Controlling MCB - Walker Lee Part 1

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

Roll up! Roll up! Grab your buckets, and get ready to do a science! Bach is back (again) to discuss institutional collaboration and citizen science in OAE. Bach, L. T., Ferderer, A.

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/

Is the supply of carbon removal fundamentally limited, and how should it be allocated? Comrade Allanah Paul from Bellona sends @geoengineering1 to the reeducation camps in an attempt to expunge his bourgeois thinking. report: https://www.negemproject.eu/wp-content/uploads/2023/11/D6.5_Who-should-use-NETPS.pdf

Gunter Flipkens explains why everyone is worried about heavy metals leaching from olivine coastal weathering experiments. Then he explains how he tests the exact toxicity to animals, plus how to reduce it.

Christian Claudel comes on to explore the issues around using drones to distribute MCB particles. These are made by anti-solvent precipitation (much like diluting Ricard spirit). Despite @geoengineering1 being AN ACTUAL AUTHOR on the paper he still finds plenty of opportunities for nitpicking.

Michael Fuhr gives @geoengineering1 news on what happens when you throw rocks in the sea (yawn). Then they go on a massive rant about how Gen Z academics don't know how to party anymore (yey!). But which one of them ended a conference locked in a laundry cage being rolled through a hotel foyer? Find out, inside.
