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 …

Chapter 2, building on prior assessments1, provides a global assessment of the observed
impacts and projected risks of climate change to terrestrial and freshwater ecosystems …

Climate change has been partially mitigated by an increasing net land carbon sink in the
terrestrial biosphere; understanding the processes that drive this sink is thus essential for …

Chapter 2, building on prior assessments, provides a global assessment of the observed
impacts and projected risks of climate change to terrestrial and freshwater ecosystems …

Intensifying wildfire activity and climate change can drive rapid forest compositional shifts. In
boreal North America, black spruce shapes forest flammability and depends on fire for …

One paradigm in biogeochemistry is that frequent disturbance tends to deplete carbon (C) in
soil organic matter (SOM) by reducing biomass inputs and promoting losses. However …

There has been more than 75% rise in the number of extreme weather events such as
drought and flood during 2000–2019 compared to 1980–1999 due to the adverse effects of …

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

Biochars provide several agricultural and environmental benefits, such as soil health
improvement, better crop growth and yield, carbon sequestration, decreasing greenhouse …
