New research argues that Antarctica’s first ice sheet had a geological head start. Deep geological factors, the study says, helped early ice form on the continent.
Understanding how Antarctic ice began informs models of long-term climate and ice-sheet stability. A geological advantage would mean Earth’s substrate and topography mattered alongside atmospheric cooling.
The SciTechDaily-linked summary emphasizes deep geology as an aiding factor for early ice. It does not specify the age of the first sheet or the exact geological mechanism in the one-line note.
