Let me try that #1 again:

No. Again, you're equating absorption with heating; ...but to answer the suggestion:
In the real world (and not a 1 cm cuvette), it'd just be absorbed farther away, where CO2 wasn't already excited (to extinction).

Better?

Pyrolysis creates reduced carbon! ...Time for the next step in our evolutionary symbiosis with fire.
