AR5 noted that global glacier mass loss is very likely to increase further during the 21st century . According to the SROCC , it is very likely that glaciers will continue to lose mass throughout the 21st century: from 18%  for RCP2.6 to 36% for RCP8.5. AR5  and SROCC  reported with high confidence that permafrost would continue to thaw in the 21st century, but the projections are uncertain. Constraining warming to 1.5℃ would prevent the thawing of a permafrost area of 1.5 to 2.5 million km2 compared to thawing under 2ºC  . AR5  and SROCC  concluded that Northern Hemisphere snow extent and mass would likely reduce by the end of the 21st century, both in plain and mountain regions. AR6 assessed with medium confidence that under RCP2.6 and RCP8.5 from 2015 to 2100, glaciers are expected to lose 18% and 36% of their early 21st-century mass, respectively .
