Gore doesn't like it when he's questioned

Lindzen is viewed by some as one of the nation's foremost climatologist. Unlike Gore - whose movie and slide show have been rife with error - he knows what he is talking about, probably a major reason Gore won't debate him. Lindzen years ago did about $10,000 worth of work as a witness for fossil-fuel companies. There was nothing wrong with that, and he clearly was not corrupted by it.

Whatever Gore believes, the global warming debate is not over, but what should be over is waging it as an ad hominem contest in which science itself is hurt along with scientists whose arguments should be weighed on their merits.

American Thinker: The Coming Ice Age

Earth's climate is controlled by the Sun. In comparison, every other factor is trivial. The coldest part of the Little Ice Age during the latter half of the seventeenth century was marked by the nearly complete absence of sunspots. And the Sun now appears to be entering a new period of quiescence. August of 2008 was the first month since the year 1913 that no sunspots were observed. As I write, the sun remains quiet. We are in a cooling trend. The areal extent of global sea ice is above the twenty-year mean.

We have heard much of the dangers of global warming due to carbon dioxide. But the potential danger of any potential anthropogenic warming is trivial compared to the risk of entering a new ice age. Public policy decisions should be based on a realistic appraisal that takes both climate scenarios into consideration.

President of Brazil promotes the greatest scientific hoax of all time

President Luiz Inacio Lula da Silva said the floods and drought in two southern states signalled climate change. "Brazil is feeling climate changes that are happening in the world, when there is severe drought in areas that don't have drought, when it rains too much in places where it doesn't rain," President Lula said in his weekly radio address earlier this week.
