It is indisputable that #humans caused much of the #ClimateChange over the past few centuries. But still, I am curious about the effect, if any, of the Earth's gyroscopic #precession on the climate.

The Earth's Free Core Nutation (#FCN) motion is essentially a slight misalignment between the mantle's spin axis and the fluid core spin axis (I greatly exaggerated it here for ease of visualization). The camera starts in an inertial reference frame and slowly moves to the mantle's frame. As seen from the mantle the core seems to wobble!
This is all caused by the Earth's slow #precession. The fluid core lags a bit resulting in a small misalignment.

"If our #GalacticCentre has a #darkmatter #soliton core, some of the stars orbiting about the supermassive #blackhole (Sgr A*) would be crossing the soliton core boundary. In this article, we report the first theoretical study on how the dark matter soliton core near the Sgr A* could affect the surrounding stellar orbital #precession": https://arxiv.org/abs/2212.01979
