Projected change in access for maritime and land-based transportation in the Arctic by mid-century

Change in access is an inevitable consequence of cryospheric change in the Arctic, and is probably the most influential factor affecting Arctic society. Some areas will be more accessible, such as areas previously covered by sea ice, whereas ice roads will be less accessible. Human activities will be affected in a variety of ways: while some people and businesses will benefit from the changes, others will lose out.
