The effects of global warming

  1. 1. Prepared by Fariz Azam Nisa Sher
  2. 2. 5 deadliest effect of globalwarming The melting of the ice caps in the polar region The economic consequences Increased probability and intensity of drought and heat waves Warmer waters and more hurricanes Spread of diseases
  3. 3. 1.The melting of the ice caps in the polarregion The melting of the ice caps will cause the sea level to rise. There are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 230 feet. That’s not going to happen all at once, but still, the sea level will rise.
  4. 4.  As the consequences, the melting of the ice caps will change the landscapes of the artic. If more ice melts, it means that there are less land areas for creatures living in the artic. Living creatures such as polar bears need the ice in the artic as their living ground and shelter.
  5. 5. When the ice melts, polarbears will lose their habitatand they will be in greatdanger since they dependslargely on the ice caps fortheir continuity of life.
  6. 6. 2. The economicconsequences According to a 700-page report written by former World Bank chief economist Nicholas Stern, hundreds of millions of people could suffer from hunger, water shortages and coastal flooding as the Earth gets warmer. This could cause us lots of money since we have to spend more money on food and water, and more money to build land areas for people to live in. If temperatures rise by 3 degrees Celsius, rising sea levels and flooding could displace 200 million people.
  7. 7. When the temperature rises,the ice melts and the sealevel will rise. The increasein sea level will make itpossible for floods to happenin areas where there areseas. Houses and buildingswill be destroyed and largeamount of money will beneeded to build them back.
  8. 8. 3. Increased probability and intensity ofdrought and heat waves What is heat waves? A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. The temperatures that people from a hotter climate consider normal can be termed a heat wave in a cooler area.
  9. 9. 35 to 40 degree Celsiusmight be usual to us,but it might be unusualto the Eskimos sincethey are used to thetemperature below 0degree Celsius. That iswhat they will call heatwaves.
  10. 10.  Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves. Africa will receive the worst of it, with more severe droughts also expected in Europe. Water is already a dangerously rare commodity in Africa, and according to the Intergovernmental Panel on Climate Change, global warming will only worsen the conditions.
  11. 11. With merely dry lands in thearea, it is almost impossiblefor the people living in thatarea to grow crops tosupport their living. Thiswill cause food shortageand even famine.
  12. 12. 4. Warmer waters and more hurricanes As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes. The most devastating hurricane was the Katrina which happened in the year 2005 in the United States. It produced catastrophic damage - estimated at $75 billion in the New Orleans area and along the Mississippi coast - and is the costliest U. S. hurricane on record. Katrina is also responsible for approximately 1200 reported deaths, including about 1000 in Louisiana and 200 in Mississippi.
  13. 13. 5. Spread of diseases As the temperature gets hotter, the climate changes drastically. Vectors such as mosquitoes adapted well to the changes in their ecology and became stronger. They developed in their body system in order to adapt to the climate change and so did they develop new diseases. As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them. Indeed, many scientists point to global warming as a factor in the spread of malaria and other vector-borne infectious diseases.
  14. 14. conclusion  As a conclusion, the causes and the effects of global warming is inter-connected with each other. Temperature The sea water The ice caps rises becomes hotter melts Drought and Coastal floods Sea level rises heat waves and flash floodsFood and water shortage, Damage buildings Big loss famine and death and homes
