English: The three months from May to July 2020 have been the warmest on record for the Northern Hemisphere. As a consequence of the high temperatures, Arctic sea ice extent is currently the 3rd lowest on record. Arctic ice caps have also been affected by the effects of high temperatures at high latitudes. As reported by the Laboratory of Climatology and Topoclimatology of the Liege University, the ice caps of Svalbard, Franz Joseph Land and Russian High Arctic Islands, have seen their extension diminish at record speed compared to previous years. This image, acquired by one of the Copernicus Sentinel-2 satellites on 15 August 2020, shows the ice cap of Komsomolets island (Russian High Arctic Islands). The extension of the ice cap as imaged by Copernicus Sentinel-2 satellites in September 2016 is also shown, for comparison purposes. The comparison allows to estimate the retreating of the ice cap to 120 m on average from 2016 to 2020. The Copernicus Sentinel satellites are particularly useful for monitoring the impact of climate change in the Arctic region.
