... · The atmospheric accumulation of greenhouse gases has led to cooling of the stratosphere. This, in turn, may prolong the recovery of the stratospheric ozone layer, since colder winters and more stable polar vortices generally increase polar ozone losses (Shindell et al., 1998~.

... Changes in the thermal structure of the troposphere and stratosphere may also affect the location of the tropopause and cross-tropopause transport of ozone and its precursors (IPCC, 1996~.1 Impacts of Climate Change on Emissions of Greenhouse Gases and Aerosol/Ozone Precursors . Climate can affect the emissions of many biogenic compounds that play an influential role in tropospheric chemistry.

... Large-scale changes in OH, in turn, affect the lifetime and thus the atmospheric abundance of reactive greenhouse gases such as CH4, HFCs, and HCFCs. The preceding list is not a comprehensive description of all the potentially important linkages between climate and atmospheric chemistry; it is only meant

... Improving our understanding of the interactions between climate and air quality will depend primarily on developing more sophisticated modeling tools; in particular, it will require the ability to couple local- and regional-scale air quality models (which cover spatial scales of a few hundred meters to hundreds of kilometers) with global-scale climate and chemistry models.
