So looking at the IERS LOD plot going all the way back it seems to
me that we have been missing the big signal for about five decades:

How did we not notice that earlier ?
In the last paragraph of the IERS Conventions, IERS Technical Note 36,
section 6.1 Conventional model based on the EGM2008 model, we find:
"There may be decadal variations that are not captured by the models."
Can anyone elaborate on what these 'decadal variations' may be?
