  1. Global Environmental Trends: Global Commons World Resources Institute http://www.wri.org/wri/

  2. Vehicle numbers are rising dramatically

  3. Motor vehicle use is highest in developed countries

  4. Temperature (Fahrenheit) Temperature (Celcius) 60 59.5 59 58.5 58 57.5 154 152 150 148 146 144 142 1860 1880 1900 1920 1940 1960 1980 2000 Surface temperatures have warmed over the past century

  5. Greenhouse gas warming

  6. Per capita CO2 emissions are small in developing countries (metric tons of carbon dioxide)

  7. Developed nations have altered the atmosphere most

  8. Stabilizing CO2 means steep emission cuts eventually

  9. Success story: CFC production has fallen sharply

  10. Backsliding: Halon production is rising again

  11. Excess nutrients may spur algal blooms Pre 1972

  12. Excess nutrients may spur algal blooms Post 1972

  13. More fertilizer: More food, but more pollution too

  14. SO2 emissions in Asia could triple

  15. NOx levels are still a problem in Europe and North America
