Long before human memory or recorded history, the shape of the Earth itself determined where ice could take hold. New research confirms that Antarctica's ice sheet formed roughly twenty million years before the Arctic's, a disparity traced back to the breakup of the supercontinent Gondwana more than one hundred million years ago. As Antarctica drifted into isolation, the Southern Ocean formed around it like a cold moat, cutting the continent off from warmer waters and allowing glaciation to begin during the Eocene epoch — while the Arctic, still cradled by connected landmasses, would not freez

Lente Económico
📈
Antarctica's ice sheet formed 100+ million years ago due to Gondwana's continental breakup, predating Arctic glaciation by millions of years. This paleoclimate discovery has minimal direct economic impact.

No immediate consumer impact. Long-term, improved understanding of ice sheet formation may refine climate models used for infrastructure planning, insurance pricing, and coastal property valuations in vulnerable regions.
May inform climate change modeling and long-term environmental policy. Could influence funding priorities for polar research and climate adaptation strategies, particularly for coastal communities facing sea-level rise risks.
