More Ocean Productivity Decline

By Oceans

A study in Science on the 13th shows a 12% average decline in ocean productivity along the western Antarctic Peninsula in the last 30 years. Temperatures have increased here 4.6 times the global average. In the last few years of the study (beginning about the time the Big Melt began in Greenland – about 2004)…
