Reviewer 2 does geoengineering

Reviewer 2 quibbles with actual experts in Solar Radiation Modification and Carbon Dioxide Removal, before rejecting their work on spurious, spiteful and capricious grounds. You'd expect nothing less from R2.

Episodes

Biochar stability - Hagemann 26.06.2023

What gives biochar its stability? How dependable is its carbon sequestration in soil? How can we optimise its source materials and manufacturing process, to store the maximum amount of carbon? Nikolas Hagemann explains his paper "Permanence of soil applied biochar." https://www.biochar-journal.org/en/ct/109-Permanence-of-soil-applied-biochar

Trapping CO2 into synthetic salts - Yavuz 15.06.2023

SRM treaties - Lehmann 20.03.2023

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 https://econpapers.repec.org/paper/arxpapers/2210.09145.htm - Niklas V. Lehma...

Adding CDR to GCAM IAM - Morrow 18.03.2023

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" htt...

Foresting the deserts - Caldera 09.03.2023

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).

Does MCB actually work? Mahfouz 02.03.2023

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)

Slippery slope meets precautionary principle - Andow 02.03.2023

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...

Un-do commercial enhanced weathering 02.03.2023

Accepted Author Manuscript e13343. http...

CHALLENGING CLIMATE TAKEOVER - BARRIER REEF MCB 09.02.2023

Good morning, Reviewer 2 listeners. This is Pete Irvine from Challenging Climate. I've been a little disappointed by the Reviewer 2 crew starting a turf war with us, so I've decided to finish it. Today, Jesse and I have paid their studios a little visit - and it's safe to say I don't think we'll be having much trouble from Reviewer 2 in future. Right now, Jesse has @geoengineering1 down in the bas...

Local cooling, SAI, & CDR - Baiman 04.02.2023

Reviewer 2 reluctantly agrees to dish out another drubbing to "radical" economist Ron Baiman. @geoengineering1 discusses Ron's new paper on balancing short-term cooling - both local and global - with long-term CDR.
