Scientists expect Hawaii's worst coral bleaching ever

Associated Press: Warmer-than-normal ocean temperatures around Hawaii this year will likely lead to the worst coral bleaching the islands have ever seen, scientists said Friday. Many corals are only just recovering from last year's bleaching, which occurs when warm waters prompt coral to expel the algae they rely on for food, said Ruth Gates, the director of the Hawaii Institute of Marine Biology. The phenomenon is called bleaching because coral lose their color when they push out algae. The island chain experienced...

15,000 sq km of coral reef could be lost in current mass bleaching, say scientists

Guardian: A massive coral bleaching event currently ravaging coral reefs across the globe could destroy thousands of square kilometres of coral cover forever, US government scientists have said. In figures exclusively released to the Guardian, scientists from the US National Oceanic and Atmospheric Administration (Noaa) said about 12% of the worlds reefs have suffered bleaching in the last year. Just under half of these, an area of 12,000 sq km of coral, may be lost forever. But the devastation is only...
How some corals recover from 'bleaching': climate study

Agence France-Pressew: A sharp rise in sea temperature can inflict potentially catastrophic "bleaching" on corals, but research published Wednesday identified factors that may render some reefs more resilient than others. Five conditions can determine whether or not a reef is doomed after bleaching -- episodes that threaten a valuable source of biodiversity, tourism and fishing, scientists reported in the journal Nature. "Water depth, the physical structure of the reef before disturbance, nutrient levels, the amount...

Global warming blamed for Pacific coral bleaching
2014-12-22 01:52:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: The Marshall Islands is experiencing its worst-ever coral bleaching as global warming threatens reefs across the entire northern Pacific, scientists said Monday. Marine researchers said an El Nino weather pattern had been developing in recent months, raising ocean temperatures and stressing delicate coral reefs. "The worst coral bleaching event ever recorded for the Marshall Islands has been occurring since mid-September," Karl Fellenius, a Majuro-based marine scientist with the University...
