How might an increase in pollution affect cloud formation?

An increase in pollution can significantly affect cloud formation by introducing more aerosols into the atmosphere. These particles serve as cloud condensation nuclei (CCN), which can lead to the formation of smaller, more numerous cloud droplets. This can result in clouds that are less effective at precipitating rain, potentially altering local weather patterns. Additionally, polluted clouds may have different reflective properties, impacting the Earth's energy balance and climate.
