Significant Warming of the Antarctic Winter Troposphere

The "iconic" Antarctic temperature trends are the large warming seen on the Antarctic Peninsula, which has had various repercussions including the collapse of several ice shelves (some documented in a previous post). Elsewhere, though, the pattern of surface warming is more complex - trends are smaller, and while more are positive than negative they are generally not significant - see this map. Contrary to what you might have heard, this is in general agreement with model predictions.
