Australia's Great Barrier Reef hit by record bleaching

> Australia's spectacular Great Barrier Reef is experiencing its worst #bleaching event on record, the country's reef authority reported on Wednesday (Apr 17).

> Often dubbed the world's largest living structure, the Great Barrier Reef is a 2,300km-long expanse, home to a stunning array of biodiversity including more than 600 types of coral and 1,625 fish species.

Probably the worst #coral #bleaching on record is now killing a 1400-mil long stretch on the #GreatBarrierReef. This is caused by off-the-charts levels of ocean heat thanks to human-caused #ClimateChange.

"There is no evidence of mass bleaching occurring before 1998 but, since an episode that year, marine heat waves have returned with increasing frequency, in 2002, 2016, 2017, 2020 and 2022."

Reef-devouring predator survives coral bleaching and feasts on the survivors
"Research conducted by marine biologists from the University of Sydney has found juvenile crown-of-thorns starfish can withstand tremendous heat waves well above levels that kill coral. These starfish then develop into carnivorous predators that devour reefs just as they begin to regrow."

Coral researchers see ‘mass mortality’ amid Florida Reef bleaching crisis
Iconic elkhorn and staghorn corals took the heaviest losses, and researchers say they are at risk of becoming “functionally extinct” in the Florida Reef.
