James Hansen is at it again.
Hansen, who runs NASA’s Goddard Institute for Space Studies in Manhattan, is usually billed as a climate scientist — not to mention the godfather of the current global warming concern.
But Hansen now spends as much time marching in demonstrations and petitioning governments for action on climate change as he does doing research. He engages in plenty of unscientific rhetoric, such as calling trains taking coal to electrical generating stations “death trains” because of the carbon dioxide given off by burning coal to generate power. He has even testified in court in Britain on behalf of environmentalist vandals who sought to infiltrate a power plant and cause it to shut down.
Hansen and two other authors published a study last week that claims extreme weather events, especially droughts, are increasing in frequency and intensity and that it is “99% certain” that the cause is man-made global warming.
Nice conclusion — if your intent is to scare the public and politicians into action. But even many scientists not known as global-warming skeptics have shaken their heads in disbelief at the sloppiness of Hansen’s latest work.
