Soil Carbon Assessment: Confronting Climate Change on the Farm
Reductions in greenhouse gas emissions must be complimented with increases in negative emissions in order to stabilize atmospheric carbon dioxide concentrations and prevent catastrophic changes in climate. Soil carbon sequestration on arable lands is a negative emissions technology with high …

Climate Impact Analysis of Direct Air Capture Deployment
Direct air capture (DAC) is a negative emissions technology (NET) that can contribute to mitigating climate change impacts by extracting CO₂ from the atmosphere. Given its low technical maturity, uncertainties persist regarding DAC's cost, scalability, and life-cycle emissions. In this analysis I …

Modeling ocean transport and its biogeochemical impacts at global, regional, and sub-meso scales
… to investigate ocean alkalinity enhancement as a negative emissions technology. We find that local ocean dynamics are crucial for determining optimal alkalinity addition locations that maximize carbon removal, while minimizing adverse ecological impacts. Among the best locations identified are …

Organic Sulfur-Bearing Species as Subsurface Carbon Storage Vectors
To tackle climate change issues, this study investigates whether residual biomass can be converted to a suitable form for permanent subsurface sequestration. Natural sulfurization processes in sedimentary organic matter are investigated as mechanisms to generate biologically refractory …
