“…Emergency situations and catastrophic events frequently give rise to sudden changes in emissions [93][94][95]. Emissions may also change after urban lighting remodelling driven by energy savings goals [96,97]. Simultaneously with these human-driven changes in emissions, the highly variable state of the atmosphere (aerosol concentration and types, presence of clouds etc.)…”

Light pollution is the alteration of the natural levels of darkness by an increased concentration of light particles in the night-time environment, resulting from human activity. Light pollution is profoundly changing the night-time environmental conditions across wide areas of the planet, and is a relevant stressor whose effects on life are being unveiled by a compelling body of research. In this paper, we briefly review the basic aspects of artificial light at night as a pollutant, describing its character, magnitude and extent, its worldwide distribution, its temporal and spectral change trends, as well as its dependence on current light production technologies and prevailing social uses of light. It is shown that the overall effects of light pollution are not restricted to local disturbances, but give rise to a global, multiscale disruption of the night-time environment. This article is part of the theme issue ‘Light pollution in complex ecological systems’.
