Guardian: Prof Justin Marshall, a marine biologist and neuroscientist, has witnessed the coral around Lizard Island on the Great Barrier Reef change from a healthy brown to white over 30 years as a result of bleaching. He says he has never seen it in a worse state. Coral bleaching is caused by the ocean warming over a long period, which in this case is believed to have been caused by the El Nio effect, on top of climate change over many years

Coral bleaching at Barrier Reef 'severe': Australia
2016-03-20 10:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Australian authorities said Sunday coral bleaching occurring in the World Heritage-listed Great Barrier Reef had become "severe", the highest alert level, as sea temperatures warm. Australian Environment Minister Greg Hunt said while the bleaching at this stage was not as severe as in 1998 and 2002, also El Nino-related events, "it is however, in the northern parts a cause for concern".

NASA's CORAL Mission Takes Reef Studies To New Level
2016-01-12 20:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: NASA plans to take a new and improved approach to studying coral reefs this year, with the launch of a three-year field expedition conducted with advanced instruments to survey the world's reefs in far greater detail than ever before. Researchers from the COral Reef Airborne Laboratory (CORAL) will take aerial and up-close, underwater measurements to better assess the condition of these threatened ecosystems. Their findings will be used to create a unique database of uniform scale and quality,...
