A note from the Author

Climate change is leading to more frequent and extreme events. The potential for catastrophe is rising in line with global temperatures. Coastal areas in Ireland are some of the most prone to extreme events, but this risk is not evenly distributed. In this paper we look a the pattern of risk around the Irish coastline, with particular reference to newly built property and provide estimates of total potential loss.
