BBC Radio: A Geochemical History of Life on Earth
Justin Rowlatt discovers how phosphorus may have held evolution back for a billion years. How plants first colonised the land - precipitating an ice age in the process. And why volcanoes have both rescued and almost wiped out life on the planet, thanks to the carbon dioxide they emit. Professor Tim Lenton explains why he thinks lowly lichen may have turned the Earth into a snowball. Listen here
Biden Administration climate finance report
The White House released a new report, A Roadmap to Build a Climate-Resilient Economy, ahead of COP26. The report recognises that climate change poses a systemic risk to the US economy and that decisive action must be taken to mitigate its impacts, setting out steps for action. Tipping points research by GSI Director, Professor Tim Lenton was cited in the report. Read full report here
Amazônia exhibition at the Science Museum
The exhibition Amazônia, at the Science Museum in London running from October 2021- March 2022, celebrates the indiginous peoples and varied landscapes of the Brazilian rainforest through the stunning images of the photographer, Sebastião Salgado. GSI Director Professor Tim Lenton was part of the Scientific Advisory board for the exhibition and contributed to an accompanying short film and blog. More information.

GSI Contribution: Director Tim Lenton
A stability analysis of the ice sheet covering a large area of Greenland suggests that the ice melting may be approaching a point of no return.
“The results are sobering, but the way they have managed to [obtain them] is impressive,” says University of Exeter, UK, climate scientist Tim Lenton. While the ice sheet is a sluggish system that changes on very slow timescales, the fact that the researchers could extract signatures of the slowed-down fluctuations from observational data is “a real pleasant surprise.” Lenton says that results like those obtained by Boers and Rypdal support earlier calls for developing tools for anticipating climate change impacts (see, for instance, the 2013 National Academy of Sciences report). “With a relatively modest investment we could develop an early warning signal for a range of climate tipping points,” Lenton says.

Big Biology Podcast
Survival of the Systems: The power of persistence
Big Biology is a podcast that tells the stories of scientists tackling some of the biggest unanswered questions in biology.
On this episode of Big Biology, we talk to Tim Lenton, Director of the Global Systems Institute. In his 2021 Trends in Ecology & Evolution paper “Survival of the Systems,” Tim outlined his idea that large, complex systems--such as grasslands, coral reefs, and even human economies--are subject to a kind of natural selection based on their ability to persist. Tim argues that systems better able to extract and recycle resources will spread across landscapes and outcompete other such systems.

Nobel Prize Summit 2021 Webinar: Tipping Points for Sustainability Transitions
Ecosystems are being destabilized by climate change and are at risk of reaching irreversible tipping points. Which way will things tip? How to manage tipping points as opportunities? Tipping points experts discuss these and other urgent questions in this Webinar (30 March 2021). With Hans Joachim Schellnhuber (PIK), Tim Lenton (Uni. Exeter), Cameron Hepburn (Uni. Oxford), Ilona M. Otto (Uni. Graz), Jonathan Donges (PIK), Manjana Milkoreit (Uni Oslo), Peter Bakker (WBCSD). Moderator: Oliver Morton (the Economist).
Podcast: The Sustainability Agenda
The Sustainability Agenda is a weekly podcast exploring today’s biggest sustainability questions. Leading sustainability thinkers offer their views on the biggest sustainability challenges, share the latest thinking, identify what’s working --and what needs to change -- and think about the future of sustainability.
In this interview, Professor Tim Lenton discusses his work with Bruno Latour, exploring how humans could add some level of self-awareness to Earth's self-regulation.

GARP’s Climate Risk Podcast
The systemic and existential nature of the risks arising from climate change requires us to engage with the problem strategically at a high level. But how can we do this when the problem is so vast and complex?
During this episode, you will hear from Tim Lenton, a leading academic in the field of earth system science and co-author of the seminal and award-winning paper on climatic tipping points and the non-linearity of climate change.
