Greenhouse Effect

  1. 1. What is Greenhouse Effect ? O The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
  2. 2. Some Works on Greenhouse Effect
  3. 3. O The existence of the greenhouse effect was argued for by Joseph Fourier in 1824.
  4. 4. O John Tyndall declares the reasoned experimental observations in 1859.
  5. 5. O Svante Arrhenius revised the observations of John Tyndall in more numerical datas in 1896.
  6. 6. O Global warming refers to a rise in the temperature of the surface of the earth O An increase in the concentration of greenhouse gases leads to an increase in the magnitude of the greenhouse effect ( called enhanced greenhouse effect
  7. 7. Causes of Greenhouse Effect OGreenhouse Gases: By their percentage contribution to the greenhouse effect on Earth the four major gases are: water vapor, 36–70% carbon dioxide, 9–26% methane, 4–9% ozone, 3–7% O Ozone Layer Depletion: A variety of biological consequences such as increases in sunburn, skin cancer, cataracts, damage to plants, and reduction of plankton populations in the ocean's photic zonemay result from the increased UV exposure due to ozone depletion.
  8. 8. O Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress. O Extreme high air temperatures contribute directly to deaths from cardiovascular and respiratory disease, particularly among elderly people. In the heat wave of summer 2003 in Europe for example, more than 70 000 excess deaths were recorded. O Climate change is expected to cause approximately 250 000 additional deaths per year between 2030 and 2050; 38 000 due to heat exposure in elderly people, 48 000 due to diarrhoea, 60 000 due to malaria, and 95 000 due to childhood undernutrition.
  9. 9. Increased Temperature
  10. 10. Rising Sea Level
  11. 11. Habitat Damage and Species Extinction
  12. 12. More Severe Storms
  13. 13. Droughts
  14. 14. Reduce, Reuse, Recycle Buying products with minimal packaging will help to reduce waste. By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually
  15. 15. Replace Your Light Bulbs Wherever practical, replace regular light bulbs with compact florescent light (CFL) bulbs. Replacing just one 60-watt incandescent light bulb with a CFL will save you $30 over the life of the bulb. CFLs also last 10 times longer than incandescent bulbs, use two-thirds less energy, and give off 70 percent less heat. If every Canadian family replaced one regular light bulb with a CFL, it would eliminate 90 billion pounds of greenhouse gases, the same as taking 7.5 million cars off the road.
  16. 16. Use the "Off" Switch Save electricity and reduce global warming by turning off lights when you leave a room, and using only as much light as you need. And remember to turn off your television, stereo and computer when you're not using them. It’s also a good idea to turn off the water when you’re not using it. While brushing your teeth, shampooing the dog or washing your car, turn off the water until you actually need it for rinsing.
  17. 17. Plant a Tree If you have the means to plant a tree, start digging. Trees absorb carbon dioxide and give off oxygen. A single tree will absorb approximately one ton of carbon dioxide during its lifetime.
  18. 18. Encourage Others to Conserve Share information about recycling and energy conservation with your friends, neighbors and co-workers, and take opportunities to encourage public officials to establish programs and policies that are good for the environment.
  19. 19. Not All Scientists Agree While the majority of mainstream scientists agree that global warming is a serious problem that is growing steadily worse, there are some who disagree. John Christy, a professor and director of the Earth System Science Center at the University of Alabama in Huntsville is a respected climatologist who argues that global warming isn't worth worrying about.
  20. 20. Christy reached that opinion after analyzing millions of measurements from weather satellites in an effort to find a global temperature trend. He found no sign of global warming in the satellite data, and now believes that predictions of global warming by as much as 10 degrees Fahrenheit by the end of the 21st century are incorrect.
