Transcript

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