I’ve recently watched the film AN INCONVENIENT TRUTH, directed by Davis Guggenheim, featuring Al Gore.
I’d highly recommend watching this film. I found it really moving. Here is the Wikipedia entry for the film, including quite a few opinions from film critics. Trying to normalise away any potential political spin here, Al Gore seems like a nice guy who actually cares. And indeed one who knows his stuff.
A few film critics accuse the movie of skewing the data, however I’ve attended several seminars on climate change recently, and the results reported in those seem to agree with what was presented in the film. They all seem to paint a similar picture.
‘Nine errors’ have been pointed out in the film, points used for impact which are unsupported by current scientific studies. This news report gives a good summary. The film is allowed to be shown in schools as long as ‘guidelines’ documenting and explaining these errors are included.
The film gives some useful information and tips at the end, and believe me even if you *think* you’re being green, you could probably improve on it tenfold. The film has seriously made me consider buying a hybrid car.
On a slightly unrelated note, the film also demonstrates how to essentially make a movie out of a seminar consisting of a slide-show presentation. It works really well and keeps the audience attentive. I think this is generally a good way of presenting physics/scientific ideas.
