  1. 1. Earth’s Warming<br />By: Erin Shortall & Calvin Thomke<br />
  2. 2. Greenhouse Effect, Climate Change, Global Warming<br />Greenhouse Effect= the warming of Earth’s surface during the day, and the cooling of Earth at night, releasing the heat into the atmosphere, which is trapped by greenhouse gases. Average temperature of 59 degrees Fahrenheit.<br />Climate Change= long-term change in Earth’s climate, or of a region on Earth. May spur hurricanes, floods, droughts, famines, disasters.<br />Global Warming= direct result of adding too much carbon dioxide into atmosphere, causing Earth to heat. Average American releases 20 tons of carbon dioxide each year.<br />
  3. 3. How They Are Related.<br />Carbon Dioxide Greenhouse Effect Global Warming Climate Change<br />Carbon Dioxide goes into the atmosphere, which are then trapped by Greenhouse Gases. That blocks Earth from sunlight, causing Global Warming, making Earth warmer causing a climate change.<br />
  4. 4. Primary Causes<br />Greenhouse Gases<br />Humans<br />Fossil Fuels<br />Carbon Dioxide<br />Methane from landfills and agriculture<br />Nitrous Oxide from fertilizers<br />Gases from refrigeration and industry<br />Loss of forests that would store CO2<br />
  5. 5. Consequences<br />Hurricanes<br />Floods<br />Droughts<br />Famines<br />Disasters<br />
  6. 6. Global Warming Impacting Economy<br />Price of energy has gone up<br />Repairs needed for damages done by hurricanes, tidal waves, tornadoes, etc.<br />^ Repairs are very costly<br />
  7. 7. Fighting Global Warming<br />Plant and protect trees<br />“Go green.”<br />Electric cars to decrease pollution from cars.<br />Different methods of transportation<br />Solar panels<br />Natural fueling instead of fossil fuels<br />
  8. 8. Arguments Against It<br />Most scientists think human activities do not impact global warming or the Earth’s climate.<br />Some scientists say reliable sources of temperature show no global warming trend.<br />
  9. 9. Personal Opinions<br />We believe in Global Warming, however, based on the 0.75 degree increase in a century, it would take a very long time to actually affect us.<br />
