The document discusses the retreat of Alpine glaciers in Charmonix, France due to warmer temperatures over the last two decades. This rapid glacial retreat, with some glaciers losing over 100 meters per year, has caused the high alpine snowline to rise dramatically. As a result, the high alpine environment in Charmonix is changing quickly, with observable impacts even over a short period of time.

8. RETREAT
CAUSES
Recently the retreat of Alpine glaciers has been
increasing dramatically with some glaciers losing
over 100m of their length per year. The warmer
temperatures of the last two decades resulted in a
dramatic increase of the average snowline. Thus,
the high alpine environment is changing rapidly
with observable changes even within a relatively
short time period.
