Watch “The Deadliest Catch” … all that crab comes from the Bering Sea. Not much coral up there. And your lobster comes from around the Grand Banks.Well of course that is assuming that global climate change wonlt end up in much cooler temperatures for the northern hemisphere. As for Crab and Lobster…I wouldn;t bet on that. See much of the carbon dioxide that we put into the atmosphere about 22 million tons a day and climbing according to an article I read in Discover Magazine Now this is changing the basic ph of the ocean. According to this article according to ice cores the oceans had a ph of about 8.2 for 600,000 years. This has dropped by 0.1 unit. Now I know most people are probably at this point thinking wow gee a whole 0.1 change!But apparently since ph is measured on the logarithmic scale this is actually a 30% increase in acidity. Also apparently according to a dozen predictions from the international panel on climate change by the end of the century the ph could drop as low as 7.8 a 150% increase since preindustrial times. Long story short low alot of things in the oceans are in deep deep trouble. Coral and the stuff that they secrete that form the coral reefs are in big trouble…heck anything with a shell is in trouble. That means crab, clam, lobster, plankton as well as other things. Then it isn; a big leap to go from realizing that if the things on the lower end of the food chain start dying off then the things that eat them are in trouble too. So that means things like otters, seals, the whales, as well as many of the fish that we eat are in trouble as well. Not to mention in the polar and subpolar regiions of the ocean these things called pteropods are at risk. These things are a food source for Salmon, herring, cod and pollack. And according to the article the berring sea a artic/sub artic part of the ocean supports about 30% of the global harvest of sea food. The program deadliest catch seems to take for the most place here. A couple more sources I found here ioc3.unesco.org/oanet/FAQacidity.html dailyclimate.org/topics/ocean-acidification
Long story short I wouldn;t count on more crab or lobster or more of most/any kind of edible fish.
Many of these critters are a billion years old and have survived all sorts of devastation. Somehow I don’t think that a one degree per century change in temp is going to make much difference.
Africa was under water at one point (as was Montana). And the Sahara Forest had lakes and trees.
