Climate change poses significant risks to coasts, from sea level rise and high-tide flooding to accelerated erosion and intensifying storms. USGS scientists help coastal communities better understand climate change impacts, inform emergency responses, and provide insights to improve resilience and preserve coastal resources in the future.
How does Climate Change Affect U.S. Coasts?
Millions of Americans live and play along the coast. Coastal counties are home to 127 million people (and growing!), accounting for $8.6 trillion in goods and services each year. Coastal communities are well acquainted with the realities of living by the ocean – the storms, the waves, the salt, the sand. Yet climate change is altering the Nation’s coastal landscapes, creating new challenges for these communities that they are seldom equipped to face.

USGS Helps Communities Understand New Coastal Hazards
By helping people understand and respond to coastal change, the USGS helps communities become resilient to coastal hazards now and in the future.
USGS researchers use on-the-ground field work, high-resolution data, and modeling to help communities understand and respond to changes in coastal landscapes. Federal, Tribal, state, and local offices around the country use USGS data to inform coastal management and strategic planning. Some use our science to plan evacuation notices, inform city planning, and construct storm-resistant infrastructure. Others use USGS habitat assessments and decision support tools to restore coastal ecosystems, developing “green infrastructure” that can buffer against future storm damage and coastal erosion.
Our science helps to:
-
Forecast future storms, floods, and coastal erosion, and predict the resulting impacts on coasts
-
Build a better understanding of coastal ecosystems
-
Understand climate change impacts to coastal ecosystems and communities
-
Develop decision support tools to help coastal communities prepare for and recover from storms, floods, and erosion
-
Restore and protect coastal ecosystems that absorb greenhouse gasses, reducing the effects of climate change (blue carbon)

Coastal Climate Impacts
The impacts of climate change and sea-level rise around the Pacific and Arctic Oceans can vary tremendously.

Furthermore, the degree to which extreme waves and wind will add further stress to coastal...

USGS Coastal Change Hazards
The USGS Coastal Change Hazards team works to identify and address the Nation’s coastal change hazards problems. By integrating research, technical capabilities and applications, and stakeholder engagement and communications, the Coastal Change Hazards team develops robust and accessible coastal change assessments, forecasts, and tools that help improve the lives,

Studying How the Beach Changes at Madeira Beach, Florida
The importance of our Nation’s coasts is indisputable. They provide homes for people and animals alike, and support the Nation’s economy. The USGS Coastal Change Hazards team studies how our shorelines change over time, especially following extreme events such as storms and hurricanes.

Eyes on Earth Episode 25 - Rising Seas
Sea levels are rising globally. In some places, it is rising more than others, threatening communities and people as storm surges reach further inland and inundate more land.

Sea-Level Rise, El Niño, and Storm Effects on Coastal Tidal Marshes
Tidal marshes exist as a transitional environment between the land and sea, and provides habitat to fish and wildlife, protects human developments from coastal flooding, and stores carbon at high density, among other important ecosystem services.

Juvenile Mangroves on Jim Foot Key, Florida
In Photo: Juvenile mangroves on eastern berm of Jim Foot Key, April 2019. Mangroves are intermingled with saltwort, the dominant live vegetation on the damaged berms, and standing dead mangroves. Grid is 25 cm high. The question is whether these trees will mature fast enough to protect the berm from rising sea level.

Dauphin Island, Alabama
A view of a vegetated inland coastline overlooking the water on Dauphin Island, Alabama. The island protects mainland Alabama’s coastal communities and resources from storms, while also providing recreational opportunities (fishing, beach tourism, etc.) and other economic benefits to the local community and state.

Healthy elkhorn coral on the seafloor in the U.S. Virgin Islands
Healthy elkhorn coral (Acropora palmata) on the seafloor along the southeastern coast of Buck Island, U.S. Virgin Islands. Elkhorn coral is one of many important reef-building species that create 3D structure on the seafloor. Coral reef structure provides habitat for marine life and helps break up waves as they approach the coastline.
