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 scenario...

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 atmosp...

In this Climate Chat episode, host Dan Miller talks about what he learned at San Francisco Climate Week and what worried him about optimism bias and the lack of appreciation of accelerated warming and tipping points. He will also discuss some optimistic signs of awareness and solutions. Please Like and Subscribe! Listen to Climate Chat on Apple Podcasts: https://podcasts.apple.com/us/podcast/clima...

In this Climate Chat episode, we interview returning guest René van Westen on his latest Atlantic Meridional Overturning Circulation (AMOC) research, including his research that shows the recent sudden shift of the Gulf Stream is an indication of pending AMOC collapse. Dr. Westen is a postdoctoral researcher at Utrecht University in the Netherlands. René is the author of a number of recent scienti...

In this Climate Chat episode, Cornell climate scientist -- and returning guest -- Douglas MacMartin discusses the latest research in Sunlight Reflection Methods (a.k.a, solar radiation management (SRM) and Solar Geoengineering) and the practicality of implementing SRM in the coming decade, if needed. Douglas MacMartin is an Associate Professor in the Sibley School of Mechanical and Aerospace Engin...

In this Climate Chat episode, Host Dan Miller discusses the Iran war's positive and negative climate impacts, and explains why lower fossil fuel emissions caused by high oil prices due to the Iran war will not lower atmospheric CO2 levels nor reduce global warming. Please Like and Subscribe! Dan Miller has been giving talks around the world on the need for urgent climate action for over 20 years....

In this Climate Chat episode, Hosts Dan Miller and Leon Simons discuss recent research that measured the past 3 million years of greenhouse gases, and ocean heat content, and discuss what it means to our climate future.
