The Critical Zone encompasses the near‐surface environment where rock, soil, water, air and biota interact in a dynamic equilibrium that drives essential geochemical cycles. Research in this area ...

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 ...

Scientists have come up with a model to better understand how weathering, the process that acts as Earth's thermostat, responds to changing global temperatures. Rocks, rain and carbon dioxide help ...

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 ...

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 ...

Exposed rocks along the coastline can be broken down by the processes of weathering. Freeze-thaw weathering occurs when rocks are porous (contain holes) or permeable (allow water to pass through).

On a banana plantation in rural Australia, a second-generation farming family spreads crushed volcanic rock between rows of ripening fruit. Eight thousand kilometers away, two young men in central ...
