No.: IPCC/ERO-0162965What is Global Warming?: What is Global Warming? *An increase in the average temperature of the Earth *Recent debate, but has been looked at by scientists for centuriesWhat causes it?: What causes it? * CO 2 * Methane * Nitrous oxide * Fluorinated compounds Greenhouse Gases: Human Impacts-What causes it?: What causes it? Natural Impacts: * Volcanoes *Water vapor * clouds * Change in sun’s energy outputWho’s Responsible?: Who ’ s Responsible? Burning of fossil fuels is main cause U.S. is leader in greenhouse gasses Human impacts are changing the composition of the atmosphereSlide 6: What are Causes of Global Warming? What is air pollution? -The presence in the air of substances which pose a potential threat to human health and/or the environment. -The presence of particles in the air which decrease visibility -The U.S. EPA estimates that 50 percent of the U.S. population is exposed to air pollutants exceeding current federal standards.Slide 7: Energy production from fossil fuels -Carbon dioxide, sulfur oxides, particulates -Increase in greenhouse gases, acidic precipitation Air PollutionSlide 8: Automobiles, other transportation sources -Carbon dioxide, nitrogen and sulfur oxides, products of incomplete combustion -Increase in greenhouse gases, acidic precipitation Air PollutionSlide 9: Refrigeration devices including home, commercial, and vehicles -Chlorofluorocarbons -Destruction of the stratospheric ozone layer Air PollutionSlide 11: The Carbon CycleEffects of Air Pollution and Global Warming: Effects of Air Pollution and Global Warming - Rising Sea Level -Change of precipitation and local climate conditions; acid rain -Alteration of forests and crop yields - Expansions of deserts into existing rangelands - More intense rainstorms -Not all long-term effects can be determinedSlide 13: What Is Being Done: Alternatives Renewable Energy Sources Solar Energies Wind Power Biomass GeothermalChanges In Vehicle Systems: Changes In Vehicle Systems Hybrid Fuel Cell Battery-ElectricConclusion: Conclusion Responsibility to improve environmental conditions lies upon all of us as individuals Concentrate on preventing environmental degradation before it starts Alternatives are feasible and Can be UsedSlide 16: Thank You LKS You do not have the permission to view this presentation.
