End of September assessment reinforces the “pause” in Arctic ice trends at this time of year since 2007, and arguably 2005.

NSIDC have now published the Arctic sea ice extents for the end of September. This is how things compare with previous years:

Although the minimum this year dipped below the last two years, the end of September assessment reinforces the “pause” in Arctic ice trends at this time of year since 2007, and arguably 2005.

Most interesting of all though is the phenomenal growth in extent during the month:

Recovery of ice since the end of August is the greatest since 2002, and is clear evidence of the cold conditions in the Arctic, probably coupled with the fact that the extent at the end of August was lower than it would have been otherwise because of storm activity.

We should also look at ice thickness, which has continued the strong recovery seen earlier in the year. Note that this year and last are much higher than the four preceding years of 2010-2013.
