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.

Is OIF undead? - Buesseler
Tuesday, October 15, 2024 • Duration 58:15
In this spooky Halloween episode, @geoengineering1 and Ken Buesseler investigate alleged sightings of Ocean Iron Fertilisation - which is rumoured to have risen from its unquiet grave.

Getting it up - Wake Smith
Tuesday, July 12, 2022 • Duration 01:06:03
Wake Smith explains two recent papers on aviation to @geoengineering1. The first deals with low altitude (13kms) polar deployment, using existing aircraft concepts. The second deals with deployment at 25kms, which adds cost and complexity over the usual 20kms injection patterns in the literature.
