The great economist Joseph Schumpeter once said, "The first thing a man will do for his ideals is lie."
The Times of London reports that Al Gore thinks the latest research shows that the Arctic could be completely ice-free in five years.
In his speech, Mr Gore told the conference: "These figures are fresh. Some of the models suggest to Dr [Wieslav] Maslowski that there is a 75 per cent chance that the entire north polar ice cap, during the summer months, could be completely ice-free within five to seven years."
But, oops! The climatologist whose work Mr Gore was relying upon disputed this. "It's unclear to me how this figure was arrived at," Dr Maslowski said. "I would never try to estimate likelihood at anything as exact as this."
Gore has a lot of money tied up in the theory of global warming; sometimes this makes it hard to stick to the facts. Exaggerating claims can easily be justified when one stands to benefit financially.
