From: The long-term fate of permafrost peatlands under rapid climate warming
Five phase model for degrading permafrost peatlands in response to increasing temperature.
Each column corresponds to one of five distinct phases, identified in the top row. Symbols in the conceptual model represent the following hydrological fluxes: R = runoff; D = shallow drainage; P = precipitation; ET = evapotranspiration; I = infiltration. The bottom row illustrates ecohydrological stability of the system using a ball-and-cup analogy27. The first phase (‘intact’) represents the only stable basin of attraction before climate-driven change alters the system state.
