Almost immediately (nanoseconds) they relax from their excited state by either 1) emitting that energy as a new photon, some of which will continue up towards space, some of which will go back downward to be reabsorbed, thus keeping the energy in the atmosphere longer, or 2) by colliding with another gas molecule, most likely an O2 (oxygen) or N2 (nitrogen) molecule since they make up over 98 % of the atmosphere, thereby converting the extra vibrational energy into kinetic energy by transferring it to the other gas molecule, which will then collide with other molecules, and so on, making the air warmer.

@Jimbo — If you really want to put it in perspective, until about 2 to 1-1/2 billion years ago, before photosynthesis by blue - green algae converted almost all of it to oxygen, the Earth's primordial atmosphere was about 20 percent CO2, about the same percentage as oxygen is today, and the Earth certainly didn't burn up them even with 500 times as much CO2 in the air as there is today.

Sensible heat losses can be reduced by installing improved combustion controls to allow fine - tuning the excess air level in the furnace operators to reduce the excess oxygen level in the furnace.
