The film’s claim that solar activity might account for recent warming is also without credibility. In September 2006, the Times reported the latest findings from researchers writing in the top journal, Nature: “Scientists have examined various proxies of solar energy output over the past 1,000 years and have found no evidence that they are correlated with today's rising temperatures. Satellite observations over the past 30 years have also turned up nothing. ‘The solar contribution to warming... is negligible,’ So we're once again back to an understanding that the Ice Ages ended because cavemen wouldn't swtich to biodiesel to power their SUVs.
