How is excessive content of `CO_(2)` responsible for global warming?

Explanation

We know that `CO_(2)` is very much essential for plants to carry photosynthesis. The gas is produced during various type s of combustion reactions and is relased into the atmosphere. It is taken up by plants as pointed above. Thus, a carbon dioxide cycle works in the atmosphere and its percentage remains nearly constant. However, over the years, Like methane, it also behave like a green bhouse gas and absorbs heat radiated by the earth. some of the heat is released into the atmoshphere while the rest is radiated back to earth. This has resulted in global warming over the years and has brough about major climatic changes.
