Ocean Acidification and Temperatures

I believe this subject merits a section of its own for the following reasons

1. Oceans have become more acid than at any time in the last 35 million years
2. Processes in the ocean are much less well understood than those on land. For example there are thousands of calcifying organisms on earth and we have investigated only six to ten of them.
3. Half the photosynthesis on earth takes place in the ocean.
4. Nearly half the excess CO2 we produce is absorbed in the ocean
5. Dissolved CO2 in the oceans quenches life and changes behaveour.
6. Some shells are 33% thinner than 1970's already 

A good summary of the dangers is given in this NOAA lecture.
