On October 19, 2018, Nick Bond, a University of Washington atmospheric scientist, said that sea surface temperatures across thousands of miles of the North Pacific and Gulf of Alaska are now up to 3 degrees Celsius warmer than normal, "which is quite a bit." A ridge of high pressure is keeping skies warm and dry, allowing heat to build up. And these new estimates line up with climate models, adding heft to their predictions, which show ocean warming accelerating even faster in the future. So far, because the oceans are vast, the baseline temperature of the water has shifted upward by only a fraction of a degree, but even that seemingly slight change has affected weather patterns, marine life, and sea levels around the world. On January 10, 2019, a group of scientists reported in the journal Science that the world’s oceans nearly doubled the amount of heat they absorbed from the atmosphere-about 93 percent of all extra heat from climate change, and faster than previously thought. This story appears in the September 2016 issue of National Geographic magazine. ![]()
