Description :
This paper synthesizes the regional results and thereby characterizes the thermal state of permafrost for the polar regions of the Northern Hemisphere at the end of the Fourth International Polar Year (IPY) : North America, Nordic region and Russia. A comparison is also made between the current state and previous ground thermal conditions in order to characterize longer-term changes. Improved knowledge about the permafrost thermal state is important for multidisciplinary polar research. Increased permafrost knowledge is also particularly important for the design and maintenance of infrastructure in permafrost environments and for designing effective adaptation strategies for the local communities under warmer climatic conditions.
