From my article :

Some of the regions in which GRACE claims ice loss in East Antarctica average colder than -30°C during the summer, and never, ever get above freezing. How can you melt ice at those temperatures?

How did John Cook respond? He posted a lengthy three part straw man “rebuttal” discussing movement of glaciers near the coast, where temperatures are warmer. Which obviously was not what I was referring to.

Belief in AGW seems to be driven by comprehension problems.
