Shauna and Amanda-Period 5

  1. 1. Global Warming<br />By Amanda and Shauna<br />
  2. 2. What is the greenhouse effect? Climate Change? Global Warming?<br />Greenhouse Effect<br />-natural keeps climate warm and habitable<br />-Man Made burning fossil fuels<br />Climate Change<br />-affects people and our environment<br />Global Warming<br />-average increasing temperature<br />-increased emission of greenhouse gases from human activity<br />
  3. 3. How are each greenhouse effect, climate change, and global warming related?<br />Greenhouse Effect<br />Greenhouse Effect traps heat in atmosphere to make Earth heat up<br />Climate Change related by rising temperatures<br />Global Warming heats atmosphere to make oceans rise<br />
  4. 4. What are the primary causes of global warming?<br />Humans create emissions of greenhouse gases<br />Primary gas is carbon dioxide<br />Natural causes can create global warming<br />Volcanic eruptions<br />Sunspots<br />Wobbling Earth<br />
  5. 5. What are the possible consequences if we do not work to stop global warming?<br />Wildlife would be in danger<br />Glaciers melt to make sea levels rise<br />Severe heat waves<br />Weather increasing(such as wild fires, hurricanes, typhoons, tornados, thunder storms, ect.)<br />
  6. 6. How is global warming impacting economy?<br />Will consume our national resources and threaten the well-being of future generations<br />Droughts and loss of soil can impact agricultural communities<br />More frequent wildfires, slower growing for trees, and increased prevalence of pests could decrease timber industry revenue of $1 to $2 billion per year<br />
  7. 7. What are several ways we can all fight Global Warming?<br />Move thermostat down 2° in winter and up 2° in summer<br />Chose energy efficient appliances<br />Take a shower instead of a bath<br />Clean/replace filters on furnace/air conditioner<br />Replace regular light bulbs with fluorescent bulbs<br />
  8. 8. What is the basic argument(s) against global warming?<br />Over 17,000 scientists believe there is no convincing scientific evidence that human activities threaten to disrupt Earth’s climate<br />The most reliable sources of temperature data show no global warming trend<br />A natural amount of global warming would be beneficial<br />Efforts to reduce human greenhouse gas emissions would be costly and wouldn’t stop a change in Earth’s climate<br />
  9. 9. What are your personal opinions about global warming?<br />Global warming is a natural process <br />Humans are not the cause of it, but it is possible that we are helping it along<br />There is no point in putting in costly programs because nature will take its course anyway<br />
