At least seven people were killed after a large chunk of a mountain glacier collapsed in the Italian Alps (Dolomites).

Eight injured and about 20 missings, authorities said. The avalanche of snow, ice, and rocks hit a group of alpinists who were rope climbing on Marmolada, the highest mountain in the Dolomites. Italian Prime Minister Mario Draghi expressed his “deepest condolences” to the families of the victims, whose identities were not yet known.
Mountain experts said the Marmolada accident was the biggest of its kind in the Alps in decades. They noted that record-high temperatures in recent days could have contributed to accelerating the melting of the ice, but added that many factors are at play.
According to studies by Italy’s state-run CNR research center, the glacier will not exist anymore in the next 25-30 years and most of its volume is already gone due to the effects of global warming.
