  • In recent years, rivers and slush fields have often developed on top of near-impermeable ice slabs in the accumulation zone of the Greenland Ice Sheet. Measurements of superimposed ice formation and melting reveal that ice slabs are both hotspots of refreezing and emerging zones of runoff.

  • We link long-term mass loss of Patagonian glaciers to a poleward shift of subtropical high-pressure systems. This phenomenon brings more warm air to Patagonia, enhancing glacier melt. Since 1940, Patagonian glaciers have raised sea level by 3.7 mm.

  • Most of the meteorites on the Earth’s surface are found in Antarctica. Here the authors show that ~5,000 meteorites become inaccessible per year as they melt into the ice due to climate change.

  • The authors develop a machine learning-based approach to derive abrupt shift probability in dryland ecosystem functioning in the Sudano–Sahel. They highlight areas with high probabilities of abrupt shifts in the near future (2025), which are linked to long-term rainfall trends.

  • Melt ponding is an important process for the stability of ice shelves. Here the authors estimate the temperature thresholds at which melt ponding emerges over Antarctic ice shelves and find that cold and dry ice shelves are more vulnerable to melt ponding than expected.

  • 14% of the world’s coastlines are muddy and the majority of them are eroding at rates exceeding 1 m per year over the last three decades, according to an automated classification method that identifies global coastlines.

  • High-resolution 2-km Antarctic maps reveal higher snowfall and surface melt than low-resolution products, reconciling satellite-observed ice sheet mass change. Projected higher surface melt near grounding lines threatens future ice shelf stability.

  • Thunderstorm activity over Lake Victoria poses a threat to human life, yet little is known about their evolution under climate change. Here, using satellite observations and high-resolution modelling, the authors project an increase in precipitation extremes over Lake Victoria, twice that of surrounding land.

  • A firn layer covers the Earth’s ice sheets. This Review outlines techniques to observe and model changes in firn properties and meltwater retention to understand how this firn layer will respond to climate change.
