Global atmospheric chemistry and its role in climate change
- Lawrence Livermore National Lab., CA (USA)
The direct radiative forcing on the atmosphere that results from any given amounts of CO{sub 2} and other trace gases is generally well understood. However, the magnitude of climate change that could result is still highly uncertain, largely due to remaining uncertainties in climate feedback processes. In addition to direct radiative effects of surface-emitted gases, there are indirect effects on climate that need to be considered. Atmospheric chemistry plays a key role in the determination of many of these effects. The actual atmospheric composition of the greenhouse gases will depend not only on natural and anthropogenic surface emissions, but also on any atmospheric chemical processes affecting their concentrations and distributions. These photochemical processes are often coupled and nonlinear. Because of this, the net climatic impact of changes mediated by photochemistry tends to be specific to the detailed scenario assumed for trace gas abundance and emission trends.
