Satellite Study Reveals 16% Global Light Pollution Increase from 2014-2022

A report published in Nature indicates that light pollution surged by 16% globally between 2014 and 2022, as analyzed through NASA's Black Marble satellite data. Zhe Zhu, the lead author from the University of Connecticut, describes nighttime brightness as 'flickering,' with the rise largely attributed to developing nations such as India and China. In contrast, Europe is experiencing a decrease due to various policies. Areas with reduced brightness are expanding due to energy conservation initiatives and conflicts. Satellite images reveal changes in light patterns influenced by events like COVID-19 restrictions. Furthermore, a 2023 study estimates an annual increase in light pollution of 10%. Both studies highlight detrimental effects on wildlife and human sleep, with France managing to lower pollution levels while Asia faces significant rises.
