Arctic sea ice volume refreeze has come 7% of the way from Summer Minimum to full refreeze per October 21st. The lowest volume year ever, 2017, for comparison, was at 12%.
A: Here: Arctic Sea Ice Volume for September 2019 from PIOMAS
Q: How can anyone know if there is a full refreeze?
A: Easy. Use a computer. If you have e.g a 17 thousand km³ volume melt, and then the refreeze is also 17 thousand km³, then you have a full, or 100%, refreeze.
Q: Why would I even do that?
A: Let’s say you want to know how much ice refreezes compared to how much ice that melted away.
Due in large part to ongoing Collapse of Arctic Sea Ice our Frozen Earth is Going South.
