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 ...
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
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 ...
