In this second part of our IPCC Sixth Assessment report (“AR6”) Working Group III coverage, we welcome back our friend and AR6 contributing author Glen Peters of the CICERO Center for International Climate Research. Longtime listeners will remember Glen from his explanation of the ‘carbon budget’ in Episode #57, and on the various scenarios for global warming, what they mean, and the current trajectory for climate change in Episode #112.

Glen was a lead author of AR6 Chapter 3, titled “Mitigation pathways compatible with long-term goals,” so in this episode, we discuss the latest figures for the remaining carbon budget; explore the probabilities for limiting warming to 1.5 and 2°C, and we consider the changing views on the role of direct carbon dioxide removal (CDR) and carbon capture and sequestration (CCS) as parts of the climate toolkit. Glen also gives us a very helpful explanation of some of the new terms and metrics used in AR6, such as the Illustrative Mitigation Pathways (IMPs), the warming Classification levels (C1-C8) and the other policy scenarios.

This is super-geeky but essential-to-understand stuff for anyone working on climate policy!

Guest:

 Dr. Glen Peters has been a Senior Researcher at the CICERO Center for International Climate Research in Oslo, Norway, for nearly ten years. His current research focuses on the causes of recent changes in carbon dioxide emission trends at the global and country level, and how these changes link to future emission pathways consistent with global climate objectives. He is particularly interested in how emission scenarios are created, interpreted, and used, and how this relates to ongoing policy discussions. He has a background in mathematics and physics.
