Beginning with the lack of increase in global temperatures for fifteen years - during a period when CO2 in the atmosphere has grown steadily - he then critiques the poor science, the IPCC and above all, the lobby which has captured today's political leadership. The article can be read in full here. Sillars has expressed scepticism previously, for example in this 2010 Scotsman letter.
The response to the article in the Scotsrenewables blog is disappointing for its failure to debate or even address the points articulated by Sillars. Read it here. Allow me to fisk it (ignoring the ad hominems).
- 'He (Sillars) refers to the current scientific consensus on AGW as a ‘lobby’, which is like calling the SNP a ‘minority interest group in Scotland’ The AGW lobby is nothing like a 'minority interest'. The point Sillars is making is that their power is based on lobbying - not science. It is very difficult these days to maintain that there is an AGW scientific consensus - if there ever was. There have always been dissenters such as Prof Richard Lindzen of MIT. It is just that they were marginalised by very powerful lobbying - of which there is increasing and damning documentary evidence.
- 'Sillars claims that climatology is ‘in its infancy’ - a particularly stupid statement when you consider the likes of Edmund Halley, who published a map of the trade winds in 1686. . . ' This portrays the view that climate scientists know more than those who went before therefore are mature. A more humble approach would be to acknowledge that, in the complex area of climate science, present knowledge is in its infancy. Scottishrenewables cites models as an evidence of maturity. That just fails to acknowledge the point behind Sillars' initial paragraph. Models have been confounded (especially of late) by measurements. The faith in models to the detriment of observational science is one of the scandals of modern climate science.
- ' Sillars speaks of a ‘delusional world where they believe they . . . can stop the world’s climate warming beyond another 2.5 degrees’ – so apparently he DOES he believe in climate change, but believes action is futile.' Dear Scottishrenewables, please note Sillars was referring to a 'delusional world' as you actually quote! Nowhere does he say he accepts climate change of a 'disruptive' to 'threatening' nature - the scale you use. Your creation of a clumsy straw man diminishes your comment.
- 'So – all in all remarkable double whammy own goal from a man who is allegedly a lifelong supporter of independence . . . ' Ignoring the ad hominem attack, why do the views of Sillars on this issue need to be vindicated or otherwise by his views on other matters? I think I disagree with him on a number of issues but I respect his views on this issue because they seem to me founded on a clarity of thought and evidence.
- ' . . . but who just can’t miss a chance to get back at old adversaries, no matter what the cost to his country and his planet.' Much of your response is based on a priori assumptions which are not a good basis for debate and discussion. There is now a wealth of evidence out there to challenge the basis of the belief system you exhibit. I invite you to consider The Hockey Stick Illusion and then the Delinquent Teenager (about deficiencies in the IPCC). You have to be able to deal with these critiques in order to credibly defend your assumptions.
