The global environment over the next 30 years

I've been reading the United Nations Environment Programme's Global Environment Outlook 3 which was released last week. It looks at the state of our world right now and what it might be over the next thirty years (the summary is a 1.6MB PDF). As well as a lot of current information, it features a set of four detailed global scenarios over 80 pages (the scenario chapter is a 2.5MB PDF). Three scenarios could be described as a continuum from a world where profit comes first to where the environment comes first (the latter unfortunately sounding the least likely). The fourth scenario focuses on the possibility that wealthy parts of the globe will attempt to insulate themselves from the poorer, more volatile societies. While the descriptions avoid almost any mention of specific countries they are very detailed and include many pages of charts and maps showing the implications of each scenario on different regions. The scenarios mention that some future events have the "War on Terrorism" as their cause and part of me wonders whether it's a good idea to base such long-term thoughts on something still so new. But, as the report mentions, most of the decisions have already been made that will affect our environment over the next thirty years and we need to look beyond that.
