New York City was quiet Wednesday evening as the remnants of Hurricane Ida rushed towards the tri-state area. At 7 o’clock in the evening, wind and rain had already fallen on the city, soaking pedestrians, and streams pouring down the sidewalks. But the subway system is working, people are drinking and walking their dogs in bars, and there is constant traffic on the city streets.

After just two hours, walking outside means putting your life in immediate danger.Heavy rain prompted the National Weather Service to issue a flash flood emergency to New York City New York City issued such a warning for the first time in history. Serving every subway line Suspended, A video from stations across the city showed waterfalls pouring down from the ceiling and down the subway steps. Geysers churned in the middle of the subway platform, and cars floated up and down like buoys on the streets above.

Approximately 150,000 customers lost power in New York, New Jersey, and Pennsylvania, and At least 24 people died In a flash flood, he was trapped at home or in a car.Timekeeping in parts of central New Jersey 11 inches of rain in less than 24 hoursAnd tornado Destroyed a block in South Jersey. Other parts of the region have also been hit hard. At least two tornadoes Landed in Maryland.Some towns in Connecticut are between Seven or eight inches Rain.

“Global warming is on us,” Chuck Schumer, the Democratic Senate Majority Leader from New York, Said at the press conference Thursday. “It’s no coincidence that when you see all the changes we’ve seen in terms of weather.” Less than two weeks after Hurricane Henry broke the rainfall record in the area, Ida hit the northeast.

It will take some time for climate scientists to accurately calculate the impact of climate change on Hurricane Ida. Destroy Louisiana and Mississippi Earlier this week, before drawing the road to the Northeast. But climate science supports Schumer’s assertion that the storm system is affected by the climate crisis.

A hurricane like Ida is a naturally occurring phenomenon. But global warming is what makes storms like Ida worse. “All storms, including Ida, are affected by this warming trend,” S.-Y. Simon Wang, professor of climate dynamics at Utah State University, told Grist earlier this week.

Before Ida rushed into the Gulf of Mexico coast, it was a tropical storm meandering in the Caribbean Sea.When it gets closer to the interior, it changes from the unusually warm sea surface temperature of the Gulf of Mexico and change Type 4 behemoth caused by entry So much damage In Louisiana and Mississippi.

When it reached the northeast, Ada was no longer an organized weather system, but it still managed to bring floods in the northeast that it had never seen since Superstorm Sandy in 2012.This is partly because climate change has Prepare for precipitation. For every degree Fahrenheit rises on the earth, the water saturation in the air increases by 4%. When the water came back in the form of rain, it was heavier than before. Compared with the 1950s, the largest downpour in the northeast now causes a 55% increase in rainfall. Fourth National Climate Assessment, And may increase by another 40% by the end of this century.

“In general, Ada is very much in line with our expectations of climate change and what we have seen in terms of the increasing trend of rainfall in these types of events,” Senior Climate Scientist Elisa Oko (Ilissa Ocko) and the Environmental Protection Fund, tell Grist.

The remnants of Ada symbolize the kind of storms that the region may encounter as global warming accelerates. It is clear that the Northeast is not fully prepared for the forecast. On Thursday, the governors of New Jersey and New York emphasized the need for climate resilience. “Because it has to do with our infrastructure, our resilience, our overall way of thinking, the scripts we use, we must move forward and get ahead of it,” Democrat Phil Murphy, Governor of New Jersey, Said“We haven’t experienced this before, but next time we should expect it,” New York Governor Kathy Hochul (Kathy Hochul) is also a Democrat. Said“I don’t want this to happen again.”

Oko said that unless we start to plan for the future in a different way, we can continue to see the kind of impact that the end of Ada has on the Northeast. “We really have to rethink what our infrastructure can handle,” she said. “This is no longer just restoring its original state. We need to think ahead of time what it needs.”
