The permafrost giant is stirring

We predict that the PCF [permafrost carbon flux] will change the Arctic from a carbon sink to a source after the mid-2020s and is strong enough to cancel 42–88% of the total global land sink. The thaw and decay of permafrost carbon is irreversible…

Brits view climate change as a current or imminent threat

Fully 83% of them do, as reported at Climate Progress.

The public’s belief in global warming as a man-made danger has weathered the storm of climate controversies and cold weather intact, according to a Guardian/ICM opinion poll published today.

Asked if climate change was a current or imminent threat, 83% of Britons agreed, with just 14% saying global warming poses no threat. Compared with August 2009, when the same question was asked, opinion remained steady despite a series of events in the intervening 18 months that might have made people less certain about the perils of climate change.

So the so-called ‘climategate’ kerfuffle had no noticeable impact on public opinion. Continue reading Climate clippings 16 →

Beware the collapse of the planet’s lungs

Amazon drought is consistent with what scientific models predict for a warmer globe.

Normally, rainforests function like great carbon sinks, absorbing a large proportion of the CO2 that human activity produces. But in 2005, thanks to deforestation, the Amazon became a net emitter of carbon dioxide. In that year, the rainforest is estimated to have emitted some 5 billion tonnes of CO2, almost as much as the entire output of the United States.

We have a Climate Commission

February 11, 2011 Brian 65 Comments

Greg Combet has announced the establishment of a Climate Commission to be headed by Tim Flannery.

Mr Combet said the Climate Commission would provide expert advice and information on climate change to the Australian community.

“The Climate Commission has been established by the Gillard Government to provide an authoritative, independent source of information for all Australians,” he said. “It will provide expert advice on climate change science and impacts, and international action. It will help build the consensus required to move to a clean energy future.”

The Climate Commission would have a public outreach role, he said, to help build greater understanding and consensus about reducing Australia’s carbon pollution.

“The Commissioners are eminent Australians who are leaders in their fields and I’m pleased one of Australia’s leading science communicators, Professor Tim Flannery, a former Australian of the Year, has accepted the role of Chief Commissioner,” Mr Combet said.

“The Climate Commission will fulfil a key information and education role, enabling the Australian community to have a more informed conversation about climate change. I am delighted to lead this new Commission,” said Professor Tim Flannery.

Monckton madness

John Cook at Skeptical Science has a post on two of Monckton’s oft-repeated pieces of climate change misinformation – that climate sensitivity, a measure of how much the earth warms from rising CO2, is so low that you can burn coal with impunity and that sea levels are not going to rise much in the future.

Cook has conveniently collected all his articles on Monckton Myths. Indeed this one lists 15 of them together with their antidotes. For example, Monckton claims that Arctic sea ice loss is matched by Antarctic sea ice gain, whereas in fact Arctic sea ice loss is three times greater than Antarctic sea ice gain.

Oops, said I wasn’t going to mention ice this time. Continue reading Climate clippings 14 →
