Analysis shows Gulf’s heat that worsened Helene 200-500 times more likely because of human-caused global heating

As Hurricane Milton bears down on Florida, fueled by a record-hot Gulf of Mexico, a new analysis has shown how the Gulf’s heat that worsened last month’s Hurricane Helene was 200 to 500 times more likely because of human-caused global heating.

Helene, one of the deadliest storms in US history, gathered pace over the Gulf before crashing ashore with 140mph (225km/h) winds.
