Few issues today command our attention more than that of climate change, and few people have been tracking it longer or have spent more of their lives trying to understand and form policy to respond to it than Gus Speth.
An abbreviated list of his environmental posts includes founder of the Natural Resources Defense Council and the World Resources Institute, Environmental Advisor to Presidents Carter and Clinton, Chair of the UN Development Group, and Dean of Yale School of Forestry and Environmental Studies.
His new memoir is Angels by the River.
