Dear sir:
I am interested in Astronomy for a Special Reason.
I hope that does not prevent you from considering my request.
I want to know more about an area of Solar System Astronomy.
In Particular, The Position of the Earth's Rotational axis, relative to a perpendicular plane, tangent to the radius of the elliptical orbit around the Sun, in a narrow arc located closest to the Sun, at one the foci.
The reason, for for my interest the disputed Cause of Global Warming.
I believe Global Warming is probably due to the Precessional Rotational cycle of Earth's Orbital Axis.
My Reasons are:
1st. Greenland was farmland about 800 AD Re: Eric the Red and Leif Ericson. This is roughly about HALF WAY through the 2600 years, 1300 years + 800= 2100 years, with some overlap, and my lack in knowledge of figures involved.
2nd. About 1948 or 1949, I read an article in a petroleum engineering Journal, which Stated the Probable Reason for Glacial Ice Sheets, across The North American Continent , was the Precessional Rotation of the Earth's Rotational Axis.
If the Precessional Axis of the earth's axis is close to or in a plane, perpendicular to the elliptical axis in an arc of Earth's Orbital path, closest to the Sun, a condition of Close to Equal Warming Pole to Pole, could result in a considerable amount of Redistribution of the Latent Heat Energy (Negative) in the Polar Regions, thus possibly altering our Climate, Drastically.
This doesn't Necessarily mean disaster for Earth's Inhabitants.
It might Possibly be Beneficial To Us.
We can know if The Precessional Rotation of Earth's Axis is a Probable for Reason for Global Warming by knowing the position of the rotational axis in its 2600 year cycle nearest the focus of Earth's Orbital path.
If it coincides with the present equal warming of Earth's Polar Regions we have reason to believe, Global Warming is dependent on this Precessional Cycle.
If the Precessional Orbital Rotational axis, Cycle is Close to 2600 years, approximately 80 years time is required for traversal of 1 ° of arc around the 360 degrees, of precessional Rotation.
PRECESSION
and other fluctuations in Earth's Orbit
Consequences of changes in Earths Position in space in its orbital path, due to Earth's rotational axis and its Precessional cycles.
One period of Orbital Precession of Earth's Orbital axis is 26,000 Years.
This One is caused by the Moon and the Sun's Gravitational Pull on Earth.
Another is a 71,000 year cycle caused by the Other Planets in the Solar System.
Due to the Planets, Earth's Orbital Axis Precesses about the Sun about every 71,000 years. Together these cause an oscillation in the Ellipticity of Earth's Orbit.
The 26,000 year Spin-axis Precession of Earth interacts with its 71,000 year Orbital precession, causing an additional 41,000 year Oscillation in the Tilt of Earth's Axis of about 1.3 degrees from its average value of 23.3 degrees.
The cycle length is not constant and depends on positions of the planets through time.
The Tilt maximum 24.2 degrees occurred approximately 95,000 years ago.
The Tilt decreased since then.
The rate rate of change of TIlt is now near Maximum.
The most obvious consequence of this Rate of Change of Tilt results in movement of Tropics of Cancer and Capricorn MOVING TOWARD THE EQUATOR.
The Movement of the Tropics toward the Equator is Greater then 14 meters per year.
This Actual Tropics in 1908 at the date of Publishing my Source at about 1 kilometer closer to Equator.
The Arctic Circles likewise have moved towards the Respective Poles as well.
Temperate Zones gain about 1550 Square Kilometers each Year.
