Night shift

Increased sightings of noctilucent or night-shining clouds are thought to be due to cooling temperatures in the upper 'mesopause' region of the atmosphere and increasing amounts of water vapour. Since the late 1960s, the appearance of noctilucent clouds has increased. Researchers are investigating a possible link between noctilucent clouds and climate change.
