Covid, light pollution regulations and faltering global economy affect location and intensity of brightness

Earth continues to get brighter every year, researchers have found, but the location and intensity of the progression has become increasingly volatile because of Covid-19, regulations on light pollution, and a faltering global economy.

Nasa-funded researchers at the University of Connecticut (UConn) studied more than 1.1m satellite images taken over a nine-year period to establish that the planet’s artificial light increased by a net 16% between 2014 and 2022.
