Marine Heatwaves Severely Damage Australia Coral

Guardian: Marine heatwaves have wreaked "almost unprecedented' damage to ancient coral off Western Australia's Pilbara coast, scientists say. Scientists say the damage to ancient coral off Western Australia's Pilbara coast from marine heatwaves is "almost unprecedented.' Preliminary results from a 5-year year study of the coastline revealed that a remote section of reef south of Barrow Island has suffered severe "bleaching and decimation,' according to the CSIRO, which is running the study with the University...

Coral or coal decision looms for Australia's Great Barrier Reef
2014-01-30 08:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Australia's Great Barrier Reef watchdog is to decide by Friday whether to allow millions of cubic meters of dredged mud to be dumped near the fragile reef to create the world's biggest coal port and possibly unlock $28 billion in coal projects. A dumping permit would allow a major expansion of the port of Abbot Point for two Indian firms and Australian billionaire miner Gina Rinehart, who together have $16 billion worth of coal projects in the untapped, inland Galilee Basin. The Galilee Basin...

Pacific coral happy as acidity of the ocean rises

New Scientist: COULD corals survive ocean acidification against the odds? That's the hope raised by reefs found to be thriving in naturally acidified waters. Corals use the carbonate ions in water to build their skeletons from calcium carbonate. But ocean acidification caused by climate change reduces the available carbonate ions. Lab studies suggest that this leaves corals unable to grow and survive. The few known reefs living in naturally acidified water also tend to be unhealthy. So Kathryn Shamberger of the...

Loss of tropical coral reefs could be first irreversible climate consequence

InsideClimate: Many people are by now familiar with the Keeling curve, a graph showing the steady increase in carbon dioxide in the atmosphere measured over decades by the Mauna Loa Observatory, the world's longest-running CO2 monitoring station. The research, started by renowned climate scientist Dave Keeling in 1958, is considered one of the pillars of the scientific consensus that human activity is the main driver of climate change. This year, the data revealed a troubling milestone: CO2 concentrations had...

Species Diversity In Coral Reefs Hints At How Coral Responds To Climate Change
2013-12-14 13:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: It is widely known that coral reefs are being put in jeopardy by rising water temperatures caused by climate change. A team of marine biologists, led by Penn State University, has made a surprising discovery that suggests that very similar looking coral species actually differ in how they survive in harsh environments. "We`ve found that previously unrecognized species diversity was hiding some corals` ability to respond to climate change," said Iliana Baums, associate professor of biology at Penn...
