enhanced weathering

UC Davis researchers find adding crushed volcanic rock to farmlands can remove carbon dioxide from the air. This 'enhanced' rock weathering works even in dry climates. (Amy Quinton/UC Davis)

Adding crushed volcanic rock to cropland could play a key role in removing carbon from the air

Could blending of crushed rock with arable soil lower global temperatures?

The glacial rock flour can be found in Iluilak in Nuuk Fjord. Here the deposit is raised, so you easily can see the grey glacial rock flour. Foto: Minik Rosing.

Could Greenlandic glacial rock flour really help to stop climate change?
