Well, this is surprising news. The Guardian is reporting that the skeptical environmentalist, Bjørn Lomborg, has a new book coming out called Smart Solutions to Climate Change in which he declares global warming to be “undoubtedly one of the chief concerns facing the world today” and he will be calling for tens of billions of dollars to be invested in climate change mitigation.

And, he will advocate for financing those tens of billions with a carbon tax!

This is a complete turn around from the position he argued in last year’s Munk Debate when he and climate-science skeptic Nigel Lawson squared off against George Monbiot and Elizabeth May.

Strange that he would have argued that climate change wasn’t worthy of a $100 billion investment back in December of 2009 and then make an about face this summer. Presumably he was researching the new book back when the Munk was taking place, if not actually writing it.

Have to say, I’m damn curious as to how he’ll justify all this. And I’m more than a little skeptical of Lomborg’s apparent change of face. Guess we’ll have to see how this shakes out.
