Global Warming

  1. 1. Global Warming
  2. 2. What is Global Warming?
  3. 3. How Global Warming Works Carbon Dioxide (CO2) Fossil fuels (coal, oil, natural gas)
  4. 4. Earth’s Atmospheric Gases Nitrogen (N2) Oxygen (O2) NonGreenhouse Gases 99% Water (H2O) Carbon Dioxide (CO2) Methane (CH4) Greenhouse Gases 1%
  5. 5. Greenhouse Gases The gases responsible for the greenhouse effect are  CH4  NO2  H2O And many more. These gases are the major cause of Global Warming
  6. 6. Working of Greenhouse Gases
  7. 7. Source of Greenhouse Gases Pollution from coal, natural gas, and oil
  8. 8. Consequences of Global Warming Rising Sea Level Habitat Damage and Species Affected Increased Temperature Changes in Water Supply
  9. 9. The severity of Global Warming on the Earth Global warming has very severe effects on the Earth like • Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. • Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years. • Sea level rise became faster over the last century. • Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas. • Precipitation (rain and snowfall) has increased across the globe, on average.

  12. 12. Global Warming: Shifting Gears
  13. 13. Billions of Metric Tons Carbon Goal: Reductions in 2007 CO2 Per Year
  14. 14. Billions of Metric Tons Carbon Gigaton Carbon Our Goal 2007 Reductions in CO2 Per Year Produce electricity efficiently Use electricity efficiently Vehicle efficiency Solar and Wind Power Biofuels Carbon capture and storage
  15. 15.  The Planet is in serious trouble
  16. 16. What can you do to help solve the problem?
  17. 17. What should we do… Nothing Something Everything
  18. 18. What’s being done now to reduce our emissions? Wind Power Solar Power Fuel-Efficiency
  19. 19. Simple Things You Can Do Turn off your computer or the TV when you’re not using it. Take shorter showers. Heating water uses energy. Keep rooms cool by closing the blinds, shades, or curtains. Turn off the lights when you leave a room. Use compact fluorescent bulbs.
  20. 20. Simple Things You Can Do Dress lightly when it’s hot instead of turning up the air conditioning. Or use a fan. Dress warmly when it’s cold instead of Turning up the heat. Offer to help your parents keep the air filters on your AC and furnace clean. Walk short distances instead of asking for a ride in the car. Recycle. Plant a tree.
  21. 21. Despair? You may never know what results come of your action, but if you do nothing, there will be no result.
