The persistence of Perito Moreno
Yes, it's true that glaciers are shrinking, but not all of them. Perito Moreno, a low-lying glacier in southern Argentina, accumulates ice at about the same rate that it melts into chilly Argentino Lake. This equilibrium makes it one of the few glaciers worldwide that aren't losing mass to climate change.
Perito Moreno is an Argentine icon, partly for its unusual accessibility via the lake, the largest within the nation. Visitors to Los Glaciares National Park can boat or kayak out on ice-blue water for a better look—but they need to keep a safe distance as icebergs constantly calve from the glacier's face, creating huge splashes and waves.
