New study highlights the need for urgent action to reverse runaway light pollution


An alarming new study based on data from NSF's and NOIRLab's Globe at Night program concludes that light pollution is increasing at an astounding rate. This rapid brightening of the night sky over large portions of the Earth has serious consequences for all living things. The authors conclude that “existing lighting policies are not preventing this increase, at least on continental and global scales.” The startling increase in light pollution is a clear wake-up call for policymakers that decisive and immediate action is needed to address this urgent environmental threat.
