In the heart of Switzerland, the Aletsch is the largest glacier in the Alps. In recognition of its importance and unique characteristics, it was declared a UNESCO World Heritage Site in 2001.
However, climate change is threatening its very existence. According to a new study published in the scientific journal The Cryosphere, it could lose about half of its current volume by 2100 as a result of a 1°C increase in the planet's average temperature.
This three-dimensional visualisation of the image acquired by one of the Copernicus Sentinel-2 satellites on 15 June 2021, shows the Aletsch Glacier.
With an average revisit time at the equator of five days, the Copernicus Sentinel-2 satellites provide crucial data that is used to monitor the impact of climate change and its consequences on alpine environments.
