We’ve all heard of glacial retreat. But have you heard of this glacier in Argentina that keeps collapsing?
Take a look at this BBC video of the Perito Moreno glacier in the country’s Patagonia region, where a part of the glacier recently collapsed. This event is, thankfully, not due to climate change. Rather, its part of an unusual cycle of an advancing glacier, slowly damming a section of the Argentino Lake, creating an ice bridge, which then ruptures and collapses when the water pressure becomes too great. This collapsing spectacle is part of a natural cycle that can occur once a year or sometimes less frequently, around once a decade.
Even though this collapse may not be due to climate change, scientists do say that overall the amount of glacial ice in the Patagonia region is decreasing.
