Back in the 1990s, the CIA opened an environmental center, swapped satellite imagery with Russia and cleared U.S. scientists to access classified information. But when the Bush administration took power, the center was absorbed by another office and work related to the climate was broadly neglected.In 2007, a report by retired high-ranking military officers called attention to the national security implications of climate change, and the National Intelligence Council followed a year later with an assessment on the topic. But some Republicans attacked it as a diversion of resources.And when CIA Director Leon Panetta stood up the climate change center in 2009, conservative lawmakers attempted to block its funding."The CIA's resources should be focused on monitoring terrorists in caves, not polar bears on icebergs," Sen. John Barrasso, R-Wyo., said at the time.
