Published on

Its melting! Or is it freezing? Both warmer and colder temperatures!

  • Very good slide show, some slides were very close to the text color, you have alot of good information in there though. Also I think your description wasn't totally finished ?

T10 0766966 Global Warming Is Uncool

  1. 2. Negative impacts on Temperature <ul><li>Average temperatures have climbed </li></ul><ul><li>1.4 degrees Fahrenheit around the </li></ul><ul><li>world since 1880, according to NASA's </li></ul><ul><li>Goddard Institute for Space Studies. </li></ul><ul><li>The United Nations' Intergovernmental </li></ul><ul><li>Panel on Climate Change (IPCC) reports </li></ul><ul><li>that 11 of the past 12 years are among the </li></ul><ul><li>dozen warmest since 1850 . </li></ul>
  2. 3. Human-made gases <ul><li>Worldwide man-made emissions of carbon dioxide -- the main gas that causes global warming -- jumped 3 percent last year, international scientists claim. </li></ul><ul><li>Carbon dioxide is a by-product of the combustion of oil, gas, coal, wood (hydrocarbons) and can be identified with vehicle exhausts, coal fires etc. </li></ul><ul><li>Hydrofluorocarbons (HFCS) Perfluorocarbons (PFC) Are a part of a group of compounds, containing fluorine in their make up, which have a very strong heating effect as well as depleting the ozone layer. </li></ul>
  3. 4. Amount of Greenhouse Gases
  4. 5. Effects of Global Warming <ul><li>Scenarios studied by the Intergovernmental Panel on Climate Change predict that global warming will continue and get worse much faster than was expected. </li></ul><ul><li>Sea levels will rise, glaciers will melt, the Arctic will get smaller, and agriculture patterns will be affected as a result. Secondary effects include extreme weather, more tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact. </li></ul>
  5. 6. Trends in Global Warming <ul><li>Shows the increasing temperature from the year 1880 to the year 2000. </li></ul>
  6. 8. Alternatives <ul><li>There are many alternatives to </li></ul><ul><li>omitting greenhouse gases. There are </li></ul><ul><li>choices such as renewable energy sources </li></ul><ul><li>such as dams, or electricital powered cars. </li></ul><ul><li>If many people make the decision to take </li></ul><ul><li>action and carpool, ride the bus, or simply </li></ul><ul><li>use more effective light bulbs is a step </li></ul><ul><li>forward to decreasing the impact of global </li></ul><ul><li>warming. </li></ul>
