Today is a slightly interesting anniversary of sorts: yesterday's reading of 13,110,194 km2 marks the 100th consecutive day that JAXA extent has started with the number 13. That is, since the number climbed out of the 12s on January 15, it has stayed between 13,000,000 and 13,999,999 (with an average of 13,599,071, a median of 13,659,812, and a standard deviation of 228,485).
How's that for a plateau?
I haven't looked back to see how unusual it is for any of the ice metrics to stay in such a relatively narrow range for such an extended period, though I suspect such a thing probably falls into the "unusual but not rare" category.
