Climate and Land Use science is essential to improve understanding of past and present change; develop relevant forecasts; and identify those lands, resources, and communities most vulnerable to Earth system change processes.Our Science Strategy
When it comes to hurricanes, wind and storm surge effect vegetation differently. USGS anlyzes these differences following Hurricane Sandy to help inform management on storm mitigation and long-term planning.
Understanding systems sometimes requires approaches that allow for both the discovery of the a system's structure and the estimation of its implications. Structural Equation Modeling - SEM - is one tool scientists use to better understand the complex world in which we live.

Wetlands vary in their abilities to keep up with sea-level rise; they either adjust vertically and/or move inland. USGS is working with partners around the world to measure rates of surface elevation change relative to local sea-level rise.
Climate change research in Glacier National Park, Montana entails many methods of documenting the landscape change, including the decline of the parks namesake glaciers. While less quantitative than other high-tech methods of recording glacial mass, depth, and rate of retreat, repeat photography has become a valuable tool for communicating effects of global warming. With evidence of worldwide...
Worldwide glacial glacier recession is well documented (1,2) and varied model projections suggest that certain studied GNP glaciers will disappear in the next few decades, between 2030 (3) to 2080 (4). USGS scientists in Glacier National Park are collaborating with glaciologist from Alaska and Washington and using...
Glacier National Park is a topographically diverse region, making localized effects of elevation, aspect, and cold air drainage several of many important factors that necessitate a diversity of long-term climate monitoring sites. Additionally, many studies have shown more rapid warming at higher elevations across the Intermountain West, but with relatively few high-elevation stations available...
Repeat photography is being used by the CCME program to document landscape change. Glaciers have been the primary focus of this park-wide survey and this collection of repeat photographs, available for download on the CCME website, have been used to illustrate the effects of climate change in venues across the globe. These powerful images, with their inherent ease of interpretation, have...
Since 1991, CCME staff have conducted snow surveys throughout Glacier National Park. These data have contributed to regional climate change and hydrologic models. Snowpack characteristics have also been evaluated in relation to avalanche forecasting and plowing of GNP’s Going to the Sun Road efforts. Studies of natural snow avalanches reveal connections with large-scale climate and wildfire...
The Secondary Glacier Network includes six glaciers (Chaney, Grinnell, Stanton, Agassiz, Swiftcurrent, Jackson-Blackfoot Glaciers) that form a north-south transect of approx. 60 km through the region, with Sperry Glacier just south of center. While these glaciers will be monitored less frequently than the benchmark glacier, Sperry, this network will provide data about the variability of...
Sperry Glacier was chosen as the benchmark glacier for the glacier monitoring studies, due to the combination of its topographic characteristics, historic data, and access. Annual mass balance measurements began in 2005. Sperry Glacier joined the long-established USGS Benchmark Glacier Research program in 2013 where common field and analysis methods enable regional comparison and improved...
The purpose of the CCME's glacier monitoring studies is to systematically monitor changes in Glacier National Park’s namesake glaciers and to determine the causes of changes, assess their ecological and hydrological effects, and predict future changes and effects.

The Interior Department’s Climate Science Centers, managed by USGS, are helping the NPS pinpoint the specific impacts of climate change on parks and their cultural and natural resources. Doing so will help managers answer a critical question: which resources will require human intervention to ensure their continued existence?
