[Episode #216] – COP28 and the Outlook for Oil

Following from the December COP28 climate summit, we find ourselves at a pivotal juncture with the world’s governments clearer than ever about “transitioning away from fossil fuels.” Now, what is next for the oil sector and for all of us—the consumers of oil? Is COP’s sweeping announcement setting a ceiling for the global ambition on climate, or merely a floor?

As oil is phased out sector-by-sector, how can the electrification of vehicles handle demand for road transport? And what about the sectors where substitutes are still a work in progress, like petrochemicals, aviation and shipping? Is it really feasible to phase out oil completely, as we discussed with the IEA in the previous episode?

In this episode, we explore these questions with Anand Gopal, the Executive Director of Policy Research at Energy Innovation, an energy transition think tank based in San Francisco. We review the findings from several of Energy Innovation’s recent reports, we discuss the outlook for oil demand, and we get Anand’s first-person observations from this year’s COP.

[Episode #214] – Countering Climate Doomerism

Renowned climate scientist Dr. Michael E. Mann joins us to discuss his new book,
Our Fragile Moment: How Lessons from Earth's Past Can Help Us Survive the Climate Crisis,
and to answer some of the hottest questions in climate science discussions today:

  • Are we doomed?
  • Is the world facing polar ice breakdown if we reach the same CO2 concentrations that existed in the geological past when the planet was free of ice?
  • Is there evidence of “tipping points” in the climate system that will activate “feedback loops” of runaway warming?
  • Will the planet keep warming after our carbon emissions go to zero?
  • Was the Paris target breached when the world exceed 1.5°C of warming for some months of 2023?
  • Are climate scientists using models that underestimate future warming?
  • Is there a chance of limiting warming to only 1.5° or 2°C?

[Episode #173] – IPCC AR6 Part 2

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!

[Episode #57] – Climate Science Part 7 – Carbon Budget

In this seventh episode of our mini-series on climate change, we explore what carbon budgets really mean, and what they indicate about the pathways that might allow us to keep global warming below two degrees C.

Amid all the unavoidable uncertainty in modeling warming and the effects of our actions, what do we really know about how much warming we might see in the future? If it turned out that our carbon budget is larger than we used to think it was, would that change our policy direction? And which policy paths should we advocate?

Our guest in this episode, Dr. Glen Peters, is a veteran researcher on climate change whose 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. And after listening to this nearly two-hour conversation, as well as our previous six episodes on climate science, you will have a much better idea of how much warming we may yet expect!
