Just look at washingtonstate.edu and search precession. ...there is verifiable evidence for warming due to precessional axial tilt...and golly its
Precession of the equinoxes does not affect the axial tilt. All it does is change the time of year at which the equinoxes occur and where the
rotational axis "points." In a few thousand years the spring equinox will happen in summer and Polaris will no longer be the North Star. However, the
tilt of the Earth's axis will not have changed any appreciable amount.
There is a very long term change in the axial tilt, as well as changes in the Earth's orbit which are also very long term. These changes conspire to
produce what are known as the Milankovitch Cycles. Which does, indeed, have long term effects on climate. The interesting thing is, our current
position in the cycle indicates that temperatures should be falling (very, very slowly), not rapidly rising.
It should also be noted that the drift of the magnetic poles also has nothing to do with axial tilt.
