A new approach to mapping permafrost and change incorporating uncertainties in ground conditions and climate projections
Spatially detailed information on permafrost distribution and change with climate is important for land use planning, infrastructure development, and environmental assessments. However, the required soil and surficial geology maps in the North are coarse, and projected climate scenarios vary widely....
