Crevasses are a feature of ice sheets but how deep they extend has been a mystery. Now crevasse traces have been visually identified to 265 meters in a borehole in a fast-moving outlet glacier.
Meltwater pulse 1A, a period of rapid sea level rise after the last deglaciation, was powered by melting ice from North America and Scandinavia, according to new research.
A new analysis of long-term satellite records shows the East Antarctic Ice Sheet is unexpectedly dependent on fluctuations in weather. This study may improve models of how much sea levels will rise.
A los científicos les preocupa que los modelos climáticos actuales no tomen en cuenta el impacto de las condiciones atmosféricas en la capa de hielo del Groenlandia, y en consecuencia, puedan subestimar drásticamente su derretimiento.
Researchers measure both grounded and floating ice sheets using satellite data spanning a 16-year period.
Scientists are concerned that current climate models do not fully account for the impact of atmospheric conditions on the Greenland Ice Sheet and, consequently, may dramatically underestimate melting.
New research reconstructing the topography of Antarctica shows that the continent has 25% less land above sea level than when ice first started to accumulate 34 million years ago.
Runoff from the Greenland ice sheet’s high elevations could double by 2100, thanks to solid layers of ice hiding just beneath the surface.
East Antarctica’s lakes cluster in patterns similar to those on Greenland’s ice sheet, which is melting rapidly.
Ancient Arctic artifacts are disappearing as warming unfurls.
