"The longer we wait, the more climate change we are committed to in the future." The formulation is eerily similar to Bush's Fram Oil Filter ("Pay me now or pay me later") trope on Social Security. So if it's not the logic he disputes, it must be the science. It would be nice, now that White House news conferences have been rescued from the "Where are they now?" pile, if someone asked the President whose scientific advice he relies upon in rejecting this line of reasoning. Of course, we all suspect that the virtual White House Science Advisor is Dr. James Dobson, but it wouldn't hurt to nail it down.
