The skyscraper-sized slab plunged into the ocean, triggering waves that rocked nearby vessels violently. Passengers screamed as cameras kept rolling. Scientists later linked increasing calving events to rising global temperatures. The viral footage transformed climate statistics into visceral reality — a frozen giant collapsing before human eyes.
