Removal of atmospheric CO2 by rock weathering
holds promise for mitigating climate change
Large-scale removal of carbon dioxide from the
atmosphere might be achieved through enhanced
rock weathering. It now seems that this approach
is as promising as other strategies, in terms of cost
and CO2-removal potential. Johannes Lehmann
and Angela Possinger, Nature News, July 8, 2020

Pulling carbon from the sky is necessary but not
sufficient. Carbon dioxide removal is becoming a
serious proposition. But it is not a substitute for
aggressive action to cut emissions. Nature Editorial
