Sebastian Bathiany coauthored an analysis explaining why increasing carbon dioxide can cool the middle atmosphere while contributing to warming elsewhere. The work compares radiative regimes rather than treating a gas as having one temperature effect independent of its surroundings.^[ref]

The physical interpretation depends on the balance of absorbed and emitted radiation, the atmospheric structure and the level at which energy escapes. This is a concrete application of radiative transfer to climate.
