Weathering modifies rock fabric through chemical alteration and physical disintegration, driving changes in pore structure, fracture density and mineral assemblage. Chemical reactions between water, ...

Thermal stress weathering arises when rock masses undergo temperature fluctuations that induce internal stresses through differential heating and cooling. Over short (diurnal) and long (seasonal to ...

ITHACA, N.Y. – Cornell University researchers have found that enhanced rock weathering, an emerging carbon-removal technique, needs to be widely adopted to move the needle on global warming and ...

Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of ...

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 ...

A tractor drives across a grassy field, facing the camera, between rows of wire trellises over plants pruned close to the ground. Clouds of finely ground rock spray out on either side. As part of the ...

A weird technology has emerged as a leader in the quest for net zero. But this form of carbon capture, called Enhanced Rock Weathering (or ERW for short), still requires innovation — and government ...
