Arctic permafrost, the largest non-seasonal component of Earth's cryosphere, contains a
substantial climate-sensitive carbon pool. The existence of a global tipping point, a warming …

Our knowledge on permafrost carbon (C) cycle is crucial for understanding its feedback to
climate warming and developing nature-based solutions for mitigating climate change. To …

The largest stocks of soil organic carbon can be found in cold regions such as Arctic,
subarctic and alpine biomes, which are warming faster than the global average …

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

Wildfires over permafrost put perennially frozen carbon at risk. However, wildfire emissions
from biomass burning over the diverse range of permafrost regions and their share in global …

As the largest and highest plateau in the world, ecosystems on the Tibetan Plateau (TP)
imply fundamental ecological significance to the globe. Among the variety, alpine grassland …

Permafrost wetlands are closely related to potential greenhouse gas emissions under
climate warming. In recent decades, climate change and human activities have induced …

Anthropogenic climate change has driven an increase in the frequency, size, and severity of
fires at high latitudes. Recent research shows that increasing fire severity in the subarctic is …

We present a detailed soil organic carbon (SOC) and phytomass carbon (C) inventory for a
mountain periglacial region in northwest Sweden (altitude range c. 600–1,800 m). We …

Increased warming in the Arctic is of great concern. This is particularly due to permafrost
degradation, which is expected to accelerate microbial breakdown of soil organic carbon …
