Weathering modifies rock fabric through chemical alteration and physical disintegration, driving changes in pore structure, fracture density and mineral assemblage. Chemical reactions between water, ...

A tractor spreads crushed white rock on a green hill, leaving a plume of dust in its wake. Scientists believe that enhanced rock weathering may offer a way to remove carbon from the atmosphere if it ...

Since the early 1980s, Earth scientists have understood that erosion and weathering of rock slowly removes CO 2 from the atmosphere, regulating Earth’s climate on geological timescales. But recent ...

It almost seems too simple to be true. Silicate rock, during the natural process of breaking down in soil, draws carbon from the air – thus helping to absorb carbon emissions and potentially ...

A new study published in the journal Nature reveals that the thawing of permafrost soils does not only release carbon, but may also promote its removal from the atmosphere. Climate warming contributes ...

Gray, rough-looking olivine rocks surrounded by greenish sand. Olivine makes up over half of the Earth's upper mantle. On beaches like the one seen here, the mineral dissolves in seawater, increasing ...

Most countries will not achieve climate neutrality through greenhouse gas emission reductions alone; carbon sinks are also needed to offset unavoidable emissions. Researchers are discussing technical ...

The uplift-weathering hypothesis suggests that tectonic uplift increases erosion, exposes fresh silicate minerals, and accelerates reactions that consume atmospheric CO 2. This process has often been ...

Rock weathering, the breakdown and dissolving of rocks and minerals caused by their exposure to water, air and biological life, is a major regulator of Earth's atmospheric CO 2 levels and climate.
