Fizz occurs in carbonated drinks because carbon dioxide (a gas) is physically trapped between the water molecules that make up the majority of the drink (i.e. They are dissolved). Molecules are always bouncing around, and whenever one bounces towards the top of the drink and escapes into the air, we see a bubble. Temperature itself is a measure of how fast molecules are moving, so subjecting a fizzy drink to a higher temperature causes the molecules to bump around and leave the drink at a faster rate
