Like wildfires chewing through dried-out forests, hurricane after hurricane fed on extra-hot ocean water this summer and fall before slamming into communities along the Gulf Coast, causing hundreds of billions of dollars in damages and killing more than 300 people. The warmer the sea, the more potent the hurricane fuel, and the more energy a storm can consume and turn into wind. Human-made climate change made all of this season’s 11 hurricanes — from Beryl to Rafael — much worse, according to an analysis released on Wednesday from the nonprofit science group Climate Central. Scientists can already say that 2024 is the hottest year on record. By helping drive record-breaking surface ocean temperatures, planetary warming boosted the hurricanes’ maximum sustained wind speeds by between 9 and 28 miles per hour.That bumped seven of this year’s storms into a higher category on the Saffir-Simpson Hurricane Wind Scale, including the two Category 5 storms, Beryl and Milton. “Our analysis shows that we would have had zero Category 5 storms without human-caused climate change,” said Daniel Gilford, climate scientist at Climate Central, on a press call....
