The Washington Post reports: Scientists have known for some time that when global warming occurs, the oceans will be the site of the most profound response.
The reason is simply that they are able to retain vastly more heat than the atmosphere. “Ninety, perhaps 95 percent of the accumulated heat is in the oceans,” said Peter Gleckler, an oceanographer at the Lawrence Livermore National Laboratory. The physical reason is that water has a far greater heat “capacity” than air, requiring more energy to raise its temperature — something that is apparent to anyone who has ever tried to boil it on a stove.
Gleckler is the lead author of a new study in the journal Nature Climate Change finding that, in the past two decades, ocean heat content has been rising rapidly and that, much more than before, heat is also mixing into the deeper layers of the ocean, rather than remaining near the surface.
