Terradot, a carbon removal company, is using “enhanced rock weathering” to sequester carbon by spreading crushed volcanic ...

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 ...

New research reveals how the Earth might overcorrect for global warming. For a long time, scientists believed that the ...

A technique known as “enhanced rock weathering” may help remove carbon from the atmosphere, and a model shows the method will only leak minimal carbon if its products are stored in the ocean.

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

For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20° Celsius, facilitating life on our planet. To maintain such stable ...

New research shows warming events can, under certain conditions, trigger long-term cooling strong enough to resemble past ice ages.

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, ...

During the Ordovician period, the concentration of carbon dioxide in Earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the ...

The prevailing theory used to explain geographical variability in weathering is based on visual correlations with climatic regions. For instance, mechanical weathering is assumed to predominate in ...
