The Climatographers

46 episodes

1 month ago

This podcast features short but frequent episodes exploring the ”known unknowns” and ”unknown unknowns” that will ultimately determine the impacts and outcomes of climate change. The risk-based theme of the podcast is the result of the Climatographers’ Dr. Mark C. Trexler’s more than 35 years of working on climate risks for companies, agencies, and the Intergovernmental Panel on Climate Change. Through show notes the podcast will leverage the Climatographers’ climate change knowledge management solutions The Climate Web and Your Climate Change Toolbox. To make it possible for the podcast to keep up with the fast-moving pace of climate news and events, the podcast will combine Mark’s voice with the extraordinary AI voices being generated by Google’s NotebookLM program. Podcast content will always be human-curated and fact-checked.

DOE Sets Out to Rebut the Scientific Consensus

As part of the Administration's efforts to rescind the EPA's 2009 Endangerment Finding relating to carbon dioxide emissions, the Department of Energy has just released a 151 page report attempting to undercut consensus climate science, authored by 5 prominent climate skeptics. This podcast reviews the report's basic findings, how scientists are reacting to the report, and the Climatographers' own interpretation of the report.

Can the EPA Rescind the Endangerment Finding

The Trump administration wants to undo the 2009 Endangerment Finding from the EPA that set the stage for federal efforts to regulate greenhouse gases through fuel efficiency standards and other means. The legal basis for such a step is questionable at best, but with today's Supreme Court it's hard to predict what will happen. This episode provides a good look at the issues involved.

Where the Business Climate Risk Conversation Stood in 2011

The first business climate risk textbook, written for the London School of Economics, was published in 2011. It was co-authored by the Climate Roulette podcast's producer Dr. Mark Trexler. It's main points and conclusions have stood the test of time remarkably well. It represented one of the earliest calls for companies to place more emphasis on their "policy footprint" than their "carbon footprint." It pointed out that the only way to really manage the business risks of climate change would be to mitigate climate change, and that that would require public policies. This extended episode provides an in-depth overview of that 2011 textbook: The Changing Profile of Business Climate Risk.

Making the ICJ Climate Ruling Really Matter

This is our third Climate Roulette episode involving the recent ICJ Climate Ruling. This one specifically explores the challenges the Advisory ruling faces in really changing climate outcomes. We use the metaphor of Climate Chess, also discussed in prior episodes of the podcast, to explore strategies that would make the ICJ ruling more consequential.

Are Global Forests Threatened by Fire?

According to a new paper fires are rapidly growing in importance as a source of so-called "forest disturbance" around the world. This isn't unexpected as climate change increases the length of fire seasons, creates dryer fuels, and creates more weather events conducive to fires. It's too early to say whether a "tipping point" has been reached, and the picture is complicated by how rapidly our ability to directly observe global forests is improving, but it's an element of the climate roulette picture that bears close watching.

Is the Land-Based Carbon Sink Disappearing?

It's well known that the oceans and land-based ecosystems have historically absorbed about 50% of human emissions of CO2, with the other half remaining in the atmosphere. But scientists have worried that this natural uptake of CO2 might not last forever. This new paper suggests that as the world warms, land-based CO2 sinks might already be close to tipping, which would substantially accelerate the accumulation of CO2 in the atmosphere.

Will Adapting to Climate Change be More Successful?

There are lots of reasons we're failing to mitigate climate change at the scale scientists are calling for, and there's a lot of discussion of the need to focus more on adapting to the climate change that will occur. But will adaptation be more successful than mitigation, or do they both face the same kinds of barriers. This episode explores this very interesting and important question.

Climate Extremes and Food Prices

Risk experts have been worried about the implications of climate change for food prices around the world for years. This episode reports on one of the first studies to try and empirically link specific climate events with specific food price spikes. No one study can be definitive, but it's an interesting exploration of not only the observed effect on food prices, but the impact of food prices on geopolitical stability.

Individual Opinions from the ICJ Judges

Part 1 of this episode series focused on the unanimous ruling delivered by the large bench of ICJ judges. This Part 2 focuses on the supplemental opinions that almost all the judges also added to the record, in most cases wishing the court had been willing to go further than it did in specific areas of the ruling. Even though the unanimous ruling itself is only advisory, these supplemental opinions are likely to provide climate advocates with ideas of where to try and take climate change litigation in the future.

The ICJ's Brand New Climate Ruling - Part 1

Climate advocates have been waiting for this ruling from the International Court of Justice for many months, and it largely delivers on what advocates were hoping for! This Part 1 of the podcast focuses on the main ICF ruling, which was unanimous. Part 2 focuses instead on a whole series of supplemental rulings and declarations from the very same judges, in many cases wishing the court had gone further in its decision.

Can We Get to the Critical Minerals we Need

This episode explores Ernest Scheyder's 2024 book "The War Below - Lithium Copper and the Globl Battle to Power Our Lives," which in turn digs into how difficult it would be to try and access critical minerals in the United States given the opposition to new mines that would be inevitable.

The Growing Challenge of Climate Migration

This episode digs into "On the Move - The Overheating Earth and the Uprooting of America." It's part of a larger conversation about the likelihood that a warming world will displace hundreds of millions if not billions of people. The secondary geopolitical and other implications are hard to get our heads around.

Exploring Paul Gilding's "Great Disruption"

Paul Gilding wrote a great book in 2011 where he envisioned that by 2018 we'd hit a societal tipping point that would motivate dramatic efforts to tackle climate change. It may have been the first serious look at the ideas of an "inevitable policy response" and "positive tipping points." The book includes a detailed "1 Degree War Plan" that lays out what would be required to stop global warming in its tracks.

Alex Epstein, Energy Humanism, and the "Big Beautiful Bill"

Alex Epstein is an "energy humanist" who believes that we need to burn more fossil fuels in order to improve the human condition. And he had a big impact in the discussions leading up to the signing of the "Big Beautiful Bill" that radically rolled back efforts to reduce U.S. GHG emissions. This episode explores his views and his influential role.

The Next Frontier in Climate Engineering?

Geoengineering is a hot topic in climate circles. There are all kinds of such proposals in play, but now there is a completely new idea to contend with. Can we stop Antarctic glaciers from sliding into the sea and causing sea level rise? That's the question some scientists are now exploring, and we explore it in this episode of Climate Roulette.

How Sensitive Is Global Temperature to GHG Emissions?

"Climate Sensitivity" is the most important "known unknown" when it comes to climate change. As greenhouse gas concentrations increase in the atmosphere, how will average global temperature respond? Scientists have been discussing this question for decades, but we just don't really know the answer.
