IH3444 - you're statement:
"Earth orbital fluxuates from very circular to elliptical, the shift to elliptical moves the earth approximately 3 million miles futher from the sun on the outer curves of the elliptical orbit. This leads to the ice ages. Hmmm, no tax revenue possibility on the earth orbital changes."
Some facts:
"The earth's orbit around the sun is not a circle. The earth's orbit around the sun is slightly elliptical. Therefore, the distance between the earth and the sun varies throughout the year.
At its nearest point on the ellipse that is the earth's orbit around the sun, the earth is 91,445,000 miles (147,166,462 km) from the sun. This point in the earth's orbit is known as perihelion and it occurs on January 3.
The earth is farthest away from the sun on July 4 when it is 94,555,000 miles (152,171,522 km) from the sun. This point in the earth's orbit is called aphelion."
This 3,000,000 mile difference is about a 3% difference and puts the northern hemisphere closer during our winter. Happens every year - nothing to do with ice age IMHO.
Looks like the variations that matter work on from 26,000 to 100,000 year cycles.
global warming (Earth science) :: Variations in Earth's orbit -- Britannica Online Encyclopedia
"The slight ellipse in the earth's orbit does have a slight impact on the amount of solar energy being received by the earth. This 3.3% difference in distance does not impact the earth as much as the seasonal variations, however.
On timescales of tens of millennia, the dominant radiative forcing of Earth痴 climate is associated with slow variations in the geometry of Earth痴 orbit about the Sun. These variations include the precession of the equinoxes (that is, changes in the timing of summer and winter), occurring on a roughly 26,000-year timescale; changes in the tilt angle of Earth痴 rotational axis relative to the plane of Earth痴 orbit around the Sun, occurring on a roughly 41,000-year timescale; and changes in the eccentricity (the departure from a perfect circle) of Earth痴 orbit around the Sun, occurring on a roughly 100,000-year timescale."
Is there some over enthusiastic denying going on. Is this a reason to invalidate everything posted. (comparison to throwing out the 3000 page multi year research.)
