A tiny particle one thirtieth the width of a human hair could be driving pollution and climate change, researchers say.
Harvard University scientists studied atmospheric particles, a highly lethal air pollutant which appears everywhere in the atmosphere, but is more common above cities.
The tiny particles play a key role in air pollution and climate change by providing a surface for chemical reactions and reflecting and absorbing radiation.
This could impact how air becomes polluted and the processes behind climate change - the warming of the earth. ......... ::read more at the link above::

What they don't discuss is just how the particles get there. :) It is simply left to the assumption of the reader that, since they are more common over highly populated areas, they are likely just plain old-fashioned pollution.
