brrrr
Whoa it is cold. I don't have a home outdoor thermometer, but wunderground tells me that it's 7 °F/-14 °C. Artic, you're drunk. Go. Home.
In case you want to be able to talk about this stuff:
"When sea-ice North of Scandinavia and Russia melts, the uncovered ocean releases more warmth into the atmosphere and this can impact the atmosphere up to about 30 kilometers height in the stratosphere disturbing the polar vortex. Weak states of the high-altitude wind circling the Arctic then favors the occurrence of cold spells in the mid-latitudes."
“It is very important to understand how global warming affects circulation patterns in the atmosphere,” says co-author Dim Coumou from Vrije Universiteit Amsterdam, Netherlands. “Jet Stream changes can lead to more abrupt and surprising disturbances to which society has to adapt. The uncertainties are quite large, but global warming provides a clear risk given its potential to disturb circulation patterns driving our weather – including potentially disastrous extremes.” -- Winter cold extremes linked to high-altitude polar vortex weakening

"Midlatitude extreme weather events, especially when they are persistent and broad-scale, have significant socioeconomic and ecosystem impacts that encompass densely populated, intensely managed, and protected natural areas. In North America alone, the last decade has been marked by several unprecedented and large-scale extreme weather events.
In 2012, for instance, record high March temperatures and the earliest spring in 112 years devastated fruit crops across the upper Midwest and Great Lakes regions. Persistent cold temperatures and heavy snowfall across Canada and the northeastern United States in the winter of 2013–14 resulted in extensive power failures and massive cancellations in airline and rail services. The severe 2012–15 drought in California culminated in the lowest reconstructed snowpack of the past 500 years in the Sierra Nevada, resulting in the broad-scale die-off of millions of trees and record wildfires.
The drought also threatened California’s economy and human welfare through diminished hydroelectric power generation and water shortages for both urban and agriculture consumers. In each of these cases, the extreme weather was associated with anomalous and persistent ridging and troughing of the Northern Hemisphere jet stream (NHJ) over North America."
