How much of global warming is due to human activity is far from clear. And if the current, modest, gradual warming continues, there will be winners and losers, and plenty of time to adjust. Winners will include, for instance, those pursuing agriculture in northern regions, and shippers seeking a feasible ‘Northwest Passage.’
Economic forecasting is highly inaccurate beyond a few months out, for most variables, So who can honestly claim to know that the long-term losses of the losers will be larger than the long-term gains of the winners?
And if I am right, then what Michael Griffin said below, makes sense, and did not deserve the contempt and vitriol he received from the global warming environmentalists.
(p. A21) “I have no doubt that global — that a trend of global warming exists,” the administrator of NASA, Michael Griffin, said in a taped interview that was broadcast Thursday on National Public Radio. “I am not sure that it is fair to say that is a problem we must wrestle with.”
“I would ask which human beings, where and when, are to be accorded the privilege of deciding that this particular climate that we have right here today, right now, is the best climate for all other human beings,” he said. “I think that’s a rather arrogant position for people to take.”

Jerry Mahlman, a scientist at the National Center for Atmospheric Research, said Mr. Griffin’s remarks showed he was either “totally clueless” or “a deep antiglobal warming ideologue.”
James Hansen, a top NASA climate scientist and lead author of the research paper, said the comments showed “arrogance and ignorance” because millions of people will probably be harmed by global warming.
