Permafrost and climate change: Carbon cycle feedbacks from the warming Arctic
Rapid Arctic environmental change affects the entire Earth system as thawing permafrost
ecosystems release greenhouse gases to the atmosphere. Understanding how much …

Arctic tundra shrubification: a review of mechanisms and impacts on ecosystem carbon balance
Vegetation composition shifts, and in particular, shrub expansion across the Arctic tundra
are some of the most important and widely observed responses of high-latitude ecosystems …

Five years of whole-soil warming led to loss of subsoil carbon stocks and increased CO2 efflux
Subsoils below 20 cm are an important reservoir in the global carbon cycle, but little is
known about their vulnerability under climate change. We measured a statistically significant …

Environmental drivers of increased ecosystem respiration in a warming tundra
Arctic and alpine tundra ecosystems are large reservoirs of organic carbon,. Climate
warming may stimulate ecosystem respiration and release carbon into the atmosphere,. The …

Climate change and the permafrost carbon feedback
Large quantities of organic carbon are stored in frozen soils (permafrost) within Arctic and
sub-Arctic regions. A warming climate can induce environmental changes that accelerate …

Nitrogen availability mediates soil carbon cycling response to climate warming: A meta‐analysis
Global climate warming may induce a positive feedback through increasing soil carbon (C)
release to the atmosphere. Although warming can affect both C input to and output from soil …

Direct observation of permafrost degradation and rapid soil carbon loss in tundra
Abstract Evidence suggests that 5–15% of the vast pool of soil carbon stored in northern
permafrost ecosystems could be emitted as greenhouse gases by 2100 under the current …

Responses of terrestrial ecosystems to temperature and precipitation change: A meta‐analysis of experimental manipulation
Global mean temperature is predicted to increase by 2–7° C and precipitation to change
across the globe by the end of this century. To quantify climate effects on ecosystem …

Lakes and reservoirs as regulators of carbon cycling and climate
We explore the role of lakes in carbon cycling and global climate, examine the mechanisms
influencing carbon pools and transformations in lakes, and discuss how the metabolism of …
