I agree with those who say that Al Gore's film, An Inconvenient Truth (p4), is a "dodgy dossier" on climate change. Even the explanation of the basic science is flawed. In the third scene, for example, global warming is wrongly conflated with the enhanced greenhouse effect.
By spinning what little science there is in his film, Mr Gore risks damaging the credibility of science; thankfully, no scientist is screened endorsing what he says. Surely our pupils deserve to be taught by subject specialists, not politicians via DVD.
Screening Channel 4's The Great Global Warming Swindle in schools could go some way to restoring some balance. At least the story is told by real and eminent scientists. They simply offer an alternative explanation for global warming, with a better fit to the temperature record.
