Night skies brighten 10% a year as LED lighting adds to light pollution

A Globe at Night study based on 50,000 observations found artificial night-sky brightness rising 10.4% annually in North America and 9.6% globally. Satellites underestimate the effect because they are less sensitive to the blue wavelengths of modern LEDs.
