## TL;DR

The Arctic (North Pole region) and Antarctic (South Pole continent) are Earth's polar extremes. Arctic: ocean surrounded by continents, floating sea ice, indigenous peoples, polar bears. Antarctic: continent surrounded by ocean, ice sheet (70% of Earth's freshwater), no permanent residents, penguins. Antarctic Treaty (1959): continent dedicated to peace and science.

## Core Explanation

Arctic warming 4x faster than global average (Arctic amplification). Permafrost: frozen soil storing 1,500 Gt carbon — thaw releases CO₂/CH₄. Antarctic ice sheet: 58m sea level equivalent if fully melted. Northern Sea Route: Arctic shipping opening as ice melts. Antarctic: coldest (-89.2°C recorded, Vostok 1983), windiest, driest continent. Research stations: ~70 (summer), ~30 (winter).
