because it accounts for a major fraction of wind - blown snow redistribution within

polar regions, increase the ozone hole,» Keith said.
Because of this, ice deposits in the
polar regions are likely to be diminished in the summer period, while the build - up of ice in Tombaugh Regio may have endured for millions of years.
The differences are that the UVic model has a smaller forcing from the ice sheets, possibly
because of an insufficiently steep lapse rate (5ºC / km instead of a steeper value that would be more typical of dryer
polar regions), and also a smaller change from increased dust.
The
polar regions of Jupiter haven't been studied previously
because they are difficult to see from Earth.
Because they depend on sea ice to hunt seals, the
polar bear is considered threatened as global warming melts and thins ice in this
region.

polar regions are experiencing symptoms of chronic stress, likely
because of how climate change is affecting their habitats.
We know this
because of the ice core analysis from the
polar regions both north and south.
Ten celsius (50F) works well
because that temperature seems to be too cool for equatorial
regions and too warm for
polar regions in the mind of the average viewer.
The S
polar region is intrinsically colder
because the ice is over land and can not be melted from the bottom, thus is always reflecting energy.
The warm air above nocturnal or
polar inversions, or even stable air masses with small positive lapse rates, are warmer than otherwise
because of heat capacity and radiant + convective heating during daytime and / or
because of heating occurring at other latitudes /
regions that is transported to higher latitudes /
regions.
I am arguing that
because the area of the
polar region (higher than latitude 60) is approximately a third of the area of the tropics (lower than latitude 30), then the global temperature will be dominated by that of the tropics.
For example, conditions at the poles affect how much heat is retained by the earth
because of the reflective properties of ice and snow, the world's ocean circulation depends on sinking in
polar regions, and melting of the Antarctic and Greenland ice sheets could have drastic effects on sea level.
The surface waters around Antarctica were much fresher
because cooler
polar regions experience greater precipitation relative to evaporation.
As to your original premise that the melting of
polar (land) ice would slow down the rotation
because of sea level rise in the equatorial
regions, I am still thinking on that question.
This helps the climate scamsters,
because the climate is said to be changing in bad ways at hard to visit places, like the
polar regions.
Bottom line: Barents Sea
polar bears are loyal to this
region because the eastern portion has the habitat they require to thrive even when sea ice cover in the western portion essentially disappears for thousands of years at a time.
The largest decreases have occurred at the highest latitudes in both hemispheres
because of the large winter / spring depletion in
polar regions.
Because the GISS analysis combines available sea surface temperature records with meteorological station measurements, we test alternative choices for the ocean data, showing that global temperature change is sensitive to estimated temperature change in
polar regions where observations are limited.
Polar bears are one of the most sensitive Arctic marine mammals to climate warming
because they spend most of their lives on sea ice.35 Declining sea ice in northern Alaska is associated with smaller bears, probably
because of less successful hunting of seals, which are themselves ice - dependent and so are projected to decline with diminishing ice and snow cover.36, 37,38,39 Although bears can give birth to cubs on sea ice, increasing numbers of female bears now come ashore in Alaska in the summer and fall40 and den on land.41 In Hudson Bay, Canada, the most studied population in the Arctic, sea ice is now absent for three weeks longer than just a few decades ago, resulting in less body fat, reduced survival of both the youngest and oldest bears, 42 and a population now estimated to be in decline43 and projected to be in jeopardy.44 Similar
polar bear population declines are projected for the Beaufort Sea
region.45
The high and persistent temperatures this fall are particularly extraordinary, scientists said,

because the angle of the Sun.
It is also
because angle of incidence in the

Partly
because they give birth on mobile pack ice, harps have their pups earlier in the season than all other Arctic seals, which means that in some

Okay, I should be slightly careful here, as the expectation is really that the feedback response is not exactly linear as we double CO2, but this is thought to be
because of different
regions warming at different rates (
polar amplification, for example) than
because the response is actually non-linear.
