Global Carbon Cycle And Global Change

  1. 1. Global Carbon Cycle and Global Climate Change<br />Ecology: Science Behind Environmental Issues<br />Spring 2010<br />
  2. 2. Global Carbon Cycle(simple view)<br />EoE- http://www.eoearth.org/article/Carbon_cycle<br />
  3. 3. Main “Resevoirs” for Carbon<br />Atmosphere<br />Rocks<br />Including fossil fuels<br />Water<br />Living Organisms<br />
  4. 4. Humans Have Altered the Global Carbon Cycle<br />Burning Fossil Fuels<br />Increases the rate of movement of carbon from “rocks” to “atmosphere”<br />Deforestation<br />Lower number of plants photosynthesizing decreases the rate that carbon moves from “atmosphere” to “living organisms”<br />Burning Trees<br />Increases the rate that carbon moves from “living organisms” to the atmosphere<br />

  8. 8. Mauna Loa Curve<br />EoE- http://www.eoearth.org/image/Mauna_loa_curve.jpg<br />
  9. 9. Carbon Dioxide is a Greenhouse Gas<br />Electromagnetic energy from the sun is transmitted through carbon dioxide<br />Infrared radiation (heat) is absorbed by carbon dioxide and reradiated<br />
  10. 10. Greenhouse Effect<br />
  11. 11. Global Climate Change<br />Unless otherwise noted, all slides are from a presentation developed by Katharine Hayhoe, a Research Associate Professor in the Department of Geosciences at Texas Tech University<br />She was a member of the Intergovernmental Panel on Climate Change as was awarded a Nobel Prize as part of that group. <br />Her full presentation and other info is available at<br />http://katharinehayhoe.com/<br />
