Reviewer 2 does geoengineering

Linquan Mu and Jamie Palter explain the limitations of adding quicklime to rivers. Preprint paper: Considerations for hypothetical carbon dioxide removal via alkalinity addition in the Amazon River https://egusphere.copernicus.org/preprints/2023/egusphere-2022-1505/

Why sign SRM treaties? What makes them stable and useful? Do they need to be stated, or are norms enough? Niklas Lehmann tries to convince a skeptical @geoengineering1 of the usefulness of game theory for modelling key questions in international relations. Paper: Exploring the stability of solar geoengineering agreements

David Morrow returns! He discusses his unconventional transition from philosophy to integrated assessment modelling. @geoengineering1 gets schooled on how the GCAM model was modified to incorporate different CDR technologies, with varying levels of realism. Paper: "GCAM-CDR v1.0: enhancing the representation of carbon dioxide removal technologies and policies in an integrated assessment model" https://gmd.copernicus.org/articles/16/1105/2023/

Is it practical and sensible to turn deserts into forests, using desalination & irrigation? Upeksha Caldera discusses her new paper with @geoengineering1. Paper "Afforesting arid land with renewable electricity and desalination to mitigate climate change" (https://www.nature.com/articles/s41893-022-01056-7).

Naser Mahfouz explains some big problems with MCB to @geoengineering1. Can we fill in the knowledge gaps, before it's too late to use MCB? Paper: "The Radiative and Cloud Responses to Sea Salt Aerosol Engineering in GFDL Models" (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL102340)

How can we merge the concepts of slippery slopes and the precautionary principle? James Andow explains how precautionary evaluation of risks can help us evaluate both the risks of ending up on a slippery slope to deployment, and the risks resulting from deployment. James argues that we need to concern ourselves with risks, not just inevitabilities, when considering slippery slopes. For additional reading discussed, see books "Innate" and "the WEIRDest people in the world". Paper: "Slippery Slope Arguments as Precautionary Arguments: A New Way of Understanding the Concern about Geoengineering Research" (https://www.ingentaconnect.com/content/whp/ev/pre-prints/content-whp_ev_3729)

Un-do spreads crushed basalt on farms, and sells the carbon removals to Frontier. @geoengineering1 has concerns about scaling.

Andreas Hein entertains @geoengineering1 with more barmy space-based geoengineering nonsense. Expect moon dust, rail guns, space junk, cube sats and all sorts of other semi-relevant distractions. Paper: Transparent occulters: A nearly zero-radiation pressure sunshade to support climate change mitigation

Peter Fiekowsky and @geoengineering1 discuss Iron Salt Aerosols. Do they work (in 14 different ways)? How can we know? Is Peter's new voluntary regulation body bona fide, or hopelessly compromised? Reviewer 2 asks all the important questions, but doesn't necessarily get definitive answers.

What counts as a tree, and how do you count trees? What do you do when you're surprised by a grizzly bear? How do you get data from despots? Will AI replace humans, when it comes to analysing ecological data? Do ecologists hibernate in winter? Jingjing Liang from Purdue answers all these questions, and more.
