Wood Vaulting - Zeng

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/

What would a mid-century polar geoengineering program look like? What airports and aircraft would be needed - and at what cost? Wake Smith answers all these questions.

How does SAI affect extra-tropical cyclones? Michelle Simões Reboita explains during a tight interview slot, but @geoengineering1 fails to understand (it takes him at least an hour to understand ANYTHING). With fluency approaching that of the Trump Biden debate, he stumbles through the episode, only occasionally realising where he is and what he's doing. Can anyone do a better job? Please tweet us, if you can... Please?

What control can we exercise over MCB? Should it be confined to small, climatically sensitive areas - or expanded at great cost, to minimise inter-regional disparities? Walker Lee discusses the issue in depth. (See PT 2 for a discussion on disability and diversity). Jack's first paper: https://doi.org/10.22541/essoar.171322700.02512514/v1 Jack's second paper: https://doi.org/10.22541/essoar.171201044.45268441/v1

We've extracted this very interesting discussion from Walker Lee's new episode, because a) it's a standalone section and b) the main episode was already quite long. Here, Walker Lee describes in vibrant and very personal terms his own academic journey, touching on important issues of ideological diversity and disability discrimination. It's not trad R2, but we liked it. Enjoy!

Moritz Günther tries valiantly to get @geoengineering1 to understand the atmospheric dynamics of SAI's impacts on the warm pool, but it's rather like watching him trying to train a baboon to use Photoshop - there's some engagement, and the occasional flash of comprehension before it all gets too much for him. NB this is the FIXED version - the original had a couple of important errors of sign from Günther. If you've listen to the old version, pls see this important author note "the part where I say it's destabilising... should actually be stabilising... roughly at 1:10:30 - 1:11:00. The part where I say we would need less aerosol if the Brewer-Dobson circulation mechanism exists but we would actually need more is around 1:21:30 - 1:22:00." (timestamps from old episode) And BTW, props to him for a) checking b) fessing up. Science progresses one correction at a time.

William Morrissey explains how SAI could lead to conflict and counter-geoengineering. @geoengineering1 isn't convinced it will all end so badly. Avoiding atmospheric anarchy: Geoengineering as a source of interstate tension William Morrissey https://doi.org/10.1177/27538796231221597

How do you establish and grow a DAC company? Anca Timofte has utilised a career leg-up from Climeworks to start her own DAC outfit, with some pretty fancy chemistry. @geoengineering1 gets the lowdown on how she did it - and what the future challenges are https://theholocene.co/
