Fourth global mass bleaching of coral reefs underway. More than 54 percent of the world’s coral area has experienced bleaching-level heat stress in the past year, and that number is increasing by about 1 percent per week, says NOAA's Coral Reef Watch scientist Dr. Manzello.
#GreatBarrierReef in Australia is suffering what appears to be its most severe #CoralBleaching event; about a third of the reefs surveyed by air showed prevalence of very high or extreme bleaching, and at least three quarters showed some bleaching.
“Every year about 134 million atomic bombs of heat is being trapped by the ocean. It has kept global temperatures down and kept the land livable but we have to realise that energy hasn’t gone.”
