Pops, you’re making the same error Tom is. Look at what Roger says: “incontrovertible evidence that we exert both warming and cooling effects.” That’s a true statement: for example, go stand in the middle of a big parking lot on a sunny day, and then move over to a lawn Asphalt absorbs much more sunlight than the usual open ground, and we’ve added a lot of asphalt. That’s a warming effect, and it’s incontrovertable, ie, undeniable, and it doesn’t take any models or complicated scienceto observe it.

The thing is, it appears, that you’re confusing “we have incontrovertible affects” with “and that net effect is large and observable.” PIelke consistently says, instead, “and further research is needed to determine how large that net effect is.”
