(NECN) - Dr. James Hansen, director of NASA's Goddard Institute of Space Studies, and author Mark Bowen were in Lexington, Mass. on Sunday night to talk about global warming. Hansen has been studying global warming for over three decades, and just over a year ago spoke out against the Bush administration, saying it was trying to silence his warnings about the issue. Bowen has written a book about about Hansen's teachings titled "Censoring Science: Inside the Political Attack on Dr. James Hansen." NECN's Mark Sudol joins us with more.
