Content: Not all years were "typical," of course. Sometimes the sea ice never completely moved out of the Barrow area all summer. In other years, October would come and the sea ice would be as far offshore as 250 miles. Changes in sea ice lead to local climate change
The long-term record of Barrow's climate traces this autumn mix of icy and mild Octobers. Over the past nine decades, some Octobers were warm and some cold, depending on whether sea ice was far from shore or near the coast. But as more and more ice has been lost in the summer in the seas beyond Barrow and not returned until late in the autumn, early autumn temperatures have risen dramatically. Average October temperatures in Barrow, Alaska, since 1920. Over the past nine decades, Barrow has experienced both warm and cold Octobers, with a string of warm Octobers in the last decade. Graph based on data provided by Rick Thoman. This rise in temperatures is directly related to the lack of sea ice near the shore.
