Great Barrier Reef affected in 3rd mass coral bleaching in just 5 years!
In the last 5 years, for the 3rd time, the Great Barrier Reef is witnessing a mass coral bleaching. The scientists said that after 3 days of observation, they feel that it is severe bleaching and they will get a full picture after a full 9-days long survey. Greenhouse gases have caused global heating and the coral reefs are facing huge threats due to that. Not all bleach corals die, but it is a great threat, indeed.
