Climate change fueled extreme rainfall during the record 2020 hurricane reason

Human-induced climate change fueled one of the most active North Atlantic hurricane seasons on record in 2020, according to a study published in the journal Nature.

The study analyzed the 2020 season and the impact of human activity on climate change. It found that hourly hurricane rainfall totals were up to 10% higher when compared to hurricanes that took place in the pre-industrial era in 1850, according to a news release from Stony Brook University.

"The impacts of climate change are actually already here," said Stony Brook's Kevin Reed, who led the study. "They're actually changing not only our day-to-day weather, but they're changing the extreme weather events."

There were a record-breaking 30 named storms during the 2020 hurricane season. Twelve of them made landfall in the continental U.S.

These powerful storms are damaging and the economic costs are staggering.

Hurricanes are fueled in part by moisture linked to warm ocean temperatures. Over the last century, higher amounts of greenhouse gases due to human emissions have raised both land and ocean temperatures.
