According to President Bush's former press secretary, the former president's refusal to sign the Kyoto climate change deal in 2005 set the stage for current climate change negotiations in Copenhagen.

"Because [Bush] declined to go forward with Kyoto, which is ultimately the right thing to do because the major economies like China and India weren't at the table, he worked to get them at the table and now this meeting is the next logical step in that process," Perino told Fox News' Chris Wallace Sunday.
