Another open letter to James Delingpole
James Delingpole is almost as difficult to engage in debate as Lord Monckton; but not quite – at least I have had several exchanges of emails with Monckton. His Lordship may be equally as fond of facile sarcasm but at least he keeps up a pretence of being capable of debate. Delingpole is just sarcastic; and will not engage in debate with anyone who understands the science – let alone an actual climate scientist. But after being intellectually raped by Sir Paul Nurse, who can blame him? Still, I do wish he would shut up… This is a transcript of my latest attempt to get his attention (still visible here on his personal blog). However, he seems to be too busy over on his Telegraph blog debating the significance of more important political questions of our times such as: Has George Osborn has ever eaten a Cornish Pasty?…
I know you will cite the Met Office as being part of some anti-libertarian plot to install worldwide Socialist governance but, will you please do us all a favour and suspend your belief in conspiracy theories just long enough to take on board some new information:
“A project running almost 10,000 climate simulations on volunteers’ home computers has found that a global warming of 3 degrees Celsius by 2050 is ‘equally plausible’ as a rise of 1.4 degrees. The study addresses some of the uncertainties that previous forecasts, using simpler models or only a few dozen simulations, may have over-looked. Importantly, the forecast range is derived from using a complex Met Office model that accurately reproduces observed temperature changes over the last 50 years. The results suggest that the world is very likely to cross the ’2 degrees barrier’ at some point this century if emissions continue unabated. It also suggests that those planning for the impacts of climate change need to consider the possibility of warming of up to 3 degrees (above the 1961-1990 average) by 2050, even on a mid-range emission scenario. This is a faster rate of warming than most other models predict.”
Citizen science looks at future warming uncertainty.
N.B. The ability of these computer models to recreate historical trends over the last 50 years is not evidence of fudge factors having been applied: It is evidence of model validation, which – along with calibration and sensitivity analysis – is an integral part of establishing the accuracy of such modelling techniques. You can – or should – trust me on this because, unlike you, this is what I have been doing for the last 20 years or so (i.e. using probabilistic computer modelling in environmental risk assessments).
Your beloved marketplace of ideas is a dangerous fallacy; of which your success in getting your ill-informed unscientific opinions plastered all over the media and infecting people’s minds is profound evidence. And for what purpose? You may think you are acting in the public interest but, unfortunately, like everything else in Watermelons 2.0, this is an inversion of reality: As Peter Jacques (University of Florida) has pointed out, it is precisely because environmental scepticism is not in the public interest, the tobacco industry invented the sound science versus junk science debate (now being used to great effect by the fossil fuel and energy industry) to confuse people and prevent sensible regulation of their product.
