I don´t want to be a negative thinking guy, but I think we must read this article!
Ocean may be losing ability to soak CO2 ...
WASHINGTON May 17/2007 - The ocean, which has absorbed some excess carbon dioxide from the atmosphere for centuries, may be losing that ability, a new report says.
The buildup of carbon dioxide in the air since the beginning of the industrial revolution has raised concerns that it would trap solar energy and cause a warming of the climate. The oceans are believed to absorb about one-quarter of human-related carbon emissions.
But researchers reporting in the journal Science say at least one large ocean area — the Southern Ocean that surrounds Antarctica — seems to be losing its ability to take up the gas.
Their four-year study concluded that an increase in winds over the Southern Ocean is preventing it from absorbing more carbon and is causing the sea to release some of the gas that it had stored.
"This is serious. All climate models predict that this kind of 'feedback' will continue and intensify during this century," lead author Corinne Le Quere of the University of East Anglia said in a statement.
In addition to East Anglia, researchers participating in the study were from the British Antarctic Survey and the Max-Planck Institute for Biogeochemistry in Jena, Germany.
I read a New Yorker article about this last year, its been known for quite some time. The ocean's ph is changing because of the amount of carbon being absorbed. I think it said by 2075 most coral reef systems could be gone.

Yet on the other hand, higher co2 levels would also create higher levels of calcium...therefore encouraging hard coral growth

Yeah except the change in acidity of the water affects algae that grow on the coral and allow it to survive, although I cant remember specifics. The article in fact had a section where they talked about an experiment at what was once the "bio-dome" in arizona where a scientist took over the coral reefs, and couldn't understand why they kept dying.
Good article, if I can look up what issue it was in, i'll post it.

The science isn't all in yet, we shouldn't take this too seriously

... CO2 levels have been higher many times in the past.
I really don't think anyone ever think logically about... well anything, look how BIG the ocean is.
Plus the environmentalists are saying we are now putting so much CO2 in the the AIR to cause "global warming" AND in the oceans to saturate it? Give me a break
PS - C02 does not cause change in temperature, Temperature causes changes in CO2, thats why the "models" fit together from Al Gores show.

I'm basing my logic on the writtings of scientists who specialize in what they do. Not how "big" I think something is.
It is big, but how many tons of CO2 do we create per day?

The algae you mention is the symbiotic zooxanthellae that lives Within the corals. Sunlight feeds the algae which inturn feeds the coral. Being that zooxanthellae algae is an ancient single celled life form it spreads and adapts very quickly so i think they could withstand climate change better than other species.
