One of many examples of a G.W. Bush administration statement edited to reduce or (in this case) remove warnings about climate change, and to heighten feelings of uncertainty, beyond the original statements by science advisers and advisory groups. The edits shown are by Philip Cooney, a lawyer-lobbyist who had earlier helped lead oil industry opposition to limits on greenhouse gases, then became chief of staff for the White House Council on Environmental Quality and altered many statements. Two days after his activity was revealed in 2005, he left the administration and was hired by oil industry giant ExxonMobil.

The story was broken by Andrew Revkin, New York Times, June 8, 2005, using information from resigned official Rick S. Piltz.
