Changing Interhemisopheric Temperature Asymmetry

Caption

The top chart shows the steady rise in Northern and Southern Hemisphere temperature since the beginning of the 20th century. The second chart shows little change in the interhemispheric temperature asymmetry (ITA) until the 1980s, when the effect of sulfate aerosols declined as a result of the Clean Air Act.
