Alfred Albert "Al" Gore Jr. is the co-winner of the 2007 Nobel Peace Prize. Experts give their opinions:
Gjermund Hagesaether, of Norway's Progress Party: "We believe it is strange to give the prize to Al Gore for having made a film on climate that is subjective, one-sided and full of one-sided assertions."
Award-winning French geochemist Claude Allegre: "The amount of nonsense in Al Gore's film! It's all politics, it's designed to intervene in American politics. It's scandalous."
Dr William Gray, a pioneer in the science of seasonal hurricane forecasts: "We're brainwashing our children. They're going to the Gore movie and being fed all this. It's ridiculous. We'll look back on all of this in 10 or 15 years and realise how foolish it was."
Dr. Gray added: "It bothers me that my fellow scientists are not speaking out against something they know is wrong. But they also know that they'd never get any grants if they spoke out."
Czech President Vaclav Klausa: "[I'm] a bit surprised that Al Gore has received a peace prize because the connection between his activities and world peace are vague and not very clear."
