[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 #211] – Doomers vs. Transitionistas

Full Episode

Should our response to global warming focus on technologies that reduce emissions, or on embracing simpler lifestyles? Why do some believe that deploying more renewables and accelerating the energy transition is essential, while others advocate for ‘degrowth’ instead, and claim that switching to renewables is counterproductive?

Today’s conversation explores a recent paper by lifecycle assessment researcher Marco Raugei of Oxford Brookes University, in which he describes an ongoing debate between “systemic pessimists” who focus on humanity’s demands for resources and dismiss renewable technologies, and “technological optimists” who focus on the technologies of the energy transition but do not address other planetary boundaries. We describe these two tribes and their beliefs, identify their points of disagreement, and try to suggest a way forward.

We’ll also discuss another recent paper Marco co-authored exploring whether there are important material limits to the energy transition. And to wrap it up, Chris offers his longest monologue yet, in which he draws a distinction between “techno-optimists” and energy transition advocates, and suggests some ways that we might advance the debate beyond its current unhelpful framing.

Ultimately, we hope this episode will persuade some “systemic pessimists” to consider shifting their narrative from doom and to refocus on actively solving problems, including the problem of global warming.

[Episode #207] – 8th Anniversary Show

For the Energy Transition Show’s eighth anniversary, we welcome back energy researcher Jonathan Koomey, a veteran guest who shares invaluable insights with us in our annual reviews.

We kick off the episode by analyzing the impact of the global response to Russia’s invasion of Ukraine on the energy transition.

Then we revisit four big energy transition themes:

  1. Command Capitalism: Exploring the growing trend of government intervention in energy markets.
  2. Climate Change Narratives: Challenging the propensity for doom mongering about climate and the energy transition, and exploring why that’s not only unhelpful but also myopic.
  3. Systemic Challenges: Reviewing how our many systems have been rigged in favor of fossil fuels, and discussing strategies to un-rig them.
  4. The Mid-Transition: Navigating the demands of the transitional phase as we shift from old systems to new ones.

Prepare yourself for another smörgåsbord of energy transition goodness! So, strap on a napkin and join us for a journey through the pivotal moments and themes of the past year!

[Episode #203] – The Case for Climate Optimism

Why does so much media coverage of climate change emphasize the worst-case scenarios and the slow speed of the energy transition? Why don't more stories highlight how the energy transition is working and accelerating, reducing expected increases in carbon emissions and rendering the worst-case warming scenarios increasingly unlikely?

These are important questions, because reporting about the climate and the energy transition can be a self-fulfilling prophecy. If the media constantly asserts that climate change is unstoppable and that we’re doomed, people will feel discouraged and give up during a critical time in which we must make progress. Whereas by showing people how they can be part of the solution, they will do what they can and support leaders committed to addressing the problem.

It’s also important that we understand what’s real and likely, and what isn’t. An unfortunate number of stories about climate change have emphasized vague “tipping points” and “feedback loops” that might accelerate warming in the future. But those are unquantified and undefined terms referring to highly uncertain possibilities. Meanwhile, highly probable outcomes that would result from existing climate policies are barely mentioned.

So why is there so much media focus on the worst-case scenarios? A shred of uncertainty isn't a sufficient reason to emphasize the worst case above all else. Wouldn't it make more sense to focus on the likely outcomes of our existing policies?

In this episode, we're joined by a climate researcher and data analyst who finds reason for optimism on climate change. Hannah Ritchie is a Senior Researcher in the Programme for Global Development at the University of Oxford. She is also Deputy Editor and Lead Researcher at the online publication Our World in Data, which brings together the latest data and research on the world's largest problems and makes it accessible for a general audience. Her forthcoming book, Not the End of the World, will be published in January 2024.

In today’s conversation, Hannah explains what converted her from a climate pessimist to an optimist, and shares her insights into why stories of climate doom seem to be more popular. We explore a number of her data analyses that support her optimistic outlook. And we discuss why it’s important to give people hope that we can address the climate challenge successfully—not by merely adopting a pollyannish attitude, but by really looking at the facts, and understanding the progress that we’re actually making.

[Episode #201] – India Update Part 2

This is part two of our interview with Mohua Mukherjee, a Senior Research Fellow at the Oxford Institute for Energy Studies. Previously, she was a development economist and project manager with the World Bank, working in over 40 countries.

In this second part, we dive into India’s use of oil and natural gas, and why it has continued to purchase these fuels from Russia, even as the West has implemented trade restrictions. We go on to explore India’s unique approach to transitioning mobility to vehicles that run on electricity and CNG. We highlight India's strategy for developing domestic industries in battery manufacturing, solar energy, hydrogen electrolyzers, and other clean technologies. We also take a closer look at India's astonishing progress in expanding electricity access to its vast population. We examine the challenges faced by electricity distribution utilities in the country, and their efforts to enhance efficiency. Finally, we address India's progress on its climate initiatives and the importance of ensuring a "just transition" as the nation reduces its reliance on coal-fired power.

Be sure to check out part one of this interview in Episode #199 for a review of India’s overall energy mix, including a close look at its use of coal, solar, and wind.

[Episode #196] – Unglamorous Solutions

Most energy transition reporting narrowly focuses on technology stories. When journalists do occasionally write about energy transition policy and politics, they tend to limit the framing to a particular type of energy technology, such as drilling for oil or putting up a new wind farm.

What if this technological tunnel vision is causing us to overlook the most important aspects of the energy transition? If the most transformative and enduring aspects of transition end up being policy and investment, especially at the local level, these topics rarely get the discussion they deserve. Instead of focusing on flashy technologies like hydrogen and nuclear power, should we also give equal attention to unglamorous solutions like insulation and wider sidewalks? What if the things we need most have no natural champions in industry or political leadership? If so, who will advocate for them?

Our guest in this episode is a researcher who has thought deeply about rebalancing the energy transition conversation. Dr. Marie Claire Brisbois of the University of Sussex draws from her work on power, politics and influence to suggest important changes that we need to make to our institutions of governance and our investment strategies to realize the energy transition’s full potential. It’s a thoughtful, out-of-the-box discussion that will give you much to think about!

[Episode #195] – Permafrost and Climate ‘Tipping Points’

Is the Arctic permafrost in a warming feedback loop that will unleash a methane bomb, pushing the planet past a tipping point and into inevitable climate doom?

Not precisely.

But the warming permafrost does release greenhouse gases, and they do matter. Understanding the Arctic permafrost's role in the global climate cycle is important. And there absolutely is alarming evidence of climate change in the Arctic, to which we must pay attention.

In this episode, permafrost researcher Dr. Gustaf Hugelius of Stockholm University explains what the best scientific evidence says about the thawing of Arctic permafrost and its significance to the climate. We also debunk some of the hyperbolic claims that have been made about it. You’ll learn why, although there are climate feedback loops acting in the Arctic, they are much more predictable and modest in effect than they have been made out to be. You’ll also learn that there are no well-defined “tipping points,” nor is there likely to be a ’methane bomb’ emerging from the permafrost.

So if you’ve been worrying that a tipping point emanating from the Arctic is going to render the whole project of climate action futile, you need to listen to this episode. It’s not so.

[Episode #137] – Energy and Climate in the Biden Administration

What will the Biden-Harris administration mean for America’s energy transition, its relationship with the rest of the world, and for global action on climate? Beyond everybody’s policy wish lists, what’s actually likely to happen, and what do this administration’s top priorities need to be to put the U.S. back on track with climate action?

In this episode, we look at the realpolitik of the current situation, and weigh up the challenges that face us in rebuilding America, as well as what it will take to restore our relationship with the rest of the world and show leadership on climate and energy transition once again. And we consider what the staffing of the new administration can tell us about what kind of character it will have, and what the Cabinet’s policy priorities are likely to be.

In this final episode of 2020, we turn the page and look forward to putting America back on track, and getting back to some semblance of normal life again.

[Episode #117] – Climate Science Part 12b – Improving Climate Modeling

Are the climate change scenarios produced by the Intergovernmental Panel on Climate Change (IPCC) accurately representing our likely futures, or are they rooted in outdated data that doesn’t represent the progress we’re already making on energy transition? Is the world on a “business as usual” path to climate doom in a world that’s 5°C warmer, or are we actually within reach of limiting warming to 2°C by the end of this century?

In this episode, we ask two experts to debate these questions in the very first extended three-way conversation on this podcast. Representing the energy analyst’s critique of the IPCC models is Bloomberg New Energy Finance founder Michael Liebreich. And representing the IPCC modeling work is Dr. Nico Bauer, an integrated assessment modeler with the Potsdam Institute who has helped develop the Shared Socioeconomic Pathways used in the IPCC framework.

This episode is part two of that three-hour conversation. Part one was featured in Episode #116. Together, those two episodes make Part 12 of our mini-series on climate science.
