Nenana Ice Classic - Official Date and Time the River moved now Available
The movement of the tripod on the Tanana River ice tripped the time clock on 2020-04-27 at 12:56:00
Timing everything from the vernal equinox given this plot:
So this years data shows a continual decrease, year on year, from about 1964 onwards (on average!).
No thermometer juggling possible, no tree rings to bodge, no models to distrust. Is this a real indicator of AGW?

2019 Nenana - River Ice breakup
The Nenana Ice Classic for 2019 ended when the Tanana river ice broke up on 14th April 2019 at 12:21 AM.
Two days before breakup:
Plots below assume AST throughout the record.
A large drop this year (earlier breakup) but is within the bounds of noise in this very noisy system. It does follow the downward trend from the 1970s.
