Marco Visscher serves up a thoughtful piece about climate change adaptation. I didn’t know that my book is reviled by climate activists. I am a “climate activist”. I’m working with the California Air Resources Board to help implement AB32 to be cost effective. I support gas taxes of $5 a gallon. I’m on record as supporting higher electricity prices and water prices. Where Joe Romm and I disagree (and I respect his passion but not his economic logic), focuses on my confidence that free market capitalism continues to reinvent its game. We are not passive victims here. We will have an ever growing set of possible adaptation strategies due to innovation. The “big question” here is the role that human capital can play in protecting us against “Mother Nature” and the role that free market capitalism plays in directing our best minds to work on these problems.
