Return to different climate states by reducing sulphate aerosols under future CO₂ concentrations.

ABSTRACT: It is generally believed that anthropogenic aerosols cool the atmosphere; therefore, they offset the global warming resulting from greenhouse gases to some extent. Reduction in sulphate, a primary anthropogenic aerosol, is necessary for mitigating air pollution, which causes atmospheric warming. Here, the changes in the surface air temperature under various anthropogenic emission amounts of sulphur dioxide (SO₂), which is a precursor of sulphate aerosol, are simulated under both present and doubled carbon dioxide (CO₂) concentrations with a climate model. No previous studies have conducted explicit experiments to estimate the temperature changes due to individual short-lived climate forcers (SLCFs) in different climate states with atmosphere-ocean coupled models.
