Canada wildfire smoke cloaks eastern US with haze

Smoke from Canadian wildfires again shrouded US cities in a noxious haze, delaying flights and disrupting outdoor events in what President Joe Biden called a "stark reminder" of climate change.

Thick skies and an acrid campfire smell hung over the capital Washington on Thursday and early Friday, with parts of the mid-Atlantic region reaching "Code Maroon," the highest category of the Air Quality Index (AQI), signaling hazardous conditions.

This exceeded some of the most polluted cities in the world in South Asia and China, leading many residents to wear masks to protect their health. Though improving, conditions aren't expected to return to normal until the weekend.

More than 111 million people in the United States were living under air quality alerts due to the fires, the Environmental Protection Agency said on Thursday.

"Millions of Americans are experiencing the effects of smoke resulting from devastating wildfires burning in Canada, another stark reminder of the impacts of climate change," Biden said in a statement.

He added he was sending extra resources to Canada, including "additional firefighters and fire suppression assets such as air tankers," on top of 6 00 American personnel sent in May.

The smoke blanketing the nation's capital was not immune to the city's usual political machinations.

White House spokesperson Andrew Bates hit out at congressional Republicans, saying the majority "subscribes to debunked conspiracy theories that deny the existence and nature of climate change," even amid worsening weather events.

The National Zoo meanwhile announced it would close "for the safety of our animals, our staff and our guests."

The Washington Nationals, the capital's Major League Baseball team, announced it was postponing its afternoon game against the Arizona Diamondbacks.

Hemadri Vora, a 42-year-old tourist from India's Mumbia city, was spending the day with her family in Washington after a visit to New York.

"It's a little disappointing," she told AFP at the Washington Monument, but added she was used to similar pollution levels back home. "Obviously, the pictures are not going to be very clear."

Public schools in the capital cancelled all outdoor activities including recess, physical education, athletic practices and competitions.

The Federal Aviation Administration meanwhile said low visibility had forced it to take steps to "manage the flow of traffic safely into New York City, DC, Philadelphia and Charlotte."

Environmental groups were also quick to draw attention to climate change, which is creating warmer, drier conditions that are increasing the risk and extent of wildfires.

"This is the climate crisis, here and now, causing dangerous air pollution and threatening the health of millions of people," said May Boeve, Chief Executive of 350.org.

'Reminded me of 9/11'

Skies were noticeably clearer in New York compared to Wednesday, even as the AQI remained high.

Linda Juliano, a 65-year-old secretary, gladly accepted a mask at Grand Centr al Station in Midtown Manhattan.

"I've never seen anything like it," she told AFP, describing the sepia-tinged smog that engulfed New York on Wednesday as "scary."

"It reminded me a lot of 9/11, seeing the sky all smoky and everything," said Juliano.

Meanwhile in Canada, pollution from the wildfires is expected to peak in Toronto, Environment Canada said.

With nearly 800,000 hectares affected, according to the Society for the Protection of Forests Against Fire (SOPFEU), Quebec is experiencing a historic fire season.

Twice as many blazes have been recorded this year compared to the average over the past ten years.

On Thursday, the French-speaking province still had more than 150 active fires, including nearly 90 out of control.

New reinforcements — from the United States, France and Portugal — are expected in the hours and days to come. More than 12,000 people have been evacuated within the space of a few days.

The situation remains worrisome in several regions, explained Stephane Caron, of SOPFEU.

"We are only at the very beginning of this fire season. We are now entering the period when usually there are beginning to be larger fires in Quebec," he said.

The risk of a new outbreak is rated "extreme" by authorities in the western part of Quebec.
