: [geo] Exploring accumulation-mode-H2SO4 versus SO2 stratospheric sulfate geoengineering in a sectional aerosol-chemistry-climate model That's not necessarily true. By the time CE is rolled out, we could be looking at significantly more methane in the atmosphere, due to permafrost.

That's not necessarily true. By the time CE is rolled out, we could be looking at significantly more methane in the atmosphere, due to permafrost. Much ultimately ends up as strat H2O. I vaguely remember more tropospheric folding, too, which also transports water up. Can't remember the reference,

Water in the high lat strat is limiting particle growth. H2O is in the ppm range.  See Hamil, Steele, Toon and Turco's work 1970-2000. On 11/15/2018 1:51 PM, Andrew Lockley wrote: https://www.atmos-chem-phys-discuss.net/acp-2018-1070/ Review status This discussion paper is a preprint. It is
