Earth’s night lights rise, but the glow flickers with policy and conflict

NASA-funded study of 1.16 million satellite images shows artificial night lighting increased about 16% globally from 2014–2022, but regional shifts were volatile: Europe dimmed significantly due to efficiency rules and energy shortages, Venezuela dropped after economic collapse, while Asia continued to brighten; the United States saw mixed signals with West Coast growth and East Coast dimming; gas flaring in central US highlighted energy waste; overall radiance rose but with a patchwork of bright and dim regions, reflecting policy, economy, and conflict.
