Economics (again) 

Per talk above, I tried to shorten the dubious but newsworthy economic stuff by replacing the Stern material by the more recent IPCC 2007 statements. The Stern stuff has been re-added by , despite that it needlessly makes this section longer than it should be and that it is now quite outdated (Stern cost is 1% of GDP, IPCC 2007 is 0,1% - both per annum). Considering these numbers, Stern is no longer even good for the news, and if it stays, it should not be mentioned prior to the more recent numbers should it?
