the main reason behind this mid-century cooling was global dimming due to anthropogenic sulfate aerosol emissions.

although the temperature drops foreseen by this mechanism have now been discarded in light of better theory and the observed warming, aerosols are thought to have contributed a cooling tendency (outweighed by increases in greenhouse gases) and also have contributed to "global dimming."
