Globalwarming

  1. 1. GLOBAL WARMING
  2. 2. WHAT IS GLOBAL WARMING ?
  3. 4. CAUSES <ul><li>GREEN HOUSE GASES </li></ul><ul><li>carbon dioxide </li></ul><ul><li>water vapor </li></ul><ul><li>methane </li></ul><ul><li>nitrous oxide </li></ul>
  4. 5. SOURCES OF GREEN HOUSE GASES <ul><li>Thermal power plants, which burn the fossil fuels . </li></ul><ul><li>Road vehicles. </li></ul><ul><li>Industries. </li></ul>
  5. 8. EFFECTS OF GLOBAL WARMING <ul><li>HIGH ATMOSPHERIC TEMPERATURES. </li></ul><ul><li>DISASTERS LIKE HURRICANES, DROUGHTS AND FLOODS. </li></ul><ul><li>DESTRUCTION OF OZONE LAYER. </li></ul><ul><li>MELTING OF POLAR ICE. </li></ul><ul><li>EXTINCT OF SOME ANIMALS DUE TO LOSS OF THEIR NATURAL HABITAT . </li></ul><ul><li>INTRODUCTION OF NEW DISEASES. </li></ul><ul><li>SHIFT IN SEASON CYCLE. </li></ul><ul><li>DESTRUCTION OF CROPS FOR SUDDEN CHANGES IN CLIMATE. </li></ul>
  6. 14. CLIMATE-ENGINEERING SUGGESTED
  7. 15. GEOENGINEERING TECHNIQUES <ul><li>greenhouse gas remediation </li></ul><ul><li>carbon sequestration </li></ul><ul><li>carbon dioxide air capture </li></ul><ul><li>Solar radiation management </li></ul><ul><li>stratospheric sulfur aerosols </li></ul><ul><li>cool roof techniques. </li></ul>
  8. 16. DO’S AND DONT’S
  9. 17. PLANT A PLANT <ul><li>BENEFITS OF PANTING A TREE: </li></ul><ul><li>They help stop global warming by reducing greenhouse gases. </li></ul><ul><li>They reduce soil erosion and water pollution. </li></ul><ul><li>They provide habitat for native wildlife (including songbirds). </li></ul><ul><li>They improve human health by producing oxygen and improving air quality . </li></ul><ul><li>They reduce home energy needs by providing shade in summer and a windbreak in winter. </li></ul>
  10. 18. WHAT ONE TREE CAN DO FOR GLOBALWARMING <ul><li>Absorbs over a ton of harmful greenhouse gases over its lifetime (U.S. Environmental Protection Agency). </li></ul><ul><li>Produces enough oxygen for four people every day (Tree Canada Foundation). </li></ul><ul><li>Provides the equivalent cooling effect of ten room-size air conditioners operating 20 hours a day (U.S. Department of Agriculture). </li></ul><ul><li>Provides an estimated $273 of environmental benefits in every year of its life (American Forests). </li></ul>
  11. 20. THANK YOU
