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 ...

During the Ordovician period, the concentration of CO2 in the earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the Ordovician ...

A new study published in the journal Nature has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large carbon dioxide source, ...

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, ...

Rocks are not eternal. Even the tallest mountain will eventually dissolve and disintegrate. Geologists call this process “weathering.” It sounds harmless enough, but weathering is one of the most ...

Reactions between rocks, rain and carbon dioxide in the atmosphere have helped to stabilise the climate throughout Earth’s history, but they won’t prevent our carbon emissions from causing severe ...

In the whole history of Earth’s climate, few events are as extreme as those that geologists call “Snowball Earth.” But scientists still wonder why these events happen in the first place and what ...
