Projecting Future Insured Coastal Flooding Damages with Climate Change

Estimates of future damages from climate change in coastal areas are of growing interest for climate change research and policy-making. A newly-developed methodology is applied to estimate total insured coastal damages with climate change for the period 2025-2085 in New York State, USA. Total damages without adaptation include future insured damages from economic growth and additional damages from climate change due to increases in flood frequency, based on two sea level rise scenarios. Data and methodological issues are discussed, and a comparison with the results of a metro New York City flood damage study using different data and methods is presented.
