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". "The reef is 2,300 kilometres (1,429 miles) long and the bottom three-quarters is in strong condition, but...

Ocean acidification already taking toll on coral reef growth
2016-02-26 08:53:00| Climate Ark Climate Change & Global Warming Newsfeed
Comment: Of particular concern are losses of older corals, which release more eggs and sperm during reproduction than young ones, and bleaching in nurseries of corals established to replace those that die off. The findings were published in the science journal Nature. Can we administer a similar procedure to save the reefs globally? Qld Senator Larissa Waters is the Australian Greens Deputy Leader and climate change spokesperson. But even if the experiments underlying the study did exactly that,...
