Geoengineering Is Going to Happen
2023-08-11 in Ryan CooperIn my last paid issue here, I discussed the virtual certainty that a heat wave megadeath disaster is going to happen at some point. Heat already kills more people than any other kind of natural disaster, and many places are already creeping up to the limit at which even young,

The Future Is the Termination Shock: On the Antinomies and Psychopathologies of Geoengineering. Part One
2023-06-29 (or before) in BrillAbstract As capitalist society remains incapable of addressing climate breakdown, one measure is waiting in the wings: solar geoengineering. No other technology can cut global temperatures immediately. It would alleviate the symptoms of the crisis, not its causes. But might it be combined with radical emissions cuts? This essay, the first instalment of two, scrutinises the rationalist-optimist case for geoengineering: the idea that soot planes in the sky can shield the Earth from the worst heat while society rids itself of fossil fuels. A more likely outcome is that they encourage business-as-usual to continue, while negative si...

Global warming in the pipeline
2023-03-31 (or before) in arXiv.org e-Print archiveImproved knowledge of glacial-to-interglacial global temperature change implies that fast-feedback equilibrium climate sensitivity is at least ~4°C for doubled CO2 (2xCO2), with likely range 3.5-5.5°C. Greenhouse gas (GHG) climate forcing is 4.1 W/m2 larger in 2021 than in 1750, equivalent to 2xCO2 forcing. Global warming in the pipeline is greater than prior estimates. Eventual global warming due to today's GHG forcing alone -- after slow feedbacks operate -- is about 10°C. Human-made aerosols are a major climate forcing, mainly via their effect on clouds. We infer from paleoclimate data that ae...

Mechanism of ozone loss under enhanced water vapour conditions in the mid-latitude lower stratosphere in summer
2023-02-01 (or before) in ACP - Atmospheric Chemistry and PhysicsAbstract. Water vapour convectively injected into the mid-latitude lowermost stratosphere could affect stratospheric ozone. The associated potential ozone loss process requires low temperatures together with elevated water vapour mixing ratios. Since this ozone loss is initiated by heterogeneous chlorine activation on liquid aerosols, an increase in sulfate aerosol surface area due to a volcanic eruption or geoengineering could increase the likelihood of its occurrence. However, the chemical mechanism of this ozone loss process has not yet been analysed in sufficient detail and its sensitivity to various conditions is not yet cl...

An Indigenous Group’s Objection to Geoengineering Spurs a Debate About Social Justice in Climate Science - Inside Climate News
2021-07-07 in Inside Climate NewsIt was February in northern Sweden and the sun was returning after a dark winter. In the coming months the tundra would reawaken with lichens and shrubs for reindeer to forage in the permafrost encrusted Scandinavian mountain range. But the changing season also brought some unwelcome news to the Indigenous Sámi people, who live across […]
