Figure 2.18: A collection
of twenty glacier length records from different parts of the world. Curves have
been translated along the vertical axis to make them fit in one frame. The geographical
distribution of the data is also shown, though a single triangle may represent
more than one glacier. Data are from the World Glacier Monitoring Service (http://www.geo.unizh.ch/wgms/)
with some additions from various unpublished sources.
