Globally, peatland ecosystems store approximately 25%  of the world's soil organic carbon  and 10% of the world's freshwater resources , despite only occupying 3% of the global land area . The long-term role of northern peatlands in the carbon cycle was mentioned for the first time in IPCC AR4 , while SR1.5 briefly mentioned the combined effects of changes in climate and land use on peatlands . New evidence confirms that climate change, including extreme weather events , permafrost degradation , SLR  and fire  , superimposed on anthropogenic disturbances , has led to rapid losses of peatland carbon across the world  . Other essential peatland ecosystem services, such as water storage and biodiversity, are also being lost worldwide  .
