= Stratospheric cooling by carbon dioxide
An increase of atmospheric <carbon dioxide> can cool the <stratosphere> through enhanced infrared cooling relative to non-infrared heating and through changes in the spectrum of upwelling radiation. A local emissivity-only explanation is incomplete because absorption and emission both change. The response depends on <ozone> solar heating, spectral opacity, altitude and adjustments of the layers below.<Why CO2 cools the middle atmosphere - a consolidating model perspective by Helge F.
