  • Permafrost in Central Asian is present in the Qinghai-Tibet Plateau in China, the Tien Shan Mountain regions in China, Kazakhstan and Kyrgyzstan, the Pamirs in Tajikistan, and in Mongolia. Monitoring of the ground thermal regime in these regions
  • over the past several decades has shown that the permafrost has been undergoing significant changes caused by climate warming and increasing human activities. Results and discussion of the measured mean annual ground temperature (MAGT) at a depth of 6 m
  • A snapshot of the thermal state of permafrost in northern North America during the International Polar Year (IPY) was developed using ground temperature data collected from 350 boreholes at various elevations within the Cordillera. In concert
  • of ground warming have been variable, but are generally greater north of the treeline. Latent heat effects in the southern discontinuous zone dominate the permafrost thermal regime close to 0°C and allow permafrost to persist under a warming climate
  • . 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
  • ground temperatures measured in existing and new boreholes show a substantial warming during the last 20 to 30 years. Thawing of permafrost is most noticeable within the discontinuous permafrost domain. However, permafrost in Russia is also starting
