Global glacier mass loss since 2015 and 2100 was projected to be 18 + 13% by 2100 with 0.9 - 2.3℃ global warming and 36 + 20% with 3.2 - 5.4℃ global warming , which corresponds with previous findings . The regional glacier loss rate projections are unevenly distributed worldwide and considerably vary between scenarios . In most regions, 'peak water' has already been reached or is expected to be reached before mid- century  . The influence of the expected subsequent decrease in glacier runoff by the end of the 21st century will be more pronounced during droughts and dry seasons .
