Acadia National Park in Maine is working to rehabilitate historic road systems and culverts that have been damaged by increasingly frequent flooding and erosion events that were causing maintenance and visitor use closures.
The large-scale project known as the Mississippi Coastal Improvements Program (MsCIP) is intended to restore multiple barrier islands and protect cultural resources within Gulf Islands National Seashore by recreating sediment transport processes and replacing a portion of sediment lost to dredging and storm impacts.
Point Reyes National Seashore developed the Giacomini Wetland Restoration Project to restore tidal wetlands from diked agricultural lands. Restoration efforts were accomplished through subgoals to engage the public, manage public access, protect pre- and post-project habitats for multiple listed species, build in resilience to accommodate for potential climate change effects, and adaptively monitor effectiveness of management actions.
Gateway National Recreation Area partnered with other state and federal agencies to restore wetlands in Jamaica Bay, a eutrophic urban estuary, through sediment addition and plantings. While the project was not driven by climate change concerns, addressing marsh elevation loss is consistent with methods to address sea level rise.
Climate change impacts, including coastal erosion, reduction in sea ice, and thawing of permafrost, are impacting Bering Land Bridge National Preserve (BELA) and Cape Krusenstern National Monument (CAKR) along the northwestern Alaska coast. The parks need baseline information and an updated evaluation of coastal resource vulnerabilities in order to make prudent management decisions related to increased marine traffic, sensitive areas, and natural and cultural resource protection.
Ongoing erosion threatened the base of a historic lighthouse at Cape Hatteras National Seashore, despite multiple hard stabilization protection efforts. The park needed to obtain funding and public support to relocate the lighthouse away from the eroding shoreline.
Climate change has increased the vulnerability of cultural resources in coastal locations at Bering Land Bridge National Preserve and Cape Krusenstern National Monument along the northwestern Alaska coast. The Alaska Regional Office is developing and testing a GIS model that is intended to predict locations and vulnerability of these cultural resources.
Canaveral National Seashore contains several of the largest, most intact, and most significant prehistoric shell mounds in North America. Four of these mounds are threatened by erosion induced by sea level rise and increased storm activities.
Incorporating warming disturbances into the design of marine protected areas (MPAs) is fundamental to developing appropriate conservation actions that confer coral reef resilience. We propose an MPA design approach that includes spatially- and temporally-varying sea-surface temperature (SST) data, integrating both observed (1985–2009) and projected (2010–2099) time-series. We derived indices of acute (time under reduced ecosystem function following short-term events) and chronic thermal stress (rate of warming) and combined them to delineate thermal-stress regimes.
The climate has changed and communities across America are living with the consequences: rapid sea level rise, multi-state wildfires, heat waves, and enduring drought. Living with Climate Change: How Communities Are Surviving and Thriving in a Changing Climate details the steps cities are taking now to protect lives and businesses, to reduce their vulnerability, and to adapt and make themselves more resilient.
