Ice cube melting point

Regelation: why does ice melt under pressure? - arXiv

pressure on its lower surface to lower the melting point of the ice at its base, melting the ice and allowing the glacier to slide over the liquid. Under the right conditions, liquid water can flow from the base of a glacier to lower altitudes when the temperature of the air is above the freezing point of water [1, 2] (left panel of Figure 3).
