(though regional studies provide a useful <br />framework for assessing the impacts of <br />climate change on fish and wildlife across <br />the Southeast, state - specific information will be criti- <br />cal for updating the North Carolina Wildlife Action <br />Plan (NC WAP) (NCWRC 2005). Fortunately, a <br />number of climate modeling and scenario tools are <br />available to project potential shifts in temperature and <br />precipitation in the state. In this chapter, we apply <br />climate modeling scenarios to map state - specific <br />projected temperature and precipitation changes. We <br />also provide a review of recent studies on projected <br />sea - level -rise for the coast of North Carolina. In each <br />section, we use the information from the projections <br />to identify a broad subset of species and habitats in <br />North Carolina that may be particularly susceptible <br />to climate change impacts in the state. <br />l,u 1 <br />fror NoII "th ° a1a"'oill'no <br />Climate Wizard (Zganjar et al. 2009) is a useful <br />mapping tool that can be used to derive temperature <br />projections for North Carolina for the middle and <br />end of this century. This user - friendly tool allows <br />users to access past changes in climate, as well as <br />project future changes in rainfall and precipitation in <br />a given area based on available climate models statis- <br />tically downscaled to a 12 km2 resolution (Maurer et <br />al. 2007). The projections presented in this section <br />are based on multi -model ensemble averages of 16 <br />global circulation models (GCMs) using the high <br />emissions scenario (A2) from the IPCC. Estimates <br />of mean temperature departures are provided for <br />mid - century (2040 — 2069) and end of century <br />(2070- 2099). <br />in a <br />Based on projections using Climate Wizard, average <br />yearly temperatures across the state are expected to <br />increase 3.5 to 4.7 °F by mid century. The areas of <br />highest temperature increase will be in the north and <br />west of the state and in many of the mountainous <br />regions. Coastal areas are also projected to experience <br />significant yearly average temperature increases, but <br />to a lesser degree than inland areas. By the end of the <br />century, projections show increases in annual aver- <br />age temperatures of 5 to 6T, again with the greatest <br />increases in the north and west portions of the state <br />(Figure 3 -1). <br />In addition to changes in average annual tempera- <br />ture, seasonal, monthly, and maximum/ minimum <br />daily temperatures can sometimes provide more <br />meaningful projections for assessing the impact of <br />temperature changes on species and ecosystems. <br />Climate Wizard can easily be used to complete <br />this type of analysis. Figure 3 -2 shows projected <br />change in temperature in North Carolina by season <br />for the end of the century. The largest increase in <br />temperature (7.8 °F) is projected to occur in the <br />summer months between June and August, while <br />the lowest increases in temperature are projected to <br />occur during the fall and winter. Other tempera- <br />ture related variables, such as number of frost free <br />days or length of the growing season are also <br />biologically important. Although, Climate Wizard <br />does not provide these outputs directly, many <br />climate modelers are interested in working with state <br />agencies and other partners to identify the data and <br />information needs required to facilitate climate <br />change adaptation for wildlife. University research- <br />ers as well as many of the federal initiatives are identi- <br />fied in Appendix E. <br />Chapter 3: Projected Impacts of Climate Change in North Carolina 53 <br />
