Scientists: Global warming has already changed oceans http://apocadocs.com/s.pl?1244662241
In Washington state, oysters in some areas haven't reproduced for four years, and preliminary evidence suggests that the increasing acidity of the ocean could be the cause. In the Gulf of Mexico, falling oxygen levels in the water have forced shrimp to migrate elsewhere.... Federal studies also found acidity levels in the North Pacific and off Alaska are unusually high compared to other ocean regions. The high acidity is already taking a toll of such tiny species as pteropods, which are an important food for salmon and other fish.
As greenhouse gas emissions increase, billions of tons of carbon dioxide from smokestacks and vehicle tailpipes are absorbed by the oceans. The result is carbonic acid, which dilutes the "rich soup" of calcium carbonate in the seawater that many species, especially on the low end of the food chain, thrive in...
