More attention-seeking over coral
In Australia, prophecies of doom for coral reefs go back long before the global warming scam, but coral reefs just fluctuate as they always have. I like this bit "if and when the climate is stabilised". That shows how little science is involved, seeing that the climate has been stable since 1999.
I know it is awkward of me to mention it again but may I remind all and sundry that even Hoagy (Prof. Ove Hoegh-Guldberg), Australia's no.1 coral doomster has noted now in a joint journal article the "astonishing regenerative capabilities of the dominant branching Acroporid corals".
Come to think of it, Hoagy has been very quiet since he co-published that article

CORAL reefs are so damaged their only chance for survival may be to freeze some species and reintroduce them to the sea in the future. The BBC is reporting the proposal, which was presented to 16 major economies at a Copenhagen meeting organised by the Global Legislators Organisation for a Balanced Environment (Globe).
Scientists speaking at the conference said the instability of climate change and rising ocean temperatures mean damage to reefs around the world is almost irreversible, the BBC said. The proposal suggested freezing samples that could then be reintroduced to their native oceans if and when the climate is stabilised.
It also comes as the Federal and West Australian governments draw up proposals to have Ningaloo Reef listed as a World Heritage site. The application is expected to be ready by February, leaving it up to international authorities to decide whether or not the reef qualifies for the status.
Emily Twiggs, an applied geology researcher at Perth's Curtin University, said Ningaloo was already well known as one of the world's best coral reef "laboratories". Supported by WA's Marine Science Institution (WAMSI), Ms Twiggs and her Curtin University supervisor, Associate Professor Lindsay Collins, have spent several years studying reef core samples of the eastern Ningaloo Reef within the Exmouth Gulf.
The samples, which have given them a history of the reef's growth over several thousand years, are being used to discover how the reef has responded to environmental change, including sea-level fluctuations, coastal flooding and cyclone activity. The reef's isolation, pristine waters and untouched corals made it the ideal place to monitor the response of coral reefs to climate change, Ms Twiggs said. "Reefs in general and the Ningaloo in particular, provide an excellent barometer with which we can monitor a changing environment," she said. "Corals can be quite resilient to environmental change. When sea levels rise or fall, corals can often alter their growth patterns to respond.
"But when change is really rapid, [Would a thermonuclear blast be rapid enough? Despite being a nuclear test site, Bikini atoll still has an abundance of coral] or there are multiple factors, then there is the potential for entire reefs to die out. "Because it is largely untouched by human activity, the Ningaloo Reef is one of the better coral reefs to study the impact of climate change. "This is especially true when compared with examples like the Great Barrier Reef in Queensland, which has been largely impacted by human activity."
Ms Twiggs said the greatest threats to coral reefs because of climate change were rapid increases in sea level, increased ocean acidity, a significant rise in sea surface temperature and more intense storm activity. "If current estimates on climate change are correct, all four of these factors are likely to occur together," she said. "This would likely place reefs such as the Ningaloo at risk."
