In the final programme of the series Dr Iain Stewart looks to the future and climate modelling. He starts in the past and early methods of climate modelling using a bowl of liquid and a Bunsen burner. Dr Stewart shows that the advent of computers allowed more sophisticated modelling. The programme shows that James Hansens computer model was proven correct when a volcano eruption changed the climate for a number of years, reducing the temperature by half a degree in the US and Europe.
The predictions for the future are for gradual warming, but what the computer models can not predict is an unforseen catastrophic change, the sort of cange that is recorded in the Greenland ice core records. The possibility exists that a massive sudden change could occur since this has happened in the past.
If you are interested in learning more about climate change, then you might like to attend Dr Iain Stewarts talk at the Turner Sims Concert Hall , Southampton University on Tues 21 October.
