Corals can bounce back from bleaching, if humans don't ruin it: study

Some corals can recover from bleaching even in long heatwaves as long as humans don't interfere, scientists said Tuesday, raising hopes for the endangered underwater ecosystems essential to much marine life.

Researchers tracked corals of the Kiritimati atoll in the Pacific Ocean through the longest tropical heatwave on record, expecting the reefs to suffer mass bleaching.
