Contrasting trends in light pollution across Europe based on satellite observed night time lights

摘要: Since the 1970s nighttime satellite images of Earth from space have provided a striking illustration extent artificial light. Meanwhile, growing awareness adverse impacts light at night on scientific astronomy, human health, ecological processes and aesthetic enjoyment sky has led to recognition pollution as significant global environmental issue. Links between economic activity, population growth are well documented in rapidly developing regions. Applying novel method analysis European lights over 15 years, we show that while continental trend is towards increasing brightness, some economically developed regions more complex patterns with large areas decreasing observed brightness this period. This highlights opportunities exist constrain even reduce impact delivering cost energy-saving benefits.
