These posts include a brief mention of a number of news items relating to climate change. They don’t preclude treating any of these topics at more length in a separate post.
They can also serve as an open thread so that we can keep each other informed on important climate news.
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.
The cost of climate mitigation
One of the problems with current economic thinking is that the economic baseline is assumed to be a world without climate change. We are still fixated on how the economy would perform if the historical climate went on forever. Forget that – future economic performance has a truckload of climate damages written into it.
The most important economic goal for climate policy is not to be as cheap as possible, or to necessarily get the biggest cuts (through that is important) – the key goal is to negotiate the transformation between seeing greenhouse gas abatement/sequestration as a cost to where it has a value. That is, the benefits of a low carbon economy are seen as so necessary, that there is a price embedded in the economy to see that happen. Competition within a market to deliver those benefits, driving innovation and development is the goal. China is adopting this type of paradigm as one of the incentives for the future development of their economy.
Food for thought. Effectively we need to internalise that climate mitigation needs to happen, there is no choice. And if it does we will be better off economically than BAU. Stern said it back in 2006.
Worse is yet to come
Especially food for thought because worse is yet to come in terms of bad weather, scientists say.
We’ll be looking at hotter maximum temperatures [by 2100], hotter minimum temperatures and droughts lasting longer, and heatwaves lasting longer than we have seen in the historical past. If you’re interested in rainfall, the thing that we are sure about is that rainfall will intensify, particularly convective rainfall.
So the sorts of rainfall that you see in monsoonal regions of northern Australia. The amount it will increase is much less clear. (Andy Pitman)
A 25% increase in rainfall, says Stella Whittaker.
Now what that means is that the large storms which we currently describe as 1 in 100 year storms, they are going to be more likely and it really means that people could see this type of event happening more than once in their lifetime.
You ain’t seen nothing yet.
The truth about why so wet?
Counterpoint, you’ll understand, is always on the lookout for the truth in relation to climate science. Now they’ve found it as expressed by hydro-climatologist Stewart Franks, who reckons that the big wet is due to natural variability. Franks reckons it’s the ENSO. He thinks we could be at the start of several decades of La Niña-dominated wet weather.
Quite possibly, but he did then he go on to say that the influence of increased CO2 is negligible and paid out on climate scientists who might tell you otherwise. But I can’t find that in the transcript. Strange!
He should get himself up to date, because…
Extreme weather is linked to climate change: study
Two Canadian scientists have found a link between intensifying extreme rain events and man-made greenhouse gas emissions.
The authors of the paper published in Nature today say extreme rains and floods increased by 7 per cent in the second half of last century right across the Northern Hemisphere.
Professor Roger Stone at the University of Southern Queensland thinks the results can be extrapolated to the Southern Hemisphere and specifically Australia.
The CSIRO models have already demonstrated that to I think a good extent, certainly for a region just such as south-east Queensland that we do get increased, enhanced what’s called deep convection under a climate change scenario.
Climate Progress is on the case:
Changes in extreme precipitation projected by models, and thus the impacts of future changes in extreme precipitation, may be underestimated because models seem to underestimate the observed increase in heavy precipitation with warming.
When you allow climate change deniers inside the tent
… they set about slashing climate change programs and indulge in polluter protection. Some clowns even want to defund climate change work at NASA. Apparently it “undercuts one of NASA’s primary and most important objectives of human spaceflight.”
But they didn’t have to worry about climate change legislation as such because it wasn’t there.
You’d have to agree that Obama serving up a cap and trade scheme to these monkeys would be a waste of time, or worse.
Meanwhile on the other side of the pond
Britons worry that the well-respected Committee on Climate Change will disappear in a ‘bonfire of quangos, or at least will be more timid in the interests of self-preservation.
Still in Britain businesses are being told to adapt to climate change or face the consequences.
Lord Smith of Finsbury, a cabinet minister in the last Labour government and chairman of the Environment Agency, said that while many companies were starting to take steps to reduce their emissions, few businesses had started to appreciate how rises in temperatures would impact on their operations.
“To the business world, I would say it is important to pay attention to cutting down on emissions, doing the mitigation stuff will be increasingly important. But it is equally important to see how you as a business will cope with those changes,” said Smith.

You might recall that she was the one who presided over the first part of the Copenhagen conference.
