Scientists from the Oregon State University conducted chemical analyses on air bubbles trapped within the West Antarctic Ice Sheet Divide ice core. They discovered that, in the la ...

The lingering Laurentide Ice Sheet may have masked the true extent of Antarctic ice loss—offering a warning for future change. 100% = global mean sea level rise; areas above saw higher-than ...

An Ice sheet is a mass of glacier ice that covers surrounding terrain and is greater than 50,000 square kilometers ... (LGM) the Laurentide ice sheet covered much of Canada and North America, ...

Reconstruction of the activity of ice streams operating during the retreat of the Laurentide Ice Sheet reveals that the number of ice streams and their total discharge decreased as the total ...

The Stokes paper examines the Laurentide Ice Sheet, which covered much of North America until about 10,000 years ago. The study presents a historical reconstruction of how ice streams behaved as the ...

The Laurentide Ice Sheet hasn’t quite melted all the way. The Barnes Ice Cap, in the middle of Baffin Island in northern Canada, is all that remains of a sheet that once covered hundreds of ...

In the 2.5 million years that Earth’s climate moved between ice ages and milder periods, the Laurentide Ice Sheet expanded and retreated, shaping modern-day existence in the Midwest.

The new study—published today in the journal Nature and co-authored by researchers at the University of Bristol, University of Washington and UC Berkeley—suggests that substantial reduction of the ...
