2012 record low (September 2012)
Arctic sea ice fell to its smallest September extent in the satellite record, far below anything previously observed. The 2007 record, set just five years earlier, was broken by a wide margin.
The 2012 minimum became the benchmark for extreme melt years, and no year since has matched it.
The record showed what a combination of long-term warming and favorable weather can produce, and it remains the lowest September extent on record.
The 2012 record is the reference point for the current story. The 2026 minimum is 10th lowest, but the record from 2012 still stands, showing the difference between an extreme weather year and the long-term trend.
