With the big freeze on it is of course a good time to talk about global warming.
In particular I want to criticise an idea that is promoted mostly by people with who I agree 90% of the time- that global warming is a 'scam', a 'hoax' or a 'con' or whatever. It is possible that global warming is an incorrect theory, however the idea that thousands of scientists are colluding to trick the public and politicians is absurd. It requires a conspiracy that is in size equal to the one posited by the 9/11 truthers, involving a vast number of people to keep the secret.
Even people who are highly sceptical of the environmental movement such as Bjorn Lomborg or Ian Murray accept that having looked at the evidence, man made global warming is real.
I suspect that the scepticism about global warming is because of a number of things.
The fact that most environmentalists are watermelons, green on the outside red on the inside and seek to use it as an excuse for imposing their political beliefs. This is true and a lot of left wing types use the environment as an excuse to promote statist solutions involving vast amounts of state control over our lives and appear hostile towards solutions that don't involve radical changes to the way we live. However they also propose vast inefficient socialist solutions to the recession, but that doesn't disprove the existence of the recession. I'm sure if a comet was heading straight towards Earth their solution would involve socialism.
Secondly a lot of lazy scientists attribute everything to global warming. So for example if the oceans are becoming less salty then climate change is to blame, yet when it turns out that actually oceans are getting more salty not less, global warming is still responsible. This is unfortunate bu again doesn't say much about the science behind AGW.
Many advocates of AGW exaggerate or make up stuff to bolster their case. The Gore effect. This is true but again doesn't explain why so many people sceptical about environmentalism also believe it. Besides which many opponents of AGW also make up stuff so it doesn't really provide a basis on which to support a policy or not. That's what people do they make up stuff.
Many advocates of AGW behave in a manner inconsitant with their stated beliefs, think of Bono booking a flight for his hat or Al Gore's collosal energy consumption. Again this is true but proves that some people are hypocrites, or just want the solutions to involve restrictions on the little people. It doesn't say anything about the science.
