Gone south: the global fallout of a melting Antarctica

Earth’s southern pole has traditionally been neglected in the narrative around climate change, partly because scientists used to think that Antarctica was a relatively stable place. Their models, it turns out, were wrong. Some jaw-dropping events and extremes in recent years have shown that Antarctica is undergoing massive changes on land, sea and in the atmosphere. As a result, a new portrait of the continent is emerging which has, so far, received little attention. Polar scientists are warning of a “regime shift”.
