Knowledge of soils in the permafrost region has advanced immensely in recent decades,
despite the remoteness and inaccessibility of most of the region and the sampling limitations …

Mangrove forests store and sequester large area-specific quantities of blue carbon (Corg).
Except for tundra and peatlands, mangroves store more Corg per unit area than any other …

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 …

Thawing permafrost and the resulting microbial decomposition of previously frozen organic
carbon (C) is one of the most significant potential feedbacks from terrestrial ecosystems to …

A major challenge in predicting Earth's future climate state is to understand feedbacks that
alter greenhouse-gas forcing. Here we synthesize field data from arctic Alaska, showing that …

Moist calcareous tundra has many ecosystem properties analogous to those of the
hypothesized “Mammoth Steppe” or steppe tundra of glacial Beringia, and today it is an …

Global warming is predicted to be most pronounced at high latitudes, and observational
evidence over the past 25 years suggests that this warming is already under way. One-third …

In arctic Alaska, air temperatures have warmed 0.5 degrees Celsius (° C) per decade for the
past 30 years, with most of the warming coming in winter. Over the same period, shrub …

While a new class of Dynamic Global Ecosystem Models (DGEMs) has emerged in the past
few years as an important tool for describing global biogeochemical cycles and atmosphere …

Soils are the major component of the terrestrial ecosystem and the largest organic carbon
reservoir on Earth. However, they are a nonrenewable natural resource and especially …
