providing freedom and mental well-being, loss of sea ice can be argued to represent environmental dispossession of these communities . Traditional ways of life are therefore threatened, and resulting changes would be transformative rather than adaptive. Similarly, changes in streamflow affecting the availability of species for traditional hunting can also negatively impact Indigenous communities . Such changes are already being seen at current levels of warming, but studies remain somewhat limited in number, so this assessment is assigned medium confidence because of medium evidence and medium agreement. WGI conclude that it is virtually certain that further warming will lead to further reductions in Northern Hemisphere snow cover, and mass loss in individual glacier regions is projected to be between approximately 30% and 100% by 2100 under high-warming scenarios . Streamflows are projected to change in most major river basins worldwide by several tens of percent at 4℃ global warming .
