Disagreeing with climate science is so 6 months ago, right? Unfortunately, there’s still political characters (in this case, ex-political) like Nick Minchin spouting off on Q and A, Tony Abbott saying it was warmer when Jesus was kickin’, and the Rudd government is refusing to go to an election with climate as a major issue (apparently they used up their environmental credibility in the ’07 election).
One of the most commonly repeated criticisms of climate science is the reliance on computer models. The image that springs to mind of a ‘computer model’ for many is a simulation showing a pretty picture based on what someone wants it to show. In actual fact, climate science doesn’t all depend on computer models, and even with simple models which use computers to do the grunt work, as Tamino explains at Open Mind. The article seems a bit dense at first, but it’s not actually heavy going and it shows well how we know that human-induced greenhouse emissions are responsible for recent warming.
