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" https://doi.org/10.1016/j.enpol.2021.112546

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.
