Climate change and global warming by Lauren and Kerry

  1. 1. Climate Change and Global Warming<br />By Kerry and Lauren <br />
  2. 2. Green House Effect- The heating of Earth’s surface and atmosphere from solar radiation being absorbed and emitted by the atmosphere mainly by water vapor and carbon dioxide <br />Global Warming- The increase in average temperatures of Earth and the atmosphere due in part to increased carbon dioxide levels <br />Climate Change- The overall transformation of Earth’s climate over a long period of time, due to plate tectonics, Earth’s orbital motions, solar activity, and volcanic eruptions<br />Definitions<br />
  3. 3. The fossil fuels we are burning contribute to higher concentrations of methane, carbon dioxide, and nitrous dioxide. These gases are called greenhouse gases. They create a thick blanket around our globe and trap lots of heat, causing global warming. This turns the Earth into something like a greenhouse. <br />*Not that it is important to remember both that the greenhouse effects occurs naturally, but that it has been a bigger issue because of mankind’s emissions of greenhouse gases into the atmosphere<br />Connecting It All Together<br />
  4. 4. <ul><li>Green house gases are the main cause.
  5. 5. Research from the past and present shows that carbon dioxide levels have increased tremendously due to the emission of more carbon dioxide levels
  6. 6. Emissions come from coal and oil that we burn for energy
  7. 7. Humans are the main cause for global warming</li></ul>Causes of Global Warming<br />
  8. 8. Consequences<br /><ul><li>Threats to People and Health
  9. 9. Very strong heat waves
  10. 10. Spread of disease
  11. 11. Worsening air quality
  12. 12. Extreme/ more dangerous weather
  13. 13. More wildfires and flooding
  14. 14. Draught
  15. 15. Stronger Hurricanes
  16. 16. Thinning Ice/ Rising Seas
  17. 17. Arctic ice is shrinking
  18. 18. Rise in sea level
  19. 19. Glaciers melting
  20. 20. Biodiversity Loss
  21. 21. Decrease in Polar Bear population
  22. 22. Acidifying Oceans
  23. 23. Coral Bleaching
  24. 24. Moving habitats
  25. 25. Threats to Western Forests</li></li></ul><li><ul><li> If there are food shortages due to dying crops from the rising temperature, price of food will raise and more will go without
  26. 26. Some governments, like ours, our trying to go “Green” but they don’t know how much it is going to cost
  27. 27. It could be worse to do nothing in which the economy could fail us completely </li></ul>Impacts on Economy<br />
  28. 28. <ul><li>Write letters to local government asking for a more eco-friendly town
  29. 29. Replace regular light bulbs with fluorescent lights
  30. 30. Unplug unused appliances
  31. 31. Recycle and Reuse
  32. 32. Cut back on Paper
  33. 33. Educate yourself and others
  34. 34. Plant Trees
  35. 35. Carpool</li></ul>Fighting Back<br />
  36. 36. <ul><li> Some scientists believe that human activities don’t disrupt Earth’s climate
  37. 37. Some say our most reliable sources do not show a trend of global warming since they began taking readings 23 years ago
  38. 38. All predictions are based on computer models, not real life. Some think this does not give an accurate reading
  39. 39. Some think a small amount of global warming could benefit the Earth and civilization as a whole.
  40. 40. It would be extremely expensive to quickly fix global warming and would not be very effective</li></ul>Arguments <br />
  41. 41. <ul><li>We believe that global warming is a serious issue and does need to be addressed.
  42. 42. The reason for this is due to the serve consequences that we will and already are facing. For example, the poles are shrinking, sending huge chunks of melting ice into the oceans. Arctic animals like the polar bears are dying out because this change. Coral Reefs are being bleached and drained of their color
  43. 43. Also, raising temperatures are causing crops to wither and die, depleting the food storage of the world. If it got too bad we may face food shortages and more hunger</li></ul>Personal Opinion<br />
