Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown

Understanding a changing world and how it affects our natural resources, livelihoods, and communities. Science plays an essential role in helping communities and resource managers understand the local to global implications of change, anticipate the effects of change, prepare for change, and reduce the risks associated with decisionmaking in a changing environment.

Data and Tools
Land Resources supports the science community with its long-term observational networks and extensive databases encompassing the fields of climate history, land-use and land-cover change, and carbon and nutrient cycles.
Whether fully or in part, the Earth Resources Observation and Science (EROS) Center’s fingerprints are all over the National Climate Assessment (NCA) and associated reports that have been released since passage of the U.S. Global Change Research Act of 1990.
The American Geophysical Union’s Fall Meeting takes place Dec. 10-14 in Washington, D.C. The work of the USGS Earth Resources Observation and Science (EROS) Center will be well-represented at the weeklong conference. More than half a dozen USGS EROS researchers will lead or participate in sessions, and EROS authors contributed to many others....
When a wildfire rampages through a sagebrush domain, restoring the landscape’s natural vegetation afterward is often a dicey proposition. But now complicate that situation with soil-moisture-robbing drought either before or after the fire. What becomes the best restoration solution then?
Chapter 2: Climate, disturbance, and vulnerability to vegetation change in the Northwest Forest Plan Area
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...Reilly, Matthew J.; Spies, Thomas A.; Littell, Jeremy S.; Butz, Ramona J.; Kim, John B.
Climate Change in Port Heiden, Alaska - Strategies for Community Health
There are two components to this document. The first component is the scope of described environmental change and its impacts in Port Heiden Alaska. The second component is a list of priorities to be addressed that will help Port Heiden achieve its vision for the future. Each priority area incorporates local knowledge with available climate...Lujan, Erica; Brubaker, Mike; Warren, John; Christensen, Jaclyn; Anderson, Scott; O'Domin, Melissa; Littell, Jeremy S.; Buzard, Richard M.; Overbeck, Jacquelyn R.; Holen, Davin; Flensburg, Sue; Powers, Elizabeth
Drought and fire in the western USA: Is climate attribution enough?
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.
