How Aerosol Driven Water Droplet Concentrations Control Low Level Cloud Coverage Affecting Climate

In a nutshell, with more aerosols (particles and non-water liquids) in the atmosphere, there are more cloud condensation nuclei so many more and smaller water droplets in clouds. Thus clouds are much more reflective of incoming sunlight, causing some cooling to partially offset GHG warming. Smaller water droplets in clouds means that they rain less, become thicker, hold more water, cover a larger fraction of the sky and persist for a lot longer causing even more cooling offset. With global industrial shutdowns from our coronavirus responses, we have less aerosols in the skies, thus less of this cooling offset occurring.
