Experts expect these <br />condition to continue well into the future, By mid-century. <br />Minnesotans can expect much warmer winters. more <br />severe summer heat waves. a higher frequency of very <br />heavy risen events. and a higher frequency of late grow Ing <br />season drought condit ons. <br />Marry communities in Minnesota rely on economies <br />rooted to agriculture and outdoor recreation, such as <br />wintertime tourism, inciudrng snow mobtling, ice fishing, <br />and skiing. Future climate conditions may stress agruaulturat <br />econonnies by delaying planting and fieldwork, increasing <br />disease and pest pressure, and reducing crop yields due to <br />cycles of flooding and dry spelh. Rapidly warming winter <br />temperatures will turn snowfall into rain and reduce <br />the depth and timing of Iake ice ooyer, affecting winter <br />recreation. <br />Extreme ra+nfali events will increase food risk, paittcularfy <br />in ftoodplain areas, disrupting transportation and utility <br />senrfce, and damaging property and infrastructure. In <br />addrtion, surface runoff may lead to sail erosion, lake <br />pollu"n, and reduced drinking water quality. Nutrient <br />runoff in particular, along with warner temperatures, are <br />likely to contnWte to a larger occurrence of harmful algal <br />blooms on waters, many valued for recreation_ Changing <br />6mate conditions are likely to strain the viability of <br />native species, including popular recreational fish: invite <br />encroachment by invasive species, and increase the <br />geographic range and types of ticks arxf mosquitoes. <br />Some of these trends are evident in the current climate <br />prulectlon data that are available However, because these <br />data are often averaged or summarized for large areas <br />over large time periods, they can mask the local peaks in <br />temperature and precipitation that can trigger disasters. <br />Until more finely -scaled climate projection data becorne <br />available to Minnesota planners and decision -makers. the <br />current data still remain useful for exploring the future <br />ahead and establishing a baseline understanding of what <br />our weather challenges may be moving forward. <br />31 REGION r, <br />Page I L - 4 <br />
