Why does the pH of circulating water rise naturally?

(Just a gentle question) Why does the pH of circulating water rise naturally? I’ve just started working with circulating water treatment and am a bit confused. Could someone please explain it to me? Thanks first!
I work on physical technologies for removing calcium and magnesium ions; we can talk about it
Circulating water is generally fresh water, which usually contains carbonates. In a circulating water tower, an air-blowing process is used to cool the circulating water by evaporating a certain amount of water. During this process, these carbonates decompose and are removed as carbon dioxide; acidic gases are released, and as a result, the pH level of the water rises (I guess there’s no need to explain the ionization process)
1. The axial flow fans on the cooling towers in chemical plants have relatively large air handling capacities. A cooling tower can be considered a vacuum cleaner.
1. External factor: The axial flow fans in the cooling tower have a high air volume; those in the chemical plant function like vacuum cleaners
