The Arctic tundra, predominantly located in the Northern Hemisphere across regions such as Russia, Alaska, Canada, Greenland, and Scandinavia, is a unique ecosystem characterized by extreme temperatures and limited vegetation. In this harsh climate, vegetation struggles to grow when ice caps prevent melting. The tundra experiences two distinct seasons: a brief summer with nearly 24 hours of sunlight, where temperatures hover between 3°C and 12°C, and a frigid winter with weeks of darkness, where temperatures can plummet to -70°C. Understanding this ecosystem is vital for wildlife and climate studies.
