What is this polar vortex of which you speak?

Up in Yellowknife, the average high temperature in January is -22. The average low is -29. At sunrise this morning — which is 10 a.m. — it was a balmy -15.

What’s going on here? It’s all part of the “polar vortex,” the “arctic hurricane” which is sending the temperatures from Yellowknife to more kindly locales.

Today, a Time editor suggested it’s part of global warming/climate change, which ought to be a tough sell at the moment.

None of this should be terribly surprising, we’re told, since climatologists have been saying for years that this was coming.

“Where’s your global warming now?” a friend posted on a social network this morning.
