Milankovitch Cycles and Glaciation

The episodic nature of the Earth's glaciation periods within the present Ice Age (the last couple of million years) have been caused primarily by cyclical changes in the Earth's circumnavigation of the Sun.

Variations in the Earth's
eccentricity, axial tilt, and precession comprise the three dominant cycles, collectively known as the Milankovitch Cycles for Milutin Milankovitch, the Serbian astronomer and mathematician who is generally credited with calculating their magnitude. Taken in unison, variations in these three cycles creates alterations in the seasonality of solar radiation reaching the Earth's surface.

These times of increased or decreased solar radiation directly influence the Earth's climate system, thus
impacting the advance and retreat of Earth's glaciers.

It is of primary importance to explain that climate change, and subsequent periods of glaciation, resulting from the following three variables,
is not due to he total amount of solar energy reaching Earth.

The three
Milankovitch Cycles impact the seasonality and location of solar energy around the Earth, thus impacting contrasts between the seasons.

The combination of the long term
Milankovitch cycles and the 11 year Sun Spot cycles covers the TWO MAJOR factors involved in Global Climate Change. Any other factors that the climate hoaxers claim effect GLOBAL climate is a joke.
Eccentricity - 100,000 Year Cycles

Eccentricity is, simply, the shape of the Earth's orbit around the Sun. This constantly fluctuating, orbital shape ranges between more and less elliptical (0 to 5% ellipticity) on a cycle of about 100,000 years.

These oscillations, from more elliptic to less elliptic, are of prime importance to glaciation in that it alters the distance from the Earth to the Sun, thus changing the distance the Sun's short wave radiation must travel to reach Earth, subsequently reducing or increasing the amount of radiation received at the Earth's surface in different seasons.

Today a difference of only about 3 percent occurs between aphelion (farthest point) and perihelion (closest point).

This 3 percent difference in distance means that Earth experiences a 6 percent increase in received solar energy in January than in July. This 6 percent range of variability is not always the case, however.

When the Earth's orbit is most elliptical the amount of solar energy received at the perihelion would be in the range of 20 to 30 percent more than at aphelion.

At present the orbital eccentricity

is nearly at the minimum of its cycle.

These continually altering amounts of received solar energy around the globe result in prominent changes in the Earth's climate and glacial regimes.

Axial Tilt - 41,000 Year Cycles

Axial Tilt
, the second of the three Milankovitch Cycles, is the inclination of the Earth's Axis in relation to its plane of orbit around the Sun. Oscillations in the degree of Earth's axial tilt occur on a periodicity of 41,000 years from 21.5 to 24.5 degrees.

At present, axial tilt is in

the middle of its range.

Today the Earth's axial tilt is about 23.5 degrees, which largely accounts for our seasons. Because of the periodic variations of this angle the severity of the Earth's seasons changes.

With less axial tilt the Sun's solar radiation is more evenly distributed between winter and summer. However, less tilt also increases the difference in radiation receipts between the equatorial and polar regions.

One hypothesis for Earth's reaction to a smaller degree of axial tilt is that it would promote the growth of ice sheets.

This response would be due to a warmer winter, in which warmer air would be able to hold more moisture, and subsequently produce a greater amount of snowfall. In addition, summer temperatures would be cooler, resulting in less melting of the winter's accumulation.

Precession - 23,000 Year Cycles

Precession is the Earth's slow wobble as it spins on axis. This wobbling of the Earth on its axis can be likened to a top running down, and beginning to wobble back and forth on its axis.

The precession of Earth wobbles from pointing at Polaris (North Star) to pointing at the star Vega.

When this shift to the axis pointing at Vega occurs, Vega would then be considered the North Star. This top-like wobble, or precession,
has a periodicity of 23,000 years.

Due to this wobble a climatically significant alteration must take place. When the axis is tilted towards Vega the positions of the Northern Hemisphere winter and summer solstices will coincide with the aphelion and perihelion, respectively.

This means that the Northern Hemisphere will experience winter when the Earth is furthest from the Sun and summer when the Earth is closest to the Sun.

This coincidence will result in greater seasonal contrasts.

The third and final of the Milankovitch

Cycles is Earth's

At present, the Earth is at perihelion and

is very close to the winter solstice.


America's education’s professional schools in medicine, business, math, science, and engineering are the world’s best. However, a liberal-arts major no longer certifies that a graduate will be able to read, reason, compute, or draw on a body of knowledge better than those without a degree. "The decline of the university has been an ongoing tragedy since the 1960s, but the erosion has accelerated because of ideological bias and its twin, incompetence."
