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

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

Can natural ocean processes help us understand how ocean CDR might work? Discussion of "Seeking natural analogs to fast-forward the assessment of marine CO2 removal " with Lennart Bach and @geoengineering1 https://doi.org/10.1073/pnas.2106147118

Does the carbon footprint of Direct Air Capture negate its environmental benefits? Balint Simon discusses his paper, "Material flows and Embodied Energy of Direct Air Capture". This episode was presented by (genuine expert) guest Reviewer 2 Matteo Gazzani, who even seemed to have read the paper! 10.33774/chemrxiv-2021-bpg5d

Julian Hunt relives the highest of high modernism with his cold war style project to divert northern rivers and deliberately melt the Arctic. This will apparently help global warming - or so he says. Paper: Cooling down the world oceans and the earth by enhancing the North Atlantic Ocean current. SN Applied Sciences DOI: 10.1007/s42452-019-1755-y [pure.iiasa.ac.at/16202]

Nan Wang explains why bigger CCS projects are more likely to fail. "What went wrong? Learning from three decades of carbon capture, utilization and sequestration (CCUS) pilot and demonstration projects"

News from @gfuterman and @geoengineering1 covering IPCC, Holly Jean Buck & tribalism, Australian MCB trials, Andy Parker on slippery slope, and much else

Global Thermostat founder Peter Eisenberger steamrollers Andrew (@geoengineering1) in this challenging interview about his company's controversial culture, and its relationship with Exxon.

Comrade Rinberg and Comrade Bergman discuss their revolutionary alkalinity concentration swing CDR. This will be deployed after they've organised an uprising to replace the borgeois capitalist hegemony. @geoengineering1 wishes they'd just get on with making some cash out of their idea, so we can all get it sooner.

How do ethics considerations affect the choices made by researchers as they propose and optimise geoengineering models? Paper link: https://www.sciencedirect.com/science/article/abs/pii/S0039368121000182
