Human-induced climate change is devastating the tundra because intense complications are present in remote areas, free from human interference. Changes in climate, permafrost, ice pack and glacier formations pose a serious threat to the stability of global climate because these conditions are influenced and reinforced by positive feedback loops.
The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...

However, when the human factor is introduced, they have a much less successful survival rate. Aqueducts and other water projects started crisscrossing the giant kangaroo rat habitat. Agriculture moved in because of the new water routes and suddenly the habitat of many species became agricultural land. [ 17 ]
The Arctic tundra has historically helped reduce global emissions. But rising temperatures and wildfires in the region are changing that, scientists say. Arctic tundra becoming a source of carbon ...
The tundra has become a source of emissions, rather than a carbon sink, the authors said. The Arctic is heating up far faster than places at lower altitudes as melting ice reflects less radiation ...
The 2007 IPCC Fourth Assessment Report concluded that over the last three decades human-induced warming had likely had an influence on many biological systems. [25] [26] [27] The Sixth Assessment Report found that half of all species with long-term data had shifted their ranges poleward (or upward for mountain species).
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]
