Reader Jan sends notice on the approval of the IPCC WGAR5 summary for policymakers pdf. (link fixed)
Lifted from his e-mail, he muses:
As for all IPCC reports, this one is a little thick, but can be parsed by the economically inclined.
It is, on the one hand, lousy if unsurprising news. On the other hand, it spells out options, and makes the first coherent, global attempt to price what various options might cost. That’s a very positive step.
It is probably most heartening that the signatory governments of the world, members of the IPCC, had to review this language before it could be released, and might have vetoed statements they did not approve of. This included all the major petro-nations of the world.
