This film by the documentary-maker Martin Durkin presents the arguments of scientists and commentators who don't believe that CO2 produced by human activity is the main cause of climate change, rather changing radiation from the sun is the cause. It's a controversial film that was roundly attacked by some scientists and enthusiastically received by others, and the arguments it contains are an important part of the wider debate on the causes of climate change. Some have called "The Great Global Warming Swindle" the definitive retort to Al Gore's 'An Inconvenient Truth'. This program, hosted by Lateline presenter Tony Jones, introduces the controversial documentary. The screening is followed by an in-depth interview with writer and director Martin Durkin, followed by an expert panel discussion with a studio audience. The expert panel includes: Prof. David Karoly, Prof. Bob Carter, Robyn Williams, Michael Duffy, Greg Bourne, Ray Evans, Dr. Nikki Wiliams and Nick Rowley.
