Within recent decades, and especially in the 21st century, we constantly see reports that total ice extent is the lowest, 2nd lowest or 3rd lowest ever recorded.  So far the lowest ever ice extent was in 2007 and we have charts and reports which show no such low extent since at least the 16th century.  It needs no great mathematical skill to deduce that if every year shows an ice extent amongst the lowest ever, there must have been some great change in the Arctic dynamic.
