Water, Coasts and Ice

Warming temperatures and shifting weather patterns are causing major changes in water and ice availability, sea levels, and aquatic nutrient cycles across the country. CASC-supported scientists are examining how water, ice, and coastal ecosystems and communities across the country are being affected by climate change. Explore our science on this topic below.

Understanding and Communicating the Role of Natural Climate Variability in a Changing World

Natural climate variability can obscure or enhance long-term trends in experienced weather due to climate change. This can happen temporarily on timescales of a season to several years to a decade or two. Natural variability is poorly described and attributed to specific causes, contributing to uncertainty and misunderstandings about the nature of climate change that stakeholders and resource mana

Understanding and Projecting Changes in Climate, Hydrology, and Ecology in the Great Basin for the Next 30 Years

This project links climate, hydrological, and ecological changes over the next 30 years in a Great Basin watershed. In recent years, climate variability on annual and decadal time scales has been recognized as greater than commonly perceived with increasing impacts on ecosystems and available water resources. Changes in vegetation distribution, composition and productivity resulting from climate c

Understanding How Climate and Land Use Change Will Impact Wetland-Dependent Birds: Are Waterfowl Effective Surrogates for Other Species?

The Prairie Pothole Region spans parts of North and South Dakota, Minnesota, Montana, Iowa and south-central Canada and contains millions of wetlands that provide habitat for breeding and migrating birds. Because it is the continent’s most important breeding area for waterfowl, conservation and management largely focuses on protecting habitat for nesting ducks. However, other wetland-dependent bir

Understanding the Nexus between Climate, Streamflow, Water Quality, and Ecology in the Arkansas-Red River Basin

Currently, maintaining appropriate flows to support biological integrity is difficult for larger riverine ecosystems. Climate change, through increased temperature, reduced rainfall, and increased rainfall intensity, is expected to reduce water availability and exacerbate the maintenance of ecological flows in the Arkansas-Red River basin.

Valuing Climate Change Impacts on Coral Reef Ecosystem Services

Coral reefs provide numerous ecosystem goods and services critical to human well-being (e.g., protection from storms and floods, food, income, recreation, and cultural practices), but they are threatened by growing human pressures and climate change. Resource managers must make complex decisions when developing adaptation plans that are cost-effective and maintain coral reef functions while still

Very High Resolution Climate Projections for the Islands of O‘ahu and Kaua‘i

The Hawaiian Islands are home to many people and host a rich diversity of unique plant and animal life, but they are especially vulnerable to the effects of climate change because of their small size, geographical remoteness, and exposure to threats such as sea-level rise and increased storm surge. Developing predictions of future conditions is often the first step in helping decision makers and c

A Handbook for Resource Managers to Understand and Utilize Sea-Level Rise and Coastal Wetland Models

Coastal wetlands and the many beneficial services they provide (e.g., purifying water, buffering storm surge, providing habitat) are changing and disappearing as a result of sea-level rise brought about by climate change. Scientists have developed a wealth of information and resources to predict and aid decision-making related to sea-level rise. However, while some of these resources are easily ac
