Poor Richard Tol. He has been invited (nominated by the Oirish Gummit, apparently) to be a convening author, though only for WG II.
But all he can do is whinge that “Political interference in the IPCC continues” because they won’t provide him a blank cheque for his travel costs. Diddums. I’m sure you can all see the interference inherent in the system. Still, at least he is better than RP Jr, who refuses (for some reason he does not trouble to explain) to take part. So he can be outside the tent pissing in, would be my guess. Or he might be jealous of Tol getting *convening* lead author, perhaps [update: scuttlebutt confirms this interpretation].
OTOH, this one on fossil fuel subsidies is worth reading.
