Richard Lindzen attacked for dissention

Rather than substantiating the weaknesses in their own case, the climate community is continuing their attack on the dissenters. The latest is in the New York Times on Prof Richard Lindzen of MIT. I have posted the following on Prof Roger Pielke Jnr’s blog

Having listened to some of Prof Lindzen’s speeches and read some of his more populist articles, this attack on him leaves out 2 things. First, it omits one of his favourite words “feedbacks”. Second it leaves out the scale of the difference. Lindzen claims agreement with mainstream scientists that a doubling of CO2, on its own, would raise temperatures by around 1.2 celsius. Whereas Lindzen claims evidence that cloud “feedbacks” more than halve the impact, the consensus of climate models such positive feedbacks of up to three times – with wide variation. The evidence supporting this is patchy, a message implicitly admitted in the article. The lack of substantiation in this key area is crucial. If makes the extreme warming claims uncertain. If one the looks at the expected economic costs of “doing nothing” (like the Stern Review) this uncertainty in the projections should carry a risk weighting.

As a comparison, I would direct readers to Prof Lindzen’s talk at the House of Commons in February of this year. On Youtube, a response here, and Lindzens rebuttal reply at the GWPF.

When the main effort is on silencing dissent, rather than substantiating their own case, it implies to me that the climate consensus has a weak case – and they know it.

    Shameless bilge. The Grey Lady is well into her dotage.
