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

Climate change is identified as a major threat to wetlands. Altered hydrology and rising
temperature can change the biogeochemistry and function of a wetland to the degree that …

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 …

impacts and projected risks of climate change to terrestrial and freshwater ecosystems …

Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N),
but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we …

Executive summary Land and climate interact in complex ways through changes in forcing
and multiple biophysical and biogeochemical feedbacks across different spatial and …

The two most urgent and interlinked environmental challenges humanity faces are climate
change and biodiversity loss. We are entering a pivotal decade for both the international …

The carbon balance of peatlands is predicted to shift from a sink to a source this century.
However, peatland ecosystems are still omitted from the main Earth system models that are …

The northern peatland carbon sink plays a vital role in climate regulation; however, the
future of the carbon sink is uncertain, in part, due to the changing interactions of peatlands …

Water-table drawdown across peatlands increases carbon dioxide (CO2) and reduces
methane (CH4) emissions. The net climatic effect remains unclear. Based on global …
