Does the proof of work needed to attach a transaction fluctuate, if so, what causes the increase/decrease?

Proof of work does not increase over time automatically. It may be that the IOTA foundation or the majority of nodes will decide later that more PoW (or less) is needed, so they can adjust the MWM ...
