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).

of uncertainty about the
amount of warming and interactions between
various parts
of the environment, and we should have started to take action to reduce our emissions».

Looks to me like the much simpler argument that CO2 is a greenhouse gas; greenhouse gases enhance atmospheric
warming; enormous

of fossil fuels; and according to
various measurements, the temperature
of the atmosphere appears to be steadily increasing as a result.
