Climate services in support of climate change impact analyses for the German inland transportation system

Climate change and extreme weather events are an increasing challenge for society and the economy, including the transport sector. A sustainable and resilient transportation system therefore requires information on the temporal and spatial pattern of risks induced by climate change and the assessment of resulting vulnerabilities. Such analyses in the past were usually made separately for each mode of transport based on different observational and climate model datasets and using different methodological approaches to analyse climatic changes and their impacts on the transport infrastructure. Within the research network “BMDV Network of Experts” an intermodal perspective is taken on transportation. Common observational and climate model datasets as well as a standardized analysis framework were coordinated and agreed upon to form the basis for comparable climate impact assessments for roads, railways and inland waterways. This manuscript introduces the climatological datasets and methodological approaches for the climate change and climate impact analysis used for the transportation sector and beyond. Selected results on the projected increases of extreme temperature and heavy precipitation are exemplarily presented in order to illustrate the need for developing climate change adaptation measures for the German inland transport system.
