1 Global warming is real RJ

  1. 1. By: Rachel Rhyner<br /> &<br /> Jaclyn McDermott<br />
  2. 2. Global Warming definition:<br /><ul><li>The theory that the world's average temperature is increasing due to the burning of fossil fuels and other forms of energy resulting in higher atmospheric concentrations of gases such as carbon dioxide
  3. 3. an increase of the earth's temperature by a few degrees resulting in an increase in the volume of water which contributes to sea-level rise</li></li></ul><li>Effects of Global Warming <br />
  4. 4. How we know its Real…<br /><ul><li> 800,000 years ago carbon dioxide levels were much lower, but know the atmosphere has higher levels
  5. 5. The concentration of greenhouse gases like co2, methane, nitrous oxide, and halocarbons have increased since industrialization
  6. 6. Arctic icecaps are declining at a rate of 9% due to global warming</li></li></ul><li>How we Know its Real Continued…<br />Global warming has changed precipitation patterns around the world, and disturbs agricultural practices that we depend on to live and earn money from.<br />Earth has been suffering from drought conditions since 1970 and has doubled.<br />Climate change is already killing150,000 people world wide every single year.<br />
  7. 7.
  8. 8. Global warming problems…<br /><ul><li>In 25 years deaths should double to about 300,000 people.
  9. 9. Tropical storms will get more intense with heavier precipitation and harder winds because of warmer ocean temperatures.
  10. 10. The warmer temperatures have helped mosquitoes thrive so there are more disease spreading like malaria.
  11. 11. Also coral reefs are dying out because they are so sensitive to temperature changes in the ocean.</li></li></ul><li>How does this Happen?<br /><ul><li>It happens because ofburning ofautomobiles, in factories, and electric power plants that giveenergy tohouses and offices. The burning of fossil fuels creates carbon dioxidein the atmosphere and pollutes the air.</li></li></ul><li>Quotes<br />“There are 20 different lines of evidence that the planet is warming,” <br />“We’re confident about what’s going on,” <br />
