Earth's sediment cycle during the Anthropocene
The global sediment cycle is a fundamental feature of the Earth system, balancing
competing factors such as orogeny, physical–chemical erosion and human action. In this …

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 …

Exceeding 1.5 C global warming could trigger multiple climate tip** points
Climate tip** points occur when change in a part of the climate system becomes self-
perpetuating beyond a warming threshold, leading to substantial Earth system impacts …

Intergovernmental Panel on Climate Change (IPCC). Global carbon and other biogeochemical cycles and feedbacks
It is unequivocal that the increases in atmospheric carbon dioxide (CO2), methane (CH4)
and nitrous oxide (N2O) since the pre-industrial period are caused by human activities. The …

Permafrost carbon emissions in a changing Arctic
Arctic permafrost stores nearly 1,700 billion metric tons of frozen and thawing carbon.
Anthropogenic warming threatens to release an unknown quantity of this carbon to the …

Tundra vegetation change and impacts on permafrost
Tundra vegetation productivity and composition are responding rapidly to climatic changes
in the Arctic. These changes can, in turn, mitigate or amplify permafrost thaw. In this Review …

Polar regions
This chapter assesses the state of physical, biological and social knowledge concerning the
Arctic and Antarctic ocean and cryosphere, how they are affected by climate change, and …

Carbon release through abrupt permafrost thaw
The permafrost zone is expected to be a substantial carbon source to the atmosphere, yet
large-scale models currently only simulate gradual changes in seasonally thawed soil …

The status and stability of permafrost carbon on the Tibetan Plateau
Permafrost regions at high latitudes and altitudes store about half of the Earth's soil organic
carbon (SOC). These areas are also some of the most intensely affected by anthropogenic …
