Coral reefs with high ecological integrity are able to quickly recover from extreme climate impacts. In our new study in Coral Reefs, we found high integrity Fiji reefs were able to rebound rapidly following a category 5 cyclone.

There is still hope to save irreplaceable coral ecosystems, but time is running out. Baby corals can ride ocean currents for hundreds of miles, but they can’t outrun climate change. And humans have a limited capacity to make new reefs in cooler waters. buff.ly/nY4jJs0 #WorldOceanDay
Coral reefs face an uncertain recovery from the 4th global mass bleaching event – can climate refuges help?
As baby corals float in the currents, they can expand their species’ range. But can they get to climate refuges fast enough to survive? A new study has good news and bad.
