Coral Triangle could be last bastion for planet's beleaguered reefs
2014-11-27 15:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: If humans are driving earths sixth great extinction event, coral reefs will be one of the first and most visible ecosystems to succumb. Scientists estimate that by 2050, the ocean could be largely devoid of reefs as climate change and our relentless plundering of the sea set in motion geological changes not seen for millions of years. But according to the Catlin Seaview Survey, a multi-year project to map the worlds coral reefs, there may be evidence that certain reefs in the Coral Triangle...

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...
How is a warming climate impacting coral reefs?
2014-09-10 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: How is a warming climate impacting life in the oceans? Fish can move to cooler areas, but coral reefs are anchored in place. Late-summer water temperatures near the Florida Keys were warmer by nearly 2 degrees Fahrenheit in the last several decades compared to a century earlier, according to a new study by the U.S. Geological Survey. Researchers indicate that the warmer water temperatures are stressing corals and increasing the number of bleaching events, where corals become white resulting from...

Protection of Parrotfish Could Slow Decline of Caribbean Reefs
2014-07-08 19:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: The steady loss of coral reefs in the Caribbean could be partially reversed by taking a number of relatively simple steps, including stronger measures to protect the regions parrotfish, according to a new study. In a review of trends in Caribbean coral reefs from 1970 to 2012, the Global Coral Reef Monitoring Network said that live coral only makes up about 17 percent of the regions reef surfaces today. If present trends continue, the study said, coral reefs in the Caribbean will virtually disappear...

Caribbean coral reefs could disappear "within a few decades."

Vox: Coral reefs in the Caribbean are on track to "virtually disappear within a few decades," a major new report warns. But there's also a way to slow decline. Protecting just a single fish -- the brightly colored parrotfish -- could help save the reefs from doom. There's little doubt that the Caribbean's coral reefs have declined sharply since the 1970s, under heavy stress from invasive pathogens, overfishing, coastal pollution, tourism, and now global warming that's heating up the oceans. It's...
