New Scientist: How are you keeping tabs on coral? The Catlin Seaview Survey (CSS) has captured 800,000 images of coral reefs from 22 countries in four years. It's the largest stocktake of the health of reefs worldwide in history. Right now we have an expedition in the Maldives. We really want to get good baseline data as we start to see the next coral bleaching event. Why should we focus on coral reefs? These reefs create a microcosm story: they are a metaphor for where the world is going, and one of the strongest...
Feds release recovery plan for elkhorn & staghorn corals
2015-03-06 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Florida Today: Federal officials today released a recovery plan for threatened elkhorn and staghorn corals. The plan by the National Oceanic and Atmospheric Administration identifies criteria that must be met before the two species can be removed from the list of threatened species under the Endangered Species Act. The plan includes two dozen actions to recover elkhorn and staghorn corals. It also addresses research and monitoring needs, as well as ways to ease threats and grow more coral at nurseries to...

Study projects unprecedented loss of corals in Great Barrier Reef due to warming
2015-01-23 05:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Science Daily: The coverage of living corals on Australia's Great Barrier Reef could decline to less than 10 percent if ocean warming continues, according to a new study that explores the short- and long-term consequences of environmental changes to the reef. Environmental change has caused the loss of more than half the world's reef building corals. Coral cover, a measure of the percentage of the seafloor covered by living coral, is now just 10-20 percent worldwide. The Great Barrier Reef, once thought to be...
How some corals recover from 'bleaching': climate study

Agence France-Pressew: A sharp rise in sea temperature can inflict potentially catastrophic "bleaching" on corals, but research published Wednesday identified factors that may render some reefs more resilient than others. Five conditions can determine whether or not a reef is doomed after bleaching -- episodes that threaten a valuable source of biodiversity, tourism and fishing, scientists reported in the journal Nature. "Water depth, the physical structure of the reef before disturbance, nutrient levels, the amount...

Gulf corals may hold key to future of reefs globally
2014-12-19 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Gulf News: When seawater temperatures reach 31 degrees Celsius, coral reefs the world over are unable to survive and begin to die off. Yet in the UAE coastal waters, where temperatures routinely top 35 degrees, coral reefs continue to thrive and survive, making them one of the hardiest marine life forms on the planet, experts say. As a result, many scientists are taking a renewed interest in studying the coral reefs of the region in order to gain a better understanding of how climate change could affect...
