1. "The increased C2 is coming out of sea water . . . " Uh, no. It's being absorbed by sea water, hence the drop in pH for the Pacific Ocean - that's the entire Pacific Ocean - of 0.026 in the space of a little more than a decade. IOW, an increase of about 25% in acidity in a geological eyeblink.

Ever hear of the Permian Extinction? You know, the one that wiped out about 90% of life then on Earth? I didn't really think so, but here, let me assist you:
"To solve the puzzle of how those conditions may have affected climate and life around the globe, the researchers turned to the Community Climate System Model (CCSM). One of the world's premier climate research tools, the model can integrate changes in atmospheric temperatures with ocean temperatures and currents. Research teams had previously studied the Permian extinction with more limited computer models that focused on a single component of Earth's climate system, such as the ocean.
The CCSM indicated that ocean waters warmed significantly at higher latitudes because of rising atmospheric levels of carbon dioxide (CO2), a greenhouse gas. The warming reached a depth of about 10,000 feet (4,000 meters), interfering with the normal circulation process in which colder surface water descends, taking oxygen and nutrients deep into the ocean.
As a result, ocean waters became stratified with little oxygen, a condition that proved deadly to marine life. This in turn accelerated the warming, since marine organisms were no longer removing carbon dioxide from the atmosphere.
"The implication of our study is that elevated CO2 is sufficient to lead to inhospitable conditions for marine life and excessively high temperatures over land would contribute to the demise of terrestrial life," the authors concluded in the article."

Here's a little primer from the American Institute of Physics. Or are they not politically reliable enough to suit you?
