Over the past year, several studies about highly dangerous signals of Antarctica on the edge of major abrupt change have appeared in scholarly publications. These studies in premier publications expose rapid changes, e.g. (1) discovery of the western Antarctic Peninsula as one of the fastest warming places on Earth (2) ocean currents threaten to collapse Antarctic Ice Shelves (3) present day mass loss rates are a precursor for West Antarctic Ice Sheet collapse (4) an unexpected ice collapse hints at worrying changes on the Antarctic coast. The new scientific narrative has scientists very nervous.

Abrupt changes have become more common in the climate system, but Antarctica is one region that nobody wants to hear about “abrupt change,” especially with the potential impact nearly impossible to analyze with certainty.
