Since the year 1864, the temperature in the Canton of Aargau has increased by 2 °C. If global greenhouse gas emissions continue to rise in the future, the warming will continue and will amount to further 2.3 °C by 2060 with respect to the mean of the period 1981-2010. Only an effective lowering of emissions can limit the future temperature change. However, adaptation to the impacts of climate change in the Canton of Aargau would be required even in this case.
Climate change in the Canton of Aargau
The CH2018 Climate Scenarios provide a Swiss-wide picture on how climate variables such as temperature and precipitation will change throughout the 21st century. They are now complemented by the corresponding information for each individual Swiss canton. Human-made climate change will lead to a further increase of both winter and summer temperature in the Canton of Aargau. Mean precipitation amounts will tend to decrease in summer and to increase in winter. The magnitude of these changes will depend on the future greenhouse gas emissions. Two different emission scenarios are considered here: Stringent future emission cuts (RCP2.6) and a continued increase of emissions (RCP8.5).
Besides understanding future changes in mean temperature and mean precipitation amounts, developing robust and sustainable mitigation and adaptation strategies also requires information on changes in the frequency and intensity of extremes and changes of sector-specific climate indicators. As an example, increases in the number of hot days, drier summers, more intense precipitation events and more frequent snow-scarce winters are projected for the future. The figure below presents an overview on future changes in extreme events projected for the Canton of Aargau by the year 2060 in case of continuously rising greenhouse emissions (scenario RCP8.5).
