Sea Level Rise

Coastal flooding and erosion caused by storms and sea-level rise threaten infrastructure and public safety in Alaska Native communities. Though the problem is well known, there are few tools that can assess local vulnerability to coastal flood hazards. Even fewer tools can be customized with specific community information to support local adaptation planning. The main goal of this...

Continued sea-level rise from a changing climate is expected to result in the loss of many coastal mangrove trees, which, will strongly affect human populations on isolated Western Pacific islands as they rely heavily on mangrove forests for food (fish, shrimp, and crabs), building materials, and firewood. Mangroves also protect local communities from tsunamis and cyclones and are...

Salt marshes are grassy wetlands that form along sheltered coastlines. These areas provide crucial habitats for many species of birds and other animals, in addition to recreational activities and economic opportunities. Marshes also protect the coast from storms and filter runoff from the landscape, ensuring cleaner and healthier coastal waters. As climate change causes sea levels to...

This project seeks to enhance the stewardship of historic buildings vulnerable to climate change impacts. As sea level rise and storm-related flooding and erosion threaten our nation’s cultural heritage, there is a critical need to ensure that climate change adaptation decisions, including what cultural resources will be “let go”, are transparent and informed by the opinion of people...

One of the largest and most expensive restoration efforts in the world is the restoration of the Everglades, a sub-tropical freshwater wetland system located in southern Florida. This unique ecosystem supports several endemic and endangered species, provides flood control for Florida’s large urban population, and provides water for both the agricultural and drinking supply within the...

Coastal resource and infrastructure managers face rapidly mounting environmental challenges. Increases in sea levels, decaying or outdated infrastructure, compound flooding from ocean storm surges and river runoff, and temperature and moisture extremes are all increasing the vulnerability of natural habitats, public, private, and commercial infrastructure, and community health and...

Since the 1930s, Louisiana has lost approximately 1,900 mi2 of land due to coastal erosion, land subsidence, and sea-level rise exacerbated by climate change, putting Native American archaeological sites along Louisiana’s Gulf Coast in danger of being destroyed. These cultural resources are crucial sources of information and represent the unique heritage of coastal Louisiana. Federal and...

Moloka‘i has great wetland restoration potential in Hawaiʻi, but most remaining sites are highly degraded. The future of several endangered waterbirds and insects relies on restoring coastal wetland habitat that is resilient under sea-level rise and coastal flooding. Currently, managers lack background data on Molokaʻi to prioritize sites for restoration. In this project, researchers...

For the past few years, “king tides,” or the highest tides of the year, have been occurring more frequently and significantly affecting coastal environments across Hawaiʻi. Now, disappearing beaches and waves crashing over roadways are seemingly the “new normal.” In response, the state of Hawaiʻi is implementing adaptation strategies to combat tidal flooding in coastal areas. While flood

The combined effects of climate change (e.g. increased freshwater supply, sea level rise, etc.), leveeing of the Mississippi River, and the gradual settling of soil have led to a land loss crisis in coastal Louisiana. Coastal wetlands provide various ecosystem services to local coastal communities, such as storm protection, flood control, and habitat for economically and ecologically...

The Squaxin Island Tribe (SIT) is descended from maritime people who have lived and prospered along the shores of the southernmost inlets of the Salish Sea for millennia. Climate change is projected to result in lower low water flows, higher peak water temperatures, and bigger and more frequent floods, due to both changes in peak flows and sea level rise. These changes could have...

Madagascar, a country rich in natural capital and biodiversity but with high levels of poverty, food insecurity, and population growth, faces a number of development challenges, including obtaining sustained financial support from external sources and building internal capacity to address the poor environmental, health, and socio-economic conditions. Climate change poses an increasing...
