Abstract

This paper raises a problem and invites for discussion. The problem aims at illustrating the deficit in the water budget and its energy side consequences. Water extremities due to climate change and other anthropogenic forcings can be investigated in the context of a coupled atmosphere-water cycle-energy exchange model, which may explain the water cycle drivers of excess warming attributed to climate change. The approach adds a third element to the blue and green water fluxes (surface water and water used by vegetation): red water, i.e. the water equivalent of the heat released at the surface in the absence of water for evapotranspiration. The question is whether and, if so, what policy should be put in place to reduce this deficit?
