Climate Roulette

In this podcast we use NotebookLM's "Conversation Mode" to dig into the 18 LinkedIn posts included in Issue 18 of the Climate Change on LinkedIn Newsletter, which you can access here:   Newsletter Issue #18   We've produced two versions of the podcast, "Conversation Mode" and "Debate Mode".   We'd love to hear which you find most insightful for future audio Newsletters.

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.   

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.  

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.   

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.    

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.  

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.
