Picturing Earth in a New Light...

An analysis of nearly a decade of nighttime lights data (2014-2022) from NASA's Black Marble product revealed areas of brightening (gold) and dimming (purple) shown here across the Eastern Hemisphere.

The researchers found that global radiance increased by 34 percent during the study period, but that surge masks large areas of dimming. Such “bidirectional changes” often happen side by side.

In the U.S., for example, West Coast cities grew brighter as their populations increased, while much of the East Coast showed dimming, which the team attributed to the increased use of energy-efficient LEDs and broader economic restructuring.

The authors concluded that internationally, nighttime light surged in China and northern India along with urban development, while LEDs and energy conservation measures coincided with reduced light pollution in Paris and throughout France (a 33 percent dimming), the UK (22 percent dimming), and the Netherlands (21 percent dimming). European nights dimmed sharply in 2022 during a regional energy crisis that followed the outbreak of the Russia-Ukraine conflict.
