Long before humans measured temperature or mapped the poles, the slow violence of continental drift was already deciding which ends of the Earth would freeze and which would remain open to warmth. New research confirms that Antarctica's glaciation preceded the Arctic's by millions of years — a consequence of Gondwana's ancient fragmentation, which isolated the southern continent within a ring of cold ocean current and sealed its fate as the planet's first great ice archive. The finding reminds us that today's climate is not a system born yesterday, but the living inheritance of geological deci
