Presumably it is due to the fact that each day, any karma that was earned 30 days prior will roll out of your 30 day karma calculation, but not out of your total karma calculation. On any particular day, if you do not earn any karma, your total karma will remain unchanged, but if you did earn karma 30 days prior to the current day, your 30-day karma will change.
What that likely means is that just over 30 days ago you got two upvotes. That no longer goes into the 30 day but still counts towards your total. I would however recommend strongly on focusing more on the message that your karma sends overall in terms of what comments have been received well and which have not rather than look at minor fluctuations.

Yeah, my 30 day karma went down, got −2 but my total karma was unchanged. Weird. Had −42 now it’s −44 and my total didn’t change at all.

Maybe the values are cached, and recalculated at different moments.
