global warming is not so much a scientific theory subject to empirical falsification as it is a political ideology that must be fiercely defended in defiance of every fact to the contrary. In the past few years we have been told that not only hot weather but cold weather is caused by global warming. The blizzards that struck the east coast of the US in 2010 were attributed to global warming. Every weather event–hot, cold, wet or dry–is said to be caused by global warming. The theory that explains everything explains nothing.
But remember don’t let anyone tell you that a Snakeoil salesman is a lying, cheating *******.
