  • Plenty of h2o in atmosphere, humans do not seem to affect the amount CO2 humans have a large affect on the amount in the atmosphere, disruption of the carbon cycle Also methane with increased rice production Nitrous oxide is also increasing due to fossil fuel emissions, however it’s amounts a small in comparison to co2
  • Transcript

    • 1. Global Climate I
    • 2. Goal 1 Explain the global greenhouse effect
    • 3. <ul><li>Greenhouse effect is in </li></ul><ul><li>NO WAY </li></ul><ul><li>related to the </li></ul><ul><li>Hole in the ozone layer !! </li></ul>
    • 4. <ul><li>Not related to </li></ul><ul><li>The </li></ul><ul><li>Hole in the ozone layer !! </li></ul>
    • 5. <ul><li>Has nothing to do with </li></ul><ul><li>The </li></ul><ul><li>Hole in the ozone layer !! </li></ul>
    • 6. <ul><li>Greenhouse effect </li></ul><ul><ul><li>Naturally occurring </li></ul></ul><ul><ul><li>Result of atmospheric gases </li></ul></ul><ul><ul><li>Not in dispute, it is a Scientific Law </li></ul></ul>
    • 7. <ul><li>Earth’s average temperature </li></ul><ul><li>without atmosphere </li></ul><ul><li>-18°C -0.4 </li></ul><ul><li>Earth’s average temperature </li></ul><ul><li>with atmosphere </li></ul><ul><li>15 °C 59°F </li></ul>
    • 8. <ul><li>Sun sends energy as visible light and near-visible infrared light waves </li></ul><ul><ul><li>Small wavelengths that can sneak past atmospheric molecules to reach Earth’s surface </li></ul></ul>
    • 9. <ul><li>Earth’s surface absorbs the energy sent by the sun and changes it to infrared energy (heat energy) </li></ul>
    • 10. <ul><li>The surface radiates infrared energy waves </li></ul><ul><ul><li>Longer wavelengths are absorbed by the atmospheric molecules and reemitted towards the surface (no escape) </li></ul></ul>

    • 13. <ul><li>Important gases in the atmosphere that act as greenhouse gases </li></ul><ul><ul><li>H 2 O (water vapor) </li></ul></ul><ul><ul><li>CO 2 </li></ul></ul><ul><ul><li>CH 4 (methane) </li></ul></ul><ul><ul><li>N 2 O </li></ul></ul>
    • 14. Goal 2 Describe the human impact on the carbon cycle
    • 15. <ul><li>Carbon cycle </li></ul><ul><ul><li>The cycle through which carbon is exchanged between the biosphere, geosphere, hydrosphere, and atmosphere </li></ul></ul>
    • 16. Image credit: PD: gov NASA
    • 17. <ul><li>Carbon pools: storage pools of carbon </li></ul><ul><ul><li>Sink if more carbon enters pool </li></ul></ul><ul><ul><ul><li>Plant growth </li></ul></ul></ul><ul><ul><ul><ul><li>Land </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Oceans </li></ul></ul></ul></ul>
    • 18. <ul><ul><li>Source if more carbon leaves pool </li></ul></ul><ul><ul><ul><li>Plant death </li></ul></ul></ul><ul><ul><ul><ul><li>Burning </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Decay </li></ul></ul></ul></ul><ul><ul><ul><li>Fossil fuel combustion* </li></ul></ul></ul>
    • 19. <ul><li>Human impact on carbon cycle </li></ul><ul><ul><li>Fossil fuels contain carbon </li></ul></ul><ul><ul><li>Fossil fuels in nature lock carbon away from carbon cycle </li></ul></ul><ul><ul><li>Human activity has unlocked this carbon </li></ul></ul><ul><ul><li>Added carbon to the carbon cycle </li></ul></ul>
