Dr Mann in the dock - Josh 388

On this historic Brexit day the fun has not been confined to this continent. Over in the US they have had a 'hearing' on Climate Science with three of the world's most eminent climate scientists. Michael Mann was there too. 

Worth watching (nearly) the whole thing.

Loved the " ..... with three of the world's most eminent climate scientists. Michael Mann was there too."

I would hope that my views on this subject were well known on BH however it is obvious that Mann was a far better communicator than the other panel members :(
I thought in particular that Judith came over as scatter brained and vague, I speak as I find as usual.

The best line was Judith's last in her oral testimony. "Let's make climate science great again." Trumped everything else.
Happy Brexit day, Josh.

To the utter dismay of the Chairman, the attending Representatives reckoned the final score as roughly Mann 97, the Usual Suspects 3.

Watch the whole thing ,and you can judge how well science works when allowed to.

The problem is that there are two types of testimonies. Honest ones that articulate the uncertainties and Mann who brazenly lies through his teeth at every opportunity. That's why he sounds impressive and solid.

Science is drowning in a oil slick of dishonesty.

"Most scientists 'can't replicate studies by their peers'

"Richard Horton - editor of The Lancet.

The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue".

You need a new echo chamber- this one was shattered earlier today by a few hours controversy in a public fourm.

Link to written testimony from all four witnesses. This is what they read out during the session, before the Q&A started.

Mann's testimony whines about "Science critics will therefore often select a single scientist to ridicule, hector, and intimidate" before doing this to Curry, "Bates’ allegations were also published on the blog of climate science denier Judith Curry".

Pielke's evidence talks about the lack of any evidence of trends in hurricanes, floods etc, and there's an appendix with data and IPCC statements about this. He also talks about the Grijalva witch-hunt.

Mar 30, 2017 at 9:08 AM | Registered CommenterPaul Matthews

Mann's testimony is stomach turning;
First look at all my awards- the appeal to authority
Then he as the "victim" - I'm in a minority here whereas in the "real world" there is the 97% consensus
This is followed up by the "vested interests" argument linking fossil fuels to "big tobacco" denial.

And so it goes on.
Man is a genius, but not at science, but at grandstanding and twisting the facts.

I fear Josh was looking in the wrong direction whilst clutching his crayons. Here's my own initial take on yesterday's proceedings:

The House Science Climate Model Show Trial

It reproduces several paragraphs of Mike Mann's written testimony, plus a picture of Dana Rohrabacher about to explode. At just that moment my YouTube feed inexplicably cut out.

Coincidence? I think not!

Mr Hunt, you do seem to have misread the terms of the question and answer session: "An invitation has also been extended to the Chief Scientist, CSIRO Chief Executive and staff, and the Director of the Bureau of Meteorology to attend and engage in these discussions." Are you any of these persons? Also, you seem to misunderstand the principle of “free speech” (to use your scary quotes): yes, you may say what you want in public… but, would you define someone’s personal web site as “public” or “private?” Facebook does give you the options of preventing others from viewing or contributing to your site, so a fair assumption is that it is “private.” Similarly, you have full discretion to “moderate” comments on your own site – are you inhibiting free speech should you choose to moderate?

Considering that the Arctic was forecast to be clear of all ice by the summer of 2013, hindsight does show that it seemed to have been over-optimistic/pessimistic*. Ah, well… at least it keeps you entertained/employed*.

If it's any comfort to you I'm blocked by Mann as well. I figure he must have some sort of automatic blocking software, assuming some such thing exists.

Michael Mann has just been given about 10 minutes of airtime on the Radio 4 Inside Science program. Worth listening to if you want to form a strong opinion about the BBC.

Why, thank you, Mr Hunt! So flattered you remember me! (And I do hope the memory is good. Also, while flattery is very nice, I do prefer cash…)

Anyhooo… that is all an aside, and we should not wander too far off-topic; however, you do highlight that Mr Mann is demonstrably not habituated to upholding the truth – he denied calling Dr Curry a denier, yet the quotation of his that you offer contains the very words: “…climate science denier Judith Curry…” Indeed, the above link does uphold the view that Mr Mann’s words should constantly be viewed with suspicion. He also has claimed to be a joint Nobel Prize winner: it being shared, did he get the Nob-end, or the Bel-end?

Sadly, I am not a scientist, so cannot call on my authority, however, I do think that I am capable of scientific thinking, and a key element of that is scepticism – and that means scepticism about everything, including my own observations, summations and conclusions. Mr Mann’s (and others in that clip) opinions are that there is incontrovertible evidence that humans are responsible for the present climate change – until this evidence is presented to me, I will remain sceptical of that conclusion. A single volcano popping off can incontrovertibly cause climate change within a few days, and a change that can last for weeks or even years; yet the Earth eventually reverts back to what we considered normal. In my (perhaps simple) mind, this shows that human efforts trail a long way behind Mother Earth, and that Mother Earth is a lot more resilient than we are giving her credit for.

Mar 30, 2017 at 10:16 PM | Registered CommenterRadical Rodent

Looking up Laden’s biographical details, I find that his background is in anthropology, and he has taught this subject at several universities. He has also been or is currently a free-lance science writer, with several articles in the Smithsonian magazine. All this I find estimable and, indeed, rather impressive. Similarly, I assume that Russell Seitz has had a worthy career as professor in a university physics department. And I suspect these cases are representative. So many people with better-than-average talents leading reasonably productive lives, performing useful tasks in society …

And then the gods set them a test – in the form of a new scientific doctrine. And perhaps because there was some flaw, some critical deficiency hidden within their outwardly impressive personalities, they have failed that test. Not only that; they have done so in a quite spectacular fashion – in part, I suspect, because they couldn’t imagine such a thing ever coming to pass. In fact, they have failed to such an extent that in some respects they have been turned into a force for evil.

And as part of the test, the gods sent them Michael Mann. And in a move that is reminiscent of the way that 19th century Frenchmen made Esterhazy a Hero of France, they have transmogrified him into St. Michael, a martyr for science.

In a word Hosers

Good to have you back Ayla!

Climate Scientists needs to wage a war that they can win for a change. How many of Skeptical Science's atom bombs of heat need to be dropped within the Arctic Circle, to get rid of that Inconvenient Ice, and those pesky Polar Bears that keep reproducing, as Climate Science keeps failing to reproduce Mann's Hockey Stick?

Hockey Stick reproduction has been a dismal failure of Climate Science evolution, and extinction is imminent. Mann should receive a Darwin Award, for failing Climate Science development.

Climate Science might have achieved something useful, but for the Hockey Sticks rammed up their emissions ouput.

It’s amazing Mann sticks with Mann et al 1999 which features in his written testimony along with the familiar refrain: “… we have now broken the all-time global temperature record for three consecutive years …” as if that is somehow significant, considering the records go back only about 150 years at the most.
Even Mann et al 2008 shows that the NH temperature at the start of the instrumental record was the coldest in at least 1800 years (LIA) while the Greenland ice core proxies (GISP2) show the LIA was near the coldest since the Younger Dryas, or in around 10,000 years.
What would he and his claque have preferred, the GAT to drop even further?
Amazing also that he still gets away with heavily overlaying the supposed instrumental record up to 2008 (in red) which is pure propaganda intended to fool the ingenuous and is very wrong statistically and scientifically.
Nowhere in his written testimony does he attempt to address the attribution problem, in fact nowhere does he even mention ‘carbon dioxide’ or the symbol ‘CO2’.

I think we should give thanks that this House Committee was graced with the presence of Dr Mann, the foremost, leading climate scientist and Nobel Laureate. In this meeting he was able to finally demonstrate, without fear of contradiction, that:

Today's temperatures are hotter than any time since 1000 AD. The Medieval Warming Period did not exist, and neither did the Little Ice Age, as proven by Dr Mann,
There has been no pause in global warming,
The predicted, Tropical Troposphere Hot Spot has been demonstrated
Global warming is causing increasing numbers of floods, as proven by Dr Mann,
Global warming is causing increasing hurricane activity as proven by Dr Mann,

And that throughout his long career he has behaved impeccably at all times, fostering a spirit of investigative, inclusive scientific thought and discussion.

Dr Mann clearly serves as a role model for all aspiring climate scientists.

Mar 31, 2017 at 10:12 AM | Unregistered CommenterCapell

I’m sorry, Mr Hunt, but you are not applying any scientific rigour to your own observations – the facts have been presented to you that Mr Mann has lied in congressional (or whatever they are – pretty high-powered, though) hearings at least twice, yet you refuse to acknowledge that. These facts are presented in as many forms as possible over this interwebby thingy; short of being grabbed by the scruff of the neck and having your nose rubbed in them, how can you not see what everyone else can? Is it that it impinges upon your devotion to this shady character? Or are you unable to do anything but deny everything that blatantly contradicts your dearly-held beliefs?

Given your resistance to even the mildest form of scepticism about this debacle, how can we accept that you are a scientist, let alone one of such stature which you seem to portray yourself as?

Mar 31, 2017 at 10:41 AM | Registered CommenterRadical Rodent

Many a true word spoken in jest, Capell. Notwithstanding the fascinating debate about whether a being called a climate science denier is the same as a climate change denier, Christy's bogus chart is eviscerated here and here.

Interesting that everyone testified that is AGW is likely to be a big problem.... [2.01.30]

Mar 31, 2017 at 12:19 PM | Unregistered CommenterPhil Clarke


Your second evisceration leaves me somewhat bemused: the author is trying to claim that the average value of the models is not the same thing as the observed temperature readings (which are themselves arrived at by statistical manipulation of hundreds of temperature observations) . . . .
Sorry, I didn't come down with the last shower, and that argument is rubbish.

everyone testified that is AGW is likely to be a big problem....

well, that's just awesome. But as Christy pointed out, the models work just fine if you take carbon dioxide out of any consideration. So we might have a problem, but it seems likely that it's not down to us and there's little we can do about it other than mitigate the effects.
