Prof. Peter Wadhams | Can we remove billions of tonnes of CO2? And methane?

In this ClimateGenn episode, I am speaking to professor Peter Wadhams from the University of Cambridge about his recent research for a book he is writing on the viability of greenhouse gas removal from the atmosphere.

Some of these proposals are also referred to as negative emissions technologies, or ‘nets’  and are widely included in national emissions reduction plans despite none being proven at scale today.  We discuss the viability of various proposed techniques including tree planting, bioenergy capture and storage as well as direct air capture and ocean proposals including farming kelp and the use of diatoms for large-scale sequestration.  In the last segment we discuss the risks posed by Arctic methane releases and two proposed techniques for dealing with a potential methane emergency, whereby multiple   billions of tonnes of the potent greenhouse gas are released at once.   These are controversial proposals despite policymakers assuming they will work in the future. The danger of these suppositions is compounded by the fact that many research projects are embryonic and underfunded.   Thank you for listening. 

In the next episode, I speak with author Professor Tom Rosenstiel about his new political thriller, The Days To Come. In this interview, we discuss fiction writing and journalism and how these both intersect with reality to shape our world.  You can subscribe on all major podcast channels or Youtube and you can also support my work via Visit for more information.  Thanks for listening.
