Abstract
A challenge for coastal conservation over the next decades is to predict and then effectively manage the outcomes of ongoing climate change in the context of the Anthropocene. Paraglacial coasts are those on or adjacent to present or formerly glaciated terrain and which are still influenced by glacigenic processes. Ongoing response of paraglacial coasts to the influences of glaciation can give rise to diverse regional-scale coastal responses that may variously amplify or suppress any effects caused by global climate change. Here we provide insight into the richness of landforms and coastal system responses from two contrasting paraglacial environments, in Svalbard where glaciers are still present but are actively retreating, and in Ireland where late Pleistocene glaciers melted away around 14,000 years ago. Svalbard and Ireland exhibit different paraglacial coastal responses which reflect long-term variations in sediment supply from inland source areas to the coast, and variations in sediment residence times and storage areas within the coastal zone. The conservation of paraglacial coasts in the context of Anthropocene global warming requires an understanding of regional glacial history and longer term coastal responses to paraglacial relaxation.
