compared her to a bird who refused to fly out of an open cage.“I’m a pretty traditional woman,” she said. “In my whole life, I never thought I would get divorced.”It was a shock, as if she’d lost a limb or an organ. But it also made her realize that somewhere in that 14-year marriage, she’d lost her sense of self, neglecting her friends and interests to simply “orbit around him,” she said.She vowed to change that this year after finalizing the divorce, and threw herself into the world with determined vigor. She joined online meetup groups and made new friends. She discovered a love for the outdoors, going hiking, swimming, kayaking and snorkeling. She’s learning to play the piano and loves jazz.After traveling across Europe, she printed and hung up holiday photos in her apartment; it’s her “happy wall,” to remind her of the joy she found trekking across Sicily and camping in Georgia.“I didn’t know that life by yourself could be so spectacular,” she said.Toyama has embarked on a similar journey, describing herself as “full of life” at 63.She began livestreaming on TikTok, and created an account on a messaging app to dole out advice to people who call and text each week. She’s working to launch new business ventures including a marriage agency and a live events company.“For 32 years, I couldn’t do anything, but now I’m finally in my third year of being able to do whatever I want,” she said. The process wasn’t easy, but any challenges now are still “much better than the anxiety of being with my ex-husband,” she said. “Above all, there is freedom.”Both women described noticing an evolution in people’s attitudes when they shared news of their divorce. For Toyama, the reactions were overwhelmingly positive, with some even expressing envy. For Lau, they were more split – and in revealing ways.“Friends around my age treat it like a taboo, like you’ve had a death in the family – they don’t dare to ask about it, they’ll just say, ‘I’m so sorry,’” she said. “But with young Gen Z people, everybody congratulates me.”The increase in gray divorces might start to plateau when millennials – who got married under very different circumstances and social attitudes than their predecessors – start aging into retirement, said Park. But that’s not for another decade or so, and separations will likely continue rising until then.For those future divorcees, Lau has some encouragement from the other side. “Actually, this world is extraordinary,” she said.“Asians in particular often think divorce is like a stain or taboo in your life, like a label of failure. But that’s not true,” she added. “Just think of it as giving yourself the chance to see that you can have an even more vibrant life – as long as you’re willing to take that step.”The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
