Atmosphere of Earth development of animals. Today's atmosphere contains 21% oxygen, which is great enough for this rapid development of animals. "Air pollution" is the introduction into the atmosphere of chemicals, particulate matter or biological materials that cause harm or discomfort to organisms. Stratospheric ozone depletion is caused by air pollution, chiefly from chlorofluorocarbons and other ozone-depleting substances. The scientific consensus is that the anthropogenic greenhouse gases currently accumulating in the atmosphere are the main cause of global warming. On October 19, 2015 NASA started a website containing daily images of the full sunlit side of Earth on http://epic.gsfc.nasa.gov/. The images are taken
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
