Vertical land movement, caused by sediment settling, groundwater extraction, and tectonic forces, can boost or reduce the local effects of global sea level rise. Conventional wisdom says that the offshore collision of two continental plates is pushing up Washington’s and Oregon’s coastlines. This assumption may make coastal communities complacent about climate change and sea level rise. Using tidal-gauge and GPS readings, Washington Sea Grant’s Ian Miller and colleagues have found that vertical land movement actually varies dramatically along Washington’s shores. While the Olympic Coast’s northwest corner is rising, the land is actually subsiding as little as 30 miles down the coast – and along densely populated Puget Sound. Communities need local data to prepare for rising seas.

New Jersey Coastal Community Resilience Demonstration Project: Pilot Communities: Cape May Point, Little Silver, Oceanport
Coastal communities across the nation are faced with the challenge of how to adapt to coastal inundation associated with climate change and sea level rise. As part of the National Sea Grant Coastal Communities Climate Adaptation Initiative (CCCAI), the New Jersey Sea Grant Consortium (NJSGC) and its partners, New Jersey Department of Environmental Protection Office of Coastal Management (NJOCM), Monmouth University Urban Coast Institute (UCI) and Stevens Institute of Technology, conducted community-based, climate adaptation demonstration projects in Cape May Point, Little Silver and Oceanport, New Jersey.
