I guess this would fit in science. :2razz:

Does it make sense that an open soda would go flat faster during times of higher humidity? If so, what would cause this?

I would say yes, but probably not noticeably.

When you open a soda, the carbon-dioxide (carbonation) starts getting released into the air due to the pressure differences between the bottle and ambient air. The more humid the air is, the lighter the air pressure becomes. This makes the differential pressure higher because ambient pressure is now lower, which would speed up your decarbonation.

Temps and pressures are the only things that really make a difference in the solubility of CO2 in water. I think you might be missing part of the information needed, so I'll make one assumption and go from there. IF it's warm out and the soda is cold, then a higher humidity will mean more water condensing from the air onto the soda container, which in turn warms the soda more and makes the CO2 less soluble. Under those conditions higher humidity would cause the soda to go flat faster.
