Coral reefs: Keeping up with sea-level rise

A recent study by the Palau International Coral Reef Centre has shown that Palau’s coral reefs can keep up with projected sea-level rise if ocean temperatures do not rise too quickly, reefs are locally maintained, and atmospheric CO2 levels stay below 670 ppm (currently over 400 ppm). Beyond 670 ppm, even healthy reefs will not be able keep up with sea-level rise.
