Bjørn Lomborg was one of this site's first targets. We still get emails about that series. Suffice to say, not much love is lost between he and Grist.
Still, Lomborg is widely influential, and the project behind his Copenhagen Consensus makes sense: figure out the most effective way to spend money to save lives and improve the world. I disagree with his conclusions and think the methodology has deep flaws, but the idea behind it is laudable.
Lomborg's got a new book out: a collection of essays called How to Spend 50 Billion, in which economists present their Copenhagen conclusions. What follows is an excerpt, with an introduction by Lomborg and parts of an essay by William R. Cline comparing various global warming mitigation strategies. Give it some thought and share your impressions in comments.
