Flood Risk on Rise for New York City, New Jersey Coast, Study Finds

For the first time, climate researchers compared both sea-level rise rates and storm surge heights in prehistoric and modern eras and found that the combined increases of each have raised the likelihood of a devastating 500-year flood occurring as often as every 25 years.

Sea level also matters in a horizontal direction. A rule of thumb is that 1 inch of vertical change in sea level translates into 100 inches of horizontal loss on a flat beach or marsh. In this way, a little bit of sea level rise can translate into a lot of water moving inland when there are storms or abnormally high tides.
