Raw data September 8, 2013 10:58 am ER

/IceCapShrinkage.pdf

This is the only full list of Arctic summer ice coverage during the satellite era I could locate. The list is dated, so the last two years (2012 and 2013) were filled in using Japanese space agency data.

Figures may vary slightly from different sources due to different averaging and smoothing algorithms, and due to differences in how the terms “sea ice extent” or the related parameter, “sea ice area” are defined.

Again, its the trends over time that matter, not the individual values.

In millions of square km. Dates marked with asterisks are record-breaking lows.
