SR1.5  concluded with medium confidence that global warming of 2ºC would lead to an expansion of the area affected by flood hazards, compared to conditions at 1.5℃ global warming. Both AR5  and SROCC  concluded that spring snowmelt floods would be earlier , and hazards from floods involving meltwater will gradually diminish, particularly at low elevation . SROCC  and AR6 WGI Chapter 9 stated that given limited evidence and the complexity of the process, the changes of glacier-related floods under climate change are not clear. AR6 WGI Chapters 8 and 11 summarised that there is medium confidence for a general increase in flooding due to warming, but there are significant regional and seasonal variations.
