Hotat barriärrev?

Slänger in det nedan med tanke på alarmism i DN och SvD om australiska Stora Barriärrevet. SvD beskriver en viss arts (Porites) marginellt lägre tillväxt med rubriken "Korallreven växer knappt längre", och trots att orsak till detta är okänd (variation brukar ha naturliga förklaringar) har DN rubriken "Varma och sura hav slår mot korallrev".


The Australian publicerar artikeln Friends of the Reef not worried about global warming, om forskare i området som istället menar att barriärrevet mår ypperligt.

The Australian-artikeln kommenteras så här i en blogg:

The Australian Greens and Eco-Fundamentalist have declared that Australia’s ETS reduction target of 5% means we will lose the Great Barrier Reef.

Ask any green and they will swear that’s the truth even though they have never visited one square inch of The Great Barrier Reef which includes over 2900 reefs, around 940 islands and cays, and stretches 2300 kms along the Queensland coastline.

Heres what a couple of guys who dive the reef most days have to say:

Shark expert Ben Cropp said yesterday the outer reef was more or less the same as when he started diving 50 years ago….. I’ve got a gut feeling the reef will cope with climate change, if it exists, but that’s just a gut feeling. Scientists say you aren’t allowed to have a gut feeling, but my gut feeling is based on diving the reef for half a century. But then again, I’m not their kind of expert.

And Patrick Ligthart, is a volunteer with the Low Isles Preservation Society and cleans away rubbish and maintains the reefs around the Low Isles.

… said his section of the reef had never looked better, and he was sceptical about predictions of its demise… I come out to the reef all the time, and the reef’s in good shape…. even old timers say the reef here has never looked better.

I don’t know why these fear-mongers keep making these claims

Yet Bob Brown and The Greens continue unabated with their fear mongering claims that Climate Change is killing the iconic Great Barrier Reef.

It follows then that Brown and the Greens would lie to the Australian public about other things too.

Även i Herald Sun påpekas att forskare inte ser några problem (min fetstil):

PROFESSOR Ove Hoegh-Guldberg, of Queensland University, is Australia's most quoted reef expert.

He's advised business, green and government groups, and won our rich Eureka Prize for scares about our reef. He's chaired a $20 million global warming study of the World Bank.

In 1999, Hoegh-Guldberg warned that the Great Barrier Reef was under pressure from global warming, and much of it had turned white.

In fact, he later admitted the reef had made a "surprising" recovery.

In 2006, he warned high temperatures meant "between 30 and 40 per cent of coral on Queensland's great Barrier Reef could die within a month".

In fact, he later admitted this bleaching had "a minimal impact".

In 2007, he warned that temperature changes of the kind caused by global warming were again bleaching the reef.

In fact, the Global Coral Reef Monitoring Network last week said there had been no big damage to the reef caused by climate change in the four years since its last report, and veteran diver Ben Cropp said this week that in 50 years he'd seen none at all.

Lesson: Reefs adapt, like so much of nature. Learn again that scares make big headlines and bigger careers.

Vidare har forskare rapporterat att i tsunamin skadade indonesiska korallreven återhämtat sig långt snabbare än man trodde skulle ske: ABC News. (Sånt här refuseras väl på vissa nyhets- och vetenskapsredaktioner...)


En tidigare bloggpost av recon om korallrev förtjänar också att nämnas.

Uppdatering (5 jan): NOAA:s temperaturmätning vid Stora Barriärrevet har resultatet enligt nedanstående diagram. En marginell temperaturökningstrend kan förstås finnas, men knappast något exceptionellt. Hat tip och detaljer: Jennifer Marohasy.
