Ocean Acidification Diminishing Great Barrier Reef Corals
2014-09-18 18:05:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Corals in the Great Barrier Reef are diminishing, and scientists are blaming ocean acidification for their dangerously low growth rates, a new study describes. Coral growth rates have plummeted 40 percent since the mid-1970s, and given that the Australian reef is the site of the largest collection of corals - over 400 types - scientists are getting worried. "Coral reefs are getting hammered," study leader Ken Caldeira of the Carnegie Institution said in a press release. Not only from ocean acidification,...

It's Survival Of The Fattest For Corals Adapting To Climate Change
2014-07-10 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: The future health of the world`s coral reefs and the animals that depend on them relies in part on the ability of one tiny symbiotic sea creature to get fat--and to be flexible about the type of algae it cooperates with. In the first study of its kind, scientists at The Ohio State University discovered that corals--tiny reef-forming animals that live symbiotically with algae--are better able to recover from yearly bouts of heat stress, called "bleaching," when they keep large energy reserves--mostly...

Hit by slime, Caribbean corals could vanish in two decades: report
2014-07-02 08:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Most coral reefs in the Caribbean could vanish in the next two decades, hit by the loss of fish and sea urchins that eat a slime of coral-smothering algae, a U.N.-backed study said on Wednesday. The review, the most comprehensive to date of Caribbean reefs that are vital tourist attractions for many island nations, said climate change had played only a minor role in the reefs' demise, despite past speculation it was a main cause. "With only about one-sixth of the original coral cover left, most...
Soft Corals Could Help Protect Reefs
2014-06-25 14:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Soft corals are more resilient to changes in oceanic acidity than previously believed, a new study has found. Coral reefs provide shelter to thousands of marine organisms. Rising levels of carbon dioxide and ocean temperature are threatening the existence of these beautiful "forests of oceans." A new study from Tel Aviv University researchers and colleagues has shown that soft corals can resist the harmful effects of decreasing pH in the ocean. The research is published in the journal PLOS One....

Corals dont lie: Centuries rising sea levels and temperature data revealed
2014-04-01 22:31:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: AIMS scientists together with a team from The University of Western Australia, CSIRO and the University of San Diego have analysed coral cores from the eastern Indian Ocean to understand how the unique coral reefs of Western Australia are affected by changing ocean currents and water temperatures. The research was published today in the international journal Nature Communications. The findings give new insights into how La Nia, a climate swing in the tropical Pacific, affects the Leeuwin current...
