Has anyone considered that there may be a second axis the Earth rotates on explaining Ice Ages, and the melting of the Glaciers, we have only been observing Earth for a short period of time, considering it's age.

There is no such thing as the first axis either, moron

There is only one axis - axis is the term for an imaginary line around which an object spins. The Earth's axis is the line around which the Earth rotates. It is tilted to the ecliptic by 23.5 degrees at this time, and that is what gives us our seasons. A line drawn from the North axial pole to the south axial pole goes through the center of the Earth (they are antipodal).
The actual cause of Ice Ages has been debated. They could be caused by increased dust in the solar system, decreased solar energy output, a change in the axial tilt of the Earth, and a number of other causes.
And there is some evidence to suggest that massive volcanic eruptions eject so much dust and gases into the atmosphere that the global weather can be severely effected (what are sometimes called "Little Ice Ages").
A paper written by Benjamin Franklin in 1783 blamed the unusually cool summer of 1783 on volcanic dust coming from Iceland, where the eruption of Laki volcano had released enormous amounts of sulfur dioxide. Temperatures in the northern hemisphere dropped by about 1°C in the year following the Laki eruption.
Most recently, the 1991 explosion of Mount Pinatubo in the Philippines cooled global temperatures for about 2-3 years, interrupting the trend of global warming which had been evident since about 1970.

Possibly, but a more likely scenario is that the Earth was impacted by a large meteorite and this effected the Earth's rotation and rotation around the sun, pushing the earth farther away from the Sun, neatly explaining both the extinction of the dinosaurs and the Ice Age.

If there were such a thing, observations would have seen it by now; the instrumentation is exquisitely sensitive. But your idea is not totally off the wall; it is possible that perturbation of the earth's axis (mostly by Jupter's gravity) may have had something to do with ice ages.

The inertia of the earth is so great that while the direction of the axis is slowly precessing, as shown by ancient records about what is the North Star, etc., the chances of it revolving around a second axis are nil. There are plenty of other causes available.

have you ever considered that the magnetic poles on earth shift all the time the magnetic north is in the south and the magnetic south is in the north
