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.

Dr. Klaus Lackner was one of the first scientists to explore how to remove excess CO2 from the atmosphere. In this wide-ranging masterclass interview, Klaus and host Dan Miller discuss the feasibility, scalability, safety, and cost of large-scale Direct Air Capture (DAC) and sequestration of atmospheric CO2. Klaus Lackner is the director of Center for Negative Carbon Emissions and a professor in the School of Sustainable Engineering and the Built Environment of the Ira A. Fulton Schools of Engin...

Climate scientist David Archer of the University of Chicago discusses his research on the Ultimate Cost of Carbon (UCC): The climate impacts of release CO2 if the negative effects are not discounted. He also discusses the *very* long term impacts that our emissions of CO2 have on the climate (~500,000 years!). David's UCC paper can be accessed here: https://link.springer.com/article/10.1007/s10584-020-02785-4 David's homepage is https://geosci.uchicago.edu/people/david-archer/ Time Stamps: 00:00...

Robert Howarth is Professor of Ecology & Environmental Biology at Cornell University. He is an expert on natural gas & methane and their impact on the climate. In this wide-ranging interview, Prof. Howarth discusses how methane's powerful warming capability (87X more effective than CO2 in warming the world over a 20-year period) and its high leakage rate from the extraction, transportation, and utilization processes makes it about as bad as coal when it comes to short-terms global warming. Prof....

Climate Scientist Kevin Anderson provides a straight-talk & sobering view of our climate situation. How can we stay under 1.5/2ºC warming? What is the role of carbon capture? What does 4ºC warming mean? Have we reached a tipping point in public engagement? How should we think about Earth system feedbacks? Listen to gain insight into the "radical future" that is ahead of us. Part 2 is here: https://youtu.be/iiE5A78jzOg Kevin's homepage: http://kevinanderson.info Warning: This interview presents w...
