AbstractA snapshot of permafrost thermal state in northern Canada during the International Polar Year was developed with ground temperature measurements from about 170 boreholes. The measurements span a wide range of ecoclimate and geological conditions and are at various elevations. Ground temperatures within the discontinuous permafrost zone are generally above -2°C and range to as low as -15°C in the continuous zone. Permafrost temperatures have generally increased across northern Canada for the past several decades, with greater warming rates occurring north of tree line. Consequently the spatial diversity of permafrost thermal conditions is decreasing over time.
