Antarctica’s 9,000-Year Ice Collapse: Lessons for Today’s Ocean-Driven Melt
New insights into an ancient trigger: warmer oceans and rapid ice loss Scientists have pieced together evidence that about 9,000 years ago, a portion of East Antarctica’s ice sheet collapsed unusually quickly. The event, driven by warmer ocean waters intruding under the ice, offers a window into how today’s oceans might influence the stability of…

Lessons from the Past: What Antarctica’s 9,000-Year Collapse Tells Us About Today’s Climate
Understanding an Ancient Collapse About 9,000 years ago, parts of Antarctica’s eastern ice sheet collapsed in a remarkably rapid event, driven by warmer ocean waters penetrating the ice shelves. This ancient episode occurred under climate conditions that paleoclimatologists now compare to certain patterns seen today: rising ocean temperatures, changing wind patterns, and a shift in…
