In climate system science, the anthropogenic influence on our planet is most obvious for the global state of the climate. Adaptation to the climate of the future, however, requires information at regional and local levels ("scales"). This necessity implies the need to understand the processes that transmit global impacts to various regions. The presentation demonstrates how the prominent climate change signal of glacier loss in high mountains and cold regions allows us to decipher a complex chain of processes: coupled atmosphere-ocean modes acting over thousands of kilometers; associated flows in the atmosphere that are strongly modified upon collision with the mountains; and the meteorological conditions on their summits which provide the local environment for glacier variability. This interplay offers a key to comprehend the three-dimensional functioning of the climate system – through different space-time scales and from the surface up to higher air layers (the mid troposphere).
