Evidence and Implications of Recent Climate Change in Northern Alaska and Other Arctic Regions The Arctic climate is changing. Permafrost is warming, hydrological processes are changing and biological and social systems are also evolving in response to these changing conditions. Knowing how the structure and function of arctic terrestrial ecosystems are responding to recent and persistent climate change is paramount to understanding the future state of the Earth system and how humans will need to adapt. Our holistic review presents a broad array of evidence that illustrates convincingly; the Arctic is undergoing a system-wide response to an altered climatic state. New extreme and seasonal surface climatic conditions are being experienced, a range of biophysical states and processes influenced by the threshold...

Spatial and temporal variability in the growth and climate response of treeline trees in Alaska Lloyd and Fastie investigated the response of trees growing at the cold margins of the boreal forest to climate variation in the 20th century. Working at 8 sites at and near alpine and arctic treeline in three regions in Alaska, they compared tree growth to historical climate data to document how growth has responded to climate variation in the 20th century.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
