Artificially lit surface of Earth at night increasing in radiance and extent. Transitions to LED lighting greatly increase this “skyglow,” because the clear sky predominantly scatters short-wavelength light.

A much more reasonable and effective solution is best lighting practices that protect people's quality of life, wildlife, and the natural nightscape from inappropriately placed, brightly illuminated billboards.
