Leslie Palti-Guzman exchanges with Dr. Kelly Sims Gallagher, a Tufts University Fletcher School professor and former US climate policymaker, on her new book Titans of Climate. They chat about the reasons that motivated her and her co-author to write the book and the process of writing it. Kelly tells us about China's post-Paris agreement climate actions and China's progress on being a responsible stakeholder. They talk about energy investments within China's Belt and Road initiative and Beijing's ambition to make it greener, as well as US-led Indo-Pacific strategy. In terms of personal trajectory, Kelly explains how it is more challenging for a woman to become a professor with tenure, and how she embraced the opportunity to work for the government--despite feeling guilty for her family at first.
