The likelihood of serious sea level rise under «business as usual», and impacts on water resources may not have the acute drama associated with polar bear population decline or the possibility of massive methane clathrate releases, but they are much more likely to figure on policy makers agendas — just as other long term chronic issues (such as pensions) do.

As far as this historic period is concerned, the reconstruction of past temperatures based on deep boreholes in deep permafrost is one of the best past temperature proxies we have (for the global regions with permafrost — polar regions and mountainous regions)-- as a signal of average temperatures it's even more accurate than historic direct measurements of the air temperature, since the earth's upper crust acts as a near perfect conservator of past temperatures — given that no water circulation takes place, which is precisely the case in permafrost where by definition the water is frozen.

It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

Sea - ice biome - The biome formed by all marine organisms living within or on the floating sea ice (frozen sea water) of the polar oceans.

However, Earth's polar regions currently experience net precipitation, and the fresh water effect on the ocean density allows the surface to freeze without the need for the entire column of ocean water to reach the freezing point.

AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on land and oceans as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing water mass from equatorial latitudes and transporting this water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..

This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).

Thoughts on Antarctic Sea Ice In warm times, when southern polar waters are warm and the ice around the Antarctic continent is small, the snow falls on the ice on land and builds up.

In cold times, when southern polar waters are cold and the ice around the Antarctic continent is large, the snow falls on the ice shelves and does not feed the ice on land.

Because the deep oceans receive no heat input, at least not on the scale of the circulation time, they are fairly uniformly at the temperature of the descending polar waters, even below the equator.
