Here's a study released in March of 2007. The headline says Regardless of global warming, rising CO2 levels threaten marine life. The logic is difficult to follow: The article states

* Ocean acidity is rising as sea water absorbs more carbon dioxide released into the atmosphere from power plants and automobiles. The higher acidity threatens marine life, including corals and shellfish...

* The ocean-surface pH has been reduced by about 0.1 during the past two centuries (It has gotten more acidic.)

* During the last 200 years, the concentration of atmospheric carbon dioxide increased from about 275 parts per million to about 380 parts per million. Unchecked, it could surpass 550 parts per million by mid-century.

* "Warmer water...directly reduces the ocean pH...(makes it more acidic)

* warmer water also absorbs less carbon dioxide, which makes the ocean less acidic.

* future changes in ocean acidity caused by atmospheric carbon-dioxide concentrations are largely independent of climate change."

Now if the warming starts first, then CO2 starts to rise, less CO2 is absorbed into the water and more stays in the atmosphere which according to some scientists is a greenhouse gas, causing more warming and less CO2 absorption in the water. I would think, therefore, a warmer ocean would be good for corals and shellfish.

Tell me again about the theory of Global Warming!
