Ocean warming and acidification deliver double blow to coral reefs

2013-09-30 10:59:00| Climate Ark Climate Change & Global Warming Newsfeed

Arstechnica: The dual threats of ocean acidification and anthropogenic warming have the potential to wreak havoc on marine life over the coming decades. Corals require acid-sensitive calcium carbonate for structure and heat-sensitive symbionts for sustenance, so they seem to have the most to lose from a warmer, more acidic ocean. Indeed, numerous studies have already indicated that calcifying organisms, including corals, would be among the worst to suffer. Although many studies have looked at heat and acidification,...

Saving Reefs by Enlisting Citizens as New Scientists

2013-08-31 17:31:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate News Network: Ever wanted to see a coral reef up close? What until now has been a privilege reserved to a small minority is about to become something millions of us can (virtually) do. Scientists have hit on a way to harness 360-degree panoramas from Google's underwater street-view format in order to let anyone with access to a computer see reefs in real time. Scientists are using the eyes of citizen scientists to collect data and raise awareness about the health of coral reefs through underwater images...

Tourism threatening white sand beaches, coral reefs in Asia

2013-08-27 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Asahi Shimbun: The white sand beaches make Boracay island one of the world's favorite tourist destinations. However, over-development and a lack of social infrastructure are threatening to swallow up this valuable tourist asset. The problem is clearly evident every day as tourists, who were at one point relaxing on deck chairs set out on the beach, have to hike up their shorts and dresses as tides come rolling in right up to where their hotels are located. Dionisio Salme, the owner of a hotel on Boracay,...

Why Some Coral Reefs Might Survive Climate Change

2013-08-14 16:01:00| Climate Ark Climate Change & Global Warming Newsfeed

Popular Science: The world is clobbering coral reefs, home to 25 percent of all marine species. Agricultural runoff pollutes the water around them; coastal developments tear them up; overfishing kills their inhabitants; and carbon dioxide emissions make the oceans too hot and acidic. In a provocative op-ed for the New York Times last year, Roger Bradbury, an ecologist at Australian National University, declared that reefs are zombie ecosystems . . . on a trajectory to collapse within a human generation. The slightly...

New study finds 80% of Caribbean coral reefs destroyed since 1960s

Guardian: A major survey of the coral reefs of the Caribbean is expected to reveal the extent to which one of the worlds biggest and most important reserves of coral has been degraded by climate change, pollution, overfishing and degradation. The Catlin scientific survey will undertake the most comprehensive survey yet of the state of the regions reefs, starting in Belize and moving on to Mexico, Anguilla, Barbuda, St Lucia, Turks & Caicos, Florida and Bermuda. The Catlin scientists said the state...
