Since satellites first began monitoring the Arctic in 1979, the average area covered by sea ice has shrunk by at least 40%. The average thickness of the ice has fallen by more than half over the same time period. These rapid changes have left climate scientists facing an urgent question: when will Arctic sea ice disappear? The pace of change is most stark in September, the end of summertime in the Arctic. Each year, Arctic sea ice goes through a seasonal cycle, growing in area and thickness through the cooler winter months before shrinking back again as temperatures rise in the spring and summer. The point at the end of summer when sea ice reaches its lowest level for the year is known as the “sea ice summer minimum”. This year, the sea ice minimum is the second smallest on record, beaten only by the sea ice low seen in 2012.
