Climate Change And Coral Reefs

The Atlantic highlights 5 charts demonstrating the threat of climate change.  This one is notable to me:

3. Coral reefs are doomed

Coral reefs, which protect against coastal flooding, storm surges, wave damage, and also provide homes for lots of fish, are doomed on our current course, says the World Bank. Coral reefs are dissolving because of ocean acidification--the more CO2 in the atmosphere, the more gets dissolved in the oceans. The illustration shows the impact on coral reefs at various CO2 levels. Coral reefs may stop growing as CO2 concentration levels approach 450 ppm, which is expected over the coming decades. By the time the concentration reaches around 550 ppm in the 2060s, coral reefs will start to dissolve.

That is a lot of ocean diversity of species at risk.  It is just a really bad sign for our future.
