Professor Tim Lenton is Chair in Climate Change and Earth System Science at the University of Exeter, where he founded the Global Systems Institute. His research focuses on understanding how life has transformed the Earth system over the past 4 billion years, and how humans are transforming it now. He uses computer models to simulate the climate and biogeochemical cycles. Tim is renowned for his work in identifying climate tipping points, which informed the setting of the 'well below 2°C' climate target. He is passionate about the opportunities for positive tipping points in human activities to accelerate action towards global sustainability.
This is a tour de force: a magnificent exploration of what could be the most important issues of all. I beg you to read it. * George Monbiot, author, journalist, environmental activist * Tipping points are the essence of what is dangerous in climate change, and of what is hopeful and possible in economic change. Tim Lenton realised their importance long before most people, and this is the book to read if you want to understand them better. * Simon Sharpe, author of Five Times Faster: Rethinking the Science, Economics, and Diplomacy of Climate Change * Planetary tipping points threaten. Technological and social tipping points hold the promise. Time to focus! * Christiana Figueres, Former Executive Secretary of the United Nations Climate Change Convention * We could feel despondent and hopeless given the negative tipping points that climate change is crossing. Or instead, we could fight fire with fire, recognizing that there are positive tipping points just as there are negative ones. Consider, for example, the exponential uptake of EVs and the declines in costs for solar PV. So how does some change become nonlinear? That is what this important book shows us. * Sir Andrew Steer, KCMG, PhD, President and CEO, Bezos Earth Fund. * Positive Tipping Points by Tim Lenton is a compelling exploration of Earth's fragile systems, blending cutting-edge science with urgent storytelling. Essential for anyone seeking to understand and navigate our planet's climate challenges. * Tom Rivett-Carnac, Founding Partner, Global Optimism * We live in turbulent times where a big world dictates outcomes on a small planet. Nothing is linear or incremental anymore. Tim Lenton presents the most authoritative effort so far in confronting us humans with this reality. Things can go badly, permanently and fast, things can go well, very fast and at scale. Read this book to calibrate yourself for the stormy times ahead. * Johan Rockström, Professor Earth system science, University of Potsdam, Director of the Potsdam Institute for Climate Impact Research * This is the most enjoyable book ever written on the impending climate catastrophe. Sounds paradoxical, but Lenton provides, in a perfectly readable and even entertaining way, compelling evidence that our familiar world must eventually collapse on the current sociopolitical trajectory. At the same time, he identifies the best of all hopes for rapidly exiting that trajectory. Tipping dynamics, a notion I helped to introduce into climate science several decades ago, is key in both respects: positive nonlinear processes compete with negative ones in the battle for planet Earth. Lenton's wonderful essay may be just the gentle tip we need for winning that fight. * John Schellnhuber, Director General, IIASA, Founder and Shareholder, Bauhaus Erde *
