UPDATE: The post was premature. It may be day 59.
Antarctic minimum is approaching (or may have occurred) 2017 and 2018 were lowest minimums. 2019 is 10th lowest (although that may change a bit).
That kind of oscillation is “normal” and getting larger. The oscillation graph is just Day 49 but thats close to the normal day of min.

If one considers the linear trend from 1979-2016, it’s steadily rising, with not that much oscillating variance evident. Only post-2016 is a swing between highs and lows potentially “getting larger”. Even if it is, the oscillation to the downside is not getting any steeper — only to the upside.
