Human Activity Drives Arctic Carbon Crisis Through Climate Change
“Cause of the Arctic carbon crisis is human driven climate change such as fossil fuel emissions that have warmed the Arctic and have been pushing the region past the natural temperature range it is maintained for many years. Altering structure and function of national systems the permafrost that once stayed frozen year round now thaws deeper and furlong periods of time Shifts in groundwater move differently through thawed soil Rivers carrying more sediment nutrients and dissolved organic carbon To understand Arctic thaw we recognize humans have altered the climate system which then alters natural systems that used to be stable for thousands of years and fossil fuel emissions have warmed the Arctic much faster than the global average. To help the issue you have to understand that humans trigger the thaw and means solutions must focus on reducing greenhouse gas emissions slow in warming and protecting the systems that are still stable and monitoring permafrost”
Summary
Human‑driven fossil‑fuel emissions are warming the Arctic at about twice the global average, forcing permafrost beyond its historic temperature range. The resulting thaw deepens permafrost, changes groundwater flow, and increases river transport of sediment, nutrients and dissolved organic carbon, releasing large greenhouse‑gas quantities that amplify warming. Mitigation therefore requires cutting emissions and monitoring permafrost.

Residents of the children's hometown of Niugtaq, Alaska, were relocated further inland because of climate change–induced flooding and land loss. Such immediate needs can distract from the urgency of potential exposures to contaminants, says Langer. Both images © Andrew Burton/Getty Images. Unfortunately, the double-barreled threat to Arctic peoples of thawing permafrost and exposed contaminants does not exist in isolation.29 Traditional foods30 and the availability and quality of drinking water31 in these far-northern communities are threatened.

- The thaw beneath our feet | Nature Reviews Earth & Environment
Permafrost — ground that remains ≤0 °C for at least two consecutive years — is thawing. The resulting impacts are vast and potentially rapid, influencing both human and natural systems. For instance, 10s to 100s Pg of carbon could be released by the end of this century (with even greater losses after 2100), driving the permafrost carbon feedback that contributes further warming. Moreover, one third of Arctic infrastructure faces high risk thaw-related structural damage by mid-century, and high-latitude coastal infrastructure is threatened by rapidly increasing erosion.

- Climate-carbon feedback tradeoff between Arctic and alpine permafrost under warming | Science Advances
Current GHG mitigation options, including carbon pricing, renewable energy incentives, and energy efficiency standards, have not adequately accounted for feedback of CH4 emissions from permafrost regions under climate warming due to scarcity of in situ observations and geospatial datasets (22). Limited experiments show that warming stimulates CH4 release in Arctic wetland permafrost but enhances CH4 uptake in nonwetland permafrost depending on local landscapes and combined response of methanotrophs and methanogens (23, 24).

“It does not mean that in the real world humans are less responsible for the changes. It means that climate models have different physics compared to real-life physics,” he says.
