Glacier area changes in the Arctic and high latitudes using satellite remote sensing
ABSTRACTGlaciers have been retreating over the last century as a result of climate change, particularly in the Arctic, causing sea levels to rise, affecting coastal communities and potentially changing global weather and climate patterns. In this study, we mapped 2203 glaciers in Novaya Zemlya (Russ...
