Global Light Pollution Rises 16%

Summary

A decade-long satellite study found that global light pollution increased by 16% between 2014 and 2022, presenting a significant challenge for astrophotographers. While developing countries largely contribute to this rise, the research also highlights positive impacts of policy interventions. Notably, France has seen a 33% reduction in light pollution due to new regulations, suggesting that targeted policies can effectively mitigate artificial light. Despite these promising signs, the US continues to experience an overall increase in light pollution.

Key points

• Global light pollution increased by 16% from 2014 to 2022.
• Astrophotographers face growing challenges due to increased artificial light.
• Policies to reduce light pollution are showing positive results in some regions, like France.
• Developing countries are major contributors to the overall increase in light pollution.
