The new figures are in the IPCC's numbers.
And those numbers are?
Big ice sheets are sort of invulnerable to warm air blowing over them. The air will be at zero c by the time it has gone 100m across them so the rest of the ice can only be heated by the suns radient energy. Given we are at the distance away from the sun we are and that almost all of the IR is reflected there is a very slow melt rate of ice. See sunbathers in the Alps sitting on glaciers and ice pockets.
I was simply saying that how fast the ice melts is a function of the temperature that is not limited. As we pump more and more CO2 into the atmosphere the greenhouse gas effect will change the amount of IR that is reflected and raise the temperature.
