I don't know. My impression is it is mostly political representation that is there. I like to hear from all sides on an issue before making up my mind. The press coverage seems to suggest that the conference is predicated on the need for reducing CO2 emissions. I am certainly not opposed to that because I believe there will be some worthwhile benefits. But I think it is a mistake not to get the science right before you act. I think the science is telling us that cutting CO2 emissions will have practically no effect on climate, but there will be worthwhile reductions in air pollution that will be incidental. I am very much in favor of getting the science right first.
