Trend analyses of sulfur dioxide emissions and sulfate concentrations and their application to global cooling



Sulfur emissions and sulfate concentrations in ice samples obtained from different depths at a site in Southern Greenland are used to infer a relationship between the emissions and sulfate aerosols. In a theoretical model, it was found that this relationship is nonlinear. The upward trend in the sulfate concentrations over the past 100 years is related to a change in cloud droplet concentrations and its impact on global surface temperature. It is estimated that 1.0 to 2ºC of cooling is possible.
