PNNL: increases in aerosols from East Asia decreased effects of reductions in US emissions in western states by 25%

By mmillikin A study led by scientists at the US Department of Energy’s Pacific Northwest National Laboratory found that, in the western United States, increases in aerosols from East Asia decreased the radiative warming effect induced by reductions in US emissions by 25% from 1980-2014. The open-access study appears in the AGU journal Earth’s Future.

Because they can either absorb or reflect energy, aerosols are important components influencing air quality and atmospheric changes. Quantifying the source of aerosols and their influence on energy balance is necessary for predicting future air quality and Earth system changes. As industrial aerosols decrease in the United
