The best, IMHO, alternate explanation for global warming is looking a bit less likely:

“The upshot is that somewhere between 1985 and 1987 all the solar factors that could have affected climate have been going in the wrong direction. If they were really a big factor we would have cooling by now.”

However, as the evidence for man-made global warming continues to accumulate, policymakers and citizens should turn our attention to what should be done about it.

Disclosure: Just in case any H&R readers missed it, I am a former skeptic of man-made global warming. See my mea culpa here.
