Coastal Real Estate and Rising Sea Level

Rapidly rising sea level and the future of our coasts

A new report by Climate Central presents the potential impacts due to flooding from projected sea-level rise on coastal communities around the world. This is based on its new digital elevation model called Portfolio Analysis Tool (PAT). The results are useful for planning, but even before it was released Boston and New York City had already taken actions to plan and mitigate sea-level rise impacts, and Florida recently appointed its first Chief Resilience Officer. Other coastal communities, large and small, would do well to follow those examples and consider the future presented in the Climate Central report.

There are a few undeniable truths about our current situation that underscore the need to act. First, sea level is rising, and it is rising at an accelerating pace in many locations. We can see this in the observational record provided by tide gauges up and down our coasts, as well as in the projections generated by any number of computer models. Second, the exact amount and rate of rise is both difficult to predict and highly variable depending on any number of local and regional factors.

      The New York Times reports, “With 130-Mile Coast, New Jersey Marks a First in Climate Change Fight New Jersey will become the first state to require that builders take into account the impact of climate change, including rising sea levels, in order to win government approval for projects, Gov. Philip D. Murphy announced on Monday. […]

      The LA Times reports,”The municipal bond market looks to satellites to help assess climate risk” The $3.8-trillion municipal-bond market has found a new tool in its effort to understand the effects of climate change: satellites orbiting Earth. Assessing climate risks is a particularly vexing problem given that U.S. state and local governments tend to give […]
