7.4 Closing thoughts

Of course, doing anything about this needs scientific evidence and understanding, but it also requires social, economic and technological changes, which can only be achieved through political will. If you want to explore some of the broader context, a good place to start would be the New Internationalist issue 357, ‘The Big Switch: Climate Change Solutions’ at New Internationalist.

Faced with the sort of predictions climatologists are making, is it sufficient for science teachers to stop at the ‘science’, or should we be tackling some of these broader issues in schools?

If you want to find out more, the Hadley Centre is the UK's foremost climate research centre and provides a lot of useful information, as does the Intergovernmental Panel On Climate Change at IPCC.

To help you understand some of the key factors in climate modelling, click on the link above to work through a simplified simulation.

In reality, climate modelling is extremely complex, because all the variables are not known. The ability to develop mathematical models of climate change is constantly improving, but there are still many competing models, each making different predictions of how the climate will change. All models, currently, show a significant increase in the global mean surface temperature attributable to human influences.
