Vestari Hagafellsjökull, on the south side of Langjökull, has retreated about 200 meters since 2023, according to a preliminary glacier-terminus survey conducted on 20 September 2025. Since 2009 the glacier has receded roughly 973 meters through 2023, with accelerated retreat likely tied to this summer’s warmth.
A sudden glacial outburst flood from a marginal lake near Langjökull sent water into the Svartá and downstream into the Hvítá in Borgarfjörður, peaking above 400 cm overnight before easing to just over 300 cm. Authorities warn further river flooding is possible in coming days, with increased landslide risk in southeast Iceland.
July 2025 tied with 1933 as Iceland’s warmest July on record, with northeast and east regions averaging up to 14.2 °C and widespread 20 °C days across the country.
Icelandic glaciers have been losing mass since the Little Ice Age, but that process has slowed over the last decade thanks to the influence of what scientists have dubbed the Blue Blob, “an area of regional cooling in the North Atlantic Ocean to the south of Greenland.
The land around Höfn in Hornafjörður is rising rapidly due to the melting of the glaciers in the surrounding area. There, the land is rising one centimetre per year,
A series of photos, taken by Guðmundur Ögmundsson, Skaftafell National Park manager in the past five years, shows in a striking way how Skaftafellsjökull glacier, an outlet glacier from Vatnajökull glacier, has receded.
