PERITO MORENO, ARGENTINA – APRIL 5: Broken ice floats in Lake Argentina below the cracked and creviced face of the Perito Moreno glacier, part of the Southern Patagonian Ice Field, in the Los Glaciares National Park on April 5, 2019 in Santa Cruz province, Argentina. The ice fields are the largest expanse of ice in the Southern Hemisphere outside of Antarctica but according to NASA, are melting away at some of the highest rates on the planet as a result of Global Warming.
