Jeremy Littell, Ph.D.
Jeremy Littell is a Research Ecologist (Climate Impacts) with the Department of Interior Alaska Climate Science Center. He conducts research on the role of climate and ecological drought in Alaskan and other forested ecosystems. He also facilitates the use of climate information in planning, adaptation, and vulnerability assessment.
Biography
Littell's background is the ecoclimatology of western North America's forests. His doctoral work at the University of Washington focused on ecological and climatic controls on wildfire in the western U.S. and the role of climate in Douglas-fir tree growth across its climatic range. He also worked as a research scientist at the UW Climate Impacts Group, collaborating with resource managers in Federal and state agencies to better understand and use climate information in planning and adaptation. At the Alaska Climate Science Center, his current work adresses tow main themes:
- Development, coordination, and translation of climate science products for Alaska
- Observing and Understanding the Impacts of climate on Alaskan Forests
He also serves as an author on the Alaska chapter of the National Climate Assessment (NCA).

View this webinar to learn how the Alaska CASC and partners are developing climate adaptation tools for Alaskan communities implementing climate adaptation strategies.
Snowpack signals in North American tree rings
Climate change has contributed to recent declines in mountain snowpack and earlier runoff, which in turn has intensified hydrological droughts in western North America. Climate model projections suggest that continued and severe snowpack reductions are expected over the 21st century, with profound consequences for ecosystems and human welfare. Yet...
Coulthard, Bethany L.; Anchukaitis, Kevin J.; Pederson, Gregory T.; Cook, Edward R; Littell, Jeremy S.; Smith, Dan J.Increased drought severity tracks warming in the United States’ largest river basin
Across the Upper Missouri River Basin, the recent drought of 2000 to 2010, known as the “turn-of-the-century drought,” was likely more severe than any in the instrumental record including the Dust Bowl drought. However, until now, adequate proxy records needed to better understand this event with regard to long-term variability have been lacking....

This report provides an overview of model-based climate science in a risk management context. In addition, it summarizes how the U.S. Geological Survey (USGS) will continue to follow best scientific practices and when and how the results of this research will be delivered to the U.S. Department of the Interior (DOI) and other stakeholders to...
Terando, Adam; Reidmiller, David; Hostetler, Steven W.; Littell, Jeremy S.; Beard, T. Douglas; Weiskopf, Sarah R.; Belnap, Jayne; Plumlee, Geoffrey S.Managing effects of drought and other water resource challenges in Alaska and the Pacific Northwest
This is a Cooperator Report. As such, there is no specific abstract. The physical, ecological, and social environments of Alaska and the Pacific Northwest (PNW) region of the United States are extremely diverse. Alaska ranges from the Arctic Ocean and the very cold, dry environments of the North Slope to the cool and very rainy coastal North...
Halofsky, Jessica E.; Littell, Jeremy S.; Peterson, David L.; Hayward, Gregory D.; Gravenmier, Rebecca1200 years of Upper Missouri River streamflow reconstructed from tree rings
Paleohydrologic records can provide unique, long-term perspectives on streamflow variability and hydroclimate for use in water resource planning. Such long-term records can also play a key role in placing both present day events and projected future conditions into a broader context than that offered by instrumental observations. However,...

Paleohydrologic reconstructions of water-year streamflow for 105 sites across the western United States (West) were used to compute the likelihood (risk) of regime (wet/dry state) shifts given the length of time in a specific regime and for a specified time in the future. The spatial variability of risks was examined and indicates that regime...
Gangopadhyay, Subhrendu; McCabe, Gregory J.; Pederson, Gregory T.; Martin, Justin; Littell, Jeremy S.Alaska
Alaska is the largest state in the Nation, almost one-fifth the size of the combined lower 48 United States, and is rich in natural capital resources. Alaska is often identified as being on the front lines of climate change since it is warming faster than any other state and faces a myriad of issues associated with a changing climate....

Climate change is expected to alter the composition, structure, and function of forested ecosystems in the United States (Vose et al. 2012). Increases in atmospheric concentrations of greenhouse gases (e.g., carbon dioxide [CO2]) and temperature, as well as altered precipitation and disturbance regimes (e.g., fire, insects, pathogens, and...

Purpose of ReviewI sought to review the contributions of recent literature and prior foundational papers to our understanding of drought and fire. In this review, I summarize recent literature on drought and fire in the western USA and discuss research directions that may increase the utility of that body of work for twenty-first century...
Littell, Jeremy S.Downscaling of climate model output for Alaskan stakeholders
The paper summarizes an end-to-end activity connecting the global climate modeling enterprise with users of climate information in Alaska. The effort included retrieval of the requisite observational datasets and model output, a model evaluation and selection procedure, the actual downscaling by the delta method with its...

We developed ecologically based climate‐fire projections for the western United States. Using a finer ecological classification and fire‐relevant climate predictors, we created statistical models linking climate and wildfire area burned for ecosections, which are geographic delineations based on biophysical variables. The results indicate a...
Littell, Jeremy S.; McKenzie, Donald; Wan, Ho Yi; Cushman, Samuel A.Unfamiliar Territory: Emerging Themes for Ecological Drought Research and Management
Novel forms of drought are emerging globally, due to climate change, shifting teleconnection patterns, expanding human water use, and a history of human influence on the environment that increases the probability of transformational ecological impacts.
