Leading scientists from academia, industry and government are now gaining access to information on climate change that’s collected by spy agencies. The data, which includes high resolution images taken from intelligence satellites, is helping researchers better understand changes happening to the earth as a result of global warming, such as melting ice at the poles and expanding deserts. The CIA, led by Director Leon Panetta, is running the collaborative effort that shares classified information with about 60 scientists, and the National Reconnaissance Office, which operates the nation’s fleet of spy satellites, is providing much of the data.
