It also eliminates much
of the uncertainty surrounding potentially ill effects; whereas
various mathematical models may disagree about when and at what concentrations Arctic Ocean sea ice disappears, they all agree that at roughly 3
degrees C
of warming, the far north will be ice - free.
Apart from these last concerns, the WAIS is much less worrying than the GIS, because the huge thermal inertia and albedo effect
of the EAIS, the antarctic continent itself, and the large amount
of antarctic sea ice in the southern winter, all act to reduce the
degree of warming for the WAIS (whereas the GIS is the victim
of various unfortunate circumstances which amplify
warming there).

warming scenarios.
Mark Lynas's «Six
