As 2016 continues on its march toward becoming the hottest year on record, the Arctic is seeing extreme warmth beyond anything previously recorded at this time of year—prompting alarm from climate scientists around the world.
"Folks, we're in a climate emergency," tweeted meteorologist Eric Holthaus.

The temperature at the North Pole as of Thursday was a stunning 36ºF (20°C) above normal.
The bizarre heat is fueling the rapid melt of the pole's ice caps, and it is particularly unusual because it's all happening during the polar night—the time of year when the North Pole never sees the sun, observed UCLA climate scientist Daniel Swain:

The cause? According to the Washington Post, it's the result of an elongated jet stream propelling hot air farther north than normal—which is caused by climate change.
"The Arctic warmth is the result of a combination of record-low sea-ice extent for this time of year, probably very thin ice, and plenty of warm/moist air from lower latitudes being driven northward by a very wavy jet stream," Jennifer Francis, an Arctic specialist at Rutgers University, told thePost.
The Washington Post continued:
Francis has published research suggesting that the jet stream, which travels from west to east across the Northern Hemisphere in the mid-latitudes, is becoming more wavy and elongated as the Arctic warms faster than the equator does.
"It will be fascinating to see if the stratospheric polar vortex continues to be as weak as it is now, which favors a negative Arctic Oscillation and probably a cold mid/late winter to continue over central and eastern Asia and eastern North America. The extreme behavior of the Arctic in 2016 seems to be in no hurry to quit," Francis continued.
Another culprit is that areas of open ocean water are showing unusually hot surface temperatures, according to Mark Serreze, director of the National Snow and Ice Center, who was quoted by environmental writer Hannah Waters on Twitter.
Serreze commented to the Washington Post: "There are some areas in the Arctic Ocean that are as much as 25 degrees Fahrenheit above average now. It's pretty crazy."
The alarming Arctic weather happens during the United Nations climate conference in Morrocco, and as environmentalists and climate scientists in the U.S. grapple with the prospect of a president-elect who denies the existence of climate change. Things are indeed not looking good for the planet, experts warn.
