Positive Tipping Points: How to Fix the Climate Crisis
October 23, 2025
Hear from Prof. Tim Lenton OBE, as we explore the potential of positive tipping points in accelerating the transition to a net-zero economy.
What happens when the conversation about climate change shifts from avoiding disaster to unlocking positive change? Suddenly, it’s not just about risk - it’s about momentum. Because while some systems may be close to dangerous tipping points, others – like clean energy, electric transport, and sustainable food – are tipping in the right direction.
That’s why in this episode, we explore how to accelerate those positive shifts, including:
· How smart policies can trigger widespread, self-reinforcing change across economies and societies;
· Why leveraging social norms and human behavior is just as critical as investing in technology;
· And what it takes to create the tipping points that move us toward a stable climate, not away from one.

Speaker’s Bio
Prof. Tim Lenton OBE, Founding Director, Global Systems Institute, and Chair in Climate Change and Earth System Science, University of Exeter
Tim is the founding Director of the Global Systems Institute at the University of Exeter and Chair in Climate Change and Earth System Science. He has more than 25 years research experience, focused on modelling of the biosphere, climate, biogeochemical cycles, and associated tipping points. Tim is renowned for his work identifying climate tipping points, which informed the setting of the 1.5C climate target, associated net zero targets, and nationally determined contributions.
Tim works with policymakers and businesses helping them assess the risks of climate change and nature loss and highlighting the opportunities for ‘positive tipping points’ that can accelerate change towards net zero. In 2023, Professor Lenton led a team of more than 200 people from over 90 organisations in 26 countries to produce an authoritative assessment of the risks and opportunities of both negative and positive tipping points in the Earth system and society. The ‘Global Tipping Points Report’ produced in partnership with Bezos Earth Fund was published at COP28.
