Episode 4: Earth System responses up to net zero and beyond with Deliang Chen
Show notes
In this fourth episode of the nine-part IIASA podcast series, we turn to the conference’s third theme: Earth System Responses up to Net Zero and Beyond with session chair Deliang Chen. Uncertainties in how the Earth System reacts during and after overshoot remain substantial—and they will shape the potential for reversing global warming. What determines the level of peak warming, and how much does this influence the scale and impacts of overshoot? Does the Earth System behave differently once we reach global net negative emissions compared to the path leading up to net zero?
Exploring these questions is crucial for understanding how quickly temperatures might decline, and how much carbon dioxide removal (CDR) could be required. This theme brings together perspectives from whole Earth System studies as well as targeted insights into specific components, such as the carbon cycle. Emerging evidence from the observational record adds further nuance to the debate.
This podcast is for both curious listeners and conference participants who want to gain an overview of the thinking on Earth System responses in a world facing climate overshoot.
