This coming Monday, June 23, 2008, will mark the twentieth anniversary of Jim Hansen’s course-altering testimony to the Senate Committee on Energy and Natural Resources. (I give some of the back story to that moment in Chapter 9 of Censoring Science.) The Worldwatch Institute will duly recognize Jim’s pioneering contributions with a luncheon at Washington’s National Press Club Ballroom that day, and he will also be testifying to Congressman Edward Markey’s Committee on Energy Independence and Global Warming. (In keeping with his usual breakneck pace, Jim happens to be in Germany at the moment, meeting with the Minister of the Environment — another front in his effort to convince government leaders around the globe to do what they can to stop the building of old-fashioned coal-fired power plants.) I highly recommend the interview with Jim that appears on the Worldwatch Web site, as a good snapshot of his current thinking.
