"What we want to do now is work out how fast the glaciers are flowing and how deep they are."

"All we have done is a quick health check," Stokes said. The scientists hope that, in the future, they will be able to more closely assess these dynamics by culling together and examining other available satellite and climate data. As a result, the interplay of climate and glacial patterns remains relatively poorly understood. Since East Antarctica is so isolated and difficult to access compared with coastal regions of West Antarctica and areas around the North Pole, fewer climate monitoring stations have been established there, and less data is available on ice sheet dynamics in the region. Future warming could, however, push the region into a more significant retreat phase that could potentially cause net reduction in ice thickness in the region, Stokes said. While the researchers did note periods of growth and retreat, they did not detect a notable net change in the size of the ice sheet during the study period. "So the concern would be that if it does start to get warmer, then we would expect to see the glacier retreat." "We've shown for the first time that these glaciers are in concert with climate," Chris Stokes, a professor of geography at Durham University and an author of the paper, told LiveScience. United States Geological Survey Earth Resources Observation Science Center These panels show satellite imagery of Vanderford Glacier, Wilkes Land, East Antarctica. The team has found that periods of expansion and retreat of the ice sheet's glaciers, essentially rivers of ice, appear to correspond with periods of warming and cooling in the atmosphere within the past 50 years. It may be too late to halt the decline of the West Antarctic ice shelves, a study found, but climate action could still forestall the gravest sea level rise.

Due to its thickness and high elevation, researchers have regarded the East Antarctic Ice Sheet as relatively stable and more resilient against climate change than the West Antarctic Ice Sheet, which sits much closer to sea level and experiences warmer average temperatures. ![]()
