Predict what affects aerosols may have on climate change.

Two different ways direct radiative forcing the scattering of solar radiation and the absorption/emission of terrestrial radiation. Indirect radiative forcing, mainly by effects of aerosols on cloud properties. Greenhouse gases effect on the global radiative balance and surface temperatures. The effect of aerosols on clouds is highly speculative. If more aerosol, the smaller the cloud droplets tend to be, and clouds with more but smaller drops have a higher albedo.
