A new study shows how land and ocean weathering form one system, linking rivers, rocks, and seafloor muds to shape Earth’s ...

The alkaline material in the rocks then reacts with dissolved CO₂ in rainwater to form stable carbonate minerals, such as calcite or dolomite, which do not easily break down. These carbonates filter ...

It creates a positive feedback loop: the recycled nutrients fuel even more plankton growth, which removes more oxygen, leading to more nutrient recycling. The overall effect is the plankton’s ...

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 ...

New research shows that today’s global warming could eventually overshoot into runaway cooling, setting the stage for a ...

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 ...

What processes have regulated climate over the course of Earth’s history? Researchers are addressing this question in the ...

From a distance, Biosphere 2 emerges from the cacti and creosote of the Sonoran desert like a gleaming oasis, a colony of ...

A group of researchers has taken advantage of different erosion rates and investigated how uplift and erosion of rocks determine the balance of carbon emissions and uptake. The surprising result: at ...

The geology and surface processes of Venus continue to intrigue planetary scientists, revealing a dynamic world shaped by volcanic activity, tectonic forces and chemical weathering. Recent ...

New research has overturned the traditional view that natural rock weathering acts as a carbon sink that removes CO2 from the atmosphere. Instead, this can also act as a large CO2 source, rivaling ...
