One other factor here is increased evaporation at the equator which has increased the salanity of tropical waters along with increased percipitation at the poles seems to be making the thermohaline system move faster which in turn carries move heat to the poles and hence increases polar ice melting and hence possibly a greater chance of slowdown of the thermohaline system.

Although there is still some disagreement in the preliminary results (eg the description of polar ice caps), a lot of things appear to be quite robust as the climate models for instance indicate consistent patterns of surface warming and rainfall trends: the models tend to agree on a stronger warming in the Arctic and stronger precipitation changes in the Topics (see crude examples for the SRES A1b scenarios given in Figures 1 & 2; Note, the degrees of freedom varies with latitude, so that the uncertainty of these estimates are greater near the poles).

Sea ice loss from climate change is causing polar bears to swim longer distances to find stable ice or to reach land, resulting in greater risk to their cubs, according to a new paper co-authored by a WWF expert.

However, the recovery plan does not tackle the greatest adversary experienced by the polar bears, the rapid decline of sea ice due to the warming climate.

It was the warming of the polar ice caps that became the greatest concern, since this was the first tangible evidence, and will have the biggest initial impact upon coastal cities and low lying countries.

Rapidly rising seas resulting from melting glaciers as well as polar ice sheet nearly wiped out the Great Barrier Reef some 125,000 years earlier, according to University of Sydney researchers.

Today, I'll take a look at sea ice and ringed seal habitat in the Gulf of Boothia and M'Clintock Channel, as well as information from a study on polar bear diets, which together shine some light on why the Gulf of Boothia is such a great place for polar bears.

Mars undergoes temperature swings influenced by how much sunlight reaches the surface, which also affects its polar ice caps (another great influence on the atmosphere.)

What these observation ssuggest ot me is the sun's radiation has a greater role in the disappearance of glaciers and polar ice caps that does CO2.

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).

During this past summer's rollout of the EPA's historic climate initiative, the president and his allies went to great lengths to reframe the climate change debate around the health of our children and the elderly, as opposed to the fate of the polar bears and the melting ice caps that have long served as the de facto mascots of the climate movement.

For more than two decades, meteorologists and oceanographers have repeatedly warned that runaway global warming, as a consequence of ever - greater combustion of fossil fuels, could bring about an ice - free polar ocean by about 2050.

Warmer oceans lead to great heat being advected via ocean currents to the polar regions, leading to more ice loss and general warming.

As sea ice thins, and becomes more fractured and labile, it is likely to move more in response to winds and currents so that polar bears will need to walk or swim more and thus use greater amounts of energy to maintain contact with the remaining preferred habitats.

As the ice melts and Arctic temperatures warm, polar bears are forced to find new habitat (usually farther south, where the humans also live in greater numbers).
