Scientists say Atmosphere Particles could be responsible for cloud-seeding in our sky
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.
