South Carolina Sea Grant Consortium is based in Charleston, S.C., one of the U.S. cities most threatened by a rising global sea level. More intense rainstorms combined with unusually high tides have communities rethinking traditional flood control structures.
As part of the National Sea Grant Coastal Communities Climate Adaptation Initiative (CCCAI), NJSGC is developing and implementing an education and outreach campaign designed to promote long term planning that will educate waterfront property owners and associated businesses about the need to gain an understanding of climate change and consider the potential impacts associated with it when planning for the future.
Scientists in Maryland have published numerous studies on the impacts of climate change on the Mid-Atlantic region, but communicating the results of that research has proved difficult. Many residents in the state’s coastal communities lack a good understanding of the risks that climate change and sea level rise in particular pose to their way of life. In 2012, Maryland Sea Grant held a statewide climate change forum to inform efforts to share and discuss the findings of climate science with these communities.
Along much of the Mid-Atlantic coast, sea levels are rising faster than the global average. This trend has already been linked to intensifying storm surges, shoreline erosion, and the loss of wetlands in the Chesapeake Bay region. To educate residents of Maryland about the impacts of sea level rise and climate change in the Chesapeake region, Maryland Sea Grant formed a unique partnership with the regional news magazine, Bay Journal. This partnership resulted in a special issue of Maryland Sea Grant’s magazine, Chesapeake Quarterly, that was published in October 2014 and titled “Come High Water: Sea Level Rise and Chesapeake Bay.”
Woods Hole Sea Grant funded a climate adaptation project designed to provide regional and local predictions of future coastal storm activity and sea-level rise to user groups within the region and to promote wise utilization and conservation of resources.
Assessing vulnerability to sea level rise in Beaufort County, S.C., using facilitated dialogue and visualization tools
The S.C. Sea Grant Consortium, in partnership with the Beaufort County Planning Department, Carolinas Integrated Sciences and Assessments program, Social and Environmental Research Institute, and North Carolina Sea Grant, provided a participatory opportunity for Beaufort County to begin preparing for flooding associated with sea level rise. The project team utilized several available tools to engage local stakeholders in the process. A focus group participated in the Vulnerability and Consequences Adaptation Planning Scenarios process to identify local consequences of sea level rise and explore potential adaptation strategies. Sea level rise visualizations developed with data from NOAA’s Digital Coast Sea Level Rise Viewer tool helped stakeholders understand the risks of future coastal flooding due to rising seas. Public workshops were held to get broader input on adaptation strategies. A final report has been compiled for consideration by Beaufort County Council. This project has initiated a process of community learning that will increase the capacity of Beaufort County to adapt to sea level rise.
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.
Washington Sea Grant partnered with the Jamestown S'Klallam Tribe and Adaptation International to develop a set of local sea level rise projections, and sea level scenario maps for the Jamestown S'Klallam community. The assessments are being used to identify priority adaptation actions, tribal areas or resources that are particularly vulnerable to sea level rise, and have also been integrated into community long-term planning. Additionally, Washington Sea Grant is partnering with North Olympic Peninsula Resource Conservation District and Adaptation International on a multi-sector climate change vulnerability assessment and adaptation plan, including sea level rise and coastal flooding projections for coastal communities in Clallam and Jefferson Counties.
Washington Sea Grant, working with the Puget Sound Partnership and Puget Sound Ecosystem Monitoring Program Nearshore Work Group, has standardized approaches for monitoring and a “toolbox” of protocols and information. The toolbox emphasizes methods that are simple and affordable, and that can be used for monitoring restoration sites and evaluating status and trends.
Washington Sea Grant, in collaboration with the Climate Impacts Group and the Department of Ecology offered a course through the Padilla Bay NERR’s Coastal Training Program on sea level rise adaptation. Building on the 2008 basic climate change course, this sea level rise course offered up to date scientific projections on sea level rise rates in the Padilla Bay NERR, in addition to methods to effectively communicate climate change, various planning opportunities in Washington, and examples of what others around the US have done. This course is the second in a series of climate adaptation courses.
This was developed through a mid-Atlantic Sea Level Rise project we secured from Coastal Services Center (CSC). It was applied in Annapolis, and they explored its application in Hampton Roads, but it was too early in the evolution of the issues in Hampton Roads to use here. That is, this tool shows climate impacts at the individual lot level and the Hampton Roads citizenry and local elected officials were not ready to see, hear, realize that then (~2011). We are ready now and because we took an incremental approach with our community, we have been able to leap frog some of the challenges that other states faced and Fall 2014 we held a workshop with the real estate community.
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.
