Permafrost is a geological product of climate and microclimate, and therefore its properties and distribution change as climate and land surface features change, though with a response that is delayed with depth and time. Direct observations of permafrost temperature and active-layer thickness in ...

Permafrost and climate change 来自 dx.doi.org 喜欢 0 阅读量: 80 作者: JB Murton 摘要: Permafrost is ground that remains at or below 0°C for at least two consecutive years. It varies in thickness from centimeters to ~1500 m and presently underlies ~16–21 × 10 km of Earth's land ...
“The loss of permafrost usually means the loss of terra firma in an otherwise often boggy landscape,” Turetsky said. “Roads, buildings and whole communities will have to cope with this aspect of climate change. What this means for ecosystems and humans residing in the North remains of the ...

A large amount of organic carbon stored in frozen Arctic soils (permafrost) could be released as carbon dioxide and methane in a warming climate, which would accelerate the pace of climate change; this review suggests that release of greenhouse gas emiss
fertilization and climate change changes from a sink of 68 Pg to a 27+‐7 Pg sink to 4+‐18 Pg source, depending on the processes and parameter values used. The integrated change in carbon due to climate change shifts from near zero, which is within the range of previous model esti...

Andrew MacDougall and colleagues, at the University of Victoria, British Columbia, Canada, used a coupled global climate model to investigate the possible temperature increase associated with the permafrost carbon release. They investigated different warming scenarios associated with anthropogenic emissions ...
