Mori et al. identified two circulation patterns that drove winter temperatures in Eurasia from 1979 to 2013: the Arctic Oscillation (which confines colder air to the polar latitudes) and a pattern dubbed «Warm Arctic and Cold Eurasia» (WACE), which correlated both to sea -
ice loss in the Barents - Kara Sea and to particularly cold winters; its impact has
more than doubled the probability of severe winters in central Eurasia.
Velicogna and her colleagues also measured a dramatic
loss of Greenland

After two decades of rapid

more ice will be lost to the ocean in the future.
«I've accepted that the
loss of sea
ice, not subsistence [hunting of the animal] or the oil and gas industries, is the reason for the threat to the polar bears,» which are already protected by the
more stringent Marine Mammal Protection Act of 1972, Kempthorne said.
They then used the satellite record of Arctic sea

Loss of
ice would mean
more mercury in the air would land directly on water, instead of bouncing back as a gas.

loss all over Greenland by that much, but it brings a
more significant change to our understanding of where within the
ice sheet that
loss has happened, and where it is happening now.»
Totten Glacier, one of East Antarctica's largest ocean outlets, is already thinning — an ominous sign, since this single glacier drains enough
ice to raise the sea level
more than all of West Antarctica's
ice loss would.
He says previous predictive models of Greenland's
ice loss did not adequately take into account the faster movement of its southern glaciers, which is accelerating the amount of
ice entering the ocean: «Greenland is probably going to contribute
more to sea level rise, and faster than predicted by these models.»
Sea
ice and snow cover
loss create a feedback look that can accelerate global warming; with fewer reflective surfaces on the planet,
more sunlight can thereby be absorbed, driving surface temperatures even higher, the scientists explained.
The recent string of record - low winter maximums could be a sign that the large summer
losses are starting to show up
more in other seasons, with an increasingly delayed fall freeze - up that leaves less time for sea
ice to accumulate in winter, Julienne Stroeve, an NSIDC scientist and University College London professor, previously said.
Scientists are looking at the link between the
loss of Arctic sea
ice and how it affects weather in lower latitudes, but
more research is needed.
It's a research approach new to glaciology that could lead to
more accurate predictions for
ice - mass
loss and global sea - level rise.
By 1900, increased emissions of soot could have triggered the
loss of
more than 15 m of
ice from a glacier's surface; by 1930, the
loss could have totaled 30 m or
more — magnitudes and timing that can easily account for the Alpine glacial retreat, the scientists contend.
Previous studies have suggested that Arctic sea -
ice loss causes the NAO to spend longer in its «negative phase» - generating
more easterly winds that bring colder air from Scandinavia and Siberia to the UK.
The dramatic
loss of Arctic sea
ice through climate change is unlikely to lead to
more severe winter weather across Northern Europe, new research has shown.
Because of this it has been reasonable to think that we would experience
more severe winter weather if Arctic sea -
ice loss intensifies the negative phase of the NAO».
«While
more research should be done, we should be aware that an increasing number of studies, including this one, suggest that the
loss of Arctic sea
ice cover is not only a problem for remote Arctic communities, but could affect millions of people worldwide.»
Loss of
ice cover in the Arctic could spur
more droughts in California, according to a new study by federal researchers.
«This research indicates that although sea -
ice loss does intensify the negative NAO, bringing
more days of cold easterly winds, it also causes those same winds to be warmer than they used to be.
The difference could point to a problem with the models, which attempt to account for effects such as the
loss of glaciers and

more space.
And if
ice loss continues to accelerate in the warming Arctic, this effect may only become
