This is not new. Antarctica has been assumed to not be a problem for the
reasons above (and others such as the currents that isolate the continent).
What this new study shows is that assumption may be wrong. Over 150
subsurface lakes have been recently discovered primarily under the parts of
the ice that are thinning due to warming. The IPCC prediction here is based
on models that are known not to be accurate and further they don't include
this phenomenon. Net net, the IPCC may be giving false comfort with respect
to Antarctica. We will have to wait and see what the models look like when
this effect is factored in.
