Melting Greenland glacier water
forms a "slow wave" that stays in the Atlantic for at least 50 years before reaching the Pacific, according to a new study. The water piles up in the Atlantic. "It is often assumed that sea levels will rise instantaneously, but that is unlikely, given what we know about ocean dynamics." Fifty years after the meltwater is released from Greenland, sea-level rise could be 30 times greater around Greenland and down the eastern side of North America, including the Gulf of Mexico, than in the Pacific Ocean. Sea-level rises in Europe are around six times that of the Pacific, but only a fifth as great as on the opposite shore of the Atlantic.

Global warming approaching point of no return...
Climate change: report warns point of no return may be reached in 10 years, leading to droughts, agricultural failure and water shortages. The possibilities include reaching climatic tipping points leading, for example, to the loss of the West Antarctic and Greenland ice sheets (which, between them, could raise sea level more than 10 metres over the space of a few centuries), the shutdown of the thermohaline ocean circulation (and, with it, the Gulf Stream), and the transformation of the planet's forests and soils from a net sink of carbon to a net source of carbon. Countdown to global catastrophe
