If CO2 traps heat, does it also prevent heat from the Sun from getting to Earth in the first place?
How does the molecule know which direction the heat is coming from?
Solar energy is mostly in the UV spectrum, which is not absorbed by CO2. Radiant energy form the Earth is in the IR spectrum, which is absorbed by CO2.

Star navigation?
Only moisture and blanket cloud cover can absorb and develop the kind of warming they talk about. CO2 does not even condensate nor reflect/trap infrareds like clouds do.
