Thin Ice
Found this on Twitter. Puts the phrase “on thin ice” in some perspective. Freaking Mid-December in total darkness up there and the ice is thin AF. Volume looks awful. Still largely open water in Chukchi Sea and northern Bering Sea and seriously recessed near Svalbard. Genuinely wondering if we will witness collapse of Arctic sea ice next warm season given this picture and relentless heat. 2016 may have set it on that track continuing into 2017 and soon ‘18. It just looks so bad yo! A major Arctic storm could shred the ice at any time frankly.

If you don’t want to cherry–pick your data to make a point, you
may want to look at the latest, updated, running annual average. The
ice, after all, has to be out there and survive those waves 24/7, 365
days of the year.

Alaska sees record-high temperatures in December
http://www.ktuu.com/content/news/Alaska-sees-record-high-temperatures-in-December-463230673.html
JUNEAU, Alaska (AP) - An unprecedented heat wave has toppled weather records across Alaska.
The
Juneau Empire reports the National Weather Service thermometer Friday
at Juneau International Airport hit 54 degrees, tying the highest
temperature recorded in December there.
General
forecaster for the Weather Service in Juneau Devid Levin says the
heat wave in Alaska is due to a big ridge of upper-level high
pressure. With the jet stream moving to the north, warm air from the
tropics has moved north, covering the state.
Records
kept by the Weather Service since 1936 say three of the 10 warmest
December days in Juneau's history have come in the past week.
It
was warmer Friday in Juneau than it was in Houston, Jacksonville,
Florida or Monterrey, Mexico.
