Littoral weathering & academic culture - Fuhr

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. J., LaRoche, J., and Schulz, K. G.: Technical note: Ocean Alkalinity Enhancement Pelagic Impact Intercomparison Project (OAEPIIP), EGUsphere [preprint], https://doi.org/10.5194/egusphere-2024-692, 2024 Identifying the Most (Cost-)Efficient Regions for CO2 Removal With Iron Fertilization in the Southern Ocean Lennart T. Bach, Veronica Tamsitt, Kimberlee Baldry, Jeffrey McGee, Emmanuel C. Laurenceau-Cornec, Robert F. Strzepek, Yinghuan Xie, Philip W.

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. Paper: Marine-cloud brightening: an airborne concept Christian Claudel, Andrew John Lockley, Fabian Hoffmann and Younan Xia DOI 10.1088/2515-7620/ad2f71

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. Paper https://doi.org/10.3389/fclim.2024.1338556 This article is part of the Research Topic Quantifying Carbon Removal by Negative Emissions Technologies Alkaline mineral addition to anoxic to hypoxic Baltic Sea sediments as a potentially efficient CO2-removal technique

What could be the eventual scale of the CDR market? What technologies will it use? And how do choices made today affect where it ends up? Robert Hoglund discusses with @geoengineering1 Some works discussed CDR.fyi annual report https://www.cdr.fyi/blog/2023-year-in-review Carbon removal is not a finite resource https://marginalcarbon.substack.com/p/carbon-removal-is-not-a-finite-resource Emergent methane mitigation and removal approaches: A review Ishita Mundra, Andrew Lockley https://doi.org/10.1016/j.aeaoa.2023.100223

Joshua Schwarz explains how dispersing ice nucleating particles in one tiny region of the tropical tropopause layer off Northern Australia can address around 1pc of global warming. He also discusses his involvement in the SABRE stratospheric flights. Paper: Considering intentional stratospheric dehydration for climate benefits DOI: 10.1126/sciadv.adk0593 Other papers discussed Pyrocumulonimbus affect average stratospheric aerosol composition J. M. KATICH DOI: 10.1126/science.add3101 Marine-cloud brightening: an airborne concept Christian Claudel, Andrew John Lockley, Fabian Hoffmann and Younan Xia DOI 10.1088/2515-7620/ad2f71

What is nature? Does it matter beyond its direct usefulness? Do animals only have rights if they're conscious? When did man become morally responsible for environmental degradation? When can and should we fiddle with the natural world? Elliott Woodhouse explains the differing views to @geoengineering1. A blog post is available, summarising his PhD https://www.sheffield.ac.uk/lc3m/blogs/phd-spotlight-elliott-woodhouses-ethics-climate-engineering
