Global warming effects and control measures

  1. 1. Presented By: Deepak Kumar Environmental Science C.C.S. University Meerut Email id: deepak.environment2009@gmail.com
  2. 2.  Gradual rise in atmosphere & ground surface or lower atmosphere temperature ie. Troposphere & consequent change in global radiation balance.  As a result of enhanced greenhouse effect increase in the mean temperature of earth’s lower atmosphere.
  3. 3. incoming outgoing
  4. 4. 78% nitrogen 20.6% oxygen < 1% argon 0.4% water vapor 0.036% carbon dioxide traces gases: Ne, He, Kr, H, O3 Methane, Nitrous Oxide Composition of Atmosphere
  5. 5.  Carbon Dioxide (387PPM)     Methane (1750 PPb)     Source: Fossil fuel burning, deforestation Anthropogenic increase: 30% Average atmospheric residence time: 500 years Source: Rice cultivation, cattle & sheep ranching, decay from landfills, mining Anthropogenic increase: 145% Average atmospheric residence time: 7-10 years Nitrous oxide (320 PPb)    Source: Industry and agriculture (fertilizers) Anthropogenic increase: 15% Average atmospheric residence time: 140-190 years
  6. 6.     CFC’s (Chloroflouro carbons 290 PPt) Sources: Refrigeration units, Air-conditioning, aerosol spray cans, solvent etc. Anthropogenic increase 4%/year Residence time 22-102 years
  7. 7. Contribution of GHG's to Global Warming(%) 6% 14% CO2 CH4 CFC's 20% 60% N2O
  8. 8. Relative Contribution of Human activities in Global Warming 13% 14% 49% 24% Burning of fossils fuel Industrial process Deforestation Agriculture
  9. 9.      Elevated Temperature of Biosphere - Melting of Polar Ice Cap - Rise in Sea level Climate Change - Changing weather Pattern - High precipitation during shorter period Ecosystem Destruction - Coral bleaching etc. Crop Yield Human Health
  10. 10. Effects
  11. 11. Effects Rainfall in Mumbai (India) 2005 1 million people lost their homes
  12. 12. Effects  Regions where major coral reef bleaching events have taken place during the past 15 years Yellow spots indicate major bleaching events
  13. 13. Effects Effects of Hurricane Katrina 2005 in USA
  14. 14.  Alternative source of energy  Generation of Carbon Sink  Carbon Trading  Imposing Carbon Tax
  15. 15. UNFCC (United Nations Framework Convention on Climate Change) Stabilize atmospheric concentration of GHG’s at a level that would prevent dangerous anthropogenic interference with climate system. Kyoto Protocol (Japan) It is an agreement for the reduction of GHG’s and CFC’s emissions by the nations.
  16. 16.    Increasing human population play important role to increasing levels of GHG’s emission. Increasing concentration of GHG’s gases may lead to more severe catastrophes than earlier. Today’s demand to take action to reduce the emission of GHG’s at the global level. If it couldn't implemented, it will be a question for forever Is life exist in future?
