Iceland’s glaciers are rapidly shrinking due to recent warming temperatures. Sólheimajökull is well-known for its accessibility as a location for tourist glacier hikes. The glacier has changed drastically in the last 20 years, with a meltwater lake forming around 2009. The glacier is now in contact with deep, open water, which causes icebergs to break off, which can accelerate the shrinking of the glacier. The University of Iceland’s glaciology students have annually measured the surface ice melt since 2013. This study aims to compile this data with other datasets collected from the glacier, including terminus measurements, elevation change, ice flow velocity, and lake surface area to evaluate the overall changes to the glacier and the surrounding environment. The overall glacier evolution reveals that terminus has retreated 60 meters per year, the lake surface area has nearly quadrupled, and the glacier surface has melted about 6 cm (water equivalent) per day in the summer and 1 cm (water equivalent) per day in the winter. These changes raise concerns about the future of the glacier as it continues to retreat up the valley. The overall state of glacial retreat has immense societal importance for Iceland.
