Lord Nicholas Stern is held in high regards in climate circles, because he literally wrote the book on the economics of climate change. The Stern Review on the Economics of Climate Change, published in 2006, is the most significant and most influential report out there.
Today, I went to a public lecture from Lord Stern on, you guessed it, the economics of climate change. It’s stirringly persuasive, though comes from a completely different than the Al Gore presentation that I’ve become accustomed to.
[Edit: The next day, Lord Stern came to a workshop breakout that I moderated at the conference I’m currently at.]
