Does the polar vortex disprove climate change? Yeah right.

Dear MoveOn member,

It's freezing out! Literally. And the frigid weather most of the country is facing—with windchills still as low as minus 50 degrees F in some places—has brought out the climate deniers yet again.

The cold weather we're experiencing is originating in the polar vortex—a whirlwind of Arctic air in which temperatures drop when the North Pole is pointed away from the sun.¹ The Arctic is actually warming twice as fast as much of the Earth, and the jet streams that trap its frigid air are weakening. Cold snaps like the one we're experiencing are a normal part of winter weather—and some climate scientists think the melting Arctic is actually making this sort of "polar vortex" event more likely.²

But while the vortex science may sound complicated, one thing is crystal clear: global warming is very real—and hugely dangerous. That's why we've partnered with our friends at Forecast the Facts to give members the proof they need to counter Fox News' climate change-denying talking points.

Can you share our graphic today so your friends know how climate change deniers' claims are full of hot air?

After you share the graphic, sign Forecast the Facts' petition demanding that The New York Times follow the lead of The Los Angeles Times and stop publishing the letters of climate deniers.

Thanks for all you do.
