The projected demise of Barnes Ice Cap: Evidence of an unusually warm 21st century Arctic

As a remnant of the Laurentide Ice Sheet, Barnes Ice Cap owes its existence and present form in part to the climate of the last glacial period. The ice cap has been sustained in the present interglacial climate by its own topography through the mass balance‐elevation feedback. A coupled mass balance and ice‐flow model, forced by Coupled Model Intercomparison Project Phase 5 climate model output, projects that the current ice cap will likely...
