S3E17: Black holes, climate change, & ... Christianity?—w/ Dr. Heino Falcke, astrophysicist
"We humans are just specks of dust on a slightly bigger speck of dust in the immeasurable vastness of space. We can't cause stars toexplode, we don't set the wheels of galaxies spinning, and it is not we who span the vault of heaven above us. But we can marvel at theuniverse and ask questions about it. We can have faith, hope, and love in this world-and this makes us stardust of a very special kind."—Dr. Heino FalckeWe tend to think that science and spirituality are mutually exclusive. But for Dr. Heino Falcke, a belief in something bigger complements his understanding of the universe.Dr. Falcke is a Professor of Astroparticle Physics and Radio Astronomy at Radboud University. He is also the author of Light in the Darkness: Black Holes, the Universe, and Us.On this episode of Reversing Climate Change, Dr. Falcke joins Ross and cohost and Nori advisor David Addison to discuss the origin of carbon molecules and describe what drew him to the study of black holes.Dr. Falcke explains how he captured the first photograph of a black hole through the Event Horizon Telescope project, sharing what he learned from collaborating with 350 other astrophysicists on EHT and how we might apply those learnings to other global challenges like climate change.Listen in to understand why the complex systems of the universe are inherently unpredictable and learn how Dr. Falcke bridges the gap between the scientific and the spiritual world.ResourcesLight in the Darkness: Black Holes, the Universe, and Us by Heino FalckeDr. Falcke on TwitterDr. Falcke on InstagramDr. Falcke on FacebookDr. Falcke’s WebsiteDavid GrinspoonReinhard Genzel‘Viewing the Shadow of the Black Hole at the Galactic Center’ in The Astrophysical JournalPress Conference Introducing the First Image of the Black Hole‘First Image of a Black Hole Gets a Polarizing Update That Sheds Light on Magnetic Fields’ on Space.comPeter Brannen on Reversing Climate Change EP087Event Horizon Telescope ProjectJohannes KeplerSir Isaac NewtonContactContact: A Novel by Carl Sagan

S3E7: Do compliance markets work? If so, how much?—w/ Mike Azlen, CEO of Carbon Cap Management LLP
We have talked at length on previous episodes about the flaws in compliance markets. And the team at Nori obviously believes in voluntary carbon markets, as we’re building one ourselves.But there’s a wide range of quality among voluntary markets, and the space is 1,000 times smaller than the compliance programs in progress around the world.So, have cap-and-trade markets contributed to a meaningful reduction in emissions in spite of their flaws? And are compliance markets the only way to address carbon emissions at scale?Michael Azlen is the Founder and CEO of Cabon Cap Management LLP and Co-Portfolio Manager of the World Carbon Fund. On this episode of Reversing Climate Change, Michael joins Ross and guest cohost Aldyen Donnelly to explain how he got interested in carbon as an asset class and share his take on the benefits of compliance markets.Aldyen offers insight on the two compliance market models, describing the problems associated with programs modeled after the SO2 Allowance Market—and why she prefers the framework of the Montreal Protocol.Listen in to understand how Michael thinks about regulating voluntary carbon markets and why he is optimistic about the global growth in compliance markets despite their imperfections.ResourcesBecome a paid subscriber of Reversing Climate ChangeFollow the Reversing Climate Change podcast on LinkedInCarbon Cap ManagementClimate-Crypto, COP26, and Carbon Accounting Rules on Reversing Climate Change S3EP1Michael’s Paper on Carbon as an Emerging Asset ClassWorld Carbon FundThe US Acid Rain SO2 Allowance MarketThe Montreal ProtocolEU Emissions Trading SystemFit for 55Kyoto ProtocolClean Air Interstate RuleCross-State Air Pollution RuleThe Regional Greenhouse Gas InitiativeCalifornia’s Cap-and-Trade ProgramCalifornia Scoping Plan DocumentsUK Emissions Trading Scheme
