Climate change in the spotlight after northeast US floods

The role of climate change in New York’s deadly flash floods and the city’s creaking infrastructure were under the spotlight Friday after torrential rains left at least 47 people dead across the US northeast.


“We are in a whole different world,” New York Mayor Bill de Blasio said after the remnants of Hurricane Ida drenched the biggest city in the United States. “This is a different challenge.”

Record rainfall turned streets into rivers, shut down subway services as water cascaded onto tracks, and drowned nearly a dozen people in their basement apartments.

“It’s no big surprise that the city seems to break down every time there’s a big storm,” said Jonathan Bowles, executive director of the think-tank Center for an Urban Future.

“The city’s infrastructure hasn’t kept pace with the population growth that New York’s had in the last couple of decades, let alone the increasing ferocity of storms, and rising sea levels that have come with climate change,” Bowles said.

While there has been lots of investment in big projects—train stations, airports, new bridges—less funding has gone to “unsexy” projects such as sewer lines and water mains, he said.

Nicole Gelinas, an urban economics expert at the Manhattan Institute, another think-tank, said New York’s infrastructure “was not built for seven inches of rainfall in a few hours.”

Drains for the city’s sewer system get clogged, Gelinas said, and “there’s not enough green space to catch some of the water before it runs into the drains.

“So some of these avenues, they become canals when there’s a big storm.”

New York, New Jersey and Pennsylvania were the hardest hit by Ida, which ravaged the southern state of Louisiana and Gulf Coast earlier in the week before delivering a blow to the northeast.

President Joe Biden, who has made threats from climate change a priority, on Friday headed to Louisiana, where more than 800,000 people remained without power after Ida made landfall as a Category Four storm.

‘Matter of life and death’

Biden was expected to use his trip to New Orleans to highlight the links between increasing episodes of extreme weather and the broader global climate crisis.

Speaking on Thursday, Biden said Hurricane Ida and uncontrollable wild fires in the western United States are “yet another reminder” of the crisis.

“It’s a matter of life and death and we need to meet it together,” he said in a speech at the White House.

New Jersey Governor Phil Murphy said Storm Ida had left 25 people dead in his state, most of them “individuals who got caught in their vehicles.”

Thirteen deaths were reported in New York City including 11 victims who could not escape their basements, police said.

Three people were killed in the New York suburb of Westchester, while another five died in Pennsylvania and one—a state trooper—in Connecticut, officials said.

“I’m 50 years old and I’ve never seen that much rain ever,” said Metodija Mihajlov whose Manhattan restaurant basement was flooded with three inches of water.

“It was like living in the jungle, like tropical rain. Unbelievable. Everything is so strange this year,” Mihajlov told AFP.

The National Weather Service recorded 3.15 inches of rain in New York’s Central Park in just an hour—beating a record set just last month during Storm Henri.

The US Open tennis tournament was halted as howling wind and rain blew under the corners of the Louis Armstrong Stadium roof.

It is rare for such storms to strike America’s northeastern seaboard and comes as the surface layer of oceans warms due to climate change.

The warming is causing cyclones to become more powerful and carry more water, posing an increasing threat to the world’s coastal communities, scientists say.

“Global warming is upon us and it’s going to get worse and worse and worse unless we do something about it,” said New York Senator Chuck Schumer.
