 +Polythermal conditions are ubiquitous among glaciers and ice sheets. ​ Fortunately,​ temperature and liquid water fraction are functions of a single enthalpy variable: a small enthalpy change in cold ice is a change in temperature,​ while a small enthalpy change in temperate ice is a change in liquid water fraction. ​ The unified enthalpy formulation described in this paper models the mass and energy balance for the three-dimensional ice fluid, for the surface runoff layer and for the subglacial hydrology layer, together in a single energy-conserving theoretical framework. ​ It is implemented in PISM.  Results for the Greenland ice sheet are compared with those from a cold-ice scheme.
