Climate Chat

In this Climate Chat episode, host Dan Miller Katharine Gage, a climate activist working to get students to rally around the Carbon Fee and Dividend (CFD) carbon pricing policy. Katharine Gage graduated from Bowdoin College with a major in Earth and Oceanographic Science and a minor in Psychology. Her academic work included research in oceanography and biogeochemistry. She has been leading climate advocacy efforts since 8th grade, and now co-leads the Carbon Fee and Dividend Movement and recently gave a TEDx Talk about this effort. Her interest in policymaking also led to two internships in Congressional offices. Next year, Katharine will be pursuing a Masters in Environmental Management.

In this Climate Chat episode, host Dan Miller interviews author and RethinkX's Director of Research, Adam Dorr, about his two books, Brighter, and The Degrowth Delusion. RethinkX is a think tank that focuses on disruptive technologies including renewable energy and precision fermentation. Adam argues renewable energy will dominate future energy supply and that "degrowth" will not provide us with the resources to fight climate change. Adam Dorr is an environmental social scientist, technology theorist, and author. As Director of Research at RethinkX, he leads analysis and forecasting of technology-driven disruptions in energy, transportation, food, and labor. His work argues that the converging disruptions of the 21st century will not only solve our most pressing environmental challenges but also open the door to unprecedented human flourishing. Adam's work makes a data-driven case for optimism about our shared future.

In this Climate Chat episode, host Dan Miller interview Devonian Systems co-founder and CEO Alan Ransil about their approach to producing biochar. Biochar is produced when biomass is burned without the presence of oxygen, a process know as pyrolysis. Wood treated this way is also known as charcoal. Biochar is a very stable form of carbon and, therefore, it is a way to sequester CO2 from the atmosphere. While biochar has been produced for thousands of years, it is yet to scale up to a major climate solution. Devonian systems hopes to change that. Dr. Alan Ransil is the co-founder and CEO of Devonian Systems. He studied energy storage materials at MIT where he received his PhD in 2018, and has worked on projects for the MIT Energy Initiative, ARPA-E, and DARPA. He started Filecoin Green, a sustainability initiative for the world’s largest decentralized storage network. He is an advisor to the Global Carbon Reward project, and for the Commons.Earth event series.

In this Climate Chat episode, we interview Climate Foundation's Founder and Executive Director Brian von Herzen about the Climate Foundation's research of "seaforestation," which is a process that accelerates the growth of ocean kelp that results in (1) reducing greenhouse gas emissions, (2) sequesters atmospheric CO2, (3) increases reflective cloud coverage which results in lower global temperatures. Brian Von Herzen, Ph.D., is the founder and executive director of the Climate Foundation, which upholds the vision and the mission to regenerate life in the ocean using Marine Permaculture technology. As Executive Director, Brian leads Climate Foundation’s large-scale seaweed mariculture programs to develop sustainable food, feed and fertilizer value chains, provide ecosystem life support, and sustain blue carbon sinks. Brian graduated magna cum laude in three years from Princeton University with a degree in Physics. He holds a Ph.D. in planetary science from California Institute of Technology where he was awarded the prestigious Hertz Fellowship, and has been awarded numerous patents. After two decades developing system solutions for companies such as Intel, Disney, Pixar, Microsoft, HP, and Dolby, Brian launched the Climate Foundation in order to investigate groundbreaking nature-based solutions to the climate and other environmental challenges. Brian leads an international team of scientists, engineers, technicians, social scientists and seaweed farmers. Currently and most importantly, Brian is leading a successful Marine Permaculture seaforestation demonstration project in the Philippines.

In this Climate Chat episode, host Dan Miller interviews the CEO of Reflective, Dakota Gruener, about her organization's support of Sunlight Reflection Methods (SRM, a.k.a., solar-geoengineering) research. Dakota Gruener leads Reflective, a non-profit climate initiative accelerating the pace of sunlight reflection research. Across a career spanning global health, digital privacy, and climate, Dakota has focused on developing frontier technologies with the potential for worldwide impact—while ensuring the risks they pose are addressed responsibly. Originally trained in biology and political science, she served as aide-de-camp to the CEO of Gavi, the Vaccine Alliance, where she supported negotiations with vaccine manufacturers and helped raise $10B to fund five years of vaccine programs in low- and middle-income countries. She was also founding Executive Director of ID2020, a global alliance committed to ethical, privacy-protecting digital identity and served as co-chair of both the WHO Smart Vaccine Certificate Working Group, which set international standards for COVID vaccination certificates, and the Good Health Pass Collaborative, a private-sector initiative (125+ companies) focused on resumption of international travel. Dakota holds a degree from Brown University and is a proud Californian.

In this Climate Chat episode, we interview climate scientist Francisco Estrada about his recent paper assessing the risks of "Termination Shock" following the implementation of Solar Radiation Management (SRM, a.k.a., solar-geoengineering). Termination Shock is a rapid, severe warming spike that would occur if SRM were suddenly stopped, because accumulated greenhouse gases would heat the planet all at once instead of being masked. Francisco Estrada is a researcher at the Department of Environmental Economics, Institute for Environmental Studies (IVM), Vrije Universiteit Amsterdam. He also works in the Climate Change research group at the Center for Atmospheric Sciences of the Universidad Nacional Autónoma de México (UNAM). His PhD work centered on developing a new global Stochastic Integrated Assessment Model. He obtained a MSc on Risk Management from the Instituto Tecnológico Autónomo de México (ITAM). He was a contributing author for the Working Group II of the IPCC's Fourth Assessment Report and he has been selected as expert reviewer for the Working Group II contribution for the IPCC's Fifth Assessment Report. He has participated and coordinated research projects on the assessment of the potential impacts of climate change in agriculture, the economics of climate change and also on the generation of regional climate change scenarios. His recent paper is "Economic assessment of SRM under socio-political and geophysical tipping dynamics": https://iopscience.iop.org/article/10.1088/2752-5295/ae33df An article about the paper appeared in New Scientist magazine: "Termination shock could make the cost of climate damage even higher": https://www.newscientist.com/article/2513124-termination-shock-could-make-the-cost-of-climate-damage-even-higher/ Follow Francisco on X/Twitter: @festradaCCA Climate Chat SRM/Solar-Geoengineering Playlist: https://www.youtube.com/playlist?list=PLep9tQgCqjCoWPp-16Oxhjt9QPvtynzql Climate Chat programs are available here: https://www.youtube.com/@climatechat/streams Please Like and Subscribe!
