How do you feel about scientists 'debating' global warming with skeptics?

"Some of us have even been cajoled into accepting [debate challenges]...Gavin did an infamous one against Crichton and company. People are always demanding that Al Gore debate somebody or other...It is not that scientists don't debate, dispute, disagree about matters related to climate. All those things happen, but not on the subjects that skeptics like Inhofe or Fred Singer or Dennis Avery would like to debate (like whether global warming is mainly caused by CO2 or solar variability, or whether the IPCC warming forecasts represent a credible threat.). Those sorts of things are indeed considered settled science by serious climate scientists."

What do you think of Pierrehumbert's take on debates?
