Nouveau présentation microsoft power point (1)

  1. 1. Greenhouse effect Presented by : SOUAHIA Rabiaa Master EFTIS FADESP-A M1
  2. 2. Plan <ul><li>History of Greenhouse effect. </li></ul><ul><li>Definition and mechanism of Greenhouse effect. </li></ul><ul><li>Causes of Greenhouse effect. </li></ul><ul><li>Consequences of Greenhouse effect. </li></ul><ul><li>Wayes to redue the Greenhouse effect. </li></ul><ul><li>Conclusion. </li></ul>
  3. 3. History of Greenhouse effect <ul><li>Svant Arrhenius (1859-1927) Swedich scientist. </li></ul><ul><li>1896: He was the first to claim that fossil fuel combustion may eventually result in enhanced global warming. </li></ul><ul><li>He found that the average surface temperature of the earth is about 15°c because of the infrared absorption capacity of water vapor and carbon dioxide. </li></ul><ul><li>He suggesed a doubling of the carbon dioxide concentration would lead to a 5°c temperature rise. </li></ul>
  4. 4. Definition and mechanism of Greenhouse efffect
  5. 5. Causes of Greenhouse effect <ul><li>The main reason for Greenhouse effect is the emission of gases like nitrous-ioxide, carbon dioxide, methane, ozone and water vapor . The causes of these emissions have been listed below. </li></ul>
  6. 6. Causes of Greenhouse effect Deforestation Burning of fossiel fuels Electrical appliances Industries Automobiles Population growth
  7. 7. Consequences of Greenhouse effect <ul><li>Rise of the level of the seas . </li></ul><ul><li>Climatic altertions in all the planet. </li></ul><ul><li>Increase of the terrestrial and oceanic biomass. </li></ul><ul><li>Deep modifications in the typical vegetation of each region and altitude. </li></ul><ul><li>Increase in the incidence of illnesses and proliferation </li></ul>
  8. 8. Wayes to reduce Greenhouse effect <ul><li>Reduce, reuse, recycle. </li></ul><ul><li>Use less heat and air conditioning </li></ul><ul><li>Replace your light bulbs </li></ul><ul><li>Buy energy-efficient products </li></ul>
  9. 9. Wayes to reduce Greenhouse effect <ul><li>Use less hot water </li></ul><ul><li>Use the « off » switch </li></ul><ul><li>Plant trees </li></ul><ul><li>Encourage others to conserve energy </li></ul><ul><li>Drive less drive smart </li></ul>
  10. 10. Conclusion <ul><li>From 1998 onwards the terminology on the Greenhouse effect started to change as a result of media influences. The Greenhouse effect as a term was used less and less and people started to refer to the theory as either global warming or climate change. </li></ul>
