Future climate conditions in the Upper Mississippi River Basin are projected to include many more extreme precipitation events. These intense periods of rain can lead to flooding of the Mississippi River itself, as well the small streams and rivers that feed it. This flooding presents a challenge for local communities, farmers, small businesses, river users, and the ecosystems and wildlife in the area. To reduce the damage done by these extreme rainfall events, ‘natural solutions’ are often helpful. This might include preserving forests and grasslands to absorb rainwater before it arrives at streams or restoring wetlands to slow and clean runoff water. For river and natural resource managers to adapt to future climate...

The Midwest has experienced some of the costliest flooding events in U.S. history, including many billions of dollars during the past decade alone. The Midwest’s susceptibility to flooding has been exacerbated by a long-term increase in total precipitation and extreme rainfalls, with the 2010s being the region’s wettest decade on record Climate models strongly indicate that these recent trends will continue, such that the warming Midwest will experience wetter winters and springs, shortened snow seasons, and extreme year-round precipitation in the future. Despite this high level of confidence in climate trends, there is limited knowledge of how these will translate to flood likelihood and the associated societal...

The 2017 fire season in California was highly unusual with its late seasonal timing, the areal extent it burned, and its devastation to communities. These fires were associated with extreme winds and were potentially also influenced by unusually dry conditions during several years leading up to the 2017 events. This fire season brought additional attention and emphasized the vital need for managers in the western U.S. to have access to scientific information on when and where to expect dangerous fire events. Understanding the multiple factors that cause extreme wildfire events is critical to short and long-term forecasting and planning. Seasonal climate measures such as temperature and precipitation are commonly...

National Wildlife Refuges (NWRs) along the East Coast of the United States protect habitat for a host of wildlife species, while also offering storm surge protection, improving water quality, supporting nurseries for commercially important fish and shellfish, and providing recreation opportunities for coastal communities. Yet in the last century, coastal ecosystems in the eastern U.S. have been severely altered by human development activities as well as sea-level rise and more frequent extreme events related to climate change. These influences threaten the ability of NWRs to protect our nation’s natural resources and to sustain their many beneficial services. Through this project, researchers are collaborating with...

In the northern Gulf of Mexico, mangrove forests have been expanding their northern range limits in parts of Texas, Louisiana, and north Florida since 1989. In response to warming winter temperatures, mangroves, which are dominant in warmer climates, are expected to continue migrating northward at the expense of salt marshes, which fare better in cooler climates. The ecological implications and timing of mangrove expansion is not well understood, and coastal wetland managers need information and tools that will enable them to identify and forecast the ecological impacts of this shift from salt marsh to mangrove-dominated coastal ecosystems. To address this need, researchers will host workshops and leverage existing...

The Pacific Ocean is home to a number of low-lying, coastal national parks and wildlife refuges. These public lands are situated on coral reef-lined islands that are susceptible to inundation from sea-level rise and flooding during storms. Because of their low-lying nature and limited availability of space, ecosystems, cultural resources, and infrastructure on these islands are particularly vulnerable to flooding. Sea-level rise will further exacerbate the impact of storms on island parks and refuges by increasing wave-driven coastal flooding, with consequences for ecological and human communities alike. However, most assessments of future conditions at coastal national parks and refuges consider only permanent...

California - one of the nation's most populous states - hosts extensive public lands, crown-jewel national parks, and diverse natural resources. Resource managers in federal, state, tribal, and local agencies face challenges due to environmental changes and extreme events such as severe droughts, heat waves, flood events, massive wildfires, and forest dieback. However, state-of-the-art research that could aid in the management of natural resources facing these challenges is typically slow to be applied, owing to limited time and capacity on the part of both researchers and managers. This project aims to accelerate the application of science to resource management by facilitating the translation and synthesis of...

A large portion of the U.S. population lives in coastal areas along the Atlantic and Gulf coasts and the Caribbean; however, our coasts are also home to many fish, wildlife, and plant species that are important for recreation, tourism, local economies, biodiversity, and healthy coastal ecosystems. Coastal habitats also provide protective ecosystem services to human communities, which are increasingly at risk to storms and sea level rise under future climate change. Understanding how climate change will impact natural and human communities is a crucial part of decision making and management related to the protection of our coasts. In a collaborative project between the North Atlantic Landscape Conservation Cooperative...

Climate and land use change will strongly affect tropical island ecosystems and trust species (like migratory birds and threatened and endangered species). The risks of significant negative impacts are likely to be higher in these island systems than in many temperate regions of the world because of the limited size of their land masses, high numbers of species that only exist in narrowly defined regions, and expectations that tropical environments will experience greater changes in temperature. Tropical island communities are faced with making important decisions related to adaptation that could impact the health of important natural resources and ecosystems. However, a lack of scientific guidance and information...
A new satellite-derived low cloud retrieval reveals rich spatial texture and coherent space-time propagation in summertime California coastal low cloudiness (CLC). Throughout the region, CLC is greatest during May–September but has considerable monthly variability within this summer season. On average, June is cloudiest along the coast of southern California and northern Baja, Mexico, while July is cloudiest along northern California's coast. Over the course of the summer, the core of peak CLC migrates northward along coastal California, reaching its northernmost extent in late July/early August, then recedes while weakening. The timing and movement of the CLC climatological structure is related to the summer evolution...

In recent decades, average temperatures across the U.S. Southwest have increased substantially and precipitation patterns have increased in variability. The warmer temperatures directly impact water availability within Southwest ecosystems, including earlier snowmelts; reduced snowpacks, soil moisture, and streamflow; and lower humidity. Collectively, this has led to an increase in aridity across this region. This in turn affects terrestrial and aquatic ecosystems, increases wildfire severity, and impacts human activities such as agriculture and municipal water use. These well-documented trends are at the forefront of the concerns of natural resource managers in the Southwest. This project aims to strengthen partnerships...

The Pueblo de San Ildefonso is facing increased wildfire risk under climate change. Recent fires have not only burned culturally significant sites, but they have also resulted in a loss of watershed runoff retention, which has increased erosion and the transport of contaminated sediments and soils on Pueblo lands from the adjacent Los Alamos National Laboratory (LANL). A priority for the Pueblo is to ensure that wildfires are managed appropriately and, when large fires do occur, that effective measures are taken to control the aftermath of increased flooding and erosion. This project will build on the knowledge of elders and the community to develop a study plan (or study method) to evaluate different landscape...

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 reproductive season, so premature harvest of adult male turkeys may disrupt reproductive behaviors and reduce population growth. In addition to hunter harvest, climate change can also impact population growth of wild turkeys. Local and broad-scale regional changes in precipitation and temperature associated with a changing...

In California, the near-shore area where the ocean meets the land is a highly productive yet sensitive region that supports a wealth of wildlife, including several native bird species. These saltmarshes, mudflats, and shallow bays are not only critical for wildlife, but they also provide economic and recreational benefits to local communities. Today, sea-level rise, more frequent and stronger storms, saltwater intrusion, and warming water temperatures are among the threats that are altering these important habitats. To support future planning and conservation of California’s near-shore habitats, researchers examined current weather patterns, elevations, tides, and sediments at these sites to see how they affect...

The Salt and Verde river basins in northeastern Arizona are a vital source of fresh water for the greater Phoenix metropolitan area and for two Native American tribes who rely on the basins’ natural resources for their livelihoods. The region depends on winter rain and snow to replenish the river basins’ water supply. Atmospheric rivers – long, narrow channels in the atmosphere that carry water vapor from the Pacific Ocean – supply a substantial portion of this winter precipitation. While atmospheric rivers are critical for maintaining water resources and preventing drought, they occasionally cause extreme storms that lead to flooding. Scientists project that climate change will affect the intensity and frequency...

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 will develop a comprehensive dataset and create a prioritization plan for coastal wetland restoration. The team will work closely with project partners and stakeholders to develop a well-vetted plan to support endangered species and meeting community needs. Existing maps and spatial data about the Molokaʻi landscape will be compiled...

Barrier islands are exposed to a range of natural and human-caused changes, including hurricanes, sea-level rise, and dredging. These changes have the potential to influence the ability of barrier islands to serve as a first-line of defense for the mainland during storm events. Gulf Islands National Seashore, a National Park Service unit in the northern Gulf of Mexico between Florida and Mississippi, is predominantly comprised of barrier islands and faces immediate challenges, including erosion that washes out roads and sand dunes and the adverse impacts on cultural and natural resources from exposure to saltwater. Managers require realistic estimates of both the vulnerability of the park’s natural and cultural...
