Melting glaciers in Greenland are unleashing hidden methane and shifting soils from carbon sinks to warming sources.

Mineral weathering occurs when minerals previously locked-up in permafrost are exposed, and broken down into their chemical components by the sulfuric or carbonic acid that can exist naturally in ...

In mined landscapes with abundant sulfuric acid, the weathering reactions no longer rely on carbonic acid, and the potential for geologic carbon sequestration is eliminated.

Their results reveal that sulfuric-acid driven weathering has intensified with regional permafrost thaw in recent decades, and likely increased CO2 release into surrounding water and air.

What is ERW? ERW aims to turbocharge a natural geological process called weathering. Weathering is the breakdown of rocks by carbonic acid, which forms when CO2 in the air or soil dissolves into ...

However, under certain conditions, weathering by sulfuric acid can release quite a lot of carbon dioxide – and researchers from the Department of Biological Sciences have shown that these ...

Kane Cave in northern Wyoming was also formed from sulfuric acid weathering. Sulfuric acid is capable of dissolving vast amounts of limestone minerals — far more than carbonic acid can — but ...

Emergency works costing £40,000 will be completed at a trio of medieval church sites affected by ageing and weathering.

In short: Rainwater combined with the atmospheric carbon dioxide, resulting in carbonic acid that caused enhanced weathering of rock, thus releasing calcium and magnesium.

As UNESCO's decision draws close on what happens with Murujuga's World Heritage nomination, a scientific paper has been ...

Moreover, unlike carbonic-acid-driven weathering, the increased delivery of phosphate from sulphuric acid weathering of apatite would be unaccompanied by increased alkalinity.
