Glaciologists at the Royal Society in London, this week have busted the four-year-old claim that Antarctica would not contribute significantly to sea level rise in the 21st century. They claim that the ice continent could already be dominating the causes of sea-level risings. Crumbling at an unprecedented rate, the glaciers from the Antarctica ice sheets are dumping more than 110 cubic kilometers of ice each year. Warm ocean waters are circulating beneath the Pine Island and Thwaites glaciers. These currents are melting their bases, triggering an ever-faster slide into the ocean. The two glaciers are simultaneously discharging ice three times faster compared a decade ago. Once they disappear completely they would alone raise sea levels worldwide by more than a meter.
