If a magnetic field is affected by temp, then if the ice caps melt could east and west become magnetic north and south?

The radioactive decay in the earths in regions create alot of heat which makes the molten outer core convect around the solid inner core This creates the earths magnetic field and id think that process which happen over 3500km down will not be affected by the process of warming on a crust a few km thick.
The earths field could be starting to flip as at some points in the south there are regions with an anomolious field polarities.

No, the melting of ice caps will not result in a temperature big enough to affect the magnetic fields of the earth, as far as I know.

It has nothing to do with surface temperature at all. The temperature that drives it is the very high ones in the Earth's core. That allows a solid core, liquid lava and then the crust.
The poles have flipped many times in the past and will flip many times in the future. Indeed many scientist believe that the process has already started with the flow reversed at the mid Atlantic anomaly and other spots!

The magnetic field is generated by electric currents flowing deep inside the earth's molten core. There is no measurable effect of what is happening on the surface on the core.
The field will eventually collapse and reverse, but that process is likely not influenced by anything going on on the outside.
