Juliet Kirby explains how gentoo.earth uses AI to match carbon removal buyers and sellers. Despite @geoengineering1 trying his best to wind her up for lulz, she doesn't break character. NB this isn't paid promotion; gentoo hasn't sponsored this episode. No penguins (gentoo or otherwise) were harmed in the making of this episode.

Ron Baiman discusses his expansive paper summarising all known SRM and other direct climate cooling techniques
