Factors Associated with Climate Change

Radiative Forcing

Pollutants That Cool the Atmosphere

Atmospheric Aerosols Both human and natural sources Tiny particles (or sulfur) that remain in

troposphere for weeks or months Sulfur-laden layer in the atmosphere reduces the

amount of sunlight reaching earth Complicates models of climate change
