GreenTracker| A new study on melting glaciers indicates the ice-loss acceleration began moving up the northwest coast of Greenland starting in late 2005. This trend has not been well-documented until now.
The team drew their conclusions by comparing data from NASA’s Gravity and Recovery Climate Experiment satellite system, or GRACE, with continuous GPS measurements made from long-term sites on bedrock on the edges of the ice sheet.
“When we look at the monthly values from GRACE, the ice mass loss has been very dramatic along the northwest coast of Greenland,” said CU-Boulder physics Professor and study co-author John Wahr, also a fellow at CU-Boulder’s Cooperative Institute for Research in Environmental Sciences.
“This is a phenomenon that was undocumented before this study,” said Wahr. “Our speculation is that some of the big glaciers in this region are sliding downhill faster and dumping more ice in the ocean.” via Science Daily
