Helene rainfall boosted by human-driven climate change, studies find

Two rapid-attribution studies released Tuesday found that human-caused global warming made Hurricane Helene stronger and wetter, elements that contributed to the storm’s destructive power.

A report from

, a consortium that analyzes extreme weather events, found that Helene’s rainfall totals and winds were strengthened by human-driven climate change, with the rainfall up to 20% heavier and winds up to 7% stronger.

The consortium noted that

“Although focused studies are needed to confirm this, it is likely that the

 has contributed to both Helen’s rapid intensification and the exceptional atmospheric river that caused extreme floods over the South-Eastern US,” the consortium said in its report.

A separate report from the

in California suggested that the influence of warming due to climate change created 50% more rain over parts of Georgia and the Carolinas than otherwise would have been expected.

“Furthermore, we estimate that the observed rainfall was made up to 20 times more likely in these areas because of global warming,” the report added.

Neither of the studies have been peer reviewed or published in journals, which is normal for rapid-attribution work.

The highest official rainfall total from Helene was more than 30 inches over Busick, North Carolina, and radar estimates suggested there could have been higher amounts of up to 40 inches over the more rural areas and highest elevations of the Appalachian Mountains.
