Bleached corals bounce back to normal growth rates faster when they have clean water and lots of sea life at their side, a U.S. university study indicated. The study, lead by scientists at Scripps Institution of Oceanography at University of California-San Diego, suggests that better overall ocean health means corals are better able to recover from bleaching events, the university said in a news release. Bleaching events occur when rising sea temperatures force corals to spew out symbiotic...

A new study shows that bleached corals bounce back to normal growth rates more quickly when they have clean water and plentiful sea life at their side The new research study led by scientists at Scripps Institution of Oceanography at UC San Diego suggests that by improving overall ocean health, corals are better able to recover from bleaching events, which occur when rising sea temperatures force corals to expel their symbiotic algae, known as zooxanthellae. Coral bleaching is a phenomenon...

Better coral reef assessment and management are needed if the reefs are to survive global warming, a conservation group said Wednesday in Washington. The International Union for Conservation of Nature and Natural Resources made the statement in releasing a report Resilience Assessment of Coral Reefs. We already know that climate change is destroying coral reefs through warming waters that cause coral bleaching and through acidifying oceans that hinders coral skeleton growth, Garriel...

Experts say that more than half of the world's coral reefs could disappear in the next 50 years, in large part because of higher ocean temperatures caused by climate change. But now Stanford University scientists have found evidence that some coral reefs are adapting and may actually survive global warming. "Corals are certainly threatened by environmental change, but this research has really sparked the notion that corals may be tougher than we thought," said Stephen Palumbi, a professor of...

An Australian-led World Wild Life study predicts worldwide catastrophic losses of coral by the end of this century due to climate change. The WWF-commissioned study, led by University of Queensland Professor Ove Hoegh-Guldberg, determined coral reefs could disappear entirely from the Coral Triangle region of the Pacific Ocean, thereby threatening the food supply and livelihoods for about 100 million people. Researchers said averting such a catastrophe will depend on quick and effective global...

Scientists reported Thursday that a section of Australia's Great Barrier Reef - in danger of being killed by global warming within mere decades - has regenerated itself in record time. This partial regeneration is perhaps more appropriately being referred to as a mere "lucky escape" by the head of research for the authority that preserves the World Heritage-listed reef, Laurence McCook. Due to global warming, this expanse of badly damaged coral at Keppel Island began experiencing an increase...

Scientists assess a quarter-century of climate change effects on coral health and find both good and bad newsIn the journal Estuarine, Coastal and Shelf Science, University of Miami Rosenstiel School of Marine and Atmospheric Science Professor Dr. Peter Glynn, and 2008 Pew Fellow for Marine Conservation and Assistant Professor Dr. Andrew Baker, assess more than 25 years of data on reef ecosystems recovery from climate change-related episodes of coral bleaching. Coral bleaching "“ in...

The remainder of the world's coral is in danger of being eliminated as a result of human activities, pollution and over-fishing, according to an international report. Released on Wednesday, the "Status of Coral Reefs of the World: 2008" found that one fifth of the Earth's coral reefs have disappeared since 1950, and the remainder could die off over the next 20 to 40 years unless initiatives to curb greenhouse gas emissions are enforced. "Climate change must be limited to the absolute minimum...

New research in Australia has found disturbing new evidence to show that the world's coral reefs may be in more immediate danger than some experts previously considered. Australian scientists studied the effects of climate change and rising sea temperatures to find that these events may speed the process of coral bleaching, thus leading to the destruction of the world's reefs. "Previous predictions of coral bleaching have been far too conservative, because they didn't factor in the effect of...

Scientists are using satellites to expand a network to watch for ocean temperature increases that can harm fragile ecosystems worldwide. On Thursday, the National Oceanic and Atmospheric Administration said its Coral Reef Watch network had been expanded from 24 locations to 190 locations in the Florida Keys, the Caribbean, Australia, Hawaii, Indonesia, and in other areas across the globe. The organization monitors ocean temperatures in nearly a dozen coral reefs.  The larger, expanded...
