TS.C.4.5 Flood risks and societal damages are projected to increase with every increment of global warming . The projected increase in precipitation intensity  will increase rain-generated local flooding . Direct flood damage is projected to increase by four to five times at 4℃ compared to 1.5°C . A higher sea level with storm surge further inland may create more severe coastal flooding . Projected intensifications of the hydrological cycle pose increasing risks, including potential doubling of flood risk and 1.2- to 1.8-fold increase in GDP loss due to flooding between 1.5℃ and 3ºC . Projected increase in heavy rainfall events at all levels of warming in many regions in Africa will cause increasing exposure to pluvial and riverine flooding , with expected human displacement increasing 200% for 1.6℃ and 600% for 2.6°C. A 1.5°C increase would result in an increase of 100-200% in the population affected by floods in Colombia, Brazil and Argentina, 300% in Ecuador and 400% in Peru . In Europe, above 3ºC global warming level, the costs of damage and people affected by precipitation and river flooding may double.
