Massive expansion of ocean survey to study impact of climate change on coral reefs

2013-08-01 09:34:00| Climate Ark Climate Change & Global Warming Newsfeed

Treehugger: Last year's seminal coral reef survey of the Great Barrier Reef by the Catlin Seaview Survey was just the tip of the proverbial iceberg when it comes to documenting and understanding the effects of climate change and ocean acidification on the world's coral reefs, but it was a big step in learning about the changes that are happening under the ocean. And now the Catlin survey is launching a massive new campaign that will put its focus on the Caribbean and Bermuda, taking hundreds of thousands...

Oysters, reefs, and swamps protect billions' worth of real estate for free

Climate Desk: Among the hundreds of recommendations listed in Mayor Michael Bloomberg`s $20 billion plan to protect New York from climate change is a call to stock up on oysters. Not the kind you`d want to knock back with a nice pilsner on a Friday afternoon: The idea is to build large underwater oyster reefs around the harbor that could prevent coastal erosion and absorb storm surges. "Soft" infrastructure like this--reefs, wetlands, dunes, and other "natural" systems--is gaining in popularity over "hard" levees...

Sand dunes, coral reefs protect coasts against climate change

Hill: Protecting sand dunes and coral reefs can help defend the United Statess coasts against costly extreme-weather events linked to climate change, according to a new study. Maintaining coastal habitats could halve the people, low-income families, the elderly and total value of residential property most exposed to rising sea levels, floods and storms associated with climate change, the study concluded. Extreme weather, sea-level rise and degraded coastal ecosystems are placing people and property...

Dunes, reefs protect US coasts from climate change

2013-07-14 23:24:00| Climate Ark Climate Change & Global Warming Newsfeed

USA Today: Rising sea levels and extreme weather put 16% of U.S. coastlines at "high-hazard" risk and the number of threatened residents could double if natural habitats -- sand dunes, coral reefs, sea grasses, mangroves -- aren't protected, Stanford University researchers say in a study today. The study, noting that 23 of the 25 most densely populated U.S. counties are coastal, comes as U.S. and local officials are looking at "hardening" shorelines with billion-dollar sea walls and other projects in the...

Coral Reefs Face Point of No Return

Climate News Network: Without deep cuts in carbon dioxide emissions, the planets coral reefs could be in serious trouble. In a world in which humans continue to burn fossil fuels unchecked, ocean conditions will become ultimately inhospitable, according to U.S. scientists. Katharine Ricke and Ken Caldeira of the Carnegie Institution in Washington and colleagues make their sombre prediction in Environmental Research Letters. Their argument on the face of it seems inconsistent with other recent research on reef response...
