Global Warming

  1. 2. the INCONVENIENT TRUTH and the CONSEQUENCES GLOBAL WARMING
  2. 3. The Truth… <ul><li>If the ice caps keep melting at their current rate, parts of the Atlantic and Gulf coasts in the United States will be submerged underwater by 2100. </li></ul>
  3. 4. What is Global Warming? Sun’s energy The earth radiates some energy Greenhouse gases traps energy
  4. 5. <ul><li>Sun’s energy heats up the earth’ surface, affecting its weather. </li></ul><ul><li>The earth radiates some energy back into space to moderate the planet’s temperature. </li></ul><ul><li>But as industry booms on earth greenhouse gases are released into the air and trap more and more of the sun’s energy in, so the earth’s temperature rises. </li></ul>
  5. 6. Greenhouse Gases <ul><li>Carbon Dioxide </li></ul><ul><li>Methane </li></ul><ul><li>Nitrous Oxide </li></ul>
  6. 7. Carbon Dioxide from: <ul><li>Power plants </li></ul><ul><li>Cars </li></ul><ul><li>Trucks </li></ul><ul><li>Airplanes </li></ul><ul><li>Buildings </li></ul>
  7. 8. Methane <ul><li>More than 20 times as effective as Carbon Dioxide in trapping heat in the atmosphere </li></ul><ul><li>Sources </li></ul><ul><ul><li>Rice paddies </li></ul></ul><ul><ul><li>Bovine flatulence </li></ul></ul><ul><ul><li>Bacteria in bogs </li></ul></ul><ul><ul><li>Fossil fuel production </li></ul></ul>
  8. 9. Nitrous Oxide <ul><li>“ laughing gas”, used as an anaesthetic </li></ul><ul><li>Man made sources are nylon and nitric acid production, fertilizers </li></ul>
  9. 10. Causes of Global Warming <ul><li>Carbon dioxide emission by humans </li></ul><ul><li>Deforestation </li></ul><ul><li>City gridlock </li></ul>
  10. 11. Consequences <ul><li>Warmer temperatures </li></ul><ul><li>Drought and wildfire </li></ul><ul><li>More intense rainstorms </li></ul><ul><li>Deadly heat waves and the spread of disease </li></ul><ul><li>More powerful and dangerous hurricanes </li></ul><ul><li>Melting glaciers </li></ul><ul><li>Sea level rise </li></ul><ul><li>Ecosystem shifts and species die-off </li></ul>
  11. 12. Warmer Temperatures <ul><li>Average temperatures will rise, as will the frequency of heat waves. </li></ul>
  12. 13. Drought and Wildfire <ul><li>Greater evaporation particularly during summer could exacerbate drought conditions and increase the risk of wildfires. </li></ul>
  13. 14. More intense rainstorms <ul><li>Warmer temperatures increase the energy of the climatic system and lead to more intense rainfall at some times and in some areas. </li></ul>
  14. 15. Deadly heat waves and the spread of disease <ul><li>Global warming is expected to increase the virulence of tropical diseases as well. </li></ul>
  15. 16. More powerful and dangerous hurricanes <ul><li>Warmer water in the ocean pumps more energy into tropical storms, making them more intense and potentially more destructive. </li></ul>
  16. 17. Melting glaciers <ul><li>Rising global temperatures will spread the melting of glaciers and ice caps, and cause early ice thaw on rivers and lakes. </li></ul>
  17. 18. Sea level rise <ul><li>As a result both of thermal expansion of the oceans and melting glaciers. </li></ul><ul><li>Loss of coastal wetlands and barrier islands and flooding in coastal communities. </li></ul>
  18. 19. Ecosystem shifts and species die off <ul><li>Loss of species diversity as species that cannot adapt die off </li></ul><ul><li>Some ecosystems like mangrove forests are likely to disappear due to new warmer local climates or coastal sea level rise will not support them. </li></ul>
  19. 20. STOP GLOBAL WARMING! <ul><li>1. Calculate your carbon </li></ul><ul><li>2. Unplug your gadgets </li></ul><ul><li>3. Use less water </li></ul><ul><li>4. Walk to school </li></ul><ul><li>5. Recycle your stuff </li></ul><ul><li>6. Try fluorescent bulbs </li></ul><ul><li>7. Buy in bulk </li></ul>
  20. 21. <ul><li>8. Plant a tree </li></ul><ul><li>9. Get political </li></ul><ul><li>10. See an inconvenient truth </li></ul>
  21. 22. Reducing garbage <ul><li>Switch from disposable to reusable products </li></ul><ul><li>Replace paper products </li></ul><ul><li>Avoid buying single use and small size products </li></ul>
  22. 23. Saving Trees <ul><li>Save old term paper and hand outs </li></ul><ul><li>Create and use note pads </li></ul><ul><li>Use email instead of sending cards </li></ul><ul><li>Don’t accept unwanted mail </li></ul><ul><li>Better yet PLANT MORE TREES! </li></ul>
