Indicator Specification
Precipitation plays a vital role in all human-environment systems and sectors, including agriculture, water supply, energy production, tourism and natural ecosystems. Daily precipitation totals are standard meteorological measures that have been recorded systematically since the 1860s. However, despite longevity of the precipitation record in certain areas, the high spatial and temporal variability of precipitation means that the climate change signal cannot be detected with certainty in all European regions. Difficulties for detecting a significant trend can arise from the small sampling area of rain gauges, calibration errors in instrumentation, erroneous measurements during weather conditions such as snow or gales, and from limited sampling of the spatial variability of precipitation, such as in mountainous areas. Therefore, observed and projected precipitation changes should always be considered in the context of interannual variability and the measurement or modelling uncertainty.
In April 2013 the European Commission presented the EU Adaptation Strategy Package (http://ec.europa.eu/clima/policies/adaptation/what/documentation_en.htm). This package consists of the EU Strategy on adaptation to climate change /* COM/2013/0216 final */ and a number of supporting documents. One of the objectives of the EU Adaptation Strategy is Better informed decision-making, which should occur through Bridging the knowledge gap and Further developing Climate-ADAPT as the ‘one-stop shop’ for adaptation information in Europe. Further objectives include Promoting action by Member States and Climate-proofing EU action: promoting adaptation in key vulnerable sectors. Many EU Member States have already taken action, such as by adopting national adaptation strategies, and several have also prepared action plans on climate change adaptation.
The European Commission and the European Environment Agency have developed the European Climate Adaptation Platform (Climate-ADAPT, http://climate-adapt.eea.europa.eu/) to share knowledge on observed and projected climate change and its impacts on environmental and social systems and on human health; on relevant research; on EU, national and subnational adaptation strategies and plans; and on adaptation case studies.
No targets have been specified.
Trends are calculated using a median of pairwise slopes algorithm. Black dots represent high confidence in the sign of the long-term trend in the box (if the 5th to 95th percentile slopes are of the same sign). Boxes which have a thick outline contain at least three stations. Area averaged annual time series of percentage changes and trend lines are shown below each map for one area in northern Europe (Blue line, 5.6 to 16.9 °E and 56.2 to 66.2 °N) and one in south-western Europe (red line, 350.6 to 1.9 °E and 36.2 to 43.7 °N).
Projections are based on the EURO-CORDEX initiative (http://www.euro-cordex.net/). They have been obtained from different regional climate models (RCMs) performing at 11 km spatial resolution with boundary conditions from five global climate models (GCMs), using different RCPs.
