This rainwater contains atmospheric carbon dioxide (CO2), the currency of climate change, which fixes to the water molecule (H2O) forming a molecule called carbonic acid (CH2O3).

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

Mineral weathering from thawing permafrost can release substantial CO2 Date: September 19, 2018 Source: University of Alberta Summary: The amount of carbon dioxide released from thawing permafrost ...

By locking carbon dioxide away in sediments, weathering removes it from the atmosphere over long timescales, ... dissolve in carbonic acid -- a mix of carbon dioxide in the atmosphere and rainwater.

The amount of carbon dioxide released from thawing permafrost might be greater than ... geologic time scales, carbonic acid weathering is an important control on atmospheric CO2 levels and ...

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 ...

The reason this natural carbon cycle isn’t saving us from climate change is because it is too slow to keep up with the current rate of human carbon dioxide emissions. The chemical weathering of ...

The authors focused on one specific type of weathering, caused by chemical reactions that involve carbon dioxide. Even then, this gas doesn’t weather all minerals in the same way.

Enhanced weathering in the US corn belt delivers carbon removal with agronomic benefits. Proceedings of the National Academy of Sciences , 121 (9). doi: 10.1073/pnas.2319436121 ...

But the process, known as weathering, takes tens of thousands of years. Stanford University chemists have now come up with a practical, low-cost way to sequester carbon dioxide using crushed rocks.
