Pollution Playing A Major Role In Sea Temperatures : NPR

Aerosols are fine particles like soot or sulfur compounds, mostly from burning fuel. They seed a kind of cloud that's especially good at reflecting solar radiation back into space. Even on their own, without clouds, these aerosols act like sunblock.

Volcanoes create aerosols, too, but air pollution appears to produce more, and then the aerosols sweep across the Atlantic sky.
