In Alaska, Western Canada, and Eastern Russia average winter temperatures have increased as much as 4 to 7°F (3-4°C) in the past 50 years and are projected to rise 7-13°F (4-7°C) over the next 100 years.
Arctic sea ice during the summer is projected to decline by at least 50 percent by the end of this century with some models showing near-complete disappearance of summer sea ice. This is likely to have devastating consequences for some arctic animal species such as ice-living seals and for local people for whom these animals are a primary food source. At the same time, reduced sea ice extent is likely to increase marine access to some of the region's resource
