Global Atmosphere Watch was mere scientific interest, but of course, many scientists eventually wondered what effects these trace chemicals could have on the atmosphere, and on life. The GAW's genesis began as far back as the 1950s when the World Meteorological Organization began a programme of monitoring the atmosphere for trace chemicals, and also researching air pollution from a meteorological point of view. They were also responsible for monitoring ozone, establishing the Global Ozone Observing System (GO3OS) in 1957, in the International Geophysical Year. In 1968, the United Nations called for an international conference to address world environmental problems caused by rapid industrialization.
Atmosphere of Pluto data shows that the pressure continues to increase. An occultation of an exceptionally bright star, about 10 times brighter than Pluto itself, was observed on 29/30 June 2015 – only 2 weeks before the "New Horizons" encounter. On 14 July 2015 the "New Horizons" spacecraft made the first explorations of the atmosphere of Pluto from close distance, including radio occultation measurements and observations of weakening of solar radiation during flight through Pluto's shadow. It provided the first direct measurements of parameters of the lower atmosphere. The surface pressure turned out to be . Atmosphere of Pluto The atmosphere of Pluto
