Now the island is described as an environmental catasptrophe, requiring an expensive rescue.  An untested model yielded an 'unintended consequences' disaster.Modeling the ecosystem of an isolated island is child's play compared to modeling the global climate. And the scope of the catastrophe possible when intervening to wreck the world economy based on questionable, unverified models...(Read Full Post)
