Corals can protect themselves from rising sea temperatures: Study
2013-10-24 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: TONY EASTLEY: There are signs that corals are more resilient than marine scientists first thought. Australian researchers have discovered corals can protect themselves from rising seawater temperatures. The study has found that they produce their own antioxidant to help keep them alive when they're under stress. Stephanie Smail reports. STEPHANIE SMAIL: It was researcher Cherie Motti's nose that led her to the discovery. CHERIE MOTTI: I was handed this sample. I opened the jar and...

Declining Corals May Drastically Affect Crustacean Biodiversity
2013-09-24 01:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: With many scientists expecting climate change to have a devastating effect on the worlds coral reefs over the coming century, new research from the University of Florida indicates that crustacean populations living near rapidly declining reef habitats could be at risk. Appearing in the November issue of the journal Geology, the new study is based on an analysis of the fossil record surrounding decapod crustaceans, a group that includes shrimp, crab and lobster. We estimate that earths decapod...

Why Are Some Corals Flourishing in a Time of Global Warming?
2013-09-10 18:38:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: As Earth's temperature climbs, the stony corals that form the backbone of ocean reefs are in decline. It's a well-documented story: Violent storms and coral bleaching have all contributed to dwindling populations, and increasing acidity of seawater threatens to take an additional toll. Less discussed, however, is the plight of gorgonian corals -- softer, flexible, tree-like species that can rise up like an underwater forest, providing a canopy beneath which small fish and aquatic life of all...
Brightening the clouds touted as a way to save corals
2013-07-10 19:17:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: CORALS are in dire straits, so it will take an ambitious plan to save them. Will cooling the climate locally by making clouds brighter help? Corals face a perfect storm of threats including acidifying oceans, invasive predators and tropical storms. Warmer waters also put them under stress, making them expel photosynthetic microbes that provide most of their energy as well as their vibrant colours, leaving them a bleached white. Without symbiotic microbes, the corals will die. To try to reduce...

New Scientist: The world's corals are in dire straits, so it will take an ambitious plan to save them. But will cooling the climate locally by making clouds brighter, the latest proposal on the table, help? Corals face a perfect storm of threats including acidifying oceans, invasive predators and tropical storms. Warming waters also puts them under stress, making them expel photosynthetic microbes that provide most of their energy as well as their vibrant colours, leaving them a bleached white. Without symbiotic...
