  • 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.

  • It is assumed that the monsoon is the dominant influence on Himalayan glaciers. However, a study now investigates the importance of the mid-latitude Westerlies and shows that glacier changes can be triggered from afar.

  • Ice that melts at high elevation often refreezes and, therefore, does not contribute to the shrinking of ice sheets. Here, the authors show that the elevation at which melting ice starts to contribute to runoff has increased over recent years in Greenland, expanding the runoff area by 29%.

  • Surface melt of the Greenland ice sheet is retained through storage in the surface porous ice. This study shows that successive melt events have caused the formation of near-surface ice layers, preventing this storage and increasing meltwater runoff.

  • The ice volume of glaciers outside the Greenland and Antarctic ice sheets totals about 158,000 km3, with about 27% less ice in High Mountain Asia than thought, according to multiple models that estimate ice thickness from surface characteristics.
