The following excellent graph shows the decadal disappearance of Arctic sea ice volume clearly:

Note: Yearly ice gains & losses during even large parts of a particular year may be higher or lower than previous or succeeding years. However, data grouped into decades, clearly show no crossing or touching of decadal Arctic sea ice loss data lines.
Slip, sliding away!!!
