Denier Down: Lindzen Retires

Climate change skeptic Richard Lindzen, most famous perhaps for arguing that global warming would be naturally offset by the Earth's adaptive infrared iris ( a theory which has been pretty thoroughly discredited over the years) , has officially retired.  Perhaps, and hopefully, he will step away from various odd theories, but who knows he might take this as an opportunity to pursue the right-wing talking-head circuit with renewed vigor. His work passed long ago from the realm of science to propaganda.
