Arctic Zone

The Arctic is the northernmost region of Earth, centered on the North Pole. It is characterized by extreme cold, with distinct polar climates, unique plant and animal life, and specific geographical features. The term "Arctic" comes from the Greek word for "bear," referencing the constellation of the Bear. While the Arctic Circle (66°30′ N latitude) is a mathematical boundary, a more practical definition of the Arctic region is the area north of the tree line.1

This vast region includes Greenland, Svalbard, and the northern parts of Siberia, Alaska, and Canada. Arctic conditions feature significant temperature fluctuations between seasons, permanent snow and ice in higher elevations, and permafrost in the lowlands. Despite the harsh environment, the Arctic supports a specialized ecosystem, with marine life like beluga whales, narwhals, seals, and polar bears, and land animals such as caribou and musk oxen. The region is also crucial for studying global meteorology and is increasingly recognized as a bellwether for global climate change, warming at a rate significantly faster than the rest of the world.12345
