Globalwarming Globalwarming Presentation Transcript

  • GLOBAL WARMING
  • WHAT IS GLOBAL WARMING ?
  •  
  • CAUSES
    • GREEN HOUSE GASES
    • carbon dioxide
    • water vapor
    • methane
    • nitrous oxide
  • SOURCES OF GREEN HOUSE GASES
    • Thermal power plants, which burn the fossil fuels .
    • Road vehicles.
    • Industries.
  •  
  •  
  • EFFECTS OF GLOBAL WARMING
    • HIGH ATMOSPHERIC TEMPERATURES.
    • DISASTERS LIKE HURRICANES, DROUGHTS AND FLOODS.
    • DESTRUCTION OF OZONE LAYER.
    • MELTING OF POLAR ICE.
    • EXTINCT OF SOME ANIMALS DUE TO LOSS OF THEIR NATURAL HABITAT .

    • carbon sequestration
    • carbon dioxide air capture
    • Solar radiation management
    • stratospheric sulfur aerosols
    • cool roof techniques.
  • DO’S AND DONT’S
  • PLANT A PLANT
    • BENEFITS OF PANTING A TREE:
    • They help stop global warming by reducing greenhouse gases.
    • They reduce soil erosion and water pollution.
    • They provide habitat for native wildlife (including songbirds).
    • They improve human health by producing oxygen and improving air quality .
    • They reduce home energy needs by providing shade in summer and a windbreak in winter.
  • WHAT ONE TREE CAN DO FOR GLOBALWARMING
    • Absorbs over a ton of harmful greenhouse gases over its lifetime (U.S. Environmental Protection Agency).
    • Produces enough oxygen for four people every day (Tree Canada Foundation).
    • Provides the equivalent cooling effect of ten room-size air conditioners operating 20 hours a day (U.S. Department of Agriculture).
    • Provides an estimated $273 of environmental benefits in every year of its life (American Forests).
