Simulated changes in aridity from the last glacial maximum to 4xCO2

Greve, Peter; Roderick, Michael; Seneviratne, Sonia I

Description

Aridity is generally defined as the 'degree to which a climate lacks moisture to sustain life in terrestrial ecosystems'. Several recent studies using the 'aridity index' (the ratio of potential evaporation to precipitation), have concluded that aridity will increase with CO2 because of increasing temperature. However, the 'aridity index' is—counterintuitively—not a direct measure of aridity per se (when defined as above) and there is widespread evidence that contradicts the 'warmer is more...[Show more]
