FALSE

Explanation:

Aerosol are generally tiny particles suspended in the atmosphere. These can both be solid or liquid particles. These aerosols can either reflect or absorb sunlight depending on its properties, but most of the aerosols are "cool" type of aerosol. So, these aerosols generally decrease the overall temperature and work as an important counterbalance of the global warming caused by the greenhouse gases. These aerosols can also change the air circulation patterns by changing the temperatures by differential rate of sunlight absorption. Carbon aerosols like Soot are opposite to this nature. These absorbs the sunlight and make the atmosphere hotter.

At high concentrations these micrometer sized particles can be very much harmful for humans. Air pollutants produced from the burning of the fossil fuels causes approximately 5.5 million deaths worldwide.

So the answer will be false.
