Part of the problem with coral is that the oceans are becoming more acidic, and as a result, it literally dissolves coral skeletons.

- mythrwy 7y agoI can see acidification being an issue for sure. And CO2 is supposed to increase acidification. But many geological reef formations are very old, 10's or even hundreds of millions of years old. At the time these reefs were formed, CO2 levels were much much higher than they are predicted to be any time soon. Yet somehow the reefs were constructed anyway and corals as a species pulled through. In spite of CO2 levels (per Wikipedia) '''between 200 and 150 million years ago of over 3,000 ppm, and between 600 and 400 million years ago of over 6,000 ppm''' (what are we at today? like 400ppm?) The reef I live on incidentally is thought to have been formed like 265 million years ago. At which time CO2 levels were possibly an order of magnitude higher than today. So I really am a bit confused still.
