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 ...

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, ...

Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface. The results call into ...

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, ...

Not all nitrogen comes from the atmosphere Up to a quarter of nitrogen on Earth comes from rocks Discovery could greatly improve climate change projections and focus carbon sequestration efforts For ...

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 ...

Hebrew University experts continue in footsteps of researcher who built special reactor that flushes CO2, seawater through ...

It rains a lot here in the wettest place on earth. Months and months of steady, unrelenting rain, falling on our rooftops, falling on our hills. I’ve imagined it as many things – a singer of lullabies ...

A new University of Washington study shows that the textbook understanding of global chemical weathering -- in which rocks are dissolved, washed down rivers and eventually end up on the ocean floor to ...
