Over the centuries, the region has made major investments along its coastline. Homes, businesses, rail lines, airports, factories, power plants, and other infrastructure has been built in places that are now threatened by the effects of climate change, primarily storm-related flooding and permanent sea-level rise. Adapting these densely populated communities and critical infrastructure is complicated and expensive, and special consideration will be required in socially vulnerable neighborhoods. But where the densities justify it, investments must be made in resilience projects that will ensure the region continues to thrive in the era of climate change.
