Britta Clark schools @geoengineering1 on "How to argue about solar geoengineering". This will only encourage him, and generally make him even more insufferable in future. https://onlinelibrary.wiley.com/doi/abs/10.1111/japp.12643
Cameron Wood shows experimentally how phosphate fertilizers catalyse silicate weathering, but the lack of a techno-economic analysis (TEA) leaves @geoengineering1 with questions.

How do you compare biochar to DAC, or afforestation to enhanced weathering? Plug all the details into Solene Chiquier's galaxy brain, that's how. She's like the Oracle of Delphi (but much less weird).

Donn Viviani & Dan Galpern look at how individual petitioners could put an end to US firms' deployment of SRM. Background info provided by guests: Current petition and lawsuit available at cprclimate.org In my 2015 petition I explicitly asked for a section 4 rule to develop data, if EPA lacked the information to make a risk finding. It could serve as a template for a geoengineering information request https://www.epa.gov/sites/default/files/2015-09/documents/petition_oa_tsca_2014_final_2.pdf...

This isn't really a Reviewer 2 episode, it's just some audio we had lying around. We decided to use it, as we have been too lazy to do a proper episode.
Robert was too lazy to to write a paper, but his blog got quite a lot of attention, so we let him on. Blog: What is the value of temporary carbon removal? https://roberthoglund.medium.com/is-there-value-in-temporary-carbon-removal-84aa69a7c428

Could SRM trigger a catastrophe that kills billions? Aaron Tang @aawktang and Gideon Futerman @GFuterman treat this subject with the seriousness you'd expect from Reviewer 2, as they giggle their way through the episode like a couple of tipsy, potty-mouthed schoolgirls.
