Glacier Intervention Research Isn’t Just for Glaciologists
Prospects for mitigating sea level rise by slowing flows of glacial ice into the ocean are worthy of research, but this work must involve all rights holders and stakeholders.
Warm Seawater Encroaches on Major Antarctic Ice Shelf
In unprecedented detail, new research illuminates the seasonal flow of warm water toward the Filchner-Ronne Ice Shelf.
Antarctic Ice Melt May Fuel Eruptions of Hidden Volcanoes
More than 100 volcanoes lurk beneath the surface in Antarctica. Ice sheet melt could set them off.
Massive Antarctic Icebergs May Calve at Random
The first analysis of extreme calving events in Antarctica finds no correlation with climate change, highlighting the significance of common, smaller calving events for ice loss and instability.
Cold Days Bring Fast Ice
Thirty-seven years of observations reveal the meteorological conditions that lead to persistent, thick fast ice in Antarctica.
Greenland Ice Sheet Stores Hidden Water Throughout the Melt Season
A new method uses stations around Greenland’s coast to measure how much meltwater weighs down the bedrock beneath the ice, improving our understanding of its contribution to sea level rise.
Mantle Motion Matters for Mapping Modern (and Ancient) Ice
Mantle motions have major effects on topography and the distribution of ice sheets. The motions are key for researchers trying to properly parse past mantle movement.
Another Hot Arctic Year Indicates a New Climate Regime
NOAA’s annual Arctic Report Card illustrates a warmer, wetter, and increasingly wonky Arctic climate.
Millions in India Vulnerable to Glacial Lake Floods
Climate change–driven factors make regions more vulnerable to glacial lake outburst floods.
