[PP05] Changes in glacier extent
[PP05] Changes in glacier extent
Key message
From the year 1982 onwards the shrinking of the glacier was more intense. Due to intensive thinning the extent of outcoropping rocks increased so much that the glacier disintegrated into several parts. In the first decade of the 21st century we can observe stagnation of the glacier. Last major recession of the glacier was registered after the above average hot summer of 2003. In most of the following years the snow on the glacier had not melted by the beginning of the next accumulation season.
