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

Plus his letter to the International Maritime Organization

Charly Moras explains how grain size affects reaction kinetics in ocean alkalinity enhancement. Paper:- Effects of grain size and seawater salinity on magnesium hydroxide dissolution and secondary calcium carbonate precipitation kinetics: implications for ocean alkalinity enhancement https://egusphere.copernicus.org/preprints/2024/egusphere-2024-645/

In this spooky Halloween episode, @geoengineering1 and Ken Buesseler investigate alleged sightings of Ocean Iron Fertilisation - which is rumoured to have risen from its unquiet grave. Paper: Next steps for assessing ocean iron fertilization for marine carbon dioxide removal. https://www.frontiersin.org/journals/climate/articles/10.3389/fclim.2024.1430957

Kai Jeggle explains to @geoengineering1 how off-target effects of cirrus cloud thinning mean that it can never be used effectively. Paper; Jeggle, K., Neubauer, D., Binder, H., and Lohmann, U.: Cirrus formation regimes – Data driven identification and quantification of mineral dust effect, EGUsphere [preprint], https://doi.org/10.5194/egusphere-2024-2559, 2024.

Got wood? Looking for somewhere to stick it? Ning Zeng can solve your problem! @geoengineering1 learns all about how to do it properly.

Zeng, N., Hausmann, H. Wood Vault: remove atmospheric CO2 with trees, store wood for carbon sequestration for now and as biomass, bioenergy and carbon reserve for the future. Carbon Balance Manage 17, 2 (2022). https://doi.org/10.1186/s13021-022-00202-0

Do not adjust your set; the fidelity of this recording is particularly poor. Luna Geerts and @geoengineering1 discuss coastal enhanced weathering of olivine. The paper is/was open to review, here. https://egusphere.copernicus.org/preprints/2024/egusphere-2024-1824/
