Climate simulations (IMAGE) Kyushu University Caption Simulations using MIROC-SPRINTARS predict annual mean distribution of changes in surface air temperature following reduction of SO2 emissions from fuel sources to 10% of the current level under present (left) and doubled (right) CO2 concentrations. Decreasing sulfate aerosols from human activity at high CO2 concentrations results in enhanced temperature increases, especially in the mid-to-high latitudes of the Northern Hemisphere.
