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

Sea ice and snow cover melt, turning brilliant white reflectors of sunlight into darker spots.

Not surprisingly, the Arctic ice and snow cover are responding with record low extents.

Land comprises only about 30 % of the Earth's surface, but it can have the largest effects on the reflection of global solar radiation in conjunction with changes in ice and snow cover, and the shading of the latter by vegetation.

The Arctic is warming twice as fast as the rest of the planet, for reasons that may include its layered atmosphere, which traps heat, and the loss of sea ice and snow cover, which when present help reflect the sun's energy.

Considerable effort should be made to estimate thickness distributions of ice and snow cover needed to initialize simulations.

Yet some kind of climate model is indispensable to make future predictions of the climate system and IPCC has identified several reasons for respect in the climate models including the fact that models are getting better in predicting what monitoring evidence is actually observing around the world in regard to temperature, ice and snow cover, droughts and floods, and sea level rise among other things.

Add a dramatic increase of CO2 and methane emissions to the albedo declines of sped up Arctic ice and snow cover losses and you may still witness a runaway situation.

One reason I suspect this happened is because decreasing ice and snow cover increased the lapse rate overall in the lowest ~ 1 - 1.5 kilometers of the lower troposphere.

Maue discussed how «two camps» of researchers claim to have increased predictability of such weather events over periods of a month or more by using clues either in the Arctic, related to the extent of sea ice and snow cover, or in the temperature of surface waters across the Pacific Ocean.

The study marks the first time that human influence on the climate has been demonstrated in the water cycle, and outside the bounds of typical physical responses such as warming deep ocean and sea surface temperatures or diminishing sea ice and snow cover extent.

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.
