The polar vortex was all over the news (and our thermostats) last year, and for many people that was first they'd heard of the alarming phenomenon. But the phrase actually originated over 150 years ago in a magazine edited by Charles Dickens, as explained in this linguistic history of the term.
Last time we checked in with the Great Lakes, it was in the bone-chilling depths of the Polar Vortex, and a record-breaking 88 percent of the lakes were frozen. Now, here we are, at the end of April, and the lakes are still 30 percent frozen, which could mean a colder summer for the country.
Just how bad was this winter? Bad. Really, really bad as this terrifying visualization of global temperatures during these last few months shows.
How much snow does it take to cancel school in your area? This map takes a look at just how much snow around the country it takes to have a snowday.

What a weird week for weather, huh? On earth, it was so cold that Canada got frostquakes. In space, a massive solar flare sent so many particles hurtling toward us that northern lights were visible outside of the Arctic circle. Here are some landscape reads for this week, taking you under the sea and deep inside of…
The US finds itself firmly in Old Man Winter's icy grip this year, with recent temperatures across the Midwest and Eastern seaboard rivaling those in Antarctica and, at times, even the surface of Mars. But what's behind this frigid weather? And, more importantly, when will it end?
A spiraling pool of cold, dense, arctic air called a "polar vortex" began its frigid sweep of the U.S. today. "It's just a dangerous cold," said National Weather Service meteorologist Butch Dye this morning. The arctic chill is expected to burden some regions of the country with the coldest weather they've seen in…
We know Earth's countless geological and climatological processes are interconnected, but this connection is particularly incredible. Wind patterns 15 to 30 miles above the Earth's surface can wreak havoc on deep ocean currents... and Earth's climate as a whole.
