In this Climate Chat discussion, we discuss the recent controversy, partially caused by our interview last week with climate scientist Michael Mann, over whether we are at or close to 1.5ºC global average temperature anomaly "trend". While Dr. Mann and others say we are at a trend of about 1.3ºC now, others, including climate scientist James Hansen say we may at 1.5ºC now "for all practical purpos...

In this Climate Chat discussion, Michael Mann joins us to discuss the latest climate science as well as his recent books, Our Fragile Moment and The New Climate Wars. Dr. Michael E. Mann is Presidential Distinguished Professor in the Department of Earth and Environmental Science at the University of Pennsylvania, with a secondary appointment in the Annenberg School for Communication. He is directo...

In this Climate Chat discussion, host Dan Miller will discuss why we continue to choose to fail to act on climate. In last week's episode, Dan discussed his 20-point global climate action plan. While the policies presented are obviously needed, we continue to muddle along without taking serious action even though we know it is needed. Why is that? After Dan put together his policy plan several yea...

In this Climate Chat discussion, host Dan Miller will present a talk he recently gave at the Middlebury Institute of International Studies (MIIS) in Monterey on his proposed 20-point climate action plan. The plan lays out the major policies that governments around the world should implement once they decide to choose to succeed on climate action. You can see a list of the 20-point plan here: https...

In this Climate Chat episode, we interview climate scientist Kevin Anderson for a 2nd time. Out first, audio-only, interview in May 2021 was one of the most listened to Climate Chat programs. Kevin tells it like it is and does not sugarcoat the situation. We will discuss carbon budgets and global temperatures, the desirability of carbon dioxide removal (CDR) and Sunlight Reflection Methods (SRM),...

In this Climate Chat episode we discuss the rapid acceleration of global warming with climate scientist Leon Simons. The Berkeley Earth dataset shows the average global surface temperature in 2023 was +1.54ºC above the pre-industrial average. This is far above previous years and while there was an El Niño starting in 2023, it cannot explain the full jump in global temperature. Leon Simons is a cli...

In this Climate Chat episode we discuss the types of protest and collective action that might be effective in engaging individuals and society to take climate action seriously. Our guest is Dr. Johanna Vollhardt, Associate Professor in the Department of Psychology at Clark University. Dr. Vollhardt’s research focuses on the psychological impact of collective victimization, focusing on questions su...

In this special Climate Chat "Lightning Round" episode we discuss when the Atlantic Meridional Overturning Circulation (AMOC) ocean current -- a major climate tipping point -- will shutdown. While the IPCC says the AMOC is unlikely to shutdown this century, a recent paper co-authored by Peter Ditlevsen says we could see the AMOC shutdown around mid-century... and possibly as soon as 2025! Here is...

In this Climate Chat episode we discuss whether the world will start to take climate action seriously in 2024.

In this Climate Chat episode we discuss the August 2022 paper "Climate Endgame: Exploring catastrophic climate change scenarios" by Luke Kemp, Chi Xu, Joanna Depledge , and Timothy M. Lenton: https://www.pnas.org/doi/10.1073/pnas.2108146119 The paper explores how the IPCC does not include proper risk assessment of catastrophic climate change scenarios and what proper risk assessment may reveal. Fo...

In this Climate Chat episode we discuss the reasons that the world is not reducing emissions even though we are aware of the dangers of inaction and we understand the solutions we must implement. Much of the discussion revolves around climate scientist Kevin Anderson's response to a Guardian article, "Who are the polluter elite and how can we tackle carbon inequality?" https://www.theguardian.com/...

Climate Chat host Dan Miller interviews climate communications host Joe Romm about his recent white paper, "Why direct air carbon capture and storage (DACCS) is not scalable and ‘net zero’ is a dangerous myth" Here is a link to the paper: https://bpb-us-w2.wpmucdn.com/web.sas.upenn.edu/dist/0/896/files/2023/11/DACCS5.0-11-8-23_RommJ.pdf Some of Joe's other recent writings can be accessed here: htt...

Climate Chat: Hansen: How We Know that Global Warming is Accelerating

In this Climate Chat, we discuss James Hansen's new "Global Warming in the Pipeline" paper. In the paper, Hansen shows why the IPCC's Equilibrium Climate Sensitivity (ECS) is too low, and their estimates of aerosol cooling are also too low. This has profound consequences for our climate future. Link to Hansen's paper: https://academic.oup.com/oocc/article/3/1/kgad008/7335889 Link to YouTube video...
