Peatland fires reduce future methane production in peat soils

Climatic changes are increasingly giving rise to major fires on peatlands in the northern hemisphere, which release massive quantities of carbon dioxide. However, the biomass of the peatland is not entirely consumed by fire, ...

Historical climate effects of permafrost peatland surprise researchers

Peatlands are an important ecosystem that contribute to the regulation of the atmospheric carbon cycle. A multidisciplinary group of researchers, led by the University of Helsinki, investigated the climate response of a permafrost ...

Global peatland dry-out could release 860 million tons of carbon dioxide per year

Peatlands, such as fens, bogs, marshes and swamps, cover just 3% of the Earth's total land surface, yet store over one-third of the planet's soil carbon. That's more than the carbon stored in all other vegetation combined, ...

Complex ecosystem changes cause more greenhouse gases to be emitted from peatlands

Peatlands, which make up 3 percent of Earth's total land area, are known by a number of names—moors, mires, bogs, swamps and portions of permafrost tundra. They also store a significant amount of the Earth's carbon.

Substantial carbon dioxide emissions from northern peatlands drained for crop cultivation

A new study shows that substantial amounts of carbon dioxide were released during the last millennium because of crop cultivation on peatlands in the Northern Hemisphere.

Scientists establish new records of Singapore's sea-level history

Climate scientists at the Nanyang Technological University, Singapore (NTU, Singapore) have extended the known record of Singapore's sea level to almost 10,000 years ago, providing a more robust dataset to aid future predictions ...

Underwater ancient cypress forest offers clues to the past

When saber-toothed tigers, woolly mammoths and giant sloths roamed North America during the last Ice Age about 18,000 to 80,000 years ago, the Gulf Coast's climate was only slightly cooler, more similar to regions to the ...

How much carbon will peatlands lose as permafrost thaws?

Just as your freezer keeps food from going bad, Arctic permafrost protects frozen organic material from decay. As the climate warms, however, previously frozen landscapes such as peatlands are beginning to thaw. But how much ...

Restored peatlands store carbon and mitigate climate change

Estonia has almost 10,000 ha of peat production land that has lain abandoned since the Soviet era, as well as peatland that is in use at present for peat production but whose resources will be exhausted in the near future. ...

Better peatland management could cut half a billion tons of carbon

Half a billion tonnes of carbon emissions could be cut from Earth's atmosphere by improved management of peatlands, according to research partly undertaken at the University of Leicester.
