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 ...
A severe threat to tundra is global warming, which causes permafrost to thaw. The thawing of the permafrost in a given area on human time scales (decades or centuries) could radically change which species can survive there. [ 13 ]
When including the impact of increased wildfire activity, the Arctic tundra region has shifted from storing carbon in the soil to becoming a carbon dioxide source. / Credit: NOAA
An observed impact of climate change is a strong increase in the number of lightnings in the Arctic. Lightnings increase the risk for wildfires. [45] Some research suggests that globally, a warming greater than 1.5 °C (2.7 °F) over the preindustrial level could change the type of precipitation in the Arctic from snow to rain in summer and autumn.
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).
