According to the National Oceanic and Atmospheric Association, roughly 75% of the world's tropical coral reefs experienced severe enough heat to trigger bleaching between 2014 and 2017. It is a global phenomenon, with just 2% of Indo-Pacific reefs containing as much live coral as they did in the 1980s. [2]
The coral is believed to be several centuries old, and is “so colossal that it can be seen from space,” the National Geographic Pristine Seas team behind the discovery said. It is almost three ...
