'''The projected frequency and magnitude of floods and droughts in some regions are smaller under 1.5°C than under 2°C of warming (''medium confidence'').''' Human exposure to increased flooding is projected to be substantially lower at 1.5°C compared to 2°C of global warming, although projected changes create regionally differentiated risks (''medium confidence''). The differences in the risks among regions are strongly influenced by local socio-economic conditions (''medium confidence''). {3.3.4, 3.3.5, 3.4.2}

'''Risks of water scarcity are projected to be greater at 2°C than at 1.5°C of global warming in some regions (''medium confidence'').''' Depending on future socio-economic conditions, limiting global warming to 1.5°C, compared to 2°C, may reduce the proportion of the world population exposed to a climate change-induced increase in water stress by up to 50%, although there is considerable variability between regions (''medium confidence''). Regions with particularly large benefits could include the Mediterranean and the Caribbean (''medium confidence''). Socio-economic drivers, however, are expected to have a greater influence on these risks than the changes in climate (''medium confidence''). {3.3.5, 3.4.2, Box 3.5}
