That’s the fascinating theory behind a new study that analyzes paintings going back to the 1500s to study the way atmospheric pollutants impact the climate. Specifically, researchers at Greece’s Academy of Athens say, they were able to use depictions of sunsets to measure something called aerosol optical depth (AOD), a measure of particles, or aerosols, in the atmosphere. Back before the industrialized era, those particles could include things like dust, smoke and, most significantly, volcanic ash. These day, industrial pollutants are added to the mix.
