Global Warming

  1. 1.   Kai Hanae Kitazato haruka
  2. 2. Mechanism of Global Warming With the light from the sun's heat goes into the earth and it’s hit the ground. Usually… The sun’s heat is reflected. And it will be released into space. But…
  3. 3. Mechanism of Global Warming(2) After reflecting on the ground, the majority of solar energy will be a further reflection by greenhouse   gases. 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 ・ Climate change ・ Rising sea level  ‐ Glacier-melt ・ Increasing the unusual weather ‐ Flood, Drought, Hurricane etc... ・ Crisis of plants and animals ・ Heat Island ・ Infectious Disease ・ Problems of Food and Water
  5. 5. The present in global warming Rising sea level   In a span of 20 century, the sea level rose about 10~20cm.There are some Islands may sink to the sea. Tuvalu, Marshall Islands, Fiji, and so Islands are starting to be affected by encroachment of wave.
  6. 6. melting glacier 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.   The   glacier of Himalaya s is retreating 10~15cm per year.
  7. 7. Forest fire In 2003, the forest fire that be caused by fierce heat and drought started in all over the world. The following is damage of forest fire in 2003. ・ Russia 23,710,000ha ・ America 2,888,738ha ・ Portugal 417,000ha Besides this, France and Alaska has record forest fire.
  8. 8. Abnormal weather During the 20 century, the average temperature are rising about 0.6 .℃ Global warming caused abnormal proliferation of typhoon and huge hurricane   in Asia. In Bangladesh, the heavy rain and flood occurred often. China and Australia was done drought damage. A heat wave blow in Europe and Canada. A cold wave blow in Europe and Central Asia.
  9. 9. Improvement plans ・ Introduce energy which saves energy or doesn’t discharge CO2 (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… )
