Mostly on the blogs we give our attention to the corruption of climate science by the politics of climate change. However, beyond the physics of climate and its physical impact, recently there has been a small revival of interest in the economic damages climate change is expected to cause, and how the costings of these damages is weighed against the costings of various mitigation efforts.
Such cost/benefit analysis should be the ultimate instruction to policy action, yet it introduces whole new layers of uncertainty that render such assessments even less tolerable to sceptics. This analysis is no more tolerable, or tolerated, even where the results present sober and moderate, even when they all but call off the alarm. This hit home hard with the recent treatment of work by a reader and commenter on this site: Richard Tol might be one of the most vocal and scathing expert critics of the Stern Review, but he still had to weather the onslaught against his own sobering damage assessment when it was posted on WUWT.
Tol’s willingness to engage across the borders of this fractious debate is admirable, and some BH readers may know of his previous work with Bjørn Lomborg on the Copenhagen Consensus. But many readers may not know that Tol’s very academic career was baptised in an earlier fiery controversy. While still a PhD candidate in his early 20s, Tol was swept up in the first public controversy ever to hit the IPCC.
The tale of this ‘price of life controversy’, like the tale of Tol’s career, is not easily reduced to a simple yarn of black and white, sceptic/alarmist, good and evil. Its significance presents in more subtle ways, and sometime in direct contradiction to the motives of the various actors. Thus, this story takes a bit of work to get into. However, it may reward those readers curious about the early history of the IPCC during the time when it was still engaging with the gathering political forces but not yet overwhelmed by them. The following is a short summary, while more detail can be found here.
