Earth’s night skies continue to get brighter despite efforts of groups to reduce the effects of artificial lighting. One particular group, the International Dark-Sky Association has campaigned for decades to reduce artificial light at night. Yet a new study shows our night skies are still brightening at a yearly rate of 2 percent.

A study shows a possible correlation between some economically developing nations and their brighter night skies. The study also noticed zero decline in light pollution rates in already-developed nations, despite them currently switching to energy-saving LED lighting, which was originally thought by some to reduce effects of lighting.

Bottomline: The study shows that light is growing in places that didn’t have much lighting to begin with. Which means that the fastest rates of increase are occurring in places that so far hadn’t been very strongly effected by light pollution in the past.
