Warming of the Arctic caused by climate change has increased the number of polar vortex outbreaks, when frigid air from the far north bathes the central and eastern United States in killer cold, a study finds.
The study in the journal Science Thursday is the first to show the connections between changes in the polar region and February’s Valentine’s Week freeze that triggered widespread power outages in Texas, killing more than 170 people and causing at least $20 billion in damage.
The polar vortex normally keeps icy air trapped in the Arctic. But warmer air weakens the vortex, allowing it to stretch and wander south. The number of times it has weakened per year has more than doubled since the early 1980s, said study lead author Judah Cohen, a winter storm expert for Atmospheric Environmental Research, a commercial firm outside of Boston.
“It is counterintuitive that a rapidly warming Arctic can lead to an increase in extreme cold in a place as far south as Texas, but the lesson from our analysis is to expect the unexpected with climate change,” Cohen said.

The sun’s so hot, I froze to death. Susannah, don’t you cry.
Snorkel. Albuquerque.See, I can do it, too. [Reily Poole in National Treasure]
Maybe the earth is flipping on it’s side and the Poles will be the equator how much money will the Democrats want to spend to fix that ,LOL
FAKE NEWS!
can someone post the journal science website?
It slid down from the Arctic? Well I guess ice is slippery.
An article this week showed that the Antarctic ice has grown by leaps and bounds. Sorry, this is yesterday’s fear mongering.
Mostly smoke.
One of my all-time favorite songs! Very apropos!
It rained all night the day I left,
The weather it was dry,
The sun so hot I froze to death;
Greta, don’t you cry.
I soon will be in New Orleans,
And then I’ll look all around,
And when I find Greta,
I fall upon the ground.
But if I do not find her,
I might surely die,
And when I’m dead and buried,
Greta, don’t you cry
Giant north south swings in the jet stream called Rosby Waves. Like when it got up to 121 in British Columbia Canada this June.
This is just another ‘FAKE NEWS’ article. One thing has nothing to do with the other.
t has to be the truth because it comes from Real Climate Scientologists.
We had an altogether mild winter here in North Florida followed by a mild summer, only three days here on the coast so far that had lows at 80 or above. Years prior that below 80 lows ended in early June or even mid May.
“Study” LMAO!
Just ask this scientician….uh…. He’ll tell ya.
Not only is the earth a spec in freezing space, but the earths core is ever slowly cooing down.
Okay, it’s plausible that an overall warmer climate could have some sort of cold weather impact somewhere, sure. That’s an interesting theory. Still, “it’s colder because it’s warmer” is a pretty big claim. It requires big proof; more than just “expect the unexpected” we get in this piece from Borenstein and Cohen. What a load.
A strong Hadley Cell will keep the jet stream and the airmass it bounds to the North the polar cell above 60° North or South latitude a weakened Hadley will allow the jet stream to wander or plunge southward.
As good of any I have seen outside the University lecture about how the earth atmospheric rotational cells work.
