Is there a name for the opposite reaction to the dissolution?

When atmospheric $\ce{CO2}$ reacts with water to form $\ce{H2CO3}$, this is called dissolution, isn't it? What term would you use for the opposite reaction when it occurs at atmospheric pressure (e.g. due to temperature change)? For a solid it would be precipitation, but here it is for a gas. 




[Effervescence](http://en.wikipedia.org/wiki/Effervescence) if there are bubbles and 


[Degasification](http://en.wikipedia.org/wiki/Degasification) more generally speaking.


There is also the term [outgassing](http://en.wikipedia.org/wiki/Outgassing), but that term is broader than just gas coming out of liquid solution.
