A scientist speaks out

Alas, Alcoa is just one of many large corporations that have succumbed to the growing politically correct hysteria over man-made global warming. President John F. Kennedy was right when he observed, "The great enemy of the truth is very often not the lie -– deliberate, contrived, and dishonest –- but the myth –- persistent, persuasive, and realistic."

Despite the fact that many scientists offer evidence that counters the theory of man-made global warming, many stubbornly believe it's true. One scientist who is challenging the idea that mankind has contributed significantly to climate change is David Evans of Australia.
