In this third and final part Dr Iain Stewart looks at the biggest challenge now facing climate scientists. Just how can they predict exactly what changes global warming will bring? It's a journey that takes him from early attempts to model the climate system with dishpans, to supercomputers, and to the frontline of climate research today: Greenland. Most worryingly, he discovers that scientists are becoming increasingly concerned that their models are actually underestimating the speed of changes already under way.

This is a very controversial topic and this film does a good job of presenting both sides of the argument and justifying the investigative journalist's stand with analytical data.
