  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>Most of the heat being emitted remain in the ground. As a result, the temperature rises. Back to the ground again.
  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>  </li></ul><ul><li>The   glacier of Himalaya s is </li></ul><ul><li>retreating 10~15cm per year. </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>

  9. 9. Improvement plans <ul><li>・ Introduce energy which saves energy or doesn’t </li></ul><ul><li>discharge CO 2 (sunlight, wind, biomass, hydrogen, </li></ul><ul><li>atomic energy, etc…) </li></ul><ul><li>・ Promote the economic activity which a small quantity </li></ul><ul><li>of energy dependence. (energy-saving equipment, a </li></ul><ul><li>low-emission vehicle, using means of public, etc...) </li></ul><ul><li>・ Accelerate the increase of carbon absorption quantity </li></ul><ul><li>(tree planting, greening a desert, repress of felling </li></ul><ul><li>forest, appropriate administration of irrigation and </li></ul><ul><li>water resources, etc… ) </li></ul>
