New Global Emissions Projections: Scrapping the Highs & Lows with Detlef van Vuuren
In this Climate Chat episode, hosts Leon Simons and Dan Miller interview climate scientist Detlef van Vuuren about his recent paper where he lays our new "emissions scenarios" that will be used by the IPCC to predict future global warming. Since future temperatures depend on our future greenhouse gas emissions, scientists need to use emission scenarios to predict future temperatures. Past scenarios included what some scientists felt were beyond the possible worst case emissions, as well as scenarios that assumed much less emissions than currently seems feasible. Detlef and his colleagues has…

Biochar Carbon Removal: Finally Ready for Primetime? with Alan Ransil
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…
