Problems 

I took some stuff out .

 he wasn't a lead author for IPCC '90. That appears to be a mangled version of He was the principal author of the Resource Use and Management Subgroup report in the IPCC’s First Assessment.  Quite what that is I don't know, but its different.
 the other stuff was a copyvio from the same source.

Also, I'm not convinced that http://www.world-economics-journal.com/Contents/AuthorDetails.aspx?AID=418 is a RS for a biog; it looks very much like author-supplied material
