The Atlanta metropolitan area benefited greatly from the passing of the Clean Air Act of 1970 in the United States, Professor Jeremy Diem of the Georgia State University says.

More precisely, it appears that this city and its surrounding areas have experienced an increase in local rainfall as a result of the new air quality standards listed under the Clean Air Act.

The professor reached this conclusion after analyzing summer rainfall data compiled between the years 1948 and 2009.

He explains that, as far as he can tell, rainfall in the Atlanta metropolitan area upped to a noteworthy extent in the late 1970s. He suspects that this happened because of the decrease in local air pollution.

“Really, the only plausible reason for this increased rainfall is the reduced pollution due to the passage of the Clean Air Act. This probably happened in many cities other than Atlanta,” Professor Jeremy Diem reportedly said.

His findings are backed up by several previous studies which show that high concentrations of air pollutants tend to suppress rainfall.
