Apart from the Judith Curry piece, which I linked to yesterday, there have been a few others interested in what Lewis has to say.
Meanwhile, at Reason magazine, Ronald Bailey gave the story another airing.
My impression is that people are still trying to work out what to say. I think we will hear more in the coming days.
I think a lot of what Nic Lewis says seems reasonable, though I also suspect that some of his choices will have served to underestimate sensitivity somewhat. Don't forget, "the ipcc" does no research to estimate sensitivity, they only summarise the literature which generally lags the latest evidence.
