Are new carbon sinks appearing in the Arctic?

In 2018, an international research group bored for soil samples in three sites around the Isfjorden fjord in Svalbard, which is part of Norway. The same phenomenon was seen at each boring site: mineral soil covered by a thin ...

Tropical peatland, sea level rise and climate change

Tropical peatlands are among the most efficient carbon sinks. The flip side is that they can become massive emitters of carbon if they are damaged, for instance, by land use change, degradation or fire. This can lead to faster ...

Peatlands clean up acid mine drainage

The pollution of groundwater and surface waters with sulfate and iron from acid mine drainage is a worldwide problem in post-mining landscapes. Researchers from the Humboldt University of Berlin (HU-Berlin) and the Leibniz ...

Peat

Peat (turf) is an accumulation of partially decayed vegetation matter or histosol. Peat forms in wetland bogs, moors, muskegs, pocosins, mires, and peat swamp forests. Peat is harvested as an important source of fuel in certain parts of the world. By volume, there are about 4 trillion m³ of peat in the world covering a total of around 2% of global land area (about 3 million km²), containing about 8 billion terajoules of energy.

Losing 5% of the 2.7m hectares of peatland in Britain, would equal UK's annual carbon emissions and risk its climate targets (IUCN). The UK is amongst the top ten nations of the world in the peatland area and has 9-15% of Europe’s peatland area.
