  • Determines the causes of twentieth century temperature change in six separate land areas of the Earth by carrying out a series of optimal detection analyses
  • Detects the warming effects of increasing greenhouse gas concentrations in all the regions examined, including North America and Europe
  • Finds that, in most regions, cooling from sulfate aerosols counteracts some of the greenhouse warming, and there is some evidence for reduced net aerosol cooling in Asia, possibly as a result of warming from black carbon
