New paper in PNAS, "Temperature-dependent feedbacks drive the pattern of Antarctic temperature change", by Brad Markle and me, where we show that a simple but largely-overlooked non-linearity in the greenhouse effect at cold temperatures explains most of the differences among different Antarctic ice core records. The small residual differences readily explained by elevation change. Based on this, we provide a revised estimate of elevation change at WAIS Divide, which agrees with independent geological constraints.
