Why does warm coke have more fizz?

The other day i noticed that a bottle of coke that was left out, and thus warm, had a lot more fizz than one straight from the fridge. Why?

I believe I'm right in saying that the warmer something is, the more energy it has. It could be that the gas molecules are more energetic when the drink is warmer.

I wouldn't really know, though, as the butler always chills mine to 38oF before serving.  [^]

The solubility of gases decreases as temperature increases. So, at higher temperatures, more CO2 will 'come out' of the Coke. The reason must be along the lines of DrB. If the average kinetic energy is higher (i.e. at higher temperature) the CO2 molecules are more likely to break out of solution. Hence - more fizz.
A chemist could give us more idea about what goes on when a gas like CO2 dissolves in water,  perhaps.???
