EPA stripped of power to regulate GhGs

The Energy and Commerce Subcomittee of the US House of Representatives has voted to strip the Environmental Protection Agency of the power to regulate greenhouse gases.

The sharply partisan vote was preordained by the Republican takeover of the House. Republicans and their industry allies accuse the administration of levying taxes on traditional energy sources through costly environmental regulations, threatening the economic recovery and driving jobs overseas.

Crushing of dissent

A high school student in Australia is struggling to keep quiet during climate change lessons...

For the third lesson the PowerPoint was brought out again with even more questionable statements claiming that putting more carbon dioxide into the atmosphere is causing: an increase in temperature by one degree; a rise in sea levels; more bush fires; more droughts; more animals to become extinct; malaria to become more widespread (so much so that it would spread to the Northern Territory); the Arctic Ocean to be ice-free by 2050; the extinction of the polar bear; and, my personal favourite, “China and Indonesia will be too hot to grow rice.”

Is CCS worth it?

This is interesting - a new paper that looks at carbon capture and wonders about the extra energy used in capturing and storing the carbon. If you use extra energy, you are releasing extra CO2, right?

Carbon Capture and Storage is being actively developed for deployment in fossil fuel power stations in an attempt to reduce future emissions of CO2 due to concerns about climate change. The deployment of this technology will cause an inevitable reduction in the overall efficiency of any electricity generation plant leading to an increase in demand for the fossil fuels used to power the generation process. This paper estimates the average reduction in generation efficiency caused by the imposition of Carbon Capture and Storage and considers its effects upon the depletion rate of global coal reserves. Future production of coal is modelled using a symmetrical production curve. The results suggest that the widespread adoption of Carbon Capture and Storage may result in the exhaustion of coal reserves several decades in advance of when this may happen if CCS is not deployed.

How to publish a comment

H/T to DI for this article by Rick Trebino, a physicist from Georgia Tech.

...in this article, I’ll share with you my recent experience publishing a Comment, so you can, too. There are just a few simple steps:

1. Read a paper that has a mistake in it.
2. Write and submit a Comment, politely correcting the mistake.
3. Enjoy your Comment in print along with the authors’ equally polite Reply, basking in the joy of having participated in the glorious scientific process and of the new friends you’ve made—

the authors whose research you’ve greatly assisted.

Ha ha! You didn’t really believe that, did you?

Generators

Given that it looks like the lights will be going out soon, it may be worth taking a look at one of these - a home generator:

Rolls Royce minds

A must-hear interview with Jill Duggan, the bureaucrat in charge of Britain's emissions trading scheme. The Australians who are conducting the interview are worried that perhaps an ETS is not such a good idea.

Having heard the interview you will understand why they feel this way - Duggan's performance is truly catastrophic, with our the woman from Whitehall apparently unable to quantify either the costs or the benefits of the scheme she runs. It's hilarious, toe-curling and utterly compelling.

These, ladies and gentlemen, are the Rolls Royce minds that run the UK these days.

Perverse incentives in the ivory tower

From the comments at Judith Curry's blog, a contribution from economist, Curt Doolittle.

The degree to which the academic scientific community in the west, since the 1970s has undermined scientific credibility is not understood in the incestuous circle of academia. To counter this effect: Write books not papers. Falsify your own work. Seek to justify opposing views. Ruthlessly attack others who undermine scientific credibility in the public debate. Reduce the number of graduate students and hide their work unless it is extremely well argued (this is a contrary incentive). It’s not about writing stories. It’s about doing good science. And right now, climate science is insufficiently articulated for human beings to justify paying the huge cost associated with the apocalyptic visions. Human beings are rational. They just need a rational argument and to understand the costs and benefits in relation to all their other costs and benefits.

The whole comment is worth a read.

I wonder where Sir Paul Nurse stands on the perverse incentives of academics?

The wind from Hawaii

Science has obtained statements from Eugene Wahl and Michael Mann regarding recent reports about the "delete all emails" episode. The major point of interest is that, Mann says that, contrary to some reports, he said nothing to Wahl, merely forwarding Jones' request to the AR4 delete emails:

Mann, reached on vacation in Hawaii, said the stories yesterday were "libelous" and false. "They're spreading a lie about me," he said of the Web sites. "This has been known for a year and a half that all I did was forward Phil's e-mail to Eugene." Asked why he sent the e-mail to his colleague, Mann said, "I felt Eugene Wahl had to be aware of this e-mail … it could be used against him. I didn't delete any e-mails and nor did I tell Wahl to delete any e-mails." Why didn't Mann call Wahl to discuss the odd request? "I was so busy. It's much easier to e-mail somebody. No where did I approve of the instruction to destroy e-mails."

Wahl confirms Mann's story in a separate statement.

I must say, I wasn't aware that Mann had added nothing. Does anyone know where this was revealed?

Paul Nurse on sceptics again

Paul Nurse was interviewed by journalist Charlie Rose recently. The video can be seen here, with a transcript on the same page. Much of the conversation is only of indirect relevance to readers here, but there are parts of the interview - when Nurse revisits the subject of scepticism - which are fascinating.

PAUL NURSE:  Science is important because it’s the most reliable way of gaining knowledge about the world and ourselves.  There’s something about science and the way we do it.  It’s to do with respect for observation and experiment.  So you don’t cherry pick data.  Half the problem with all the climate change debate .

CHARLIE ROSE:  Yes.

As if things weren't bad enough

The EU continues its efforts to deindustrialise the entire continent:

Europe's climate chief has beaten off intense lobbying from businesses to secure a key victory in the battle over greenhouse gas targets.

Connie Hedegaard, the EU climate change commissioner, published on Tuesday afternoon her long-awaited report into how the EU can toughen its climate targets in a cost-effective manner, with a proposal that the EU could raise its current targets on emissions cuts from 20% emissions cuts to 25% cuts by 2020.

I think this is going to turn out very badly.

Aiding and abetting

An article by Chris Horner looks at the question of whether Michael Mann was involved in deletion of emails during the aftermath of the IPCC's Fourth Assessment Report. Mann was apparently asked whether he was involved, directly or indirectly, in any such actions. His reply was that he deleted nothing.

Horner's point is that we now know from the investigation of Wahl that Mann was involved. As he helpfully paraphrases:

PSU: This is potentially very grave. We must know: Did you do A or B?

Mann: I did not do A.

PSU: Ah. There we go. It appears there is no evidence he did A or B.
