Professor Michael Obersteiner is one of the scientists who popularised carbon capture - now he's warning that we'll need to run it for 300 years at a cost of up to 10% of global GDP - and the world hasn't even begun to negotiate how to do it. This is what net negative actually means, and why it changes everything about how we think about climate action.
More from Overshoot: Navigating a world beyond 1.5°C
During a sweltering @London Climate Action Week, we recorded a live episode of the Overshoot podcast, exploring the profound challenges to the strategy on climate change of overshooting the 1.5°C target. We discuss what a new climate goal might be, what new technologies might be needed, and what can be done to mitigate catastrophic risks. Moderated by our Executive Director Laurie Laybourn this panel discussion examines how the climate strategy might evolve to meet the new reality. Featured Guests: Baroness Worthington – Crossbench Peer in the UK House of Lords Clara Botto – Director of Outreach at the Alliance for Just Deliberation on Solar Geoengineering Dr. James Dyke – Assistant Director of the Global Systems Institute at the University of Exeter
Sue Owen and Lisa Hopkinson aren't climate scientists or economists. But between them they've uncovered something that should worry anyone with a workplace pension: the assumptions used to model climate risk are, in their words, ridiculous - and the people responsible for billions of pounds don't seem to see it.In this conversation they explain how the Derbyshire Pension Fund's own analysis treats 4°C of warming as a roughly 1% hit to returns, why a chain of advisors, consultants and councillors keeps "batting away" every question, and what they think everyone with a local authority pension should be asking right now.Guests:Sue Owen — Derbyshire Pensioners Action GroupLisa Hopkinson — Divest Derbyshire
On 19 July 2022, Britain hit 40°C for the first time in recorded history. Houses burned to the ground. London ran out of fire engines for the first time since the Blitz. Trains ground to a halt. A major London hospital lost all its patient records. Former BBC journalist David Shukman reveals what actually went wrong that day - and why, four years on, we still aren't ready.
"Wouldn't it be nice if the banks and insurers stopped facilitating the activities that are probably going to have such severe impacts on their industries within the next 30 years?"Actuary Louise Pryor explains how economic models systematically underestimate climate risk, what a sudden repricing of that risk would mean for financial markets, and how the concept of home insurance could become unworkable across large parts of the world.These ideas are discussed in episode 3 of Overshoot, Minsky Moment.Listen to Overshoot podcast wherever you get your podcasts - https://overshootpod.com/
We sit down with investigative climate journalist Amy Westervelt to dissect how the framework of "Net Zero" has been weaponised by the fossil fuel industry to justify continued extraction and emissions. We dive into the empirical and thermodynamic realities of carbon capture and storage (CCS), exploring why scaling this technology faces rigid physical and geological boundaries - such as subterranean pore space constraints and gaseous migration - that limit its theoretical capacity to a fractional 2-3% emission reduction. Westervelt exposes the systemic failure of voluntary carbon markets, tracking how tech giants have funded offset projects in Bolivia and Kenya that resulted in severe environmental and social disruption. The world has already missed 1.5°C. Overshoot explores what comes next.🎧 Listen on Spotify, Apple Podcasts and YouTube🌍 overshootpod.com#climatechange #Overshoot #climatecrisis #Netzero #drilled
