Tundra vegetation productivity and composition are responding rapidly to climatic changes
in the Arctic. These changes can, in turn, mitigate or amplify permafrost thaw. In this Review …

Warming amplification over the Arctic Pole (AP hereafter) and Third Pole (Tibetan Plateau,
TP hereafter) can trigger a series of climate responses and have global consequences …

Agricultural lands, because of their large area and exhaustive management practices, have
a substantial impact on the earth's carbon and nitrogen cycles, and agricultural activities …

Under a warming climate, degrading permafrost profoundly and extensively affects arctic
and alpine ecology. However, most existing relevant studies are more focused on the …

ABSTRACT The Tibetan Plateau and its surroundings are known as the Third Pole (TP).
This region is noted for its high rates of glacier melt and the associated hydrological shifts …

The formation, growth and drainage of lakes in Arctic and boreal lowland permafrost regions
influence landscape and ecosystem processes. These lake and drained lake basin (L-DLB) …

Ice wedges are common features of the subsurface in permafrost regions. They develop by
repeated frost cracking and ice vein growth over hundreds to thousands of years. Ice-wedge …

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 …

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 …

Permafrost carbon feedback (PCF) modeling has focused on gradual thaw of near-surface
permafrost leading to enhanced carbon dioxide and methane emissions that accelerate …
