Pole drift.

Perhaps https://en.wikipedia.org/wiki/Cataclysmic_pole_shift_hypothe...
Each ellipsoid is rigidly defined (well, some historic ones are sloppy), so WGS84 won't drift .. (that's a bold statement, is it true down to the micron and if so what are the absolute* datums to reference against?).
That said, there are literally hundreds of historic pre WGS84 ellipsoid|datum pairings, each with a somewhat different "survey map pole".
Historically geodectic poles have shifted as a function of datums.
The main point here, such as it is, was to poke at the infomation free aspect of "polar drift" as a comment .. which pole and what does that have to do with climate change? etc.
We still use many of those old ellipsis and datum’s today. When you’re doing human things, like surveying land, and defining property boundaries. It’s nice to work with a coordinate system which remains fixed relative to the area you’re surveying, and doesn’t drift due to annoying things like tectonic movement, or your entire country slowly tipping into the ocean.
Does it really matter if my house burns because of pole drift or because of climate change? I don't like it burning either way. So if there is something I can do against my house burning, (and I know there are things I can do against that) I will definitely try that. And I believe we agree that we could do things, right?
