This paper deals with possible effects of rising CO2 and temperature on alpine vegetation. Present carbon dioxide concentrations still limit photosynthesis in most plant species, and a higher degree of limitation can be anticipated for plants living
under reduced atmospheric pressure at high altitudes. High altitudes plants are therefore particularly suited for early warning components of a comprehensive global monitoring effort on vegetation change. This recommendation is also warranted by the fact
that alpine vegetation is unique in being present at nearly all latitudes of both hemispheres.
