I left 1/2 of a 24oz beer open in the fridge last light. This morning I re-discovered it, and tasted it ( after lunch) -- it wasn't totally flat as I expected. Did the lower temp help keep some CO2 in solution even though the container was open?

Yes, but it would have lost the rest fairly soon
Yup. There was actually a report in, I want to say Scientic American(?), that the real key to keeping things carbonated was just keeping them cold(er) - it was actually discussing champagne, but I don't see why it wouldn't apply to beer.

The CO2 WILL NOT dissolve or stay dissolved in the solution unless it is under pressure. Cold temps help slow down the CO2 loss, but it doesn't stop it. You lost some from last night, but the cold temps slowed down the loss.
