It's been warm, with temperatures about 3C or 4C above normal for June, July and August, particularly to the north of Siberia where the temperatures have reached between 4C and 5C above average. Unusually clear skies over the Arctic this summer have caused temperatures to rise. More sunlight has exacerbated the loss of sea ice, which fell to a record low of 4.28 million square kilometers. People who live in the region are noticing changes in sea ice. The earlier break-up and later freeze-up affect when and where people can go hunting, as well as safety for travel.
