The warming trend nevertheless is unexplained. No, not by BAS scientists who prefer to call the warming in the Antarctic Peninsula a strong regional warming. They say this because no Global Circulation Model predicts that the region should be oversensitive to changes in greenhouse forcing. However this could be just a failing of the current suite of Global Circulation Models which one could argue are not detailed enough to simulate the climate of the region. The GCMs all differ in their predictions of the pattern of change expected in the Antarctic next century.
None predict an unusually high warming localised in the Antarctic Peninsula.
He failed to comment that the majority of Antarctica has had a stable climate this century. Yes, but only in the Antarctic Peninsula. This is the region that has warmed by 2.5 degrees Centigrade since 1940, and is the one region of the Antarctic where summer temperatures exceed 0 Degrees Centigrade. The infilitration of melt water is seen as an important element in the disintegration of ice shelves. Thus, the most northerly ice shelves existing today are at risk from irreversible disintegration.
