That it is possible to construct a metric that doesn't show regional warming in a certain roughly specified region on a certain unspecified time scale with a certain unspecified statistical technique in no way contradicts the assertion that the balance of observational evidence shows unusual recent global warming, in first order agreement with theoretical, computational, and paleoclimate evidence.

Therefore and in flagrant contradiction with Steig et al. 2009, catabatic winds and anticyclones coming out of Antarctica are stronger - in fact more snow precipitation there - thus regional warm air advections directed by the relief will also be stronger.
