Donald Trump rather famously complained that climate change is just an elaborate Chinese hoax, and has used New York’s frigid winter storms to mock global warming. But according to a new study in Atmospheres, New York’s brutal winters are actually evidence of the growing impact climate change is having on the United States — and it is a trend that is going to continue throughout the century.

Researchers have observed what they call a “North American winter temperature dipole,” meaning East Coast winters have brought snowstorms and sub-zero temperatures, while the West Coast has roughed mild, dry winters that bring on droughts due to the lack of snow. “We’re in this new world that’s much, much warmer with much less sea ice and that’s changing the way the atmosphere behaves,” said climate scientist Jennifer Francis. “It’s an interesting time to be studying this, but the bad news is, we’re watching this planet fall apart.”

It’s freezing and snowing in New York–we need global warming!

The occurrence of warm West/cold East winters began as early as 1980, but “has become more frequent … a trend that reflects the influence of global warming on the atmosphere in the Northern Hemisphere,” Inside Climate News writes. The pattern will continue for the rest of the century but eventually “level off as the East becomes too warm for extreme weather conditions.” Hooray? Jeva Lange
