Europe’s climate is projected to undergo significant changes in the coming decades. Without adaptation measures, this will have a variety of socioeconomic impacts, among which are impacts to the transport infrastructure due to increased flood events. Sometimes, gradual changes in climate have disproportionally large effects on socioeconomic systems, causing them to function fundamentally different. We refer to those changes as socioeconomic tipping points (SETPs). The potential occurrence of SETPs may require significant changes in adaptation strategies of EU member states.
