Arctic sea ice extent refreeze has come 79% of the way from Summer Minimum to full refreeze per December 25th. The lowest extent year ever, 2016, for comparison, was at 75%.

Q: Where’s the data source for this plot?
A: Here:
Q: How can anyone know if there is a full refreeze?
A: Easy. Use a computer. If you have e.g a 10 million km² extent melt, and then the refreeze is also 10 million km², 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.
