Hansen Unhinged

By Patrick J. Michaels

This week marks 20 years since NASA’s James E. Hansen testified before a joint Congressional hearing that there was a strong “cause and effect” relationship between “current” climate conditions and emissions of carbon dioxide into the atmosphere. Current conditions in 1988 were a big heat wave and drought in the eastern U.S. The public bit. Two days later, 70 percent of the respondents to a CNN poll agreed with the proposition that 1988’s misery was caused by global warming. Yet in fact, no climate scientist can ever blame an individual weather event, like a heat wave or drought, on global warming.

Hansen’s testimony that year included a graph of annual temperatures, with a dramatic spike on the last point, the January-May temperatures. He knew, as does any scientist, that a sample of monthly data will vary much more than year-to-year temperatures, and that monthly data could give a false impression of extremely hot (or cold) conditions, compared to annual temperatures. Hansen has long employed stagecraft for political gain. On June 23, 1988, he delivered his testimony in an unusually toasty hearing room. Why was it so warm? As then-Sen. Tim Wirth (D., Colo.), told ABC’s Frontline: “We went in the night before and opened all the windows, I will admit, right, so that the air conditioning wasn’t working inside the room . . . it was really hot.”

Every climate scientist knows there’s been no - zero - net change in surface temperatures in the last ten years, as shown in the climate history of the United Nations Intergovernmental Panel on Climate Change. None of Hansen’s valid 1988 models predict what’s actually happened. He simply predicted too much warming, especially for the last ten years. Why should we believe what he forecasts for the rest of the 21st century?

Hansen’s 1988 predictions were flatly wrong about the extent of global warming. Yet on the 20th anniversary of his original testimony, Hansen said that people “should be tried for high crimes against humanity and nature” for spreading doubts about the promised global warming holocaust. He named names, too: the CEOs of ExxonMobil and Peabody Energy. Excuse me, Inquisitor Hansen, but what exactly are their crimes against humanity? Being demonstrably wrong about climate science?

Speaking of crimes, what about the Hatch Act, which prohibits federal employees from electioneering? In the hotly contested state of Iowa, on October 26, 2004, Hansen gave a public speech in which he stated that “John Kerry has a far better grasp than President Bush on the important issues that we face.” Kerry lost Iowa by a mere 10,000 votes. Yet Hansen persists. He recently said “the 2008 election is critical for the planet. If Americans turn out to pasture the most brontosaurian congressmen,” maybe we’ll be able to save the planet from the doom he envisions this century. Hansen also wants to tax fossil fuels, making them much more expensive than they are already.  So even though he predicted too much global warming, and his numbers couldn’t explain the ten-year hiatus we’ve experienced, Hansen keeps trying to sway presidential and congressional contests. And he wants to incarcerate any CEO (or scientist, probably) who casts doubt on his vision in public.

The fact of the matter is: Hansen is out of control. NASA employees aren’t supposed to call for tax hikes, endorse candidates, or attack businessmen. Any other federal employee would be warned for doing so, and if he continued, fired (or worse). You have to hand it to him, though: he’s a single, scientific outlier, terrorizing the American people.
