Abstract
The adaptation to a changing future climate, e.g. with more extreme precipitation events, presents a major challenge for society. Without proper handling of larger water flows, it is probable that an increase in the strength and frequency of extreme precipitation events in Denmark will lead to more frequent floodings within both urban and rural areas, causing serious societal and economic damage. Expected change in precipitation patterns will furthermore lead to more frequent and longer dry periods in summer and increased amounts of precipitation in winter. Global observations of precipitation for the last 100 years show general geographical patterns in the change of total precipitation. Local and regional temporal variations are generally so large, however, that it is not possible to attribute such changes to anthropogenic climate change. This report provides a brief review of current knowledge with respect to observed and expected future precipitation change in Denmark, based on Danish as well as international studies since 2007. Both observations and model calculations are considered.
