Tundra - Arctic, Permafrost, Climate: Tundra climates vary considerably. The most severe occur in the Arctic regions, where temperatures fluctuate from 4 °C (about 40 °F) in midsummer to –32 °C (–25 °F) during the winter months. Alpine tundra has a
Arctic, northernmost region of Earth, centered on the North Pole and characterized by distinctively polar conditions of climate, plant and animal life, and other physical features. The term is derived from the Greek word arktos (‘bear’), referring to t

Excluding Russian stations lowers representativeness markedly, with some biases being of the same magnitude as the expected shifts caused by climate change by the end of the ...
As the frozen ground warms much faster than expected, it’s reshaping the landscape—and releasing carbon gases that fuel global warming.
Tundra - Climate Change, Human Impact, Arctic: Earth’s tundra regions are harsh and remote, so fewer humans have settled there than in other environments. However, humans have a long history in the tundra. For example, the first people who went to North
