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,...

Effect ocean acidification: Coral growth rate Great Barrier Reef plummets 30-year comparison
2014-09-18 02:06:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A team of researchers working on a Carnegie expedition in Australia's Great Barrier Reef has documented that coral growth rates have plummeted 40% since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown. In a quest for historical context on the peril facing coral reefs, the team compared current measurements of the growth rate of a section of Australia's Great Barrier Reef with similar measurements taken more than 30 years...

Ocean Acidification Threatens Economies and Cultures Around World
2014-08-21 18:12:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Ocean Conservancy intern Alexis Valauri-Orton spent the last year on a journey around the world learning about ocean acidification. She visited marine communities most at risk from ocean acidification and saw firsthand how dire the need is for more research, guidance and infrastructure to prepare for the challenges ahead. She produced a video, shown below, to help make the stories from her recent blog posts come alive. Valauri-Orton encourages you to watch her video and Listen to Waiaria talk...

Oceans rising acidification eating away at shellfish that coastal tribes depend on
2014-08-15 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Indian Country: The ancestral connections of tribal coastal communities to the oceans natural resources stretch back thousands of years. But growing acidification is changing oceanic conditions, putting the cultural and economic reliance of coastal tribes--a critical definition of who they are--at risk. Its a big challenge to tribes in the Pacific Northwest, said Billy Frank Jr. (Suquamish) back in 2010, addressing the 20 tribes that make up the Northwest Indian Fisheries Commission. Its scary, he said...
Ocean acidification poses imminent threat to Alaskan fishing communities
2014-08-09 12:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Salon: Keeping Alaskas fisheries wild and sustainable is going to be a serious challenge in the years ahead as our oceans become more acidic, and that in turn, is going put many Alaskans subsistence way of life at risk, says a new report. Many of the nutritionally and economically valuable marine fisheries in the state are located in waters that are already experiencing ocean acidification, says the report, Ocean Acidification Risk Assessment for Alaskas Fishery Sector that was published online...
