Global warming

  1. 1. Kai Hanae Kitazato haruka Global warming
  2. 2. Mechanism of Global Warming <ul><li>With the light from the sun's heat goes into the earth and it’s hit the ground. </li></ul>Usually… The sun’s heat is reflected. And it will be released into space. But…
  3. 3. Mechanism of Global Warming(2) <ul><li>After reflecting on the ground, the majority of solar </li></ul><ul><li>energy will be a further reflection by greenhouse gases. </li></ul>Back to the ground again. Most of the heat being emitted remain in the ground. As a result, the temperature rises.
  4. 4. Effects of Global Warming <ul><li>・ Climate change </li></ul><ul><li>・ Rising sea level </li></ul><ul><li> ‐ Glacier-melt </li></ul><ul><li>・ Increasing the unusual weather </li></ul><ul><li>‐ Flood, Drought, Hurricane etc... </li></ul><ul><li>・ Crisis of plants and animals </li></ul><ul><li>・ Heat Island </li></ul><ul><li>・ Infectious Disease </li></ul><ul><li>・ Problems of Food and Water </li></ul>
  5. 5. The present in global warming <ul><li>Rising sea level </li></ul><ul><li>  In a span of 20 century, </li></ul><ul><li>the sea level rose about </li></ul><ul><li>10~20cm.There are some </li></ul><ul><li>Islands may sink to the sea. </li></ul><ul><li>Tuvalu, Marshall Islands, Fiji, and so Islands are starting to be affected by encroachment of wave. </li></ul>
  6. 6. <ul><li>melting glacier </li></ul><ul><li>According to the satellite investigation of NASA, the large reduction of glaciers observed at the Andes, Himalayas, Alps and Pyrenees in the last 10 years. </li></ul><ul><li>     The   glacier of Himalaya s   is </li></ul><ul><li>retreating 10~15cm per year. </li></ul><ul><li>  </li></ul>
  7. 7. <ul><li>Forest fire </li></ul><ul><li>In 2003, the forest fire that be caused by fierce heat and drought started in all over the world. </li></ul><ul><li>The following is damage of forest fire in 2003. </li></ul><ul><li>・ Russia 23,710,000ha </li></ul><ul><li>・ America 2,888,738ha </li></ul><ul><li>・ Portugal 417,000ha </li></ul><ul><li>Besides this, France and Alaska has record forest fire. </li></ul>
  8. 8. Abnormal weather <ul><li>During the 20 century, the average temperature are rising about 0.6℃. </li></ul><ul><li>Global warming caused abnormal proliferation of typhoon and huge hurricane   in Asia. </li></ul><ul><li>In Bangladesh, the heavy rain and flood occurred often. </li></ul><ul><li>China and Australia was done drought damage. </li></ul><ul><li>A heat wave blow in Europe and Canada. </li></ul><ul><li>A cold wave blow in Europe and Central Asia. </li></ul>
  9. 9. Improvement plans ・ Introduce energy which saves energy or doesn’t discharge CO 2 (sunlight, wind, biomass, hydrogen, atomic energy, etc…) ・ Promote the economic activity which a small quantity of energy dependence. (energy-saving equipment, a low-emission vehicle, using means of public, etc...) ・ Accelerate the increase of carbon absorption quantity (tree planting, greening a desert, repress of felling forest, appropriate administration of irrigation and water resources, etc… )
