Global Coral Bleaching Update — Pacific Corals, Seychelles in Danger as Great Barrier Reef Cools

robertscribbler

The last global coral bleaching event that inflicted a degree of damage comparable to the one we are now experiencing occurred during 1997 through 1999. Back then, global annual surface temperatures hit a peak of 0.85 degrees Celsius hotter than 1880s averages and ocean temperatures in many regions hit a range of 29-30 C or more. This warming-spurred event generated never-before seen wreckage among the world’s corals.

(Pacific Ocean sea surface temperatures are again warming as the Equatorial region progresses toward a predicted 2017 El Nino. Sea surface temperature anomalies of 1-2 C above average are now very widespread with embedded hot spots that contain 2-4 C above average temperatures [see above map]. These anomalies are enough to continue a global coral bleaching event that has now lasted for four years. Image source: Earth Nullschool.)

  1. I read somewhere that the coral reefs serve as nurseries for many smaller fish that are then food for bigger fish that are caught for human consumption. Without healthy coral the ocean will not be hospitable for the cycle of life of small fish. There is assault on the fish by humans in more ways than one, by dredging the deep water by commercial fishing fleet, by changing of the climate which changes the temperature of the water and by pollution, all contributing to destruction of the coral reef.
