Bubbling in the airlock and fermentation are not the same.....an airlock bubbles for various reasons, change in atmospheric pressure, change in temp, the cat brushing against the fermenter, it doesn't mean anything whatsoever, just like airlocks not bubbling mean nothing. It's a vent, a valve to release excess co2. Change in temp means that more than likely the gas in the headspace has expanded, like gasses to often do when heated, or the change in temp is causing some of the co2 to come out of solution. That's why it's not a good idea to equate a bubbling airlock with fermentation, because they can bubble independently of fermentation, or not bubble DESPITE fermentation
