The earth’s axis, as most scientist and astronomers say, is tilted 23.5 degrees from its orbital plane. The earth is rotating counter clockwise when viewing from the northern star, Polaris. According to scientists and historians, the earth’s axis is shifting. This process of shifting is called “precession”.
This occurs every 26,000 years. One effect of precession of the earth’s axis is the change of the northern star. As of this date, the northern star that is identified is the Polaris. Axial precession will shift the northern axis to other stars near the Polaris. Second, the equinox climate can also change with respective to the dates of its first day in the year. Third, this process can bring about the change of shape of the earth’s orbit. These effects have great impact on the earth’s over-all climate.
Axial precession is caused by the gravitational pull of the sun and the moon and other heavenly bodies in the earth’s surface. The change of the angle of tilt was apparent due to Hipparchus and Ptolemy observations. Also, there are also several tribes around the world such as the Mayans, Egyptians and many others have nurtured this belief. However, there are no solid proofs that axial precession can bring about an extreme change in the earth’s climate causing havoc results to man and properties.
