Light pollution has been a known issue for decades. But we’ve only recently been able to access the tools and technology to better understand which sources contribute the most to light pollution, and what impact that has on the natural world. In this February 2020 CityLab article, IDA’s Director of Public Policy, John Barentine, draws attention to how a deeper understanding of the sources of light pollution helps IDA develop smarter policies to protect the night.
In the coming weeks, we hope you will take part in the annual Globe at Night campaign. This worldwide campaign asks individuals to measure the quality of the night sky where they live. You don’t have to leave your backyard (or porch or patio) to take night sky measurements, and reporting your results takes only a moment using the Globe at Night online webapp. Your reported measurements are added to other reports from around the world where they are held in an open-source database. With these measurements, scientists can see how the quality of the night is changing all around the world. Your measurements help IDA develop targeted policies and guidelines to help solve the problem of light pollution.
Please take part in the global campaign March 14-24, 2020. Learn how to participate at our Globe at Night page on our website, or click on the link below to watch a short instructional video.
