How does mineral dust affect the climate? (Slight cooling, but it's complicated) What do background variations in dust levels teach us about the likely effects of SRM & CDR? (Lots) Should we try to reduce anthropogenic mineral dust? (Probably not) How does reindeer poo fit into all of this? (You'll have to listen) Jasper Kok speaks to @geoengineering1 about his paper "Mineral dust aerosol impacts on global climate and climate change." https://www.researchgate.net/publication/367207625_Mineral_dust_aerosol_impacts_on_global_climate_and_climate_change
