Q4 Along with producing GHGs, human activity also puts many kinds of aerosols into the atmosphere. What is the sign of their radiative forcing?

Positive

Negative

Negative

Explanation:

Aerosol -

It is the suspension of the solid or liquid particles in the air, is known as the aerosol.

The effect of aerosol is, that it reduces the amount of the solar radiations incident on the surface of the Earth, and due to this capacity to reflect the solar radiations, it has a negative impact on the Earth.

As we known solar energy are of huge importance for the human beings.

Hence, the answer is negative.
