Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

In climate models, if you simulate the world with sulfur emissions from shipping, and you simulate the world without these emissions, there is a sizable cooling effect from changes in the model clouds due to shipping. The calculated concentration of cloud droplets without emissions along the shipping route (yellow line).
