CO2 is healthy for the vegetation, all the plants rely on it so what the hell? I am all for saving the planet, not polluting environment, not using rivers for waste dumps, saving endangered species etc... but CO2 is just silly. Even if global warming was harmful (I don't know), CO2 is a very minor greenhouse effect gas, and human produced CO2 is even less significant.

well, thanks to humans the ammount of co2 in the air has increased by 20% over the last 50 years
and thats a hell of a lot of co2

and to quote wikipedia:
NOAA states in their May 2008 "State of the science fact sheet for ocean acidification" that:
"The oceans have absorbed about 50% of the carbon dioxide (CO2) released from the burning of fossil fuels, resulting in chemical reactions that lower ocean pH. This has caused an increase in hydrogen ion (acidity) of about 30% since the start of the industrial age through a process known as “ocean acidification.” A growing number of studies have demonstrated adverse impacts on marine organisms, including:

The rate at which reef-building corals produce their skeletons decreases, while production of numerous varieties of jellyfish increases.
The ability of marine algae and free-swimming zooplankton to maintain protective shells is reduced.
The survival of larval marine species, including commercial fish and shellfish, is reduced."

Thanks for bringing up other effects of CO2 increase. I do not believe in it contributing to the global temperature in a serious matter (quite the opposite, temperature increase, increases CO2 natural production) but it might affect life in other ways, possibly harmful as you have pointed out.

http://dangerousintersection.org/wp-content/uploads/2006/09/CO2-Tem... This is often pointed out as a proof of CO2/temperature relationship. Careful examination shows that it's the CO2 that lags after temperature.

You obviously don't know any chemistry because the treat of acidification is exactly zero. It is literally impossible:

- pH is logartithmic. In other words a pH of 6 is 10x as acidic as a pH of 7.

- Carbonic acid (dissolved CO2) is weak acid. A 30% increase in dissolved CO2 has negligible impact on the pH of seawater.

- pH is highly temperature sensitive. The pH of seawater changes far more in due to temperature changes than atmospheric CO2 levels.

- seawater cannot become acidified (or significantly less basic) by CO2 because it is heavily buffered by dissolved salts.

- Ocean acidification has never occurred even with CO2 concentrations 20x as high as present.
