Extreme Weather

Global changes in temperature and precipitation are reflected in local weather patterns in ways both mundane (e.g., warmer winter days) and extreme (e.g., more severe hurricanes). Changes in the frequency and severity of extreme weather events such as hurricanes, blizzards, and floods can devastate human and ecological communities and fundamentally shift ecosystem and water dynamics in the region. The CASC network produces knowledge, data, and tools to understand and predict extreme weather events and help develop strategies for protecting communities and ecosystems.

Assessing Direct and Indirect Effects of Climate on Wild Turkeys Across the Southeastern U.S.

Wild turkey is a culturally and economically important game species that has shown dramatic population declines throughout much of the southeastern U.S. A possible explanation for these declines is that the timing of nesting has shifted to earlier in the year while hunting seasons have remained the same. Wild turkeys are the only gamebird in the contiguous United States that are hunted during the

A Decision Support System for Estimating Changes in Extreme Floods and Droughts in the Northeast U.S.

Floods and droughts are forecasted to occur with greater frequency and to be more extreme because of climate change. These changes will increase stresses on both cities and natural systems. Increased flooding can harm infrastructure designed to support human needs and natural systems that support fish and wildlife. Increased drought can have direct impacts on fish and wildlife by increasing river

Generating a Shoreline Inventory for Hawai‘i Island to Increase Resilience in the Face of Rising Sea Levels

Globally, shorelines provide a vital defense system against extreme weather and erosion events and are a critical public and cultural resource. Within the state of Hawaiʻi, coastal vulnerability and historic change has been well documented and studied on the Islands of Oʻahu, Maui, and Kauaʻi, but this has not been done for the Island of Hawaiʻi, the largest and most diverse island in the Hawaiian...

Preliminary Investigation of Machine Learning Approaches to Improve Projections of Future Climate in Hawai‘i

Detailed, reliable projections of future changes in climate are needed by Hawai‘i’s resource managers, such as water utilities managers, land managers, conservation organizations, and decision makers. However, global climate models (or “general circulation models”), which are currently the most commonly used tool for projecting future climate variations, are known for representing large-scale clim...

Dynamic Climate Adaptation for Wetland Restoration and Coastal Communities on Lake Ontario

Residents living along the coast of Lake Ontario and the St. Lawrence River have experienced two record-setting floods, one in 2017 and another in 2019. These floods caused tremendous property damage and disruptions to the regional economy. The water levels on Lake Ontario are influenced by the operations of the Moses Saunders Dam on the St. Lawrence River. These operations are determined by the I

Designing Climate-Resilient Habitat for At-Risk Species in the Southern Sierra Nevada Forest

Climate change adaptation research has made major advances over the last decade. For example, much is known about the impacts of climate change, many novel adaptation planning approaches have been developed, decision tools have become ubiquitous, and many novel adaptation options have been proposed. However, additional research is needed to demonstrate how these adaptation planning schemes can tra

Adapting to Climate Change: Trends and Severe Storm Responses by Migratory Landbirds and Their Habitats

Over two-thirds of all landbirds (i.e. birds that spend the majority of their lives in terrestrial environments) in North America migrate long-distances to areas in Mexico, Central and South America and the Caribbean islands. Habitats within Texas and Louisiana support high numbers of birds when they interrupt their migratory journeys through the Gulf of Mexico region to “stopover” for resting and...

Learning From the Past and Planning for the Future: Experience-Driven Insight Into Managing for Ecosystem Transformations Induced by Drought and Wildfire

Drought and wildfire pose enormous threats to the integrity of natural resources that land managers are charged with protecting. Recent observations and modeling forecasts indicate that these stressors will likely produce catastrophic ecosystem transformations, or abrupt changes in the condition of plants, wildlife, and their habitats, in regions across the country in coming decades.
