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.
-- "Ice Age" was not caused by Earth's precession.
-- According to one reasonable definition of what is meant by "Ice Age",
the most recent one has not ended yet. Follow the < Related Link > below

Precession, which in this case refers to a movement of Earth's axis. A full "turn" takes about 26,000 years.
It depends on what object you are talking about. If you are asking about the precession of the Earth's axis, then that is about 26,000 years.
Yes - more or less. It changes its direction in space ("precession") very slowly, making a full cycle every 26,000 years or so.Yes - more or less.

seasons are caused by the tilt of the earth. since the earth is in a slight eliptical orbit around the sun, when we are closer to the sun in January is where the northern hemisphere will still have winter and further from the sun in July when summer occurs. this is expected to flip in 26,000 years because of earths 3rd axis known as axial precession
'Precession' might be described as 'axial wobbling'. If we think of the Earth's North and South Poles, they lie on a line directly through the centre of the Earth. This line is angled at 23.5 degrees to the orbital plane. As a result it gives us the seasons. However, this line that is tilted at 23.5 degrees is NOT a static angle, but varies over thousands of years. Currently it is decreasing , and will eventually reach an angle of approximately 20 degrees (the seasons will be less extreme). Whereupon, it will then start to increase again to about 30 degrees (the seasons will become more extreme) . This tilting movement is called precession. As an experiment, if you have a child's spinning top or a gyro, set it spinning. You will notice that it 'wobbles', this is precession. The Earth does exactly the same, over thousands of years.

Due to the earths precession (How the earth 'wobbles' on its axis) the pole star changes over time. Though this takes many, many years

Precession
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.
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.

Neither it is 25,800 years
21,000-26,000 years, caused by wobble of earth about its axis.
