Decisions made there will determine whether our children will inherit a changed-but-recognizable ocean that still provides humanity with goods and services, or a damaged ocean lacking many resources we want.

Coral reefs are under assault. Overfishing and coastal development are partly to blame, but ocean acidification is an emerging threat to corals and a host of other species that rely on calcium carbonate for their shells. As CO2 increases in the atmosphere, it dissolves in the ocean and it is changing the very chemistry of the sea.

And it’s happening now.  Continue reading »
