Dr Scott Denning – an excellent speaker.

We have recently looked at speeches from International Conferences on Climate Change as staged by the Heartland Institute. I had read that Heartland, although being essentially sceptical on the subject, nevertheless issued speaking invitations to scientists espoused to the warming orthodoxy. This in contrast to warmist organisations that routinely exclude sceptics on the grounds that ‘the debate is over’. Speaking personally it was precisely the ‘Science is Settled’ approach, and the debate suppression thus implied, that alerted my suspicions several years ago. If it’s science it’s not settled: if it’s settled it’s not science. (That, by the way, is a chiasmus.)

I was delighted to find that on 7 July, 2011, Heartland had staged a Debate at their Sixth International Conference. Scott Denning had debated with Roy Spencer. We shall look at Spencer in a future posting. Today let’s watch Denning.

On the YouTube posting we are not told who creates the civilised decorum for this debate with his well measured introduction, but after some ferreting I believe it to be James Taylor. If I am wrong I hope both he and whoever it was will forgive my error. By the way, he announces that he will be a stickler for time limits. I wonder whether this means that since the 2009 Conference the Institute has installed a clock. If you read my critique on the speech by Christopher Booker you will know what I mean.

Denning speaks from 3:40 till 14:40, and immediately declares himself a skeptic (I have to spell it the transatlantic way because that is how the word appears on his slide). He explains that everyone, scientist or lay, should question all scientific assertions. This is music to my ears, and is clearly intended to resonate well with his audience.

He speaks in simple, clear, uncomplicated sentences without overtly speaking down to his audience. He shoots it from the hip. Already I am enjoying this.

I enjoy it even more when he shows he is prepared to make a fool of himself. He wants to show how molecules vibrate, so he moves his body and makes silly noises to demonstrate. He first does it at 9:07, just as the camera frustratingly cuts away; but be patient. The camera cuts back to him at 9:32 just in time for us to witness the best bit of foolery. How much does he add to the wisdom of ages by such behaviour? Not a lot, but rest assured that everyone in that audience will remember the speaker who did that. If you are due to be one of several speakers at a conference I invite you to bear the thought in mind.

Anyone who has looked beyond sensational tabloidesque headlines on this subject knows that the greenhouse properties of CO2 are commonplace in the climate issue. Where the argument actually rages is in the amount and direction of feedback from consequent water vapour. Therefore Denning’s histrionic clowning to illustrate the way carbon dioxide captures warmth, and indeed most of his talk, is pushing against an open door and ignoring the big question. No matter: be assured that question is raised during the next section of this debate – during the majority of this video that is beyond the brief of this posting.

Meanwhile, within my brief is the conclusion that Dr Scott Denning is an excellent speaker.
