"Combined with the unusually high temperatures across the region over the summer, glaciers are melting fast."
In addition to those killed, at least eight people were injured by the collapse, which happened near a popular climbing route, and 14 were still missing as of this writing. "High elevation glaciers such as the Marmolada are often steep and relying on cold temperatures below zero degrees Celsius to keep them stable," he explained."But climate change means more and more meltwater, which releases heat that warms up the ice if the water re-freezes, or even worse: lifting up the glacier from the rock below and causing a sudden unstable collapse."
