| description | Glacier fluctuations contribute to variations in sea level and historical
glacier length fluctuations are natural indicators of past climate change. To
study these subjects, long-term information of glacier change is needed. In
this paper we present a data set of global long-term glacier length
fluctuations. The data set is a compilation of available information on
changes in glacier length worldwide, including both measured and
reconstructed glacier length fluctuations. All 471 length series start before
1950 and cover at least four decades. The longest record starts in 1535, but
the majority of time series start after 1850. The number of available records
decreases again after 1962. The data set has global coverage including
records from all continents. However, the Canadian Arctic is not represented
in the data set. The available glacier length series show relatively small
fluctuations until the mid-19th century, followed by a global retreat. The
retreat was strongest in the first half of the 20th century, although large
variability in the length change of the different glaciers is observed.
During the 20th century, calving glaciers retreated more than
land-terminating glaciers, but their relative length change was approximately
equal. Besides calving, the glacier slope is the most important glacier
property determining length change: steep glaciers have retreated less than
glaciers with a gentle slope. |
