Warm Water Accelerates Melting of the 'Doomsday Glacier' Introduction: A recent study reveals that warm and high-pressure seawater is melting the Thwaites Glacier in West Antarctica, often referred to as the 'Doomsday Glacier,' at an alarming rate. This process could lead to significant revisions in global sea-level rise predictions. The Impact of Warm Seawater: Researchers from the University of California, Irvine, utilized high-resolution satellite radar data to uncover the extent of seawater intrusion beneath the glacier.  This interaction between ocean water and the glacier's base is causing rapid melting, a phenomenon likely occurring throughout Antarctica and Greenland, necessitating a reevaluation of sea level projections. Insights from ICEYE Satellite Mission: To understand how ocean water affects glacial melting, data from Finland's ICEYE satellite mission was analyzed.  These satellites use interferometric synthetic aperture radar (InSAR) to mo...
