"The frequency of high-tide flooding has doubled in 30 years. Some cities faced more than 20 days of it in the past year, and not just during hurricanes. "
"The nation's coasts broke records for tidal flooding over the past year as storms combined with rising seas to inundate downtown areas of Miami, Boston and other major cities, according to a federal report released Wednesday.
While some of the flooding coincided with hurricanes and nor'easters, much of it was driven mainly by sea level rise fueled by climate change, scientists with the National Oceanographic and Atmospheric Administration (NOAA) write.
The oceans are rising about 3 millimeters a year on average, driven primarily by melting land ice and warming water, which expands. That rate is accelerating, and it has led to a steady increase in U.S. coastal flooding in recent decades, the report shows. Several cities—including Boston, Atlantic City, and Sabine Pass, Texas—saw more than 20 days of high-tide flooding between May 2017 and April 2018, the "meteorological year" covered by the report."
