Glacier changes


Bolch, Tobias (2017). Glacier changes. In: Richardson, Douglas; Castree, Noel; Goodchild, Michael F; Kobayashi, Audrey; Liu, Weidong; Marston, Richard A. The international encyclopedia of geography : people, the earth, environment, and technology. Hoboken: Wiley-Blackwell Publishing, Inc, online.

Abstract

Glaciers are naturally subject to changes in line with the Earth's climate variability. Area and length changes of glaciers which are not influenced by debris cover, calving, or dynamic instabilities show a filtered and delayed climate signal while the glacier mass balance can be more directly linked to climate. Glaciers retreated on average strongly since the end of the Last Glacial Maximum about 19 000 years ago with several periods with glacier advances especially during the Holocene. Clearly visible moraines of the Little Ice Age indicate the maximum glacier extent occurring between the seventeenth to the late nineteenth century. The glaciers retreated again strongly and lost mass since then with an accelerated rate since the 1980s. However, glacier changes are not homogeneous throughout the globe but local deviations and even regions with stable glacier conditions exist. Further significant reduction of glacier mass is projected for the twenty-first century.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
