TROPICAL GLACIERS
Georg Kaser, Henry Osmaston
Cambridge University
Press, 2001
228 pp, b/n
Tropical glaciers are both highly sensitive
indicators of global climate and fresh water reservoirs in some fast
developing regions. This book gives a theoretical and practical
analysis of tropical glaciology including a useful definition of
tropical glacier-climate regimes and the analysis of the main
glaciological key variables. The Rwenzori and the Cordillera Blanca
are investigated as examples of tropical glacierized mountains. The
fluctuations of their glaciers since the end of the Little Ice Age
are reconstructed and the probable climatic reasons are discussed.
The evidence of great expansions of mountain glaciers throughout the
tropics on several occasions during the Quaternary are summarised,
examined and then applied and contrasted. The accompanying map of
the Rwenzori Mountains National Park at a scale of 1:100,000 shows
the spectacular retreat of the glaciers during the last century, and
their extensions over half the area of the Park in the last 300,000
years.
