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

Green Car Congress

The result implies that globally, cloud changes caused by particles from all forms of industrial pollution block 1 Watt of solar energy per square meter of Earth’s surface, masking almost a third of the present-day warming from greenhouse gases. This path is also part of a popular open-ocean shipping route between Europe and Asia.
