Not all nitrogen comes from the atmosphere Up to a quarter of nitrogen on Earth comes from rocks Discovery could greatly improve climate change projections and focus carbon sequestration efforts For ...

Weathering of huge amounts of tiny rocks could be a means to reduce the greenhouse gases in the atmosphere. While this is normally a slow natural process during which minerals chemically bind CO2, ...

High erosion in southern France exposes these sedimentary rocks to weathering, releasing carbon dioxide as the ancient organic carbon breaks down. The Earth’s stones contain a large amount of carbon ...

Sedimentary rocks on the banks of the Mackenzie River, Canada, a major river basin where rock weathering is a CO2 source. Image credit: Robert Hilton. Rocks contain an enormous store of carbon in the ...

Reactions between rocks, rain and carbon dioxide in the atmosphere have helped to stabilise the climate throughout Earth’s history, but they won’t prevent our carbon emissions from causing severe ...

Not all of the nitrogen on the planet comes from the atmosphere, according to a new study. Up to a quarter comes from Earth's bedrock. The discovery could greatly improve climate change projections.
