Route Fifty: Crowdsourcing King Tides to Better Understand Rising Sea Levels

Route Fifty: Crowdsourcing King Tides to Better Understand Rising Sea Levels. “King tides are especially high tides that are amplified by astronomical events including the perihelion, when the Sun is closest to Earth in its orbit in early January. In low-lying coastal cities, like Miami Beach, Florida and Norfolk, Virginia, the highest tides of the year can bring flooding and give planners, local officials and the public a good opportunity to measure the incremental impacts of a changing climate. But like all tides, they’re also influenced by local topography. Washington state has more than 3,300 miles of coastline, which includes the various islands and inlets that comprise Puget Sound and its adjacent waterways.”
