There is (however) no significant delay in the Anarctica climate anomaly...

The layers in multi-year ice (mainly formed when sheets of thin first - year ice pancake) do help baby seals, but polar bears happily walk on first - year ice thin enough to see through (don't take my word for it; watch the film Arctic Tale).

Re 42 Gavin, it seem we have to wait a bit more to see polar ice sheets growing for more heat when yr models have continuously overestimated polar amplification, please see:

Determining whether polar ice sheets are shrinking or growing, and what their contribution to changes in sea level is, has motivated polar scientists for decades.

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 equilibrium referred to is that of the ocean — it doesn't include very slow changes in polar ice sheets, etc.) Obviously, the upper tail of the estimated distribution for S is important, not just its central value.

Which experts on sea level rise, ice sheet dynamics, and polar bear biology / ecology did you contact for your articles on polar bear populations and sea level rise?

The Greenland ice sheet is poised for another record melt this year, and is approaching a «tipping point» into a new and more dangerous melt regime in which the summer melt area covers the entire land mass, according to new findings from polar researchers.

The only comprehensive study of the Antarctic Ice Sheet mass was a 10 + year study based on continuous 24/365 satellite measurements over the period 1993 to 2003, covering 80 % of the AIS with estimates from other methods for the remaining 20 %, which can not be measured by satellites (coastal areas and polar regions).

Although the satellites are considered the gold - standard for measuring and observing sea levels, hurricanes / typhoons, ozone holes, sea ice, atmospheric CO2 distribution, polar ice sheet masses and etc., the same 24/7 technology used to measure temperatures across the entire habitable world is now being ignored (i.e., denied) due to the above inconvenient evidence.

Rather, it both offers a tool for exploring the sea level implications of polar ice sheets» complex physical responses to global warming and highlights the deep uncertainty that characterizes sea level change in a high - emissions future.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

Based on what he's seen in the Arctic, and on the latest science, Zukunft said he's planning for six feet of sea level rise by the end of the century, as polar ice sheets and glaciers melt.

Instead of fixing the black carbon (soot) pollution they are responsible for, the EU activists continue to rail about the atmospheric trace gas CO2, which, by the way, doesn't melt glaciers, sea ice or polar ice sheet caps.

A finding which is supported by a just - published paper showing the polar ice sheets are retreating in a synchronous manner for the first time, which puts the current warming into context.

And of course, the future fate of the ice sheets and how they will dynamically respond to climate warming is hugely important for projections of sea level rise and polar hydrology.

A major limitation is the fact that the calibration phase for these semi-empirical models does not cover the range of climate - system behaviour that might be expected for the 21st century, i.e., significant loss of ice from the large polar ice sheets.
