The Arctic is warming more than twice as fast as the rest of the planet, because as ice melts at the top of the world, there is less of it to reflect sunlight back into space, so more of it is absorbed by ocean waters; more absorbed sunlight means even warmer temperatures, which means more ice melt a circular process known as Arctic amplification.

Back - of - the - envelope calculations show that the latent heat absorbed by melting of ice after surges (e.g., the melting of > 1500 years of ice accumulation during Dansgaard - Oeschger events — which seem to have happened in unison across the northern hemisphere, or the longer > 5ky Bond cycles) can significantly contribute to the global energy balance.

There are subtle effects such as the planet losing more heat from the open sea than from ice - covered region (some of this heat is absorbed by the atmosphere, but climates over ice - covered regions are of more continental winter character: dry and cold).

Since it reflects the capacity of the climate system to absorb heat, it may be influenced by the planetary albedo (sea - ice and snow) and ice - caps, which respond to temperature changes.

Surface melt on the ice sheet is constrained by the albedo, but a lake is dark and could absorb much more solar radiation.

The particulate matter that is released into the atmosphere by industry and automobiles settles on the ice, making it darker and causing it to absorb more heat.

The exposed open water caused by the wind divergence may absorb some additional sunlight and melt more ice than usual over the next few weeks (temperature - albedo feedback)[related NASA animation], but given that the sun is well on its way to setting for the winter, I think this effect will be fairly minimal.

For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying out due to heat & drought & wild fires enhanced by GW (reducing or cutting short their uptake of CO2 & releasing CO2 in the process) 3) ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more heat 6) the warming slowing the thermohaline ocean conveyor & its up - churning of nutrients — reducing marine plant life & that carbon sink.

None of the sea - ice specialists I've interviewed since 2000 on Arctic trends ever predicted a straight - line path to an open - water Arctic, but quite a few have stressed the longstanding idea that as white ice retreats, solar energy that would have been reflected back into space is absorbed by the dark sea, with that heat then melting existing ice and shortening the winter frozen season.

As Arctic sea - ice shrinks, energy from the sun that would have been reflected away by sea - ice is instead absorbed by the ocean.
