1. Global Carbon Cycle and Global Climate Change Ecology: Science Behind Environmental Issues Spring 2010

2. Global Carbon Cycle(simple view) EoE- http://www.eoearth.org/article/Carbon_cycle

3. Main “Resevoirs” for Carbon Atmosphere Rocks Including fossil fuels Water Living Organisms

4. Humans Have Altered the Global Carbon Cycle Burning Fossil Fuels Increases the rate of movement of carbon from “rocks” to “atmosphere” Deforestation Lower number of plants photosynthesizing decreases the rate that carbon moves from “atmosphere” to “living organisms” Burning Trees Increases the rate that carbon moves from “living organisms” to the atmosphere

9. Carbon Dioxide is a Greenhouse Gas Electromagnetic energy from the sun is transmitted through carbon dioxide Infrared radiation (heat) is absorbed by carbon dioxide and reradiated

10. Greenhouse Effect

11. Global Climate Change 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 She was a member of the Intergovernmental Panel on Climate Change as was awarded a Nobel Prize as part of that group. Her full presentation and other info is available at http://katharinehayhoe.com/

29. What experiment can we conduct to “prove” that human activity is causing global warming?We only have one planet, so we can’t do a controlled, replicated, manipulative experiment?Thus, we have to rely on mathematical models.
