An informational graphic titled Copernicus In Situ Use Case Story, Svalbard: A Sentinel of Climate Change. The left side features a dark teal background with white text and logos for the European Union, Copernicus, and the European Environment Agency. The right side shows a high-contrast photograph of a research team in dark Arctic gear standing in a vast, snowy white landscape during a snowfall. A call to action at the bottom invites viewers to explore how the Norwegian archipelago is shaping our understanding of the Arctic and the globe.
#Svalbard is a sentinel of the climate crisis. Monitoring its record ice loss requires both #CopernicusEU #Sentinel satellites and ground data to ensure accuracy.
