Aerosols influence climate both directly by scattering/absorbing radiation and indirectly by affecting cloud properties. While some aerosols warm, the dominant effect of industrial aerosols is cooling, which partially offsets global warming.
The effects of aerosols on climate is/are a. They directly reflect sunlight back to space. b. They indirectly make clouds brighter reflectors. c. Aerosols have a net cooling effect on climate systems. d. Human generated aerosols offset the impact of global warming to some extent. Which of the above effects is/are true ?
