I was about to make some joke about how this explained climate changed and meant we, in the end, need not worry about greenhouse gases.
But then I tried to look up what the actual impact of our planet’s tilt slightly shifting could be.
While I could not come up with anything meaningful, it appears glaciers melting also contributes to this [1].

From the press release linked in a comment above:
>The rotational pole normally changes by several meters within about a year, so changes due to groundwater pumping don’t run the risk of shifting seasons. But on geologic time scales, polar drift can have an impact on climate, Adhikari said.
Any siginificant movement of mass, particularly mass far from the axis of rotation, changes the dynamic balance and induces pole shift.
