In actuality the precession of the equinox is causing glaciers to retreat at one side of a polar ice cap, and at the same time grow on the other side.

The Earth rotates every 24 hours, so the Sunlight falling on one side of the polar icecap is basically the same as what fell on the other side 12 hours ago (and will fall again on the other side in another 12 hours).

This rotisserie effect means that glaciers on both sides of a polar icecap will be experiencing the same solar heating effect, and will have the same impact on their glaciers.

Precession of the Earth's axis occurs on a timescale of thousands of years, while human production of CO₂ and CH₄ has changed dramatically on a timescale smaller than 100 years.

Precession of the Earth's axis occurs on a timescale of thousands of years, while human production of CO2 and CH4 has changed dramatically on a timescale smaller than 100 years.

What you mentioned as above is truth. The winter month of a hemisphere, would take a much longer period to gradually become a summer month over a ~13,000 year period .

Nevertheless, a slight shift of the polar caps caused by the axial precession effect over a relatively short period of time, say in 100 years, would be sufficient to cause the glaciers at one side of the meandering ice cap to significantly retreat, while concurrently advance on another side.

I believe at this juncture, the UVS topic on "The paradoxical effect of nature" is called for.

The section that elaborates on the inductive resolutions of the UVS research, would be worth a thorough second reading.

From the UVS perspective, the photosphere on both hemispheres of the Sun subjected to its rotation, becomes a forced vortex pair.

The driving force for the solar polar vortex pair could come from the Sun revolving around the Galactic Center in a spiral arm of the galactic vortex, and this effect transforms the forced vortex pair into a stable and long-lived free vortex pair in the photosphere at the two polar regions that cyclonically spins around the polar axis.

The extremely large and stable polar vortex pair of the Sun, renders the polar caps phenomenon as long-lived corona holes, where coronal temperature and atmospheric density are suddenly dropped in the low pressure systems of the vortical voids of their vortex columns.

The vortically manifested vortex column on a surface of the Sun is a depressed void area, whereby the usual presence of plasmatic viscous matter required for the thermal convection is vortically displaced.

The vortical column effect thus also renders the sunspot's inert dark center phenomenon; the vortical void limits convection and therefore the umbra region is much cooler and less illuminated than the surrounding.

A sunspot is merely a harmonica manifestation of its solar polar vortex in its jet stream.

When the polar vortex pair of the Sun is intensified internally in the Solar System by the barycentric motions of the gas giants, its solar jet streams are thus intensified to manifest increased number of sunspot in clusters, this renders the sunspot cluster phenomenon.

This mechanism is similar to how the atmospheric polar vortex pair of Jupiter, impels its jet streams that in turn manifest and impel its satellite vortices.

See the UVS topic on "Vortices of Jupiter" for its comparative analysis.
