people per year per country projected to be affected . Kinoshita et al.  showed that climate change contributes a 2.8-28.8% increase in global fatality for the period 2071-2100 compared to 1991-2005, but socioeconomic change  and associated vulnerability change  have a greater impact of the projected flood-related fatality rate than climate change alone. Winsemius et al.  discussed that projected flood damage could be reduced to 1/20th in absolute value with adequate adaptation strategies. Direct flood damages are projected to increase by 4-5 times at 4℃ compared to 1.5℃, highly depending on scenarios and assumptions .
