The Worldwatch Institute and Grist have posted a three-part series (part 3 here and here) commemorating the 20-year anniversary of NASA scientist James Hansen’s groundbreaking testimony on global climate change next week. We spoke with the reporter for part 3: “Jim did a great deal to help unmask the Bush administration’s collusion with the global warming disinformation campaign. He’s a bit like a lone wolf. Nobody can tell him what to say or what to do. They made a mistake when they tried to mess with him.”
