Nov. 7, 2018 — Researchers recently assessed subglacial lakes detected by satellite, and found very little water. But if that's the case, what is the source of the East Antarctic Ice Sheet's massive ice ... read more

Investigating Glaciers in Depth

Oct. 24, 2018 — Global sea level is rising constantly. One factor contributing to this rise is the melting of the glaciers. However, although the surface area of the glaciers has been well mapped, there is often no ... read more

Oct. 23, 2018 — Many of the plants inhabiting northern mountains depend on the snow cover lingering until late spring or summer. Snow provides shelter for plants from winter-time extreme events but at the same time ... read more

Oct. 17, 2018 — A new collaborative study has investigated Arctic shrub-snow interactions to obtain a better understanding of the far north's tundra and vast permafrost system. Incorporating extensive in situ ... read more

Oct. 16, 2018 — Winds blowing across snow dunes on Antarctica's Ross Ice Shelf cause the massive ice slab's surface to vibrate, producing a near-constant set of seismic 'tones' scientists could ... read more

Oct. 15, 2018 — A new method for observing water within ice has revealed stored meltwater that may explain the complex flow behavior of some Greenland glaciers, an important component for predicting sea-level rise ... read more

Changes in Polar Jet Circulation Bring More Dust from Sahara Desert to the Arctic

Oct. 10, 2018 — Poleward transport of warm, moist, and dust-laden air masses from the Sahara Desert results in ice melting in southeast Greenland, scientists have ... read more

Oct. 9, 2018 — Antarctica's sandy polar desert, the McMurdo Dry Valleys, has undergone changes over the past decade and the recent discovery of thawing permafrost, thinning glaciers and melting ground ice by a ... read more

Oct. 3, 2018 — Leaf fossils discovered high in Australia's Snowy Mountains have revealed a past history of warmer rainforest vegetation and a lack of snow, in contrast with the alpine vegetation and winter ... read more

Sep. 27, 2018 — Arctic sea ice likely reached its 2018 lowest extent on Sept. 19 and again on Sept. 23, 2018. Analysis of satellite data showed that, at 1.77 million square miles (4.59 million square kilometers), ... read more

Sep. 26, 2018 — The effects of climate change are behind an increase in plant height across the Arctic tundra over the past 30 ... read more

Sep. 25, 2018 — More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice -- ice that ... read more

Sep. 21, 2018 — Scientists have found that additional weather observations in the Arctic can help predict the track and intensity of tropical and mid-latitude cyclones more accurately, improving weather forecasting ... read more

Sep. 20, 2018 — Targeted engineering projects to hold off glacier melting could slow down ice-sheet collapse and limit sea-level rise, according to a new study. While an intervention similar in size to existing ... read more

Sep. 19, 2018 — Using observational and model-based data spanning the entire 20th century, scientists have for the first time have identified three broadly-categorized processes responsible for Earth's spin ... read more

Sep. 19, 2018 — In the last few years, the Vavilov Ice Cap in the Russian High Arctic has dramatically accelerated, sliding as much as 82 feet a day in 2015, according to a new multi-national, multi-institute study. ... read more

Sep. 19, 2018 — Parts of the world's largest ice sheet would melt if Antarctic warming of just 2°C is sustained for millennia, according to international research. Scientists used evidence from warm periods in ... read more

Sep. 6, 2018 — Evidence left by a volcano under the ice sheet suggests that the observed bulging of ice in West Antarctica is a short-term feature that may not affect the glacier's motion over the long ... read more

Sep. 4, 2018 — New research indicates that what future precipitation California gets will be pretty much limited to the winter months -- think deluge-type rainfall rather than snow -- and non-winter months will be ... read more

Sep. 4, 2018 — Accurate projections of sea level rise require sophisticated models for glacier flow, but current approaches do a poor job capturing the physical processes that control how fast glaciers slide over ... read more
