Sceptics
Some scientists disagree with the global and UK predictions for climate change, mainly because the climate had changed naturally before. In addition predicting changes to our climate is very complex and the use of computer models has raised some criticism.
On top of that, some experts believe it is impossible to be certain about how our climate will change as it can be very unpredictable. They also believe, the climate is supposed to change and it has done before. Many believe activities from humans can not be to blame for changes in the climate. Some sceptics have criticised the reports of the IPCC as being based on unknown assumptions about the future and based on computer models which are not adequate for such a job.
Emeritus Professor of Biogeography at the University of London, Philip Stott summed up his thoughts on the issue in a newspaper article in 2005.
鈥淐limate change has to be broken down into three questions: 'Is climate changing and in what direction?' 'Are humans influencing climate change, and to what degree?' And: 'Are humans able to manage climate change predictably by adjusting one or two factors out of the thousands involved?' The most fundamental question is: 'Can humans manipulate climate predictably?' Or, more scientifically: 'Will cutting carbon dioxide emissions at the margin produce a linear, predictable change in climate?' The answer is 'No'. In so complex a coupled, non-linear, chaotic system as climate, not doing something at the margins is as unpredictable as doing something. This is the cautious science; the rest is dogma.鈥
