  1. Climate Change (and You) Mark van Soestbergen ICBE UF BCNSeptember 1, 2005

  2. Carbon Dioxide Intercepts infrared waves going into space

  3. Gasoline is 85.5% carbon 1 gallon of conventional gasoline becomes172 cubic feet / 4.87 cubic meters of CO2

  4. Humans add about 25 billion tonne carbon dioxideto the atmosphere each year

  6. Globally, temperatures are projected to rise an additional 2 – 5°C in the 21st Century We are here

  7. Summer Arctic Sea Ice 1979 2000 NASA Goddard Space Flight Center

  8. Greenland is melting NY Times June 8, 2004

  9. Currents distribute heat

  13. Sea Surface Temp Anomaly, Jun~Sep, 2003

  14. The oceans have absorbed about 30 times more heat than the atmosphere since 1955

  15. Global Climate Changechanges everything • CO2 changes plant behavior • Increases temperature of the atmosphere,the earth’s crust and the oceans • Affects global hydro cycle

  16. Summers will be scorchers These maps show the projected increase in average daily July heat index relative to the present. The largest increases are in the southeastern states, where the models projects increases of more than 25°F. A July day in Atlanta that now reaches 105°F would reach 115°F in the Hadley model, and 130°F in the Canadian model.

  17. Florida • Reversal of summer-wet, winter-dry • Brand new animal, plant and human diseases • Sea level rise • Storms

  18. Expected sea level increase 21st Century: + 1.2 meter Florida + 5 meter, unavoidable w/out action Courtesy: PBS

  19. The atmosphere now holds 30% more carbon than a century ago. Humanemission rate in billiontC/yr 8 equilibrium Earth absorption ratein billiontC/yr 4.7 de-carbonization pathway time Latent atmospheric Carbon isabout 188 billion ton

  20. U.S. commitment under Kyoto
