We made this presentation to impress our geography teacher Ms. Renuka Kaushik and she was speechless when she saw it. This is mainy for bringing a realistic touch to this topic and not just theory. Took a week to make, choosing and editing the best information. hope you like it:):)

Global Warming

  1. 1. What is Global Warming ?• Global Warming is the rise in average temperature of the Earth due to man – made activities like deforestation , combustion of fossil fuels etc.• Since the early 20th century, Earths average surface temperature has increased by about 0.8 °C with about two-thirds of the increase occurring since 1980.
  2. 2. Global Warming !!!Global Warming StatisticsTotal amount of carbon dioxide that is released into 31 billionthe worlds atmosphere everyday tonsTotal amount the sea level has risen in the past 100 17.5cmyears
  3. 3. • Greenhouse gas emissions by source sector
  4. 4. This graph shows how we depend the maximum onfossil fuels for our energy needs
  5. 5. The prediction of the temperature increase onEarth due to Global Warming by 2070 - 2100
  6. 6. Different vehicles that emit Carbon dioxide
  7. 7. Some of the greenhouse gases• Carbon Dioxide (CO2)- Source: Fossil fuel burning , deforestation- Anthropogenic increase : 30%- Average atmospheric residence time: 500 years• Methane (CH4)- Source: Rice cultivation, cattle & sheep ranching,decay from landfills, mining- Anthropogenic increase: 145%- Average atmospheric residence time: 7-10 years• Nitrous Oxide (N20)- Source: Industry and agriculture (fertilizers)- Anthropogenic increase: 15%- Average atmospheric residence time: 140-190 years
  8. 8. Percentage of Carbon dioxide in the atmosphere
  9. 9. • This graph shows the different greenhouse gases and how much they are being released due to man – made activities
  10. 10. • The amount of different greenhouse gases that are emitted
  11. 11. Physicochemical effects Hydrocarbons + NOX >32 C UV higher Ozonetemperatures Temperature Inversion Lung Inflammation Respiratory disease
  12. 12. Effects • Increase in average Temperature temperature on Earth Increase • Earth becomes warmer • Sea level rising due Raised Sea to melting glaciers Level • More natural calamities Weather • More extreme weather
  13. 13. Health Effects Direct • heat physical • floods, droughts • allergens • vector-borne disease Biological • water-borne disease • food production, storage
  14. 14. Solutions • Reduce energy needs Conservation • Recycling • Nuclear • Wind Alternate • Geothermal energy sources • Hydroelectric • Solar • Fusion
  15. 15. Solutions
  16. 16. Solutions
