How can aerosols affect climate?
Answer and explanation
Correct answer: Both radiation and cloud formation
Aerosols are tiny solid or liquid particles suspended in the atmosphere. Directly, they can scatter incoming sunlight back to space or absorb radiation, altering the amount of energy reaching the surface. Indirectly, they can act as cloud-condensation nuclei, changing cloud droplet number, cloud brightness, lifetime and precipitation. Their overall climate effect may be warming or cooling depending on composition, altitude, location and interaction with clouds.
