Coral Bleaching - Nemo's Home is Not Suppose to be White

Over 93% of the Great Barrier Reef is bleached.  This has been caused by increased water temperatures.  The current spike in global heat can be partly explained by natural variability and the monster El Nino event now ebbing in the Pacific, humans have contributed about 1.25 degrees or more of global warming since pre-industrial times.  

If the water temperatures quickly gets back to normal the coral will come back to life in all of its colours. The risk is between the bleaching and returning back to health that algae and other underwater predators like the Crown of Thornes can kill the coral for good.
