Sea level rise
Justification for indicator selection
Sea-level rise (SLR) results from thermal expansion of the oceans (the increase in volume due to rising ocean water temperature) and increased inflow of melt-water from glaciers and ice-sheets (in particular the Greenland and west Antarctic ice sheets). Thus it is an important indicator of climate change, with great relevance in Europe for flooding, coastal erosion and the loss of flat coastal regions. Rising sea levels increase the likelihood of storm surges, enforce landward intrusion of salt water and endanger coastal ecosystems and wetlands. Coastal areas in Europe often contain important natural ecosystems, productive economic sectors, and major urban centres. A higher flood risk increases the threat of loss of life and property as well as damage to sea-dikes and infrastructure, and could lead to an increased loss of tourism, recreation and transportation functions (Nicholls and Tol, 2006; Nicholls et al., 2007; Devoy, 2008). Low-lying coastlines with high population densities and small tidal ranges will be most vulnerable to SLR (Kundzewicz, 2001). Thus coastal flooding related to SLR could affect a large population (Arnell, 2004; Nicholls, 2004). Because of the slow reaction of the climate system, climate change mitigation will not reduce these risks over the coming decades to any significant degree, but various options for adaptation exist.

Policy context and targets
In April 2009 the European Commission presented a White Paper on the framework for adaptation policies and measures to reduce the European Union's vulnerability to the impacts of climate change. The aim is to increase the resilience to climate change of health, property and the productive functions of land, inter alia by improving the management of water resources and ecosystems. More knowledge is needed on climate impact and vulnerability but a considerable amount of information and research already exists which can be shared better through a proposed Clearing House Mechanism. The White Paper stresses the need to mainstream adaptation into existing and new EU policies. A number of Member States have already taken action and several have prepared national adaptation plans. The EU is also developing actions to enhance and finance adaptation in developing countries as part of a new post-2012 global climate agreement expected in Copenhagen (Dec. 2009).
