Uncertainty is indeed a major challenge in climate change science. Also it is identified as a barrier for all policy cycle stages (Clar et al., 2013), which may sometimes hinder adaptation decisions (Hanger et al., 2013). This appears to be relevant not only to countries which are in an early stage in adaptation policy process, but also to countries that have already made progress. In the self-assessment survey, for example, five countries which stated that uncertainties related to climate change projections have been already included in adaptation policies, reported that additional information is still needed on this topic (Austria, Denmark, Italy, Poland, Portugal).
