based upon the earth being a gyro precessing around the sun

I wouldn't normally answer a question I don't know the answer to but I feel I must correct some that are really, REALLY wrong [Billy B]
The axis if the earth does indeed change. I think it takes 26000 years for the axis to go round it's precession in the same way a spinning top does. The axis of the earth is inclined 23.5 degrees to the ecliptic [the disk of the route we take around the sun]. This causes the seasons but the axis shifts which means the seasons do too.
It is likely that ice ages are contributed to by this process. However the ice age process takes tens of thousands of years and we have scientific data for the last 100 years.
The truth of the matter is we don't know squat....

The axis has no reason to change,so that won't be a factor.
Precession will not influence the weather it's always been there.
Global climate change will be caused by changing the environment with green house gasses.
The sun will eventually be a factor but that could be hundreds of millions of years from now.

If the Earths axis of rotation where to change you would have bigger things to worry about like that huge proto planet about to smash into the Earth. In order for the axis to change some thing would have to impart some major angular momentum to the Earth like a huge proto planet, and if this occurred there wouldn't be anyone left to worry about it.
That said the axis of rotation of the Earth is responsible for the seasons in the higher latitudes, but if the axis shifted the Earth as a whole wouldn't be any warmed or colder since the Earth would still receive the same amount of energy from the sun. Some local climates would change but the global climate would still be the same overall.

The axis of the earth's spinning is indeed tilted with relation to the sun, and that affects us every year, that tilt is what causes summer and winter. If it was vertical, there'd be no seasons.
But it does not really contribute to 'global' warming, because as parts of the globe tilt away from the sun, causing shorter days and thus winter, the opposite is true for an equal portion of the other hemisphere.

I would say that the earth's gyroscopic orbit has no effect on climate change, it is almost entirely human activity. The Ice age was the best natural contribution to natural climate change. So we will either fry or have to wait for another ice age where we will all freeze. But I think another volcanic winter will sort out the mess the earth has got itself into.

At present it appears that earth has been observed by scientist to have an increse of 0.7 degree rise in themperature.If this is true then its due to the precession of the earth's poles.
Scientists have estimated a 22000 year cycle,for the poles to complete a full rotation.
