They are finally talking about water vapor. Carbon dioxide is nothing compared to it.

Plus the water vapor rises more easily than CO₂. A moloecule with two hydrogen atoms and one oxygen atom is considerebly lighter than O_{2 or N2 (oxygen and nitrogen respectively) and its part of the reason why moisture laden air rises and convection works. (heat transfer is the other part of it).}

Water also has a high specific heat, meaning it can hold more thermal energy, per unit of its weight. That's why our oceans make such a good heat sink. Water can absorb heat without its own temperature rising as much as most other substances, due to its hydrogen bonds.

All models of GHG-induced global warming include water vapor feedback. If they didn't, they wouldn't work.
