Three Decades of Changes in Permafrost Temperature along the Alaskan Permafrost/Ecological Transect

摘要

The presented materials show that the permafrost temperatures in Alaska observed during the last 30 years were generally increasing at almost all the sites. However, the rate and, sometimes, even the direction of these changes were not the same for different time intervals and for different locations. This conclusion makes it clear that only specific information on permafrost dynamics collected at specific locations and for specific time intervals can be used for interpretation of changes in other environmental characteristics that are strongly related to changes in permafrost. The usage of global or even regional trends in permafrost evolution for this purposes may be misleading.
