  1. THEMATIC SLIDES

  2. ATMOSPHERE Nightlight Map of the World

  3. Thinning of the Ozone Layer Evidence from satellites of thinning of the Ozone layer led to the Montreal Protocol for reducing CFCs

  4. Ozone Hole 1999 1979 1990 1988 1982 1992 1997 1986 1984 1994 Darkest blue areas represent regions of maximum ozone depletion 2004

  5. Increase of atmospheric carbon dioxide 2000-about 365 ppm Carbon dioxide levels have risen by 30% in the last 200 years. The IPCC projects that, if unchecked, atmospheric carbon dioxide concentrations will range from 650 to 970 ppm by 2100.

  6. Movement of transboundary pollutants A large dust storm developed in East Asia on 6-7 April 2001, moving over Russia, Japan, the Pacific Ocean, Canada, and ultimately over the United States on 17 April 2001

  7. Air pollution due to wild fires Wild fires in Africa are a major source of air pollution Tens of thousands of fires are detected every year

  8. Retreating Gangotri glacier Receding glacier tracked since 1780 In the last 25 years, Gangotri Glacier has retreated more than 850m (2 788 ft)
