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.

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
