    • GLOBAL WARMING
    • CAUSES
      • Extensive use of fossil fuels.
      • Increase in green house gases released into the
      • atmosphere.
      • .deforestation decreases the conversion of
      • Co2 to o2
    •  
    • Use of fossil fuels
      • Increases the carbon composition in the atmosphere.
      • increases the amount of carbonic acid formed in the ocean that increases the Ph level of the sea water.
    •  
    • Green house gases
      • These gases like co2,methane,nitrous oxide are responsible for trapping more infrared radiation from the sun thus increasing the global temperature levels .
      • This heat is absorbed by the oceans.
    •  
    • WHAT HAPPENS NEXT? .INCREASE IN OCEAN TEMPERATURE ALTERS THE NORMAL WEATHER PATTERNS OF OUR EARTH . .MELTING OF ICE CAPS INCREASES THE SEALEVEL. .THE ICE CAPS IN POLES,GLACIERS ANDOTER AREAS WHERE ICE HAS BEEN BUILDING FOR SEVERAL 1000S OF IS MELTINS.
    • Melting of ice
      • It happening right now
    • Larsen-b ice shelf.
    •  
    • Seward in alaska
    • A vanished glacier in greenland.
    • Mount .ubinas in peru.
    • Change in weather patterns . Increase in ocean temperature alters the normal The normal weather patterns that our earth had Sustained after the last ice age. .causing cyclones of huge intensity.
    • Killer katrina
    • Hurricanes in the southernhemishere
    • Sea level rising
      • rising at an average rate of 1 - 2 mm/year over the past 100 years
    •  
    • Population displacement
      • Rising sea levels
      • Increase the risk of coastal flooding
      • (Necessitate population displacement)
      • More than half of the world's population now lives within 60km of the sea.
      • Most vulnerable regions: Nile delta in Egypt, the Ganges-Brahmaputra delta in Bangladesh, many small islands, such as the Maldives, the Marshall Islands and Tuvalu.
    • Direct Temperature Effects
      • Increase in average temperature
      • More extreme heat waves during the summer; Less extreme cold spells during the winter
      • Harmful to those with heart problems, asthma, the elderly, the very young and the homeless
    • Measures on controlling the problem
      • Governments
      • * set some laws to limit the amount of pollutants produced by factories
      • * develop the skills of using renewable fuels , e.g. solar energy, wind energy
    • Measures on controlling the problem
      • Citizens
      • * reduce the use of plastic bags -> as burning plastic emit CH4
      • * recycle the resources, e.g. plastic
      • * reduce the use of sprays -> as CFCs would be emitted out
    • THE END.
