Climate Change Is Causing The Dissolved Oxygen In World’s Oceans To Plummet

A new analysis of nearly five decades of data has now revealed how this inexorable rise in ocean temperatures has affected the oxygen dissolved in it. The analysis, published in the latest edition of Geophysical Research Letters, shows that dissolved oxygen levels started dropping in the 1980s as ocean temperatures began to climb.Read: The Curious Case Of The Global Warming ‘Hiatus’Between then and now, the upper ocean “oxygen inventory” dropped at rate of 243 teramole per decade. This drop in dissolved oxygen, in turn, has led to a rise in hypoxic events in recent years, wherein low or depleted oxygen in oceans leads to the creation of “dead zones” that can no longer sustain populations of fish, corals, crabs and other marine organisms.
