The robust debate between Gavin Schmidt and Judith Curry (here and here) appears to have run its course. It's been a fairly technical discussion and mostly civil. And immensely frustrating, it seems, for both of them. Taking stock of the exchange, Gavin makes this observation:
When smart and informed people see basically the same information but come to different conclusions, I find that interesting since there might be something to be learned.
I think he's right, but what is there to be learned?
