World Day for Glaciers: Alarming signals also on Mount Everest

The world is increasingly becoming a glacier graveyard. In a study published at the end of February, scientists from 35 research teams determined that glaciers worldwide have lost an average of 273 billion tons of ice per year since 2000. An “alarming increase” has been recorded over the last ten years.

Michael Zemp, one of the co-leaders of the study, categorized the figure. “The 273 billion tonnes of ice lost annually amounts to what the entire global population consumes in 30 years, assuming three litres per person and day,” said the glaciologist from Switzerland.

The dramatic state of the glaciers can be observed worldwide. For example in the Alps, which scientists predict will be largely free of glaciers by 2100. Or in the polar regions, where temperatures are rising even faster than the global average and where the supposedly “eternal ice” is melting away like an ice ball in a waffle on a hot summer’s day. And also the region around Mount Everest, the highest mountain on earth, is no exception.

When the snow on Mount Everest disappears in winter

Be prepared for bare ice in the Western Cwm and on the Lhotse flank – and for wide crevasses! That’s what you could say to mountaineers who want to try to climb Mount Everest this spring.

“The lack of snow, as I reported last winter as well, will lead to crevasses being less filled/more open and more bare ice slopes,” Mauri Pelto writes to me. “This can be altered by late winter/early spring storms, but that is not to be expected.” In the 2024 Everest spring season, the scientist had already pointed out a lot of bare ice and firn slopes in the Western Cwm and in the Lhotse flank and thus an increased risk of falling rocks. The Khumbu Glacier is currently in a similar condition (see image below).
