The Alps are steadily “growing” by about one to two millimeters per year. Likewise, the formerly glaciated subcontinents of North America and Scandinavia are also undergoing constant upward movement. This is due to the fact that at the end of the Last Glacial Maximum (LGM) about 18,000 years ago the glaciers melted and with this the former heavy pressure on the Earth’s surface diminished. The ice reacted rapidly to climate change at that time whereas the Earth’s crust is still responding today to this relatively sudden melting of ice.
