The Upsala Glacier in Argentina's Los Glaciares National Park is pictured in this Sentinel-2A image from 22 January 2016.
The park was named a UNESCO World Heritage site in 1981 and is the largest in the country, covering an area of over 7000 sq km.
Many glaciers in the national park and in the wider Patagonian Ice Field have been retreating during the last 50 years because of rising temperatures. Upsala Glacier has retreated more than 3 km in the past 15 years.
Taking a closer look at the terminus of the Upsala Glacier, we can see how icebergs have broken off and are floating in the water of the upper reaches of Lake Argentino. The lake's unique colour is attributed to ‘glacier milk' – suspended fine sediment produced by the abrasion of glaciers rubbing against rock.
