From the article:"This is a dazzling debunking of climate change science. It is also wildly wrong... In keeping with most of the articles about climate change in [the Sunday Telegraph], it is a mixture of cherry-picking, downright misrepresentation, and pseudo-scientific gibberish. But it has the virtue of being incomprehensible to anyone who is not an atmospheric physicist... As for James Hansen, he did not tell the US Congress that temperatures would rise by 0.3C by the end of the past century. He presented three possible scenarios to the US Senate high, medium, and low. Both the high and low scenarios, he explained, were unlikely to materialize. The middle one was 'the most plausible.' As it happens, the middle scenario was almost exactly right. He did not claim, under any scenario, that sea levels would rise by several feet by 2000."
