In an interview with the BBC, Professor John Marburger, Bush’s chief science adviser, said it was an “unequivocal” fact that climate change is man-made and that greenhouse gases emitted by human activity are to blame.
I think there is widespread agreement on certain basics, and one of the most important is that we are producing far more CO2 from fossil fuels than we ought to be. And it’s going to lead to trouble unless we can begin to reduce the amount of fossil fuels we are burning and using in our economies. [...]
The CO2 accumulates in the atmosphere and there’s no end point, it just gets hotter and hotter, and so at some point it becomes unliveable.
Watch the BBC report:
Roger Harrabin, the BBC climate reporter who conducted the interview, noted that “historically, the White House has given a number of different messages on climate change. You hear one message from Dick Cheney saying that there’s a debate we’ll have to carry on.” On the other hand, Marburger says the science is undisputed. So far, Cheney has been winning the battle in setting U.S. policy.
Just this past February, Cheney asserted, “There does not appear to be a consensus” that global warming is “caused by man.” Bush has repeatedly echoed Cheney’s line that there is a “debate” over the science.
Harrabin noted that “there is very little pressure from the public,” causing a kind of “stasis” in the climate change debate. “The headway in the U.S. is very slow,” he said, “and that feeds into the international process where other countries are looking at the U.S. and saying, hey, you’re the big emitter, if you’re not cutting, then how’s that going to impact on our industries.”
