The goal of this paper is to bring a risk‐based mindset to the challenge of climate change and its effects on atmospheric perils of relevance to catastrophe modeling. Section 1 summarizes some key elements of climate and climate change and its relevance for weather extremes.

Future coastal flood risk will be strongly influenced by sea-level rise (SLR) and changes in the frequency and intensity of tropical cyclones. These two factors are generally considered independently. Here, we assess twenty-first century changes in the coastal hazard for the US East Coast using a flood index (FI) that accounts for changes in flood duration and magnitude driven by SLR and changes in power dissipation index (PDI, an integrated measure of tropical cyclone intensity, frequency and duration).
