"NASA Reveals Alarming Sinking of Major US East Coast Cities"

NASA images show that the land on which major U.S. cities like New York and Baltimore are built is sinking, exacerbating the threat of rising sea levels. The land subsidence, occurring at a rate of 1 to 2 millimeters per year, poses a significant risk to infrastructure, farmland, and wetlands along the East Coast. The problem is particularly acute in cities like Charleston, where downtown is just 10 feet above sea level and experiences subsidence of about 4 millimeters per year. The issue, caused by a combination of natural and human factors, could lead to increased damage to homes, saltwater intrusion, and other challenges for coastal communities.
