“There has been a net warming of the earth over the last century and a half, and our greenhouse gas emissions are contributing at some level. Both of these statements are almost certainly true. What of it? Recently many people have said that the earth is facing a crisis requiring urgent action. This statement has nothing to do with science. There is no compelling evidence that the warming trend we’ve seen will amount to anything close to catastrophe… Looking back on the earth’s climate history, it’s apparent that there’s no such thing as an optimal temperature — a climate at which everything is just right. The current alarm rests on the false assumption not only that we live in a perfect world, temperaturewise, but also that our warming forecasts for the year 2040 are somehow more reliable than the weatherman’s forecast for next week” — MIT meteorology professor Richard S. Lindzen, writing in Newsweek.
