Allow me to add my critique: Astute and well put, elrous0. The issues are actually two fold assuming agreement on the nature and scope of GW. The firsts involves consequence; and, whether GW provides positive effects, net and/or varied by geography, negative effects, same condition boundaries, and who would be affected negatively, positively, and by how much. The second involves actionability, that is, where GW incurs negative effects, whether there are actions humans can implement to avoid or mitigate those effects, and the cost versus benefits of those actions, or even inactions. The off-putting factor to me is that vague theory, as well as solution sets, always seem to revolve around the politics of the camps involved.
