And that heat absorbed is warming it's surroundings, namely the planet earth, the land and the sea and the sky.
We pump CO2 into the atmosphere, like the burning of gasoline:

C8H18 + O2 --> H2O + CO2

See that CO2 on the right (output) side of the equation, that is "matter (CO2) present at an altitude" as you say. And those molecules near the glaciers will warm those glaciers, and those now-cooler CO2 molecules will absorb heat from CO2 layers a little further up, and so on and so forth.

Great to see you understand climate change now.

I've understood it since it appeared to be cooling off in a big way. What seems to be missing from your understanding is that increased absorption leads to increased emission (even at constant T).
