CAMBRIDGE, Mass., Nov. 7, 2007 — Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon ...

On the moon, the lack of atmosphere and accompanying features such as biological activity, oxygen-rich air, flowing water and ...

Geochemical weathering in mineral deposits encompasses the breakdown of primary rock‐forming minerals, the mobilisation and fixation of liberated elements, and the development of secondary mineral ...

Microbial weathering in soils encompasses the biological mechanisms by which microorganisms drive the breakdown, alteration and mobilisation of minerals. Through a suite of chemical, physical and ...

Scientists have discovered that chemical weathering, a process in which carbon dioxide breaks down rocks and then gets trapped in sediment, can happen at a much faster rate than scientists previously ...

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 ...

Natural geological processes have been regulating Earth's climate for millions of years. Accelerated versions of these processes are now being promoted as technologies to draw down carbon from the ...

Could blending of crushed rock with arable soil lower global temperatures? Researchers study global warming events from 40 and 56 million years ago to find answers. The Earth is getting hotter and ...

The natural rock weathering process, while effective in breaking down carbon and storing it within rocks over thousands of years, may not provide the immediate solution to combat climate change. With ...

Scientists have understood for years that silicate minerals react with CO 2 and water to remove CO 2 from the atmosphere, acting as a thermostat that kept Earth’s climate broadly stable over billions ...

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 ...
