  4. 4. temperature can have serious effects on climate conditions & weather changes. This affect the frequency & severity of storms hurricanes & tornados distort seasons duration, increase cloud cover, change precipitation levels & wind patterns. Warmer sea surface temperature will cause frequent storms & hurricanes along the gulf coasts & southeastern Atlantic. A number of scientist have agreed that global warming is a serious warming is happening more quickly in same parts of the world than others. The formation of the Earth took places around 4.6 Billion years ago & since then its temperature is changing. It has been warmer in the past than it is today & at time much colder. But the most alarming fact is the speed at
  5. 5. which the Earth is now heating up. Before the first time history humans are the main factor of the Earth’s changing climate or as we have named it ‘GLOBAL WARMING’.
  6. 6. Target of Global Warming
  7. 7. CAUSES OF GLOBAL WARMING 1. Greenhouse Effect : The greenhouse effect was discovered on 1896 and is a natural process. To support life for billions of years it has kept our planet warm enough. But more heat is trapped in the atmosphere as the amount of greenhouse gases increases. The earth is getting hotter as the natural process has spread up.
  9. 9. 2. LIFE IN CITY It is not just that there are more people than ever before. It is also how we choose to live that puts a strain on our planet. Life is comfortable and convenient in large cities. But the energy this lifestyle needs has a high environmental cost.
  10. 10. LIFE IN CITY
  11. 11. 3. INCREASE POPULATION : One of the greatest factors in global warming is the in increasing number of people on the earth. During the past 100 years the world's population has grown nearly four times larger. This has led to a massive rise in the levels of greenhouse gases in the earth's atmosphere. The growth of towns and cities is called urban spread. This takes up land that could be used for food crops and also destroys the places where plants and animal live.
  13. 13. 4. AIR POLLUTION : There are different kinds of pollution. Some visible, some invisible, that contribute the global warming. Carbon dioxide a greenhouse gases is the main pollutant that is warming earth. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants and other human activities that involve the burning of fossil.
  15. 15. 5. Deforestation : Deforestation is clearing earth's forests on a massive scale often resulting in damage to the quality of the land. Forests still cover about 30% of the world's land area. Forests are cut down for many reasons but most of them are related to money or to peoples need to provide for their families. The biggest driver of deforestation is agriculture. Deforestation has many negative effects on the environment. The most dramatic impact is a loss of habitat for millions of speckles. It also drives climate change. Forest soils are moist, but without protection from sun blocking tree cover they quickly dry out. The quickest solution to deforestation would be to simply stop cutting down trees.
  17. 17. OTHER CAUSES OF GLOBAL WARMING 1. Ozone Layer : 2. Methane Gas : 3. Temperature : 4. Pollution :
  18. 18. Ozone layer The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 97–99% of the Sun's high frequency ultraviolet light, which is potentially damaging to the life forms on Earth. It is mainly located in the lower portion of the stratosphere from approximately 20 to 30 Km (12 to 19 mi) above Earth, though the thickness varies seasonally and geographically. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Its properties were explored in detail by the British meteorologist G. M. B. Dobson, who developed a simple spectrophotometer (the
  19. 19. Between 1928 and 1958 Dobson established a worldwide network of ozone monitoring stations, which continue to operate to this day. The "Dobson unit", a convenient measure of the columnar density of ozone overhead, is named in his honor.

  23. 23. POLLUTION
  24. 24. EFFECTS OF GLOBAL WARMING: 1. Ice is melting worldwide, especially at the earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica & Greenland & Arctic sea ice. 2. Sea level rise become faster over the last century. Sea levels are expected to rise between 7 & 23 inches by the end of the century & continue melting at the poles could add between 4 & 8 inches 3. Hurricanes & other storms are likely to become stronger 4. Species that depends on the one another may become out of sync.
  25. 25. 5. Floods & droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10% over the next 50 years. Less fresh water will be available. 6. Some diseases will spread such as malaria carried by mosquitoes. 7. Ecosystem will change – some species will move further & could become extinct.
  27. 27. ACID RAIN : Acid rain describes any form of precipitation with high levels of nitric & sulfuric acids. It can also occur in the form of snow, fog & tiny bits of dry material that settle to earth. Ratting vegetation & erupting volcanoes release some chemical that can cause acid rain but most acid rain falls because of human activities. The biggest culprit is the burning of fossil fuels by coal burning power plants factories & automobiles. Acid rain has many ecology but none is greater than its impact on lakes, streams, wetlands & other aquatic environments. Acid rain makes water acidic & causes them to absorb the aluminum that makes its way from soil into lakes & steams. This combination

  29. 29. DISAPPEARING WORLD: Many nations have laws offering protection to conservation reliant species: for example, forbidding hunting, restricting land development or creating preserves. Before greenhouse gases and global warming species were able to survive in their natural habitat. However the rapid increase of climate change has put animals at risk of becoming extinct. As global warming continues, species are no longer able to survive and their kind starts to deteriorate. This is a repeating cycle that is starting to increase at a rapid rate because of climate change therefore landing many species on the endangered species list.

  39. 39. ECO-FRIENDLY HOMES: Our home release almost a third of the greenhouse gas we produce. The good news is that there are several ways ranging from now our homes are built to the way we live inside them. By which we can reduce the amount of greenhouse we make.
  41. 41. Preservation of Forests and Oceans: Carbon is removed & trapped by the forest & oceans as part of their natural process. In turn they can decrease the amount of carbon dioxide in the atmosphere & limit the power of the greenhouse effect. Humans have upset earth’s natural balance by damaging forest polluting oceans & fossil fuels. Due to this reason we must work together to protect our precious trees & seas.
  42. 42. Preservation of Forests and Oceans
  43. 43. LESS WASTE: A large amount of our household waste ends up on solid waste landfills. These enormous trash dumps release methane a greenhouse gas as they vote. One easy was to cut the methane that is released is to reduce the amount of trash you produce & recycle as much as possible of what is left.
  44. 44. Less Waste
  45. 45. What can you do Prevent Global Warming? 1. Recycle as much waste as is possible by sorting your trash. 2. Compost all your food scraps for use in your garden. 3. Take used glass bottles & jars to a recycling centre. 4. Save & reread old comics & amazing or give them to a friend. 5. Donate old toys & cloths to thrift stores.
  46. 46. CONCLUSION: One Green Day By saving water & electricity each one of us can held fight climate change. You can go even fate a difference. The clothes you wear the foods you eat & the product you use all contribute to your personal carbon foot print simple everyday decision can make a huge difference to the amount of the greenhouse gas that your lifestyle contributes to our atmosphere.
