Highlighting seas that are rising at an accelerating rate, especially in the far more vulnerable Pacific island nations, U.N. Secretary-General Antonio Guterres issued yet another climate SOS to the world. This time he said those initials stand for “save our seas.” The United Nations and the World Meteorological Organization Monday issued reports on worsening sea level rise, turbocharged by a warming Earth and melting ice sheets and glaciers. They highlight how the Southwestern Pacific is not only hurt by the rising oceans, but by other climate change effects of ocean acidification and marine heat waves. Guterres toured Samoa and Tonga and made his climate plea from Tonga’s capital on Tuesday at a meeting of the Pacific Islands Forum, whose member countries are among those most impe...

How coastal ocean currents increase Antarctic ice shelf melt A new model developed by Caltech and JPL researchers suggests that Antarctica's ice shelves may be melting at an accelerated rate, which could eventually contribute to more rapid sea level rise. The model accounts for an often-overlooked narrow ocean current along the Antarctic coast and simulates how rapidly flowing freshwater, melted from the ice shelves, can trap dense warm ocean water at the base of the ice, causing it to warm and melt even more. The study was conducted in the laboratory of Andy Thompson, professor of environmental science and engineering, and appears in the journal Science Advances on August 12.
