European glaciers constitute a part of the climate system that is bound to greatly change in the course of the 21st century. Recent length-change observations from Langfjordjøkelen in northern Norway confirm the earlier predictions of Charalampidis (2012), who identified the glacier’s disequilibrium with climate and hence extensive committed ice loss in the 21st century. Simulations suggest that, over the 2026–2050 period, the glacier outlet will continue adjusting its geometry with a rate of retreat of ~33 m a-1 for a moderate regional precipitation increase in a warming climate, and with regional climate variability in the context of a warming Arctic only augmenting the persistent retreat. The glacier outlet of Langfjordjøkelen is predicted to eventually split in two parts due to substantial retreat and thinning sometime in the 2050s.
