An email: Mr. Murray, You wrote: “First, as Sunstein acknowledges, the effect of Kyoto, ambitious as it is, would – on its supporters own admission and accepting all their contentions – be to reduce additional warming by a measly 0.07 deg C by 2050.” Climate skeptics often quote these numbers. They come from climate modeling. Does that mean you now accept the climate models as accurate? As I said “accepting all their contentions.” If the models overestimate warming, as I’m sure they do, then the effect will be that much less.Even on the overblown assumptions of modelers, the protocol is virtually useless at doing what it is intended to do – reduce warming. That pretty much makes our case for us as well.
