The fall and fall of Gish galloping Richard Tol's smear campaign

Sou | 6:42 PM 39 Comments - leave a comment

A short while ago I wrote an article demolishing Richard Tol's latest demonisation of Cook13, the well known 97% consensus paper.

"The consensus is of course in the high 90s" - Richard Tol

As you know, Richard agrees that of all the scientific papers that attribute a cause to global warming, the percentage that attribute it to human activity is "in the high 90s". Here is his confirmation at ATTP's blog:

Richard Tol says (my emphasis):

The consensus is of course in the high nineties. No one ever said it was not. We don’t need Cook’s survey to tell us that.
Cook’s paper tries to put a precise number on something everyone knows. They failed. Their number is not very precise.

So why does he think Cook13 failed, even though it "put a number" that "everyone else knows"? He doesn't say - anywhere.

How not to frame an FOI request - if you really want information

Sou | 5:06 PM 35 Comments - leave a comment

I don't normally bother too much with the denier blogger "Steve Goddard". Even among mainstream deniers he's viewed as shonky. However, something popped up at WUWT today (archived here) which is a great example of how deniers manufacture situations to suit their message, and how some disinformers (like Eric Worrall) misrepresent other deniers when it suits them.

This is what happened. "Steve Goddard" and someone I've never heard of, Kent Clizbe (a shady character), submitted an FOIA request to NOAA (the "Steve Goddard" version is archived here). They asked for a huge amount of information going back in history, minus the kitchen sink.

Deconstructing the 97% self-destructed Richard Tol

Sou | 1:38 AM 155 Comments - leave a comment

If you're a mediocre academic who yearns to be in the spotlight, what do you do? If you've burnt your bridges academically and cemented a reputation as a bit of a hack who isn't too fussed about accuracy.  If you aren't too worried that you'll end your lack-lustre career on a third-rate public speaking circuit, talking to a handful of doddering deniers in seedy back rooms of government buildings, then you might consider a career as a climate science denier.

That's the image that comes to mind when I consider the antics of Richard Tol over the past few years. Richard managed to snag a position as Professor of Economics at the University of Sussex in the UK. He specialises in the economics of climate, sort of, though he's had mixed success. That's mainly because he's not a detail person. He isn't too fussed when he lets mistakes slip through - unless, that is, someone catches him out.

Slowing ocean circulation prompts more Mann bashing from deniers at WUWT

Sou | 5:29 AM 62 Comments - leave a comment

Update: The Rahmstorf paper is getting more important by the minute. Now there are not one, not two, but three protest articles by Anthony Watts in the space of a few hours. You'll be surprised (probably not) that what Anthony thinks refutes the study actually lends support to it. See below.

Added by Sou 6:30 am 26 March 2015

There is a new paper in Nature Climate Change by Stefan Rahmstorf and others, which is getting a lot of protest from deniers. This signifies that it is potentially an important paper. Stefan has written about it at

What the research suggests is that the Atlantic Meridional Overturning Circulation (AMOC) may have slowed a lot in the late twentieth century (particularly between 1970 and 1990). This is attributed to the influx of fresh cold water, primarily from melting of the Greenland ice sheet.

A sensitive climate workshop - and freebies from the Royal Society

Sou | 3:45 AM 2 Comments - leave a comment

Some of you will know about the workshop on climate sensitivity that's taking place this week at Ringberg in Germany. The participant list includes some big names in the science world, and will ensure a wide range of views on the subject.

You can read about the workshop at, or visit the website.  You can also follow what's happening on Twitter, by searching #ringberg15. (There are some nuisance denier tweeters, but if you're on Twitter, you can just block or mute them and read what the scientists are tweeting.)

The workshop aims to get a better handle on climate sensitivity (and transient climate response), though I'm not all that optimistic that there'll be agreement on all counts. Here are the questions posed on the website:

WUWT strawman: Week 13 of 52 - not much extreme weather? So sez Anthony Watts

Sou | 5:22 PM 10 Comments - leave a comment

Anthony Watts, or one of his surrogates, has made a brief appearance at WUWT to write a headline and an opening salvo. Here is what he wrote (archived here):
So far, 2015 seems to be a bad year for the ‘severe weather caused by climate change” meme
Anthony Watts / 21 mins ago March 22, 2015
Looks like another “divergence problem” as tornadoes don’t follow the climatology

That's it. The rest was a copy and paste of an article from NOAA (archived here). The NOAA article was about how there have been no tornadoes reported in the USA this March, so far. This is a record - since 1970 at any rate.

Anthony Watts talked about a "meme", but what he wrote is a logical fallacy known as a strawman, as you'll see below.

Tim Ball recycling Medieval Warming conspiracies at WUWT

Sou | 7:39 AM 18 Comments - leave a comment

At WUWT, Tim Ball is pining for the good old days - twenty five years ago. He's written (again) about the medieval warm anomaly and wishing it was global (archived here). I don't know why he harps on about it so. I think it's an excuse to name drop - he says he once met up with Hubert Lamb and he tells everyone so at every opportunity. He likes to pretend they were bosom buddies, though I doubt Hubert Lamb would have remembered Tim Ball, even had he met him.

I've written about the medieval warm anomaly on previous occasions - here and here and in some detail here, for example. There's really not that much more to be said, so I'll just repeat what I've written on another occasion when Tim moaned about the MWP:

Another conspiracy theory at WUWT - birthers and more

Sou | 5:39 AM 6 Comments - leave a comment

Anthony's still pretty well AWOL. Meanwhile the conspiracy theorists are hard at it. This time it's Eric Worrall again - that is, Eric "eugenics" Worrall to those who aren't familiar with the name.

Someone started a rumour that President Obama had bought a beachfront property in Hawaii. Not just any property, it was the property used in Magnum PI - a television show from way back when starring Tom Selleck.

The rumour was quickly squashed, on both CNN and Fox News. However no-one bothered to correct the WUWT article itself (archived here). Why spoil a good rumour with facts?

As many people know, WUWT is a climate conspiracy website mainly, but it's not averse to a bit of birtherism and it most certainly panders to all those to the right of the extreme right. Given the USA has no leftist politics to speak of, the best WUWT can manage is to take a shot at centrist politicians like President Obama. And why not toss a bone to all the WUWT conspiracy nutters when the opportunity presents itself?

Roy Spencer PhD and Steve "mad, mad, mad" Goreham on defying laws

Sou | 11:52 PM 11 Comments - leave a comment

Deniers are making hay while the sun beats down - or the little mice are playing while the boss is off doing something or the other.

As I've commented before, Anthony Watts has all but disappeared from WUWT recently. While he's gone AWOL, there are a lot of deniers using his blog to peddle their denial.

Yesterday it was David Middleton who seems to be a greenhouse effect denier. Today it's Steve "mad, mad mad" Goreham, who is employed to reject climate science. It's his job. I've just noticed that he is the Executive Director of one of those pretty well one-man bands that pretends to be a real organisation by giving itself a fancy name and building a website.

David Middleton calls on denier consensus to deride scientific consensus

Sou | 11:14 AM 7 Comments - leave a comment

While Anthony Watts is taking a break he's handed over his blog to other deniers. One of these is a bloke called David Middleton, who has written two articles in the past few days. He's all over the place with no coherency, dredging up one denier meme after another.

Today his article is as scatty as any other (archived here). I gather that he's a greenhouse effect denier because he is madly trying to reject the fact that human emissions of greenhouse gases have caused the world to warm.

One thing that you'll notice if you bother to wade through his nonsense is that he objects to the fact that all the science points to the cause of the recent global warming. He complains a lot about scientific consensus. One of his main arguments against scientific consensus is that a lot of petroleum geologists and engineers (not climate scientists) from Alberta are climate science deniers. (I've written about that study before.) For example, he wrote:
So, it should come as little surprise that geoscientists have consistently been far more likely to think that modern climate changes have been driven by overwhelmingly natural processes…

He also called on the AMS survey I've also written about before, where a lot of US meteorologists - not researchers - basically weather announcers - rejected climate science.

In other words, David calls on consensus among deniers to refute consensus among scientists.

Did I say that climate science deniers are consistently inconsistent?

Incidentally, David Middleton misrepresented both studies, which is par for the course for deniers.
