Caught in the crossfire between climate deniers and catastrophists, the intelligent layperson is understandably bewildered when faced with the complexity of climate change. How To Think About Climate Change shows that economics provides not just a suitable, but an indispensable perspective to understand the root causes of the climate-change problem: scarcity of resources, externalities and free riding. Riccardo Rebonato argues that there are no silver bullets or easy solutions. However, he shows that the new-generation economics models offer a radically different insight about our best course of action from what most early models recommended – in particular, they suggest that fast and large-scale climate action can now be justified as the most cost-effective strategy without requiring the 'infinite altruism' of earlier models. Given the conceptual tools provided in this book, readers can decide whether they agree with these conclusions – and, if they do, what the most effective courses of action are.

‘Riccardo Rebonato has done it again! Notwithstanding its humble title, his latest book is filled with rich insights from the interface of economics and climate science, for both the concerned citizen and the seasoned expert. It's all there: the economics and the climate science, the facts and the models, the costs and the benefits. Rebonato offers uniquely-informed economic insights on mitigation, adaptation, new technologies, and ​open questions.’

‘Anthropogenic climate change is a market failure, and its solution will require close collaboration between physicists and economists. Professor Rebonato’s unique background as a trained physicist and a world-renowned finance expert shines through in this wonderful book, making it one of the most authoritative treatments of this subject possible.’

‘Riccardo Rebonato is a well-known practitioner, author, and economist. He is celebrated for his insightful contributions to financial engineering, economic modeling, and climate change discourse, habitually offering fresh perspectives on complex global challenges. How To Think About Climate Change empowers readers to confront the climate crisis with renewed understanding and purpose. Rebonato's book is essential for anyone seeking an enlightened and actionable perspective on one of the most pressing issues of our time.’
