Global Warming Is Uncool Global Warming Is Uncool Presentation Transcript

  • Negative impacts on Temperature
    • Average temperatures have climbed
    • 1.4 degrees Fahrenheit around the
    • world since 1880, according to NASA's
    • Goddard Institute for Space Studies.
    • The United Nations' Intergovernmental
    • Panel on Climate Change (IPCC) reports
    • that 11 of the past 12 years are among the
    • dozen warmest since 1850 .
  • Human-made gases
    • Worldwide man-made emissions of carbon dioxide -- the main gas that causes global warming -- jumped 3 percent last year, international scientists claim.
    • 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.
    • 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.
  • Amount of Greenhouse Gases
  • Effects of Global Warming
    • Scenarios studied by the Intergovernmental Panel on Climate Change predict that global warming will continue and get worse much faster than was expected.
    • 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.
  • Trends in Global Warming
    • Shows the increasing temperature from the year 1880 to the year 2000.
  • Alternatives
    • There are many alternatives to
    • omitting greenhouse gases. There are
    • choices such as renewable energy sources
    • such as dams, or electricital powered cars.
    • If many people make the decision to take
    • action and carpool, ride the bus, or simply
    • use more effective light bulbs is a step
    • forward to decreasing the impact of global
    • warming.
