Concrete as CO2 absorber? It is agreed that making Porland cement releases CO2, for heating but also due to the chemical reaction. Now I am informed that the concrete in my building is being damaged due to a slow but steady attack by CO2. So will the concrete ruins of our time be a CO2 absorber for the next generation?

CO2 is stored deep within the depths of the oceans, are they fizzy down there? The ocean's are great stores of CO2, especially at the high pressure seen at depths of over 1000m, or so I am informed. So are they fizzy down there, whats it like for a fish, do they basically live in a soda stream?
