Permafrost degradation risk zone assessment using simulation models.

The article presents a study on the assessment of permafrost degradation through simulation methods in Greenland. It mentions the mathematical model of the current and future condition of the island's frozen ground which is driven by climate projections up to the year 2080. It also notes the development of the Permafrost Thaw Potential (PTP) concept which is the potential active layer increase as a result of climate warming and surface alterations.
