In the last couple of million years, the Earth has experienced dozens of ice ages.
The last one ended about 15,000 years ago. We don't know if they are related at all
to the Earth's "precession", which is a 26,000-year-long "wobble" in the Earth's spin.
There is no reason for precession to have any effect on Earth's climate, since the
'tilt' of the axis remains constant throughout the cycle of precession.
Precession, which in this case refers to a movement of Earth's axis. A full "turn" takes about 26,000 years.
A complete precession cycle, such as Earth's axial precession, takes around 26,000 years to complete. This gradual shift in the orientation of Earth's axis affects the position of the equinoxes and solstices over this timescale.

The moon's gravity does have some influence on Earth's rotation and precession, but these effects are relatively minor compared to other factors such as the Sun's gravitational pull and internal processes within Earth. Precession is primarily caused by the gravitational forces of the Sun and Moon acting on the Earth's equatorial bulge. While long-term changes in Earth's rotation and precession can occur, they are gradual processes that unfold over thousands to millions of years.
Precession is the slow wobble of the Earth due to the fact that the Earth is not perfectly round and therefore the Sun and the Moon's gravitational pull is somewhat stronger on the equator of the Earth than elsewhere. A "torque" like this will cause any rotating object to wobble. The period of one complete precesssion cycle is almost 26,000 years. A consequences of the precession cycle is that the position on the Earth's orbit around the Sun where winter (in the North) is now will be where summer occurs in 13,000 years. This slow drift of the seasons prompted the Catholic church to call for the implementation of a new calendar called the Gregorian calendar which accounts for precession.
Earth's precession is believed to be one of the contributing factors to the ice ages, but it is not the sole cause. The most recent ice age, known as the Quaternary glaciation, began around 2.6 million years ago and ended approximately 11,700 years ago. This glacial-interglacial cycle was influenced by a combination of factors, including variations in Earth's orbit, tilt, and precession, as well as changes in atmospheric composition.

Precession
The next precession of the Earth's axis is already in progress and it occurs over a period of about 26,000 years. The exact timing of when one precession cycle ends and another begins is not easily pinpointed.
The Seven Years' War ended in 1763. It resulted in several treaties being signed including the Treaty of Paris, the Treaty of Saint Petersburg, and the Treaty of Hamburg.
No; in 13,000 years, the precession of Earth will have changed the axis half a cycle (the full cycle is about 26,000 years), so that the position of the axis will be the opposite of what it is now.No; in 13,000 years, the precession of Earth will have changed the axis half a cycle (the full cycle is about 26,000 years), so that the position of the axis will be the opposite of what it is now.No; in 13,000 years, the precession of Earth will have changed the axis half a cycle (the full cycle is about 26,000 years), so that the position of the axis will be the opposite of what it is now.No; in 13,000 years, the precession of Earth will have changed the axis half a cycle (the full cycle is about 26,000 years), so that the position of the axis will be the opposite of what it is now.
