Ruh Rohhhh, the AGW cultists didn't know about this I bet. It seems that the last 110 years of warmer waters off of the coast of Australia has been good for coral reef growth.
Yet ANOTHER assertion cast into doubt. Will they ever get something right? I doubt it...
The second link is to the Science abstract.......ruh rohhhhhh!
"A GOVERNMENT-RUN research body has found in an extensive study of corals spanning more than 1000km of Australia's coastline that the past 110 years of ocean warming has been good for their growth.
The findings undermine blanket predictions that global warming will devastate coral reefs, and add to a growing body of evidence showing corals are more resilient than previously thought, up to a certain point.
The study by the commonwealth-funded Australian Institute of Marine Science, peer-reviewed findings of which are published in the leading journal Science today, examined 27 samples from six locations from the West Australian coast off Geraldton to offshore from Darwin.
At each site, scientists took cores from massive porites corals - similar to a biopsy in humans - and counted back to record their age in much the same way tree rings are counted. Although some cores extended back to the 18th century, they focused on the period from 1900 to 2010.
The researchers found that, contrary to their expectations, warmer waters had not negatively affected coral growth. Quite the opposite, in fact: for their southern samples, where ocean temperatures are the coolest but have warmed the most, coral growth increased most significantly over the past 110 years. For their northern samples, where waters are the warmest and have changed the least, coral growth still increased, but not by as much.
"Those reefs have actually been able to take advantage of the warmer conditions," said Janice Lough, a senior AIMS research scientist and one of the study's authors.
Maria Byrne, a professor of marine biology at Sydney University, said after reading the paper that its findings "made perfect sense". "Temperature rules metabolism, so it's a no-brainer that if you get more temperature you will get more metabolism."
