Posted Thu Dec 11 2008: from Mongabay:
Climate change will transform the chemical makeup of the ocean
"The ocean's calcium cycle is closely linked to atmospheric carbon dioxide and the processes that control seawater's acidity," co-author of the paper, Ken Caldeira, adds. Already, increasing acidification of the ocean is decimating certain populations of coral. In past research Caldeira has pointed out that an increasingly acidic ocean will doom the world's fishing industry and degrade 98 percent of the world's coral reefs in less than fifty years.... "as CO2 increases and weather patterns shift, the chemical composition of our rivers will change, and this will affect the oceans. This will change the amount of calcium and other elements in ocean salts." "What we learned from this work is that the ocean system is much more sensitive to climate change than we have previously appreciated," Griffith adds.

At least nothing in the ocean depends on calcium! Whew!
