By what process do air bubbles form in water?

I left a glass of water sit on the mini-fridge overnight, and in the morning there were little bubbles clinging to the walls of the glass. More than just a few. Googling led to this
page, where someone asks the exact same question. Apparently there are gases mixed in with the water, and the temperature affects their solubility (whatever that means.) Further googling led to this
page, which, in section M5, seems to discuss the matter. But it's written at a level I don't understand. Why doesn't the gas just rise to the surface? What is this whole solubility thing? Temperature affects it? What happens between the time when there are no bubbles, and the time when there are bubbles?
