An Inconvenient Truth, a feature film starring former vice-president Al Gore as Al Gore giving his PowerPoint presentation on climate change, opens in New York and Los Angeles on 24 May and elsewhere throughout the summer. News@nature.com tackles the big questions surrounding this much talked-about film.
Climate-change scientists who have seen it say that the main thrust of the presentation is correct, although they do disagree with details here and there. Some of his more melodramatic moments might make those used to the cautious language of scientific papers a bit uncomfortable. The wretched chaos in New Orleans after Hurricane Katrina gets a lot of screen time, for example. Most climate scientists are very scrupulous about explaining that individual hurricanes can never be said to be ’caused’ by global warming, although climate change may tend to increase storm numbers or severity. Gore never actually makes a causal link, but a lay viewer could easily infer it.
