Light pollution is increasing globally around the Earth, according to the results of a new study published in the journal Nature, Wednesday April 8, but shows a significant decline in certain countries. Drawing on data from NASA’s “Black Marble”, powered by nighttime observations from three satellites (Suomi NPP, NOAA-20 and NOAA-21), a team of American and German researchers was able to establish the most precise mapping of the evolution of light pollution on the surface of the globe from 2014 to 2022.
In nine years, light pollution has increased by 16% on the planet, but this figure is a balance between regions where brightness has increased and where it has decreased. It doesn’t sum up everything. In detail, the African and Asian continents are those where the growth in light pollution has increased the most (respectively + 21% and + 38% over the period), while Europe recorded a drop of 4% in its brightness seen from space.
