Glaciers at excessive, steep elevations such because the Marmolada depend on temperatures under zero levels Celsius “to maintain them steady”, stated Poul Christoffersen, professor in glaciology on the College of Cambridge.

“However local weather change means an increasing number of meltwater, which releases warmth that warms up the ice if the water re-freezes, and even worse: lifting up the glacier from the rock under and inflicting a sudden unstable collapse,” he stated.
