CO2 Absorption Spectrum.

Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of wavelengths, which are , and 15 micrometers (µM). This means that most of the heat producing radiation escapes it. About 8% of the available black body radiation is picked up by these "fingerprint" frequencies of CO2. Several decades ago, before global warming was an issue, scientists concluded that carbon dioxide ...
