“Specifically, from event attribution, we do note that when hurricanes occur, the rainfall associated with them is more intense because of human-induced climate change, and Ida will not be an exception.” “What we can say, without doing a dedicated attribution study, is that major hurricane occurrences (categories 3-5) have increased in recent decades, which cannot be explained by natural variability alone,” Friederike Otto, who co-leads the World Weather Attribution initiative, told CNN in an email. Storm Ida causes flooding in the Ditmas Park neighborhood of Brooklyn, New York City, on Wednesday. It’s too early to make such an estimate for Ida, but trends in hurricanes of this force suggest a link. Scientists are now able to analyze exactly how much of a role climate change is likely to have played in a particular weather event. Hurricane Ida was a prime example of those changes, and scientists say storms like this will become more common as the planet warms. They are producing more rainfall, moving slower once they make landfall and generating larger storm surges along the coast. In terms of hurricanes, climate change is making them more dangerous.
Global analyses show that the amount of water vapor in the atmosphere has in fact increased over both land and oceans,” the report says. “Warmer air can contain more water vapor than cooler air. Weather and climate disasters have been getting more frequent since the '70sĪcross continental US, specifically, the heaviest downpours have been observed to be increasing in all regions, with the northeast showing the largest increase, according to the US National Climate Assessment.

TWIN BRIDGES, CALIFORNIA - AUGUST 30: A chairlift at Sierra-at Tahoe ski resort sits idle as the Caldor Fire moves through the area on Augin Twin Bridges, California. New York Governor Kathy Hochul said she could not guarantee responders could rescue people that may be stuck in their cars “if it starts floating away like a boat on a river.” We’re seeing a kind of rainfall – we almost never see this kind of speed with which the rain has come,” New York City Mayor Bill de Blasio said, urgently calling on everyone to stay at home. Meteorologists – who knew storms and floods were on their way, even roughly how much rain would fall – were also surprised at the storm’s pace. Officials in New York appeared totally caught off guard by the floods.
These are the kinds of scenes that scientists say the world will see more of because of human-caused climate change. The neighboring city of Newark, New Jersey, saw the heaviest single day of rain on record. Ida dumped heavy amounts of rain on Central Park and the subway was inundated with fast-moving floods, knocking nearly the whole system out of operation. After Hurricane Ida battered the southern US states, its remnants lashed the northeast on Wednesday night, transforming New York City into a danger zone Thursday morning.
