To paraphrase the astronomer Neil DeGrasse Tyson, climate change exists whether you believe it or not. And it’s not pretty.
Latest example: According to this article in the New York Times, as oceans warm, fish populations are declining. The amount of seafood that humans could sustainably harvest from a wide range of species shrank by 4.1 percent from 1930 to 2010, a casualty of human-caused climate change. That four percent decline works out to 1.4 million metric tons of fish from 1930 to 2010. And in the northeast Atlantic Ocean and the Sea of Japan, fish populations declined by as much as 35 percent over the period of the study.
Fish make up 17 percent of the global population’s intake of animal protein, and as much as 70 percent for people living in some coastal and island countries. 56 million people worldwide are supported in some way by marine fisheries.
