I find the response to this sort of paper to usually be an interesting 
litmus test for the degree to which people have projected their own 
politico-socio-economic wishes onto the canvas of climate change.

There are those for who this will obviously negate the need to think 
further about fossil fuel consumption, as it basically solves the 
problem (if there ever was a problem). There are others who will argue 
that this is no good, it is bound to have other effects, and what we 
really need to do is reduce consumption of fossil fuels (and probably 
everything else).

Probably the truth really is somewhere in between (by which choice of 
words I am trying to avoid the trap of indicating that the truth is 
likely to be half way between the worst extremes on both sides, ina 
"false balance" stylee).
