20. What Will Happen Next? Presented in Order from Most to Least Likely

21. Certain change Atmospheric CO2 will continue to increase

23. Extremely Likely Water and air temperature will continue to increase

24. “Simulations of the response to natural forcings alone … do not explain the warming in the second half of the century” SPM Stott et al, Science 2000

25. “..model estimates that take into account both greenhouse gases and sulphate aerosols are consistent with observations over this period” SPM Stott et al, Science 2000

28. Management Strategy for Coping with Increased Sea Level Rise Coastal forests will be inundated and coastal beach erosion will increase. Forest managers should work with land owners at a local scale to plant mangroves and other soil retention vegetation to delay terrestrial loss for a long as reasonably possible.

29. Likely Impacts

30. Changing Patterns in Wildfire Occurrence

34. Large scale (> 400 ac) Wildfires and Air Temperature From Westerling et al. 2005

35. Management Strategy for Coping with Increased Wild Fire Manage for and encourage more fire tolerant grass and tree species Increase public education and preparedness regarding wild fire prevention and individual preparation and control Compared to climatic drivers, fuel reduction control measures will be largely ineffectual

36. Likely Impacts Inter-annual precipitation variability and soil erosion

39. Areas of Soil Erosion By 2030 On UNF

40. Management Strategy for Coping with Increased Soil Erosion Continue to encourage standard soil erosion control practices such as contour plowing, winter cropping, shelter belts, and buffer strips Relocate trails away from streams Use bridge mats and culverts at stream crossings

41. Likely Impacts Changes in Productivity and Economic Value

44. Timberland Acreage Shift 1993 – 2040: No Climate Change Baseline > 25% DECLINE 5%-25% DECLINE <5% CHANGE 5%-25% INCREASE

45. Timberland Acreage Shifts by 2040 Due to Hadley Climate Change 5%-25% DECLINE <5% CHANGE 5%-25% INCREASE

46. Management Strategy for Coping with Changing Rangeland and Forest Productivity Work with local land owners to examine alternative crops (e.g., shift from red pine to loblolly pine plantations or from corn to wheat) as climate shifts occur Examine options for changing management strategy for exists crops (e.g., wider tree planting, fewer head per acre)

47. Less Likely Impacts Gradual Ecosystem Shifts
