Content: In any year, there was a 25 percent chance the ice pack would be right off shore (red line) and a 75 percent chance it would be no more than 100 miles or so (orange line). The 100 percent probability line means the ice was always south of there; the 0 percent line means the ice was always north of there. Source: NOAA Technical Memorandum AR-34 (1982). 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.
