Effect of Extreme Tidal Events on Future Sea-Level Rise Scenarios for He‘eia Fish Communities undergoing Ahupua‘a Restoration

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.

Estimating Future High-Mountain Snowpack to Inform Terrestrial and Aquatic Species Status Assessments, Recovery Plans, and Monitoring

One of the most visible signs of climate change is less mountain snow. In the Western U.S., deep snow has historically been a cornerstone of life for many plants and animals. For example, snow can provide denning shelter for certain species like the wolverine, and snowmelt provides dependable water to mountain streams that are home to fish like the bull trout. Yet snow losses driven by warming tem

Estimating the Future Effects of Forest Disturbance on Snow Water Resources in a Changing Environment

In the Western U.S., approximately 65% of the water supply comes from forested regions with most of the water that feeds local rivers coming from snowmelt that originates in mountain forests. The Rio Grande headwaters (I.e. the primary water generating region of the Rio Grande river) is experiencing large changes to the landscape primarily from forest fires and bark beetle infestations.

Future Changes in Snow Avalanches in Southern Alaska

Ongoing climate change is impacting areas of snow and ice in high latitudes and high elevation areas and is thus anticipated to change the frequency and magnitude of snow and ice related hazards. In Alaska, snow avalanches are the deadliest natural hazard, and they affect a large portion of the state, significantly impacting the natural landscape, the built environment, and public safety.

Indigenous-Led Climate Adaptation Strategies: Integrating Landscape Condition, Monitoring, and Cultural Fire with the North Fork Mono Tribe

Indigenous peoples and nations are on the front lines of climate change impacts and are leading the way in innovative adaptation action, such as in the use of traditional burning. Traditional burning has been recognized as a robust adaptation strategy, increasing the resiliency of ecosystems and the local communities that depend on them for their economic and social well-being.

Landscape Management Practices on the Pueblo de San Ildefonso

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

Linking Models to Outcomes – How do Hawaiʻi Stakeholders Use and Contribute to Land-to-Sea Ecosystem Service Analyses

Pacific Island societies value, depend on, and actively manage terrestrial and marine ecosystems for the multiple benefits they provide, including those associated with plant and animal abundance, resilience to natural disasters, and the flow of water, soil, and nutrients. New ecosystem service models developed for Pacific Island landscapes now integrate land-to-sea connections, allowing us to ass

Using Precipitation Climatology to Examine the Role of Climate Change in Extreme Events of the Mississippi River Basin

The greater Mississippi River Basin drains 3.2 million square kilometers of land and spans 31 U.S. states. Ninety percent of all U.S. agricultural exports are grown in the Mississippi River Basin, and about 40 percent of the nation's total exports are transported through its major rivers. About 1.3 million people, accounting for $405 billion in annual revenues, work in river-related jobs across th

Where the Creek Meets the Tide: Effects of Climate Change on Salmon, Homes, and Businesses, and the Squaxin Island Tribe

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 significant impac

A Climate-Informed Adaptation and Post-Fire Strategy for the Southwestern Region

The Southwest is projected to face significant climate challenges in coming decades; and many of these stresses have already begun. In recent years, multiple climate assessments have been developed for the Southwest that corroborate forecasts of remarkable change to vegetation pattern and the vulnerability of regional ecosystems and suggest that measurable change is already ongoing.
