Things aren't looking good by 2100, according to new simulations

(Newser) - "Honestly, most sites are out." That's the grim pronouncement from a University of Hawaii at Manoa researcher who looked at the likely status of the planet's coral reefs by 2100 based on projected climate conditions. Renee Setter and her team discovered that small areas of Baja...

Mysterious Killer Is Striking Florida's Coral Reefs

Scientists are racing to identify the pathogen and find a cure

(Newser) - Something is turning healthy coral into ghostly skeletons along the Florida Reef Tract. As the third-largest barrier reef in the world, the 360-mile stretch of vitally important sea life provides a buffet of nutrients for plants and animals along the state's Atlantic coast.

'Mass Mortality' Hits Great Barrier Reef, Shocks Scientists

'Unprecedented bleaching event' killed off half the coral there over 2 years

(Newser) - An "unprecedented" bleaching event struck the Great Barrier Reef in 2016, with perilously high temperatures affecting the 1,400-mile-long stretch of coral. The Atlantic notes we already knew that this occurred , but that the toll is just now being fully understood: It describes a new study published in the...

This Could Be the Only Way to Save the Great Barrier Reef

Cloud brightening could cool the ocean just enough: researchers

(Newser) - You'd think the search for a solution to bleaching coral in the Great Barrier Reef would have scientists looking down into the ocean, rather than up at the sky. But clouds could be key to combating warming ocean temperatures blamed for the bleaching, say Australian researchers. They believe that...

Scientists Warn That Coral Reefs Face Total Wipeout

We've already lost half in just 30 years

Bleaching Kills a Third of Barrier Reef Coral

It's even worse in some parts of world's biggest reef
