Rapid Arctic environmental change affects the entire Earth system as thawing permafrost
ecosystems release greenhouse gases to the atmosphere. Understanding how much …

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 …

Tip** elements are components of the Earth system which may respond nonlinearly to
anthropogenic climate change by transitioning toward substantially different long‐term …

Background The global human footprint has fundamentally altered wildfire regimes, creating
serious consequences for human health, biodiversity, and climate. However, it remains …

Methane emissions from boreal and arctic wetlands, lakes, and rivers are expected to
increase in response to warming and associated permafrost thaw. However, the lack of …

Climate warming threatens to destabilize vast northern permafrost areas, potentially
releasing large quantities of organic carbon that could further disrupt the climate. Here we …

Subsea permafrost carbon pools below the Arctic shelf seas are a major unknown in the
global carbon cycle. We combine a numerical model of sedimentation and permafrost …

A huge amount of carbon (C) is stored in permafrost regions. Climate warming and
permafrost degradation induce gradual and abrupt carbon emissions into both the …

This study investigated the zones associated with the potential distribution and absence of
frozen ground and gas hydrates on the East Siberian Arctic Shelf in the Laptev and East …

The distribution and state of subsea permafrost is largely unknown. Present maps, which
rely heavily on model results, suggest that subsea permafrost is confined to the Beaufort …
