Climate Change in Mountain Ecosystems (CCME) Active
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.

Large magnitude snow avalanches play an important role ecologically in terms of wildlife habitat, vegetation diversity, and sediment transport within a watershed. Ecological effects from these infrequent avalanches can last for decades. Understanding the frequency of such large magnitude avalanches is also critical to avalanche forecasting for the Going-to-the-Sun Road (GTSR). In January 2009, a lAuthorsDaniel B. Fagre, Erich H.

Potential economic impacts of future climate change on crop enterprise net returns and annual net farm income (NFI) are evaluated for small and large representative farms in Flathead Valley in Northwest Montana. Crop enterprise net returns and NFI in an historical climate period (1960–2005) and future climate period (2006–2050) are compared when agricultural production systems (APSs) are adapted tAuthorsDaniel B. Fagre, Gregory Pederson, Lindsey E. Bengtson, Tony Prato, Zeyuan Qui, Jimmie R. WilliamsA century of climate and ecosystem change in Western Montana: What do temperature trends portend?
The physical science linking human-induced increases in greenhouse gasses to the warming of the global climate system is well established, but the implications of this warming for ecosystem processes and services at regional scales is still poorly understood. Thus, the objectives of this work were to: (1) describe rates of change in temperature averages and extremes for western Montana, a region cAuthorsG.T. Pederson, L.J. Graumlich, D.B. Fagre, T. Kipfer, C.C. MuhlfeldMass balance of a cirque glacier in the U.S. Rocky Mountains
Glacier National Park, Montana, USA, contains 27 cirque glaciers, most less than 1 km2 and together comprising about 17 km2. These glaciers lie at relatively low elevation (2000 – 3000 m a.s.l.) and latitude (48o N) and have undergone dramatic retreat since the mid-nineteenth century, when an estimated 150 glaciers existed. Continuing volume losses and the disappearance of glaciers in recent decadAuthorsBlase A. Reardon, J. T. Harper, Daniel B. Fagre - Web Tools
