Abstract

• 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
