  • Changes in glacier speed in High Mountain Asia are closely linked to mass balance through gravitational driving stress, and largely insensitive to basal conditions, according to satellite-derived ice-flow observations.

  • This study explores the 90-year collapse of the Midgaard Glacier, one of the greatest mass losers in the entire Greenland ice sheet. The study reveals complex ice flow piracy and demonstrates the impact of Midgaard’s collapse on the dynamics of glaciers at a regional scale.

  • Glaciers in High Mountain Asia are a key water resource. The authors use remote sensing data and a regional implementation of the continuity equation to quantify glacier ablation and accumulation rates for 2000–2016, and establish current climatic-geometric imbalances that imply strong reductions in ice volume by 2100.

  • Whether or not an increase in meltwater will make ice sheets move more quickly has been contentious, because water lubricates the ice–rock interface and speeds up the ice, but also stimulates the development of efficient drainage; now, a long-term and large-area study of a land-terminating margin of the Greenland Ice Sheet finds that more meltwater does not equal higher velocity.

  • Glaciers in the Karakoram region, with their balanced or slightly positive mass balance, stand out from global glacier shrinkage, but this anomaly is not expected to persist in the long term, according to an overview of the possible explanations.
