Climate Change: Understanding the Impact and Taking Action

This presentation provides valuable information about climate change and its consequences for our planet. It discusses the significant rise in carbon dioxide levels, temperature projections for the 21st century, melting ice caps, and the potential increase in extreme weather conditions. The presentation highlights the importance of taking action to mitigate these effects and offers resources for further learning.

Presentation Transcript

  1. Climate Change (and You) Mark van Soestbergen ICBE UF BCN January 9, 2007

  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

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

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

  7. Greenland is melting NY Times June 8, 2004

  8. 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.

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

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

  12. 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
