Is The Earth Warming Faster Than We Thought? | Ep276: Peter Cox
This week on Cleaning Up, Bryony Worthington is joined by Peter Cox, Professor of Climate System Dynamics at the University of Exeter and Director of the Global Systems Institute. A former lead author of the IPCC climate reports, Peter has spent decades studying the complex feedbacks between the climate, carbon cycle and natural world. They delve into some of the biggest questions in climate science today: Is the planet warming faster than we thought? What is the role of forcing versus feedback? How much of the recent change is being driven by external forces, including the decline of reflecti

The Scandal at The Heart of The Energy Transition | Ep275: Jan Rosenow
Around two-thirds of the energy we put into today’s energy system ends up as rejected heat. So are we measuring the energy transition all wrong? Professor Jan Rosenow joins Michael Liebreich to unpack the “primary energy fallacy”: why focusing on the energy going into the system can obscure the useful energy we actually get out. They explore why electrification can dramatically reduce energy demand, and what genuine systems thinking means for efficiency, waste heat and infrastructure. They also examine hydrogen versus electrification, including Jan’s review of more than 60 independent studies

The Race Is On To Control AI | Episode 274: Afonso Salema & Sam Winter-Levy

This week on Cleaning Up, James Cameron, Chair of Cleaning Up’s Editorial Council, takes over as guest host. He speaks with Sam Winter-Levy, Senior Fellow at the Carnegie Endowment for International Peace, and Afonso Salema, CEO of Exus Digital and founder of TerraByte Data Centers, about how compute is becoming a strategic resource. They explore how acces
