New U.S. Government Report Acknowledges Human-Caused Climate Change

President Bush famously dismissed a 2002 U.S. government report that acknowledged the human causes of climate change as something “put out by the bureaucracy.” Well, it looks like the bureaucracy’s at it again: A new administration report to Congress indicates that human production of heat-trapping greenhouse gases is likely behind the rapid climate change of the past three decades. According to James R. Mahoney, director of government climate research, the report reflects “the best possible scientific information” on climate change. The White House, which has regularly followed the lead of industry groups in emphasizing the uncertainty of climate science, may have difficulty dismissing this report, as it is signed by the secretaries of energy and commerce and Bush’s top science adviser, but you never know.
