Global Warming: Fact or Fiction?

1. Global Warming:Fact or Fiction? Presented By: Kenyatta Esters Rhonda Nichols

2. What is Global Warming? • Refers to a general warming trend of the earth • Possible causes: • Tectonic • Astronomical • Green house gasses • Other Atmospheric conditions

3. 1880-2000 1950-2000 Earths Temperature Fluctuation

5. Green House Gasses Carbon Dioxide 50% Methane 18% 27x CO2 Nitrous Oxide 6% 150xCO2 Synthetic Gasses (CFC’s) and other 26% 6% CFC10,000x CO2 CFC substitutes 300-5,000xCO2

6. “Careful measurements have confirmed that CO2 is increasing in the atmosphere and that human activities are the primary cause… • … 31% increases can not be explained by natural causes. CO2 concentrations are now likely higher than any seen in the in at least 420,000” • EPA Website

7. Green House Gas

8. Impacts • Flooding of Coastal Areas • Salt Water Encroachment

9. Impacts • Flooding of Coastal Areas • Major cities • New OrleansNew Atlantis, Miami, Bancock, Netherlands • Marsh • Everglades disappearance • Salt Water Encroachment

10. Calculate the effect of melting glaciers on sea level • Total Surface Area of Earth • 197,000 sq miles • 70% ocean 138,000 sq miles • 30% land59,000 sq miles • 326 million miles3 total water • Oceans 317 million • Glaciers 7 million • Water volume increase • 2 million km29 million

11. Is Global Warming Real??? Is it a DIRECT consequence of fossil fuel use? Do we have an ethical obligation to reduce CO2 emissions?

12. Little things mean a lot • Drive less/fly less • Heat less • Renewable Energies • Buy locally produced fuels • Recycle • Energy efficient transportation and buildings • Educate others • Encourage protection of natural resources • Question Everything • Political/Corporate/Academic/Environmental Stances
