Short summary

This work examines relationships between coastal hazard, exposure, and vulnerability to describe trajectories of risk at the county scale along the US Atlantic coast over the past 5 decades. Our findings suggest that modelling efforts to predict future coastal risk need to address feedbacks between hazard, exposure, and vulnerability to capture emergent patterns of risk in space and time.
