'Let's Kick Climate Change Denial Out of Football' campaign

Football fans who make offensive chants about wind turbines could face stiff jail sentences under plans by the government and the Football Association to ‘get tough’ with climate change deniers.

What's all this then?

The blogospheric dissection of the papers by Spencer and Braswell and by Dessler continue apace. In fact the pace is a bit of a problem, as I have been left rather behind - radiative physics is an area I need to get up to speed on. This is a pity because it looks as though today's excitement is all going to be focused the effect of clouds on the earth's energy budget.

Firstly there is this comment by Bart at CA. Then there's this post by Tallbloke, which is essentially just a reposting of a comment by Bill Illis at WUWT.

The Bill Illis/Tallbloke piece seems rather more straightforward to me - if I understand it correctly, it shows that the variability in the amount of heat escaping the earth is driven to a large extent by changes in cloud cover. As one commenter puts it:

But the [climate models] only assign a single, constant value for all clouds, at all latitudes, for all periods of day and night, for all seasons of the year, across all elevations for all values of humidity and rainfall and percent CO2.

Right?

I can see that this is a problem, although perhaps I haven't quite got my head around the implications yet.

The Bart comment at CA is, however, more tricky and I haven't made head or tail of it yet. Given that there seems to be general agreement that it may be significant, maybe readers here can explain.

Maths do better - Josh 118

H/t Chuckles who, on the Make haste more slowly post, wrote:

"Does this mean that John Abrahams comments, reported in the Guardian and Daily Climate, about Dr. Spencer constantly having to correct errors and revise work, are in fact correct?

Just not in the way Abrahams originally intended?"

New paper supports Svensmark hypothesis

Nigel Calder reports on a paper by Dragić et al.. The paper considers the effects of Forbush decreases - when solar flares cause reductions in the number of galactic cosmic rays reaching the Earth. According to the Svensmark hypothesis, this should cause a reduction in cloudiness.

Dragić and his co-authors have looked at the diurnal temperature range - the difference between daytime maxima and nighttime minima after Forbush increases. If clouds are indeed reduced, then the diurnal temperature range should increase, ie colder nights and warmer days.

The results look good for Svensmark's ideas.

The results [are] hard (impossible?) to explain by any mechanism except an influence of cosmic rays on cloud formation.

Bradley on the Hockey Stick 2

Time after time when reading Bradley's defence of the Hockey Stick, I was struck by how he avoided the criticisms that were actually made of the paper, preferring instead to knock down a series of strawmen. There are also parts that are grossly misleading.

Take this next excerpt for example, where Bradley describes McIntyre and McKitrick's Nature submission in 2004.

Cuccinelli on hold

From HamptonRoads.com:

An Albemarle County judge has put Attorney General Ken Cuccinelli's latest demand for documents related to a former University of Virginia climate-change researcher's work on hold.

Circuit Judge Cheryl Higgins granted a stay today until the Virginia Supreme Court rules on a related case.

Cuccinelli is investigating whether Michael Mann defrauded taxpayers by using manipulated data to obtain government grants. A judge ruled last year that Cuccinelli was not specific enough about how Mann might have broken the law, and that he lacks authority to investigate federal grants.

Cuccinelli, a global warming skeptic, appealed that ruling to the Virginia Supreme Court and filed a new, more specific demand pertaining to just one state grant. Higgins put that demand on hold.

Make haste more slowly

What fun - readers point out that some revisions are to be made to the Dessler paper in the light of comments made by Roy Spencer. I wonder if Steve M's comments will have an effect too?

Paul Nurse on geoengineering

Paul Nurse has a letter in the Guardian (where else?) on the subject of geoengineering. It's less bad than you might expect.

A time may come when mankind will need to consider geoengineering the climate to counteract climatic effects of greenhouse gases. If that time comes, we need to have a good understanding of whether such efforts will work and, just as importantly, whether they will have any negative side effects. Those who oppose such exploratory research on the grounds that we do not know what its effects may be ... are missing a fundamental point of research, which is to allow us to potentially rule out any technology that would have negative effects that outweigh the positive.

Researching stuff probably does little harm, although one can certainly question whether geoengineering research, or indeed any scientific research, should be a priority for government spending at the moment. Outside the ivory tower, times are hard, but it is not obvious that Sir Paul has noticed.

Coopting extremes

Nature reports on a new project to investigate links between extreme weather and global warming.

"The idea is to look every month or so into the changing odds" associated with that influence, says Peter Stott, a climate scientist with the UK Met Office's Hadley Centre in Exeter and a leader of the ACE group. Stott is writing a white paper laying out plans and requirements for a near-real-time attribution system, which he will present in October at the World Climate Research Programme conference in Denver, Colorado.

Dear Kev seems to be involved.

Commenting

Once again, there is a new fix (?) for the commenting issues on the blog.

Can you let me know how it goes please.

Good luck!

Does pre-emptive deletion get round the EIR?

This is a guest post by David Holland.

Two recent Decision Notices appear to uphold the idea, popular with some climate scientists, that pre-emptive deletion of information gets round the Environmental Information Regulations. The first relates to University of East Anglia and the email to which Phil Jones attached the CRUTEM data he sent to Georgia Tech. The second relates to the University of Edinburgh and the Russell Review correspondence, all of which was deleted by the University very soon after the Review Report was released. This was well before we learnt all about Geoffrey Boulton's editing of my evidence submission, and Graham Stringer saying the Review was beyond parody.

Fiona Fox responds to Research Fortnight

When the BBC published its review of science, Research Fortnight published a leader criticising Steve Jones' report, saying it was "a victory for the forces of public relations". Now Fiona Fox, of Science Media Centre fame, has responded.

The leader also assumes that research press officers do little but promote beautifully crafted, peer-reviewed studies on new breakthroughs. But what about the press officers at the University of Oxford who spent years persuading reluctant university authorities to open up their animal research facilities to the media, despite a history of violent attacks from animal rights extremists? What about the Imperial College London press officer who spent her weekends and evenings supporting David Nutt after he was sacked as drugs adviser by the Home Secretary? What about the University of East Anglia press officers who managed the fallout from ‘climate-gate’ for over a year while the world sat in judgment on their media-relations strategy?

Can she really not know that the PR campaign at UEA was run by the Outside Organisation?

Bradley on the Hockey Stick

I'm currently reading Raymond Bradley's new book Global Warming and Political Intimidation, which is very interesting. The sense I get from the book is of a minor civil servant trying to justify some almighty great shambles over which he has presided, which in a way is what the Hockey Stick story is about.

It's a very political work, with Bradley apparently seeing pretty much everything through a political lens: in several places in the book we are presented with stories of valiant Democrats defending honest scientists from wicked Republicans. We have, in essence, a minor civil servant who thinks he's living in a fairy tale and trying to justify himself to the world.

Because of this political focus, there is remarkably little discussion of the science and although there is a chapter on the Hockey Stick, there is no mention of bristlecones or principal components analysis. (And before you ask, no, he doesn't mention the Hockey Stick Illusion either). However, he does make an attempt to defend the science of the Hockey Stick, and my attention is going to be focused there. There's quite a lot to say on this subject, however, so I'm going to break the analysis down into separate posts.

WSJ on Svensmark

Anne Jolis has written an very nice, level-headed review of Svensmark and the CLOUD experiment.

But a few physicists weren't worrying about Al Gore in the 1990s. They were theorizing about another possible factor in climate change: charged subatomic particles from outer space, or "cosmic rays," whose atmospheric levels appear to rise and fall with the weakness or strength of solar winds that deflect them from the earth. These shifts might significantly impact the type and quantity of clouds covering the earth, providing a clue to one of the least-understood but most important questions about climate. Heavenly bodies might be driving long-term weather trends.

The theory has now moved from the corners of climate skepticism to the center of the physical-science universe: CERN, also known as the European Organization for Nuclear Research. At the Franco-Swiss home of the world's most powerful particle accelerator, scientists have been shooting simulated cosmic rays into a cloud chamber to isolate and measure their contribution to cloud formation. CERN's researchers reported last month that in the conditions they've observed so far, these rays appear to be enhancing the formation rates of pre-cloud seeds by up to a factor of 10. Current climate models do not consider any impact of cosmic rays on clouds.

Law Mann

The American Tradition Institute have just revealed that Michael Mann has engaged lawyers to try to intervene in the FOIA case between the institute and the University of Virginia.

Dr. Michael Mann, lead author of the discredited "hockey stick" graph that was once hailed by the UN Intergovernmental Panel on Climate Change as the "smoking gun" of the catastrophic man-made global warming theory, has asked to intervene in American Tradition Institute's Freedom of Information Act lawsuit that seeks certain records produced by Mann and others while he was at the University of Virginia, for the purpose of keeping them hidden from the taxpayer.

Specifically over the weekend ATI's Environmental Law Center received service from two Pennsylvania attorneys who seek the court's permission to argue for Dr. Mann to intervene in ATI's case. The attorneys also filed a motion to stay production of documents still withheld by UVA, which are to be provided to ATI's lawyers in roughly two weeks under a protective order that UVA voluntarily agreed to in May. Dr. Mann's lawyers also desire a hearing in mid-September, in an effort to further delay UVA's scheduled production of records under the order.

Dr. Mann's argument, distilled, is that the court must bend the rules to allow him to block implementation of a transparency law, so as to shield his sensibilities from offense once the taxpayer – on whose dime he subsists – sees the methods he employed to advance the global warming theory and related policies. ATI's Environmental Law Center is not sympathetic.
