As Scandinavian peninsula rises from sea, new satellite data show gravity changes

The article from MSN discusses how the Scandinavian Peninsula is undergoing significant geological changes due to post-glacial rebound, a process where land rises after being relieved of the weight of ice from the last glacial period. Recent satellite data from the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On missions have revealed that this uplift is causing measurable changes in Earth's gravity field. The data indicates that the uplift rate in parts of Scandinavia is up to 10 millimeters per year, which not only affects the land but also influences sea levels and the gravitational pull in the region. This phenomenon is part of a broader isostatic adjustment where the Earth's crust rebounds after the melting of ice sheets, leading to a redistribution of mass and thus altering local gravity. The study of these changes provides insights into past ice sheet dynamics and current climate change impacts.
