Model of exponential growth in skyglow at one location
Andrej Mohar produced a video modeling skyglow changes from 1950-2040 at Matajur mountain on the border of Slovenia and Italy:
The simulation is based on a calibrated all-sky image taken at the site, with an estimate of 5% annual growth in skyglow (which is a pretty reasonable assumption for the later half of the 20th century). But there's no reason that skyglow must continue growing at such a rate! If we get smart about how, where, and when we light, we could recover the starry skies that many of us remember from our childhood.
