2. Forest cover plays a big part in regulating the global climate

4. Objective What is the relative effect of deforestation and the combined effects of deforestation and increase in CO 2 levels on the given parameters? Surface air temperature Surface runoff Soil moisture Precipitation

5. Methodology Panoply Simulation 2 – Simulation 1: Impacts of deforestation Simulation 3 – Simulation 1: Impacts of the combined effect of deforestation and increase in CO 2 emissions

6. Results Precipitation – Evapotranspiration – Wind convection Figure 2. Annual global impact of deforestation on precipitation. Figure 3. Annual global impact of the combined effect of deforestation and the increase of carbon dioxide emissions on precipitation.

7. Surface Air Temperature – “Net cooling associated with changes in albedo and evapotranspiration overwhelms the warming carbon cycle effects of deforestation.” (Bela, 2007) Forests have lower albedo than open land. (Cook, 2010) Snow in the arctic that has a high albedo Figure 4. Annual global impacts of surface air temperature. Figure 5. Annual global impacts of the combined effect of deforestation and the increase of carbon dioxide emissions.

8. Maximum Surface Air Temperature Figure 6. Annual global impacts of maximum surface temperature. Figure 7. Annual global impacts of the combined effect of deforestation and the increase of carbon dioxide emissions on maximum surface air temperature. Figure 8. Global impacts of deforestation on maximum surface air temperature during the summer season. Figure 9. Global impacts of the combined effect of deforestation and the increase in carbon dioxide emissions on maximum surface air temperature during the summer season. Deforestation decreases evapotranspiration which consequently increases surface air temperature.

9. Minimum Surface Air Temperature Figure 10. Annual global impacts of minimum surface temperature. Figure 2. Global impacts of deforestation on minimum surface temperature during the winter season. Figure 11. Annual global impacts of the combined effect of deforestation and the increase of carbon dioxide emissions on minimum surface air temperature. Figure 13. Global impacts of the combined effect of deforestation and the increase in carbon dioxide emissions on minimum surface air temperature during the winter season.

10. Soil Moisture Figure 14. Global impacts of deforestation on maximum surface air temperature during the summer season. Figure 15. Global impacts of the combined effect of deforestation and the increase in carbon dioxide emissions on soil moisture.

11. Surface Runoff Figure 16. Global impacts of deforestation on surface runoff. Figure 17. Global impacts of the combined effect of deforestation and the increase in carbon dioxide emissions on surface runoff.
