I’m a climate economist at Columbia Business School and author of six books, including Climate Shock and Geoengineering: the Gamble. My research, teaching, writing, and speaking focus on climate risks and solutions. I write a monthly syndicated column, semi-regular FT case studies, run Columbia's Climate Knowledge Initiative, and generally try to keep busy and useful.
