  2. 2. Global warmingWhat is it ? The solar laser come on to the surface of earth and some return to upward and laser are clash with Green house layer but Co2 absorb it and back to Earth . When the so many laser are back to the Earth, They can heat the Earth. Therefore, the thaw the snow and increase sea surface with many kind of problems
  3. 3. What Causes Global Warming?Greenhouse Gases Carbon Dioxide +0.9 K Methane +0.27 K Other greenhouse gases +0.4 KWarming particles Fossil-fuel soot +0.3 KHeat island < +0.1 K
  4. 4. Effect on Environment

  9. 9. Nuclear power for global warmingForeign Correspondents’ Club ofJapanMay 29, 2008The nuclear industry, supported bysome governments, has seized onglobal warming as an opportunity topromote nuclear energy as a Co2-freesolution to global warming.
  10. 10. Generation of electricity by nuclearpower plants is not a viableresponse to this crisis.There are only two potential ways thatnuclear power could tackle globalwarming:By using current nuclear power plantsalready online.By building and using new nuclear powerplants.
  11. 11. Today435 nuclear plants worldwide.
  12. 12. By 2025Half of today’s plants will be too old to operate.* (assuming 40-year lifespan)
  13. 13. In reality, total operating capacity will decrease,not increaseUsing current nuclear power plants tofight global warming would require animpossible increase in utilized capacity.
  14. 14. Nuclear Power in Japan Japan Target of 88%* Average: 74% * Set by Japan Ministry of Economy, Trade and Industry
  15. 15. Nuclear Power in Japan ity” ca pac . ized ealistic Japan Target of 88%* util unr “ 88% et is targ plant Reduction in safety, stability. * Set by Japan Ministry of Economy, Trade and Industry
  16. 16. Nuclear power is unreliable for fighting global warming. Scandals, earthquakes and accidents can shut down numerous plants simultaneously.Nuclear power — too costly to matter New nuclear power is so costly that shifting a dollar/euro from nuclear to efficiency protects the climate four to seven times more than shifting a dollar/euro of spending from coal to nuclear.*Nuclear power will make global warming worse.
  17. 17. Nuclear power is NOT the answer toglobal warming.ANSWER:Reducing energy demand thoughconservation and efficiencyMicro power renewables
