Global Change
Global Change research at the U.S. Geological Survey aims to reveal the consequences of global change, including climate change and variability, on ecosystem processes, structure, and function.
Climate change and its effects on natural resources and human communities are among the most challenging issues confronting our Nation. Understanding and communicating the nature of climate change impacts can be equally challenging because of the complexity of the processes that influence global and regional environmental change. Rates of change in temperature, sea-level rise, growing season length, sea ice extent, permafrost decline, the habitat of multiple species and many other climate-related variables are expected to accelerate through 2100.
Global change research in biology focuses on the response of ecosystems and biological communities and species to climate change and assesses future global climate change impacts. Projects support our partnership with the U.S. Global Change Research Program (USGCRP).
