In Yukon, the zone of continuous permafrost might have moved poleward since 1899, but accurate records only go back 30 years. It is thought that permafrost thawing could exacerbate global warming by releasing methane and other hydrocarbons, which are powerful greenhouse gases. It also could encourage erosion because permafrost lends stability to barren Arctic slopes. Arctic temperatures are expected to increase at roughly twice the global rate. The Intergovernmental
