Il Nuovo Postiglione - Canada wildfires shroud New York in apocalyptic haze

The Big Apple's mayor urged residents to stay indoors as the thick haze of pollution cast an eerie, yellowish glow over Manhattan's famous skyscrapers and delayed flights in and out the city.

More than 100 million people across America's northeast, and extending west to Chicago and south to Atlanta, were under pollution warnings after the smoke drifted hundreds of miles from Canada, the US Environmental Protection Agency (EPA) said.

"It smells like someone is doing a barbecue," said Nicha Suaittiyanon, a 30-year-old tourist to New York City from Thailand, who complained of "watery and itchy" eyes.

Forty-three-year-old lawyer Hugh Hill said his throat had been "stinging" from the harmful haze, which he likened to the smell of a wood-burning fire.

Like many New Yorkers, he chose to cover his face while out walking his dog in Central Park, normally Manhattan's green lung.

"I don't know if it's psychological or physical, but I know there's some benefit to wearing a mask. Obviously, it's not going to prevent everything, but the dog has to be walked," he told AFP.

IQAir.com, which tracks air quality around the world, said New York -- normally known for its piercing blue skies -- was enduring the worst AQI of any major city in the world. New Delhi, renowned for its pollution, was the second worst.

New York is normally outside the top 3,000 worst cities for pollution, according to the website.

- 'Hazardous' -

The Big Apple's air quality index (AQI) reached a "hazardous" 392 at 3:30 pm (1930 GMT), according to AirNow, another monitor. Five hundred is the maximum on the EPA's scale.

New York City health commissioner Aswin Vasan said the metropolis was experiencing its worse air quality since the 1960s, while New York state Governor Kathy Hochul called it an "emergency crisis" that could last several days.

All outdoor activities at New York City's public schools were suspended, with Mayor Eric Adams urging city dwellers to limit outdoor time to "the absolute necessities."

"This is not the day to train for a marathon," he told reporters.

The smog enveloped the Statue of Liberty and the Manhattan skyline, with the Federal Aviation Administration saying it had slowed traffic to and from the city's airports "due to reduced visibility."

Mathematics professor Evangelia Antonakos, 47, said she was worried about impact the high particle count would have on her five-year-old son.

"At home we closed our windows and put our air filters on," she told AFP.

Organizers canceled the opening night of a concert series in Brooklyn set to feature Corinne Bailey Rae on Wednesday due to the poor air quality.

And the actress Jodie Comer walked off the stage of her one-woman Broadway show "Prima Facie" after just ten minutes, citing breathing difficulties, and was replaced by an understudy, a spokesman for the production told AFP.

Residents of the US capital also endured an acrid smell and cloudy skies Wednesday despite sunny weather.

Washington authorities warned that the air quality was "unhealthy for people with heart or lung disease, older adults, children and teens" and canceled all outdoor activities in public schools, including sports lessons.

- 'Climate crisis' -

White House spokeswoman Karine Jean-Pierre said the situation was an "alarming example of the ways in which the climate crisis is disturbing our lives."

Scientists say warming temperatures increase the risk of the hot, dry weather that often fans wildfires.

In Canada's Quebec province, now the epicenter of the devastating wildfires that have ravaged the country, more than 11,000 locals have already been evacuated.

Another 4,000 are expected to flee by the end of Wednesday, said Quebec Premier Francois Legault.

US President Joe Biden said on Twitter that more than 600 US firefighters and other personnel, along with equipment, had been deployed to Canada to help battle the blazes.

Back in New York City, Jack Wright, a 76-year-old retired lawyer said the pollution had "kinda generated a cough all day long."

"I quit smoking 50 years ago, but it's a kind of a cough I would have when I was smoking," he told AFP, braving a walk along the East River, which separates Manhattan and Brooklyn.

Not everyone, though, was disturbed by the unusual stench that hung over the city of 8.7 million residents..

"It does not bother me. You know, New York often smells strange," said 78-year-old retiree Pamela Roderick.
