Ice sheets across the Himalayas have shrunk 10 times faster in the past four decades than during the previous seven centuries. The rapid ice melt threatens agriculture and water supply for millions of people in South Asia, according to research published Monday in the journal Scientific Reports. There is scientific consensus that human-caused climate change has resulted in accelerated ice melt from glaciers and higher ocean temperatures across the world. - CNBC

A significant part of the Greenland ice sheet is on the brink of a tipping point, after which accelerated melting would become inevitable even if global heating was halted, according to new research.  Rising temperatures caused by the climate crisis have already seen trillions of tonnes of Greenland’s ice pour into the ocean. Melting its ice sheet completely would eventually raise global sea level by 7 metres.  The new analysis detected the warning signals of a tipping point in a 140-year record of ice-sheet height and melting rates in the Jakobshavn basin, one of the five biggest basins in Greenland and the fastest-melting. The prime suspect for a surge in melting is a vicious circle in which melting reduces the height of the ice sheet, exposing it to the warmer air found at lower altitudes, which causes further melting. - Guardian
