| Zusammenfassung |
| In the upper atmosphere, greenhouse gases produce a
cooling effect, instead of a warming effect. Increases in greenhouse gas
concentrations are expected to induce substantial changes in the mesosphere,
thermosphere, and ionosphere, including a thermal contraction of these
layers. In this article we construct for the first time a pattern of the
observed long-term global change in the upper atmosphere, based on trend
studies of various parameters. The picture we obtain is qualitative, and
contains several gaps and a few discrepancies, but the overall pattern of
observed long-term changes throughout the upper atmosphere is consistent
with model predictions of the effect of greenhouse gas increases. Together
with the large body of lower atmospheric trend research, our synthesis
indicates that anthropogenic emissions of greenhouse gases are affecting the
atmosphere at nearly all altitudes between ground and space. |
