D. global warming produced by the excess amount of `CO_(2)` in the atmosphere

Answer

D

Explanation

Many small molecules in the atmosphere, particularly `H_(2)O` and `CO_(2)`, absorb certain wavelengths of the escaping radiation from earth's surface. Thus, these small molecules act like glass in a green house. It is the re-radiation of their absorbed energy back to the earth that warms the oceans, land, and air.
