Major Report
CO2, Global Warming and Coral Reefs: Prospects for the Future: The ongoing rise in the air's CO2 content has been predicted to play havoc with earth's coral reefs in two different ways: (1) by stimulating global warming, which has been predicted to dramatically enhance coral bleaching, and (2) by lowering the calcium carbonate saturation state of seawater, which has been predicted to reduce coral calcification rates. We evaluate the likelihood of such claims in a new major review paper.
