FAST FIVE: NOAA Study Finds Cleaner Air Leads To More Atlantic Hurricanes

Published by on

NOAA Study Finds Cleaner Air Leads To More Atlantic Hurricanes If you blinked, you may not have noticed “the science” changing on a key issue yet again.

Got that? Cleaner air, more hurricanes, in the Atlantic.

It has also pushed the jet stream north, the report says.  Climate and hurricane scientist Jim Kossin told AP: “That's why the Atlantic has gone pretty much crazy since the mid-90s and why it was so quiet in the 70s and 80s.” He said the aerosol pollution “gave a lot of people in the 70s and 80s a break, but we're all paying for it now.” AP continued:  While aerosol cooling is maybe half to one-third smaller than the warming from greenhouse gases, it is about twice as effective in reducing tropical cyclone intensity compared to warming increasing it, said Columbia University climate scientist Adam Sobel, who wasn't part of the study.

In the Pacific, aerosol pollution from Asian nations has gone up 50% from 1980 to 2010 and is starting to drop now.

Tropical cyclone formation from 2001 to 2020 is 14% lower than 1980 to 2000, Murakami said.
