March 30 marked the hottest day ever recorded for the month, according to NBC New York reporting. An analysis by World Weather Attribution, an international group of scientists who study the causes of extreme weather events, concluded that the March heat would have been 'virtually impossible' without human-caused climate change. The National Oceanic Atmospheric Administration's Climate Extremes Index shows the area of the U.S. being hit by extreme weather in the past five years has doubled from 20 years ago. Climate Central meteorologist and economist Adam Smith noted that recent extremes should include the 2025 Palisades and Eaton wildfires, which were the costliest weather disaster in the United States last year. 'This is due to climate change, that we see more extreme events, and more intense ones and have so many records being broken,' said Friederike Otto, an Imperial College of London climate scientist who coordinates World Weather Attribution.
