Changing Arctic ecosystems: ecology of loons in a changing Arctic [More info]
Changes in Arctic sea ice and permafrost will likely affect populations of wildlife. Migratory birds such as loons rely on freshwater lakes in the Arctic for nesting and food supply; we are studying how their populations are affected by these changes.
Changing Arctic ecosystems: sea ice decline, permafrost thaw, and benefits for geese [More info]
Loss of sea ice has increased ocean wave action, changing coastal habitats. For some geese this has been a positive change, increasing the amount of coastal area that supports vegetation the geese feed on.
PDF Climate Variability and Change [More info]
This fact sheet focuses on climate variability and change and how USGS research can strengthen the Nation with information needed to meet the challenges of the 21st century.
Climatic changes and effect on wild sheep habitat [More info]
Preliminary results indicate significant changes in Dall sheep diet accompanying vegetation changes and upslope retreat of glaciers.
DOI Climate Science Centers--Regional science to address management priorities [More info]
Locations of USGS science centers focused on climate change, with a brief description of the scientific focus and regional partner organizations.
PDF Detecting Evidence of Climate Change in the Forests of the Eastern United States [More info]
The relation between seasonal forest change and weather is being tracked and analyzed by comparing precise field observations to regional patterns shown in long-term satellite imagery.
PDF Integrated monitoring of ecological conditions in wetland-upland landscapes [More info]
Landscapes of interwoven wetlands and uplands offer a rich set of ecosystem goods and services. Changes in climate and land use can affect the value of those services. We study these areas to understand how they may be changing.
National Climate Change and Wildlife Science Center [More info]
Coordinates our efforts to address challenges resulting from climate change and to empower natural resource managers with rigorous scientific information and effective tools for decision-making.
Polar bear and walrus response to the rapid decline in Arctic sea ice [More info]
The Arctic is warming faster than other regions of the world due to positive climate feedbacks associated with loss of snow and ice. The USGS has modeled the future responses of polar bear and Pacific walrus populations to this environmental change.
PDF Remote sensing of land surface phenology [More info]
Shows how we can use remote sensing to study natural phenomena that vary seasonally but whose timing is affected by both shorter- and longer-term variations in climate or other, similar environmental conditions.
