There was a documentary on television last year - The Great Global Warming Swindle - that had a huge impact on the public, persuading many people that man-made climate change is not taking place.

I found it slightly disturbing that anybody, whether they believed that man-made climate change was taking place or not, would go to so much effort to convince us that going green is a complete waste of time. Well, it turns out that irony of ironies, the programme itself was a complete swindle, and that many of the 'experts' that featured on it had been directly funded by fossil-fuel companies.

This article explains in detail, and is well worth a read if you have a few minutes.
