Sulfate aerosols are produced mostly from sulfur dioxide which arises from fossil fuel combustion. Because of their impact on air quality, including its role in acid deposition, efforts to reduce emissions, for example by using scrubbers at coal fired power plants, have succeeded in lowering emissions. Use the Infographic to determine what effect these reductions in emissions would have on climate? a. Sulfate aerosols are negative forcers and thus have a cooling effect.
b. They can scatter incoming light and increase cloud formation and reflectivity.
c. A reduction in emissions would thus have a warming effect on global climate.
d. Sulfate aerosols are also positive forcers and thus have a warning effect.
e. Only A, B, and C are correct.
