Today’s Highlights
A study in Nature Communications presents the first physically consistent global map of terrain hidden beneath all glaciers on Earth. The analysis identifies over 50,000 potential future lakes that could form as glaciers retreat, with a combined volume equivalent to 7 mm of sea-level rise. Notably, large overdeepenings near glacier fronts in High Mountain Asia suggest elevated risks for glacier lake outburst floods under continued warming.

Glacier retreat transforms landscapes in polar and mountainous regions. Yet, the topography of the emerging terrain remains poorly known. Here, we present a physically consistent, global map of the ice-covered topography beneath all glaciers on Earth distinct from the ice sheets, derived from the three-dimensional higher-order Instructed Glacier Model, and constrained by extensive observational datasets. The map allows us to identify > 50,000 possible future lakes in the presently ice-covered landscape, with a maximum total volume of 3,138 km3—enough to store 7 mm sea-level equivalent (SLE). Additionally, we estimate the total global glacier volume at 149.41 ± 29.28 × 103 km3 (308 ± 60 mm SLE). Large overdeepenings near glacier fronts in High Mountain Asia suggest an increased risk for glacier lake outburst floods under glacier retreat. The subglacial topography and ice thickness data offer new opportunities for diverse cryospheric and Earth system studies, including refined projections of glacier changes and landscape evolution of deglaciated terrain.
