Chilean explorer and photographer Cristian Donoso followed in the footsteps of early 20th century missionary, Alberto de Agostini, to recreate his images of Patagonia's glaciers taken over a century ago. His photographs reveal how climate change has melted the glaciers. De Agostini left an archive of 11,000 images of Patagonia. This one, taken in 1914, shows the Marinelli glacier in Tierra del Fuego's Ainsworth Bay.
