TS.C.4.4 Drought risks and related societal damage are projected to increase with every degree of warming . Under RCP6.0 and SSP2, the population that is projected to be exposed to extreme to exceptional low total water storage will reach up to 7% over the 21st century . Under RCP8.5, aridity zones could expand by one-quarter of the 1990 area by 2100. In southern Europe, more than a third of the population will be exposed to water scarcity at 2ºC, and the risk doubles at 3ºC, with significant economic losses . Over large
