Prof Alan Aylward: A sceptics' view of climate change
An Atmospheric Physicists look at debunking the sceptics.
The temperature record is fairly (though not entirely) clear, but most of the predictions leading on from this are based on numerical models, and I know as a modeller myself how complex these can be and how easy to get the answer you want or expect by the right combination of input and algorithm. So I end up being able to say: yes the climate is changing, but it has always changed. Is it caused by man? Well, maybe, but there are a lot more uncertainties than the 'establishment view' would have you believe. There is a bandwagon effect in science that we must beware of. That is not to say we should ignore the warnings we get about climate change: we should be a bit more wary about some of the conclusions we draw though.
