Loss of Antarctic ice could trigger super-interglacial

New Scientist: At least eight times in the last 2.8 million years, the Arctic experienced super-interglacials - periods in which summers there were 5 °C warmer than they are today. Climate models cannot explain these unusually warm spells, but there could be an unexpected cause: the collapse of the West Antarctic ice sheet (WAIS), on the other side of the planet.
