“East Antarctica has long been thought to be less threatened (than West Antarctica), but as glaciers such as Denman have come under closer scrutiny by the cryosphere science community, we are now beginning to see evidence of potential marine ice sheet instability in this region,” said study co-author Eric Rignot, a scientist at the University of California-Irvine. Richard Alley, a Penn State University glaciologist who was not involved in the study, told The Washington Post that “this study provides additional evidence that, based on current knowledge, we cannot exclude at least a slight possibility of much more sea-level rise than the most-likely value in (Intergovernmental Panel on Climate Change) projections.". A large swath of ice might be on the verge of breaking off of Antarctica and drifting off into the sea, according to Sky News. National Oceanic and Atmospheric Administration. The glacier acts as a buffer between the warming sea and other glaciers. After their assessment of the Denman Glacier, "East Antarctica has long been thought to be less threatened," Eric Rignot, who co-authored the team's study "Geophysical Research Letters," said in a.
