Understanding and Assessing Impacts
Kings County is already experiencing the impacts of climate change in six particular areas: coastal flooding, inland flooding, sea level rise, storm surge, infrastructure saltwater intrusion, and erosion. For instance, due to saltwater intrusion, the Municipality has spent between 2 and 3 million dollars in the last several years extending municipal water services to the community of Kingsport. Climate change is only expected to worsen. The Nova Scotia Department of Environment estimates that temperatures in Kings County could be, on average, 3°C warmer by 2050 than in the 1990s. This means milder winters and hotter summers. It is also estimated that precipitation in the area could increase by up to 12 percent by 2050, but that the increase will come in the form of less-frequent, more-violent weather events. Finally, there is likely to be an increase of extreme weather events, such as hurricanes and blizzards. Climate change will have implications in areas of agriculture, forest composition, wetlands, soils and erosion. For instance, Increased precipitation and a warmer climate will have an impact on both natural and introduced vegetation. Some native species of trees may be unable to adapt and could enter a period of decline. High value softwood trees such as spruce and fir may be especially vulnerable. However, the effects of climate change will not be completely negative. As Kings County warms, there could be an increase of up to 30 growing days by 2050 and fall harvesting will become easier. It is also likely that the range of crops grown in Kings County could be expanded to include less hardy crops, such as certain varieties of grapes and more diverse fruits and vegetables. However, pest insect larvae that are normally killed by cold winter temperatures may survive through the winter as temperatures rise. As the incidences of pests grow, so too could pesticide use.
