A. Berger: Long-term climate change model prediction and the role of ice sheet.

Stratosphere:
D. Kley: Assesment of water vapor in the upper troposphere and stratosphere (SPARC WAVAS)
V. Ramaswamy: Forced and unforced variations of stratospheric climate: An evaluation based on observations and model simulations.
M.-L. Chanin: Long term trends and solar influence in the stratosphere.
C. Zerefos: An update of long-term changes in ozone and UV-B.
J. Staehelin: Long-term ozone trends with special emphasis to contribution of changes in dynamics.

Mesosphere and lower thermosphere (MLT - below 100km):
G. Thomas: Water vapor trends - state of art, progress report on assessment.
G. Beig: Temperature trends - state of art, overview, progress report on assessment.
J. Lastovicka: Trends in the lower ionosphere (ionized components) and inferred planetary wave activity and temperature trends.
F.-J. Luebken: Temperature trends in the mesosphere at middle and high latitudes: recent results from experiments and modelling.
T. Ulich: Trends in riometric absorption in auroral zone and polar cap
A.I. Semenov: The seasonal peculiarities of behaviour of the long-term temperature trends in the middle atmosphere.
D. Marsh: Trends in mesospheric ozone and interactions with water vapor trends
R.A. Akmaev:  Modeling the cooling due to CO2 increase in the mesosphere and lower thermosphere.

Ionosphere and thermosphere (above 100km):
G. Keating: Trends in thermospheric density.
A.D. Danilov: Assessment or overviw of trends in F (? and E) region parameters.
T. Ulich and E. Turunen: Trends in F2 region parameters - careful determination.
A.A. Michajlov: Geomagnetic control of the F2-layer parameter trends.Ionosphere and thermosphere (above 100 km):
J. Bremer: Trends in the ionospheric E and F1 regions and in the mesopause region winds.

"Round table" discussions:
Two are quite evident due to different results and points of view:
1. Trends in F2 region parameters.
2. Trends in mesospheric (MLT) temperature.
3. Trends in minor components (water vapor, NO, ozone).
4. Anthropogenic versus natural origin of trends and long term changes.
