Gernot Wagner talks about genocide, death threats, and the corruption of academia. He's not a man you want to mess with. So, when he tries to sell you his book, you're going to do exactly as you're told. Understand?
Pete Irvine is a stalwart of SRM. Here, he makes the case for its continued consideration as a policy option. This comes at a time when ongoing research on SRM is being subject to one of its most determined challenges yet.
Soheil Shayegh tries and fails to convince @geoengineering1 that abstract models of international cooperation offer useful insights into the behaviour of nations. Paper https://link.springer.com/chapter/10.1007/978-3-030-72372-9_10 Regulating Geoengineering: International Competition and Cooperation Soheil Shayegh, Garth Heutel, Juan Moreno-Cruz
Aaron Cooper @AMCooper86 and Gideon Futerman @GFuterman discuss the International Non-Use Agreement on Solar Geoengineering letter from https://www.solargeoeng.org/ @SolarGeoeng
The Cornell Mafia are taking over the Arctic. Walker Lee explains how their high-latitude, low-altitude scheme works. It's an offer you can't refuse.

Sara Vicca schools @geoengineering1 on biotic silicate weathering. He, meanwhile, screws up the audio production to previously unimagined levels of dire incompetence.
Amanda Borth from George Mason discusses whether geoengineering is covered effectively in the media. Reviewer 2 recalls his days of freelance writing, and paints a far less rosy picture of both the media and its cosy political relationship with academia. Paper link https://doi.org/10.1080/17512786.2021.2002711
Can your humble bathroom mirror be the basis of a terrestrial solar geoengineering scheme? Ye Tao looks at scaling this simple solution - with the surprise bonus of a huge reduction in solar energy costs, when compared to sulfur aerosols.
What are the social and political barriers to scaling CDR? Symons and @geoengineering1 discuss first-movers and a public goods framing. They then consider obstructions to progress: carbon accounting, climate justice, tech investment, and financial incentives.

Mariia Belaia is an economist, who used the Dynamic Integrated Climate-Economy (DICE) model to argue that over half of climate change may optimally be addressed using SRM. @geoengineering1 is so horrified that he turns into an actual commie, live on air. Paper reference: OPTIMAL CLIMATE POLICY IN 3D: MITIGATION, CARBON REMOVAL, AND SOLAR GEOENGINEERING MARIIA BELAIA, JUAN B. MORENO-CRUZ and DAVID W. KEITH https://doi.org/10.1142/S2010007821500081
David Mitchell explains cirrus cloud thinning in detail, and why climate models without mountains get it badly wrong. There is no paper reference here, but there are some hard lessons about the peer review process! NB this episode has been clumsily edited to disguise various errors made by @geoengineering1
