Sermeq Kujalleq is a large glacier located in southwestern Greenland. It is known for being one of the fastest-moving glaciers in the world, with a significant rate of ice flow. The glacier feeds into the Jakobshavn Isbræ, which is a major outlet glacier of the Greenland Ice Sheet. The melting of Sermeq Kujalleq has raised concerns about rising sea levels, as it contributes to the overall loss of ice in Greenland. Scientists study this glacier to understand the impacts of climate change and to predict future changes in ice dynamics and sea level rise.
