With wildfires and increased warming, scientists say the Arctic’s tundra is now a carbon source. The region had been a carbon sink for thousands of years (NOAA Climate.gov; Arctic Report)
According to the US Energy Information Administration, the arctic tundra holds an estimated 13% or 90 billion barrels of the world's undiscovered conventional oil sources. However, there are a number of challenges to oil exploration, drilling, and transportation in an arctic tundra environment that limits the profitability of the venture. [15]

A tundra climate is characterized by having at least one month whose average temperature is above 0 °C (32 °F), while an ice cap climate has no months averaging above 0 °C (32 °F). [2] In a tundra climate, even coniferous trees cannot grow, but other specialized plants such as the arctic poppy can grow. In an ice cap climate, no plants can ...
The Kalaallit Nunaat high arctic tundra ecoregion covers the coastal areas of northern including the upper half of the west coast and the upper one-third of the east coast. [1] Greenland (called Kalaallit Nunaat in the Greenlandic language). Areas inland of this strip of land are either covered in ice or bare rock.
From giant holes in Siberia to legions of beavers in Alaska, the Arctic is changing rapidly and accelerating the climate crisis across the planet.
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest ) and tundra . [ 2 ]
A focus of the latest Arctic evaluation was the effects of warmer weather and wildfires on the tundra, a far-northern biome that's typically known for extreme cold, little precipitation and a ...
