Could the Earth's Precessional motion {40,000 years for one loop} cause or contribute to Global warming?
Would you care to postulate a hypothesis as to how it might?plutoisacomet said:Could the Earth's Precessional motion {40,000 years for one loop} cause or contribute to Global warming?
The Earth's Precessional motion is the gradual change in the orientation of the Earth's rotational axis over a period of approximately 26,000 years. This is caused by the combined effects of the Earth's axial tilt and its orbit around the sun.
The Earth's Precessional motion is primarily caused by the gravitational pull of the moon and sun on the Earth's equatorial bulge. This pull causes a slight wobble in the Earth's rotation, resulting in a change in the orientation of its axis.
The Earth's Precessional motion does not directly affect the seasons. However, it does cause a gradual change in the position of the Earth's rotational axis relative to its orbit around the sun, which can have a minor impact on the length and intensity of the seasons over a long period of time.
The Earth's Precessional motion takes approximately 26,000 years to complete one cycle, known as a Great Year or Platonic Year. This is the time it takes for the Earth's axis to make a full circle and return to its original position.
The Earth's Precessional motion can have a minor impact on Earth's climate over a long period of time. It can cause a change in the distribution of sunlight and can also affect the Earth's orbital eccentricity, which can influence the amount of solar radiation reaching different parts of the Earth, potentially leading to changes in climate patterns.
