How Much of the Earth's Surface is Underlain by Permafrost?
Journal of Geophysical Research: Earth Surface, 2021More than 80% of studies reporting the area on Earth underlain by permafrost refer to the extent of the permafrost region, which accounts for around 21 million km2 (22% of the Northern Hemisphere's exposed land surface).

Investigation, Monitoring, and Simulation of Permafrost on the Qinghai‐Tibet Plateau: A Review
Permafrost and Periglacial ProcessesThe Qinghai‐Tibet Plateau (QTP) is the largest permafrost region in the world at low and middle latitudes and high elevation. Permafrost is being degraded on the QTP due to global warming, which has a significant effect on regional climate, hydrological,

Changing climate and the permafrost environment on the Qinghai–Tibet (Xizang) plateau
Permafrost and Periglacial Processes, 2020Permafrost on the Qinghai–Tibet Plateau (QTP) has undergone degradation as a result of recent climate change. This may alter the thermo‐hydrological processes and unlock soil organic carbon, and thereby affect local hydrological, ecological, and climatic

Scientific American, 2020
The article focuses on research into how great an impact thawing permafrost in arctic regions may have on climate change. It states nearly 1,450 bill ion metric tons of organic carbon is be found in the Northern Hemisphere permafrost region and mentions as permafrost thaws, frozen soil microbes reactivate and start decomposing animal and plant remains ...

Permafrost-carbon complexities
Nature Geoscience, 2013The thawing and decomposition of carbon stored in permafrost generates greenhouse gases that could further intensify global warming. Currently, most of the thawed carbon is assumed to be converted to greenhouse gases, such as carbon dioxide and methane, and carbon decomposition is thought to only occur at the site of the thaw.

Permafrost in Transition [PDF]
Climate change results in physical changes in permafrost soils: active layer thickness, temperature, soil hydrology and abrupt thaw features in ice-rich soils. Abrupt thaw features create new landforms such as ponds, lakes and erosion phenomena. In this chapter, current observations of physical changes in permafrost soils are discussed, including their
