Climate change is widely acknowledged to have a profound effect on the biosphere and cryosphere with many and diverse impacts on global resources. Mountain ecosystems in the western U.S., and the U.S. Northern Rocky Mountains in particular, are highly sensitive to climate change. Warming in western Montana is nearly 2 times greater than the rise in global temperatures over the last 100+ years (Pederson et al, 2010). In these mountainous areas, snowmelt provides almost 70% of the water that humans living in the western U.S. depend on (Li et. Al 2017). Additionally, they provide a host of other ecosystem services such as snow-based recreation, timber, habitat for unique flora and fauna, as well as habitat for species of conservation concern like bull trout and grizzly bear. USGS scientists with the Climate Change in Mountain Ecosystems (CCME) group, in conjunction with collaborators across the globe, study the connection between climate and snow on the landscape. Since 1991, studies of climate variability on glaciers, avalanche cycles, and patterns of snow distribution have provided land managers with data to make management decisions for future generations.
Glacier Research
Scientists are studying the park’s receding glaciers to examine the mechanisms of change and assess their ecological and hydrological effects using aerial photography, remote sensing, and field measurements.
Snow and Avalanche Research
Snow avalanche research contributes to our understanding of climate variability and its effect on snowpack and natural avalanche cycles. Evaluation of snowpack characteristics continue to refine our understanding of wet snow avalanches.
Alpine Vegetation Research
The USGS provides oversight of plant inventories in Glacier National Park that contribute to global biodiversity monitoring through partnership with Global Observation Research Initiative in Alpine Environments network.

What are the impacts of glacier loss, other than losing an aesthetic landscape feature?
Glaciers act as reservoirs of water that persist through summer. Continual melt from glaciers contributes water to the ecosystem throughout dry months, creating perennial stream habitat and a water source for plants and animals. The cold runoff from glaciers also affects downstream water temperatures. Many aquatic species in mountainous environments require cold water temperatures to survive. Some...

Climate change links fate of glaciers and rare alpine stream invertebrates in Glacier National Park
The extensive loss of glaciers in Glacier National Park (GNP) is iconic of the global impacts of climate warming in mountain ecosystems. However, little is known about how climate change may threaten alpine stream species, especially invertebrates, persisting below disappearing snow and ice masses in GNP. Two alpine stream invertebrates – the meltwater stonefly and the glacier stonefly – are...Glaciers—Understanding Climate Drivers
Across the globe, glaciers are decreasing in volume and number in response to climate change. Glaciers are important for agriculture, hydropower, recreation, tourism, and biological communities. Loss of glaciers contributes to sea-level rise, creates environmental hazards and can alter aquatic habitats. These are among the cascading effects linked to glacier loss which impact ecosystems and human...Science in Glacier National Park
Glacier National Park (GNP) is considered a stronghold for a large diversity of plant and animal species and harbors some of the last remaining populations of threatened and endangered species such as grizzly bear and bull trout, as well as non threatened keystone species such as bighorn sheep and black bear. The mountain ecosystems of GNP that support these species are dynamic and influenced by...Going-to-the-Sun Road Avalanche Forecasting Program
As the most popular attraction in Glacier National Park (GNP), the Going-to-the-Sun Road traverses scenic alpine zones and crosses the Continental Divide at Logan Pass (2026m or 6,647' elevation). The Park closes a 56km (34.8 mile) section of the road each winter due to inclement weather, heavy snowfall, and avalanche hazards. Annual spring opening of the road is a highly anticipated event for...Repeat Photography Project
Repeat photography provides objective visual evidence of landscape change. USGS scientists created approximately sixty repeat photography pairs that document glacier change in Glacier National Park. These photograph pairs are available as a collection hosted by the USGS Photographic Library and are publicly available for download. Modern (1997 to 2019) photographs were taken from precisely the...Status of Glaciers in Glacier National Park
Glaciers on the Glacier National Park (GNP) landscape have ecological value as a source of cold meltwater in the otherwise dry late summer months, and aesthetic value as the park’s namesake features. USGS scientists have studied these glaciers since the late 1800s, building a body of research that documents widespread glacier change over the past century. Ongoing USGS research pairs long-term data...Integrated bioassessment of imperiled alpine aquatic ecosystems using NPS vital signs and USGS research data: Implications for conservation under a warming climate
Climate warming in the mid- to high-latitudes and high-elevation mountainous regions is occurring more rapidly than anywhere else on Earth, causing extensive loss of glaciers and snowpack. The loss of glaciers in Glacier National Park (GNP) is iconic of the combined impacts of global warming and reduced snowpack−all remaining 25 glaciers are predicted to disappear by 2030. These changes will... - Data
