Scientists say human-caused climate change boosted the rainfall of deadly Hurricane Helene by about 10% and intensified its winds by about 11%.

Deadly Hurricane Helene, wildfires in the Amazon, an extreme monsoon downpour in India, a heat wave during the Summer Olympics, and other dangerous and devastating weather events in 2024 were all made more likely and damaging by climate change, scientists have found.

Scientists say human-caused climate change boosted the rainfall of deadly Hurricane Helene by about 10% and intensified its winds by about 11%.

Record warm water in the Gulf of Mexico, which fueled the storm's rapid intensification, was at least 200 times more likely to occur because of climate

Researchers found that Hurricane Helene was stronger, rainier, and significantly more likely because of climate change. The U.S. can expect more such storms in the future as warming continues.

Hurricane Helene's torrential rain and powerful winds were made about 10% more intense due to climate change, according to a study published Wednesday by the World Weather Attribution (WWA) group

But when Hurricane Helene hit the American climate scientist's hometown in North Carolina and flooded several of his friends' homes, the shocking experience made him rethink his research priorities.

The warming climate boosted Helene's wind speeds by about 13 miles per hour, and made the high sea temperatures that fueled the storm 200 to 500 times more likely, World Weather Attribution calculated Wednesday from Europe.
