What is global warming l.jpg
What is Global Warming?

  • Refers to a general warming trend of the earth

  • Possible causes:

    • Tectonic

    • Astronomical

    • Green house gasses

    • Other Atmospheric conditions

1880-2000

1950-2000

Earths Temperature Fluctuation


Green house gasses l.jpg
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

  • “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


  • Green house gas l.jpg
    Green House Gas increasing in the atmosphere and that human activities are the primary cause…


    Slide8 l.jpg

    Impacts increasing in the atmosphere and that human activities are the primary cause…

    • Flooding of Coastal Areas

    • Salt Water Encroachment


    Impacts l.jpg
    Impacts increasing in the atmosphere and that human activities are the primary cause…

    • Flooding of Coastal Areas

      • Major cities

        • New OrleansNew Atlantis, Miami, Bancock, Netherlands

      • Marsh

        • Everglades disappearance

    • Salt Water Encroachment


    Calculate the effect of melting glaciers on sea level l.jpg
    Calculate the effect of melting glaciers on sea level increasing in the atmosphere and that human activities are the primary cause…

    • 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


    Slide11 l.jpg

    Is Global Warming increasing in the atmosphere and that human activities are the primary cause…Real???

    Is it a DIRECT consequence of fossil fuel use?

    Do we have an ethical obligation to reduce CO2 emissions?


    Little things mean a lot l.jpg
    Little things mean a lot increasing in the atmosphere and that human activities are the primary cause…

    • 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
