Arctic*heatwave*could break records

Climate scientists say these unseasonably warm weather patterns in
the Arctic region are directly linked to man-made climate change.
Temperatures throughout November and December were 5C higher than
average. It follows a summer during which Arctic ...

...bursts of Arctic warmth don’t stand alone — last month, extremely
warm North Pole temperatures corresponded with extremely cold
temperatures over Siberia. This week, meanwhile, there are large
bursts of un-seasonally cold air over Alaska and Siberia once again....
It is all looking rather consistent with an outlook that has been
dubbed "Warm Arctic, Cold Continents" — a notion that remains
scientifically contentious but, if accurate, is deeply consequential
for how climate change could unfold in the Northern Hemisphere
winter.*..*
... the result can be a kind of swapping of the cold air masses of
the Arctic with the warm air masses to the south of them. The Arctic
then gets hot (relatively), and the mid-latitudes — including
sometimes, as during the infamous "polar vortex" event of 2013-2014,
the United States — get cold.

*Arctic Continues to Run a Fever
<https://climatecrocks.com/2016/12/24/arctic-continues-to-run-a-fever/>*
A modest proposal:
When weather casters show that big map of North America with weather
systems moving across it, at the end of the spot, the view should
pull back, and show temperatures not only in North America, but
across the globe, in relation to historical averages – like the
image above from the U of Maine’s Climate re-analyzer.
<http://cci-reanalyzer.org/DailySummary/#T2_anom>
"The temperatures there of the atmosphere are on … any given day,
like 20 C warmer than they should be for this time of year,"
Jennifer Francis, a marine and coastal sciences research professor
at Rutgers University in New Jersey, told CBC News at the time...
"The ocean temperatures there are also warmer than they should be.
I’m really, really worried, and I think everyone should be."

*Warm Arctic, Cold Continents: A Common Pattern Related to Arctic Sea
Ice Melt, Snow Advance, and Extreme Winter Weather (2012 paper)*
<http://tos.org/oceanography/article/warm-arctic-cold-continents-acommon-pattern-related-to-arctic-sea-ice-melt->
ARTICLE ABSTRACT
Arctic sea ice was observed to be at a new record minimum in
September 2012. Following this summer minimum, northern Eurasia and
much of North America experienced severe winter weather during the
winter of 2012/2013. A statistical model that used Eurasian snow
cover as its main predictor successfully forecast the observed cold
winter temperatures. We propose that the large melting of Arctic sea
ice may be related to the rapid advance of snow cover, similar to
the connection made in studies of past climates between low Arctic
sea ice and enhanced continental snowfalls and glacial inception via
ice sheet growth. Regressions between autumnal sea ice extent and
Eurasian snow cover extent and Northern Hemisphere temperatures
yield the characteristic "warm Arctic/cold continents" pattern. This
pattern was observed during winter 2012/2013, and it is common among
years with observed low autumn sea ice, rapid autumn snow cover
advance, and a negative winter Arctic Oscillation. Dynamical models
fail to capture this pattern, instead showing maximum warming over
the Arctic Ocean and widespread winter warming over the adjacent
continents. We suggest that the simulated widespread warming may be
due to incorrect sea ice-atmosphere coupling, including an incorrect
triggering of positive feedback between low sea ice and atmospheric
convection, resulting in significant model errors that are evident
in seasonal predictions and that potentially impact future climate
change projections.
