Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories, and, like any other form of pollution, disrupts ecosystems and has adverse health effects. Light pollution is a side-effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, outdoor area lighting (such as car parks), offices, factories, streetlights, and illuminated sporting venues.
Apr 1, 2024 · Light pollution, the excessive or inappropriate use of outdoor artificial light, is affecting human health, wildlife behavior, and our ability to observe stars and other celestial objects. That Earthly Sky Glow. Light pollution is a global issue. This became glaringly obvious when the World Atlas of Night Sky Brightness, a computer-generated map based on thousands of satellite photos, was published in 2016. Available online for viewing, the atlas shows how and where our globe is lit up at night.
The light pollution map has two base layers (road and hybrid Bing maps), VIIRS/World Atlas/Clouds/Aurora overlays and a point feature overlay (SQM, SQC and Observatories). If you want detailed analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends web application (not mobile optimised). For more information view the help.
Jul 6, 2024 · light pollution, unwanted or excessive artificial light. Like noise pollution, light pollution is a form of waste energy that can cause adverse effects and degrade environmental quality. Moreover, because light (transmitted as electromagnetic waves) is typically generated by electricity, which itself is usually generated by the combustion of fossil fuels, it can be said that there is a connection between light pollution and air pollution (from fossil-fueled power plant emissions).

Light pollution is the human-made alteration of outdoor light levels from those occurring naturally. When we over-light, fail to use timers and sensors, or use the wrong color of light, we can negatively affect many parts of our world, including migratory birds, pollinators, sea turtles, and mammals, including humans. Light can be a pollutant.
Feb 14, 2023 · Light pollution is caused by artificial light sources such as street lamps, houses, and skyscrapers. Efforts are being made globally to reduce light pollution, including education campaigns and the use of smart lighting controls and shielded lamps. Humans are naturally afraid of the dark. We sometimes imagine monsters under the bed and walk faster down unlit streets at night. To conquer our fears, we may leave a night light on to scare away the monsters and a light over the porch to deter ...

Jun 15, 2022 · 1. Light pollution interrupts wildlife patterns and harms biodiversity. Birds, bats and insects are among those in the natural world affected by light pollution, studies show. Migratory birds rely on natural light to guide them and interruptions can lead to collisions and incorrect navigations on their long-distance journeys.
Feb 20, 2024 · Light pollution may seem like a secondary issue compared to other climate change impacts, but it's easy to reduce. Simply dimming outdoor lighting or directing it only where necessary would make a big difference, said David Welch, lead author of the report and chair of the Dark Skies Advisory Group. Other solutions include changing the color temperature of outdoor lightning. Light in the blue part of the spectrum — the kind often emitted by LEDs — is especially harmful.

Light pollution comes in many forms, including sky glow, light trespass, glare, and over illumination. Sky glow is the bright halo that appears over urban areas at night, a product of light being scattered by water droplets or particles in the air. Light trespass occurs when unwanted artificial light from, for instance, a floodlight or streetlight spills onto an adjacent property, lighting an area that would otherwise be dark. Glare is created by light that shines horizontally.
