Artificial light at night has become a form of environmental pollution – light pollution. In this talk I will give insights into the topic from an ecological perspective and then focus on winter light pollution. I will report on “snowglow” – skyglow amplified by snow that outshines the full moon, and an expedition to the Arctic Circle during polar night featuring frozen lakes, icy roads, ice pillars and auroras.

The ALAN conference series is dedicated to examining all aspects of artificial light at night. The broad scope of the conference includes how light is produced (e.g. technologies, industry, and lighting design), where it is present (e.g. remote sensing); what effects it has on humans and the environment (e.g. ecology); how it is perceived by the public (e.g. perceptions of safety and security), and how the benefits and detriments of lighting may be balanced by regulation.
