2 days ago · Aerosols come in many shapes and sizes, from dust and soot to tiny particles invisible to the eye. They have many natural sources, such as forest fires and dust storms. But since the Industrial Revolution the aerosol load in the atmosphere has been dramatically increased by anthropogenic sources, primarily the burning of fossil fuels such as ...
