Internationale Forschende unter Beteiligung der TU Graz legen eine weltweite Bilanz des Eisrückgangs seit Beginn des Jahrtausends vor. Die Gletscher der Alpen und Pyrenäen schmelzen im globalen Vergleich am schnellsten.
Reference glacier sites with systematic in situ monitoring provide crucial information to understand trends in regional change. Throughout Central Asia, several sites have been established over the past 15 years, often restarting long-term time series interrupted after the Soviet Union’s collapse.

Glaciers are indicators of ongoing anthropogenic climate change1. Their melting leads to increased local geohazards2, and impacts marine3 and terrestrial4,5 ecosystems, regional freshwater resources6, and both global water and energy cycles7,8. Together with the Greenland and Antarctic ice sheets, glaciers are essential drivers of present9,10 and future11,12,13 sea-level rise.

The flow speeds of floating ice shelves around the Antarctic Ice Sheet exhibit clear intra-annual variability. However, the drivers of this variability remain poorly understood. Here, we present three new velocity datasets from Global Navigation Satellite System (GNSS) stations on the Ross Ice Shelf collected between early 2020 and late 2021 and show that they have two distinct peaks observed in austral summer and austral winter.

The Highly Cited Researchers 2024 list identifies and celebrates individuals who have demonstrated significant and broad influence in their fields of research. Tobias Bolch has been identified as “Highly Cited Researcher” in the field “Geosciences” Web of Science/Clarivate Analytics. In 2024, about 0.1 % of the World’s researchers in 21 research fields and across multiple fields, have earned this exclusive distinction. Only about 175 researchers were identified in the field of Geosciences.
The photographs taken by the US Air Force offer a unique opportunity to analyse the state of Austrian glaciers on a large scale after the end of the Second World War. Read more …
Tobias Bolch has been identified as “Highly Cited Researcher” in the field “Geosciences” Web of Science/Clarivate Analytics. In 2023, about 0.1 % of the World’s researchers in 21 research fields and across multiple fields, have earned this exclusive distinction.

In this study, we evaluate the suitability of very-high-resolution Pléiades digital elevation models (DEMs) to measure glacier mass balance at annual and seasonal scales in two regions of High Mountain Asia (Muztagh Ata in Eastern Pamirs and parts of western Nyainqêntanglha, south-central Tibetan Plateau)
