Sentences with phrase «aerosol particles influence»

Aerosol particles influence Earth's climate through cloud formation: Clouds can only form if so - called cloud condensation nuclei (CCN) are present, which act as seeds for condensing water molecules.

The question is: Does the current load of aerosols in the atmosphere already exceed that limit, in which case adding extra particles should not greatly affect cloud formation; or do they continue to be a limiting factor as pollution rises, so that added aerosols would continue to influence the clouds?
