Abstract. Enhanced Weathering using basalt rock dust is a scalable carbon dioxide removal (CDR) technique, but quantifying rock weathering and CDR rates poses a critical challenge. Here, we investigat...

Ocean alkalinity enhancement (OAE) is an emerging carbon dioxide CO2 removal approach for climate change mitigation and can be implemented with various alkaline materials that convert dissolved CO2 i...

Enhanced weathering involves spreading crushed silicates on soils. Upon weathering of the applied silicates, CO2 is captured via two pathways: pedogenic carbonate formation and leaching of bicarbonat....

NOAA's Ocean Acidification Program prepares us for the impacts of ocean acidification through research and interdisciplinary partnerships.

A Major Milestone: 1,000 Tonnes of Carbon Removed – With More To Come Dartmouth, Nova Scotia — Planetary has successfully removed 1,000 net tonnes of CO2 directly from the atmosphere through its ocean...

Reactions of Mg-rich silicates with calcium carbonates/sulfates result in the formation of materials that could potentially be used for low-cost carbon dioxide removal from the atmosphere.

Enhanced weathering captures CO2 via two pathways: Carbonate formation and leaching of weathering products. Here, we look beyond those two pathways, identifying other CO2 sinks and sources. While proc...
