THE DAY AFTER TOMORROW : IMPACT OF GLOBAL WARMING ON SOCIETY

  1. 1. Global warming refers to a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
  2. 2. 1. Since 1971, 90% of the warming has occurred in the oceans. 2. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F). 3. Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850.
  3. 3.  Carbon dioxide emissions from fossil fuel burning power plants.  Carbon dioxide emissions from burning gasoline for transportation.  Methane emissions from animals, agriculture such as rice paddies, and from Arctic seabeds.  Deforestation , especially tropical forests for wood, pulp, and farmland.  Increase in usage of chemical fertilizers on croplands.
  4. 4. 1. Greenhouse is a glass house for keeping plants. 2. It absorbs heat but doesnot radiate it back to the atmosphere. 3. greenhouse gases plays the same role. 4. Global warming takes place when these greenhouse gases accumulate in the atmosphere which makes the average temperature on Earth warmer.
  5. 5.  CLIMATIC CHANGES  PHYSICAL IMPACTS  SOCIAL IMPACTS  Ecological changes
  6. 6.  Rise in temperature.  Increase in humidity .  Ueven distribution of rainfall.  Creation of lowpressure zone resulting in storms & cyclones.
  7. 7.  Floods & drought.  Inrease in sealevel.  Melting of glaciers & polar icecaps.  Submergence of islands & nearby coastal areas. Melting of polar icecaps
  8. 8.  Crop failure.  Water scarcity.  Migration & conflict for survival for all living beings including humans & cattle. Picture showing social effects of global warming
  9. 9.  Impact on biological systems.  Disturbance of foodchain & food web.  Increase of endangered species.  Extinction of species. Polarbears becoming endangerd
  10. 10. GRAPH SHOWING RISE IN CARBONDIOXIDE EMISSIONS & RISE IN TEMPERATURE
  11. 11. Global warming has many adverse effects , so it can be controlled in the following way :- Afforestation. Avoid burning of fossil fuels. Use alterative sources of energy like wind , tidal etc .
