The Sermeq Kujalleq glacier, entering the Kangia Ilulissat Icefjord full of icebergs, August 2019. Sermeq Kujalleq is one of the world’s most productive glaciers and the fastest moving one in the world. Within the past 10 years, the glacier has doubled its speed and today it moves about 40 metres every 24 hours. This is because ice from a very large drainage area is concentrated in a narrow stream that follows a deep trough under the glacier. Scientists also believe that rising temperatures result in increasing amounts of meltwater under the glacier. (Photo by Michel Roggo/naturepl.com/LDY Agency)
