    Greenhouse gases Greenhouse gases Presentation Transcript

    • Atmospheric Chemistry!
      Greenhouse Gases
    • Gases which capture the heat from the atmosphere.
      What are greenhouse gases??
    • statistics…
      consistently keep the earth 33 degrees Celsius (91.4 degrees F) warmer than in normally would be
      the global temperature has risen .5 degrees Celsius in the past century
      Temperatures
      Result
    • ~natural causes~
      Volcanoes
    • Eyjafjallajokull-
      2010 Iceland Volcano
    • Eyjafjallajokull
      EYE-a-fyat-la-jo-kutl
      erupted 2010
      smoke cloud reached 11,000- 20,000 feet
      the ash cloud was 5-6 miles in the air
      gases contain sulphuric aerosols
      over 112 million tons of sulphur dioxide were emitted in 8 months
    • Sulphur Dioxide
      SO2
      colorless
      distinct smell
      irritates skin, eyes, nose, and mouth
      harms lungs
    • Greenhouse gas emissions…
      24 billion tons of carbon dioxide from cars, and industries combined. (world wide)
      200 million tons of carbon dioxide per year (land and sea)
      Humans
      Volcanoes
    • what’s in greenhouse gases??
      No natural sources (worst destroyer
      of the ozone) (CFC’S)
      (chlorofluorocarbons)
      mainly human made
      used in soils, and
      agriculture
      Gasoline, coal,
      oil, natural gas,
      in combustion
      reactions
      mostly comes from nature
      it’s a natural gas
      The quickening of the
      destruction of
      rain forests
