Different visions for global warming: a joke or extinction?

Meteorologist Augie Auer is quoted: "It is time to attack the myth of global warming (...) We're all going to survive this. It's all going to be a joke in five years."

According to Auer, water vapour is responsible for 95 per cent of the greenhouse effect. Greenhouse gases other than water: carbon dioxide, methane, nitrogen dioxide, and various others including CFCs, contributed only five per cent of the effect, with carbon dioxide being by far the greatest contributor at 3.6 per cent. BUT carbon dioxide as a result of man's activities was only 3.2 per cent, so man's contribution is 0.036 X 0.032 or 0.1152% of the problem.

Meanwhile, Leonardo DiCaprio has made a film, the 11th Hour, warning that human beings face extinction as a result of the environmental crisis.

Remember the movie "Chain Reaction" with Keanu Reeves and Morgan Freeman? Bubbles created by sonoluminescence have been observed generating temperatures measuring in the kilokelvins, or tens of thousands of degrees. The temperature threshold to initiate nuclear fusion reactions is in the millions of degrees, or megakelvins. There is a bit of a discrepancy here, a discrepancy adding up to three orders of magnitude. Sonoluminescence is hot, but it's not that hot.

wisegeek reports that a patent application by R. P. Taleyarkhan was rejected.
