Soil organic matter (SOM) anchors global terrestrial productivity and food and fiber supply.
SOM retains water and soil nutrients and stores more global carbon than do plants and the …

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 …

In boreal forests, climate warming is shifting the wildfire disturbance regime to more frequent
fires that burn more deeply into organic soils, releasing sequestered carbon to the …

Thermokarst is the process whereby the thawing of ice-rich permafrost ground causes land
subsidence, resulting in development of distinctive landforms. Accelerated thermokarst due …

This chapter addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4),
and nitrous oxide (N2O). The three greenhouse gases have increased in the atmosphere …

Soils play a key role in providing a range of ecosystem services. Quality-assessed soil
information, with quantified uncertainty levels, is needed to address a range of global issues …

Changing climate in northern regions is causing permafrost to thaw with major implications
for the global mercury (Hg) cycle. We estimated Hg in permafrost regions based on in situ …

Soils and other unconsolidated deposits in the northern circumpolar permafrost region store
large amounts of soil organic carbon (SOC). This SOC is potentially vulnerable to …

Soil organic carbon (SOC) stored in permafrost across the high-latitude/altitude Northern
Hemisphere represents an important potential carbon source under future warming. Here …

Climate change will impact every aspect of biophysical systems and society. However,
unlike other components of the climate system, the impact of climate change on the …
