Nature World: Ocean acidification and coral reef damage is likely going to cost the world economy over a trillion dollars by 2100, according to a new report by United Nations (UN) experts. The report was released on Wednesday by the UN Convention on Biological Diversity, which has been assessing the economic impacts climate change and degrading biodiversity could have on the world. The report, called "An Updated Synthesis of the Impacts of Ocean Acidification on Marine Biodiversity," details how the ocean's...

Acid damage to coral reefs could cost $1 trillion
2014-10-08 19:46:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: Ocean acidification is set to cost us $1 trillion by 2100 as it eats away at our tropical coral reefs. That's the warning from a report released today by the United Nations Convention on Biological Diversity, which assesses the economic impacts the problem could have. The ocean's pH is now 8.0, down from 8.1 in the mid-18th century. Because the pH scale is logarithmic, this change means that, over the past 250 years, the world's oceans have seen a 26 per cent increase in acidity - a result...
High rate of coral bleaching seen around Hawaiian island of Oahu
2014-10-08 02:45:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: A survey of coral reefs off the Hawaiian island of Oahu has shown warm ocean waters recently contributed to a higher rate of coral bleaching than the state has seen in decades, sparking concerns about the ecosystem, a state official said on Tuesday. The findings from dives last week by researchers with the Hawaii Division of Aquatic Resources follows federal warnings of a possible large decline in coral cover in the archipelago this century due to climate change and warming oceans. Coral underpins...
Coral Bleaching Event: Worst in Decades
2014-10-07 18:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Scientists are frantically monitoring Hawaii's unusual windless coast, finding that elevated sea surface temperatures are severely stressing corals near the shoreline, causing a major coral bleaching event that's even more intense than one seen two decades ago. "Unfortunately, we are seeing evidence of wide-spread bleaching in shallow, near shore waters of windward Oahu," Frazer McGilvray, the administrator of the Division of Aquatic Resources (DAR) Coral Rapid Response Team, said in a recent...

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...
