- Atmospheric carbon dioxide (CO2) levels are increasing by 2.37 ppm year, and levels have increased from about 370 ppm in 2000 to about 420 ppm in 20231
- Increased CO2 levels result in climate change, including increased temperatures and drought which impacts soybean crops
- Enhanced Rock Weathering (ERW) is the process of spreading basalt on fields to accelerate the natural reaction between rocks, CO2, and water2
- Enhanced Rock Weathering is a possible way to combat increasing CO2 levels because of its carbon sequestration properties2
