Loss of the night: Light pollution rising rapidly on a global scale

Artificial lighting at night is contributing to an alarming increase in light pollution, both in amount and in brightness, affecting places all over the world, a new study has found.

Some regions have showed a steady increase in light pollution aligned with economic development, but more developed nations that were thought to be "going dark" by switching to energy-saving LEDs showed no apparent decline in their rates of light pollution.

Globally, there has been a push toward more energy- and cost-efficient light sources, such as LEDs, but this has directly contributed to an alarming increase in light pollution, the researchers believe.

Using the first calibrated satellite radiometer for night lights, which can detect radiance, a team of scientists found a 2.2% increase in the Earth's outdoor artificial lighting each year between 2012 and 2016.





long article but a good read. i've also noticed this problem indoors too, thanks to more and more manufacturers believing that u can't make anything that uses electricity without at least one LED that's always on.
