RESEARCH PAPERS
Plankton food web structure and productivity under ocean alkalinity enhancement
Sánchez, N., Goldenberg, S. U., Brüggemann, D., Jaspers, C., Taucher, J., & Riebesell, U. (2024). Plankton food web structure and productivity under ocean alkalinity enhancement. Science Advances, 10(49), eado0264.
Synopsis: Ocean alkalinity enhancement (OAE) is a CO₂ removal method, but its environmental safety is uncertain. Testing OAE in subtropical North Atlantic mesocosms in this study showed zooplankton and food webs were resistant and tolerant to the intervention. Short-term impacts on zooplankton reproduction and productivity were observed but had no population-level effects or reduced nutritional value for fish. While this OAE application was safe, more intense OAE or other ecosystems may face risks, highlighting the need for cautious scaling.
Attention and positive sentiments towards carbon dioxide removal have grown on social media over the past decade
Repke, T., Müller-Hansen, F., Cox, E., & Minx, J. C. (2024). Attention and positive sentiments towards carbon dioxide removal have grown on social media over the past decade. Communications Earth and Environment.
Synopsis: Scaling up CO₂ removal is vital for net-zero goals, requiring public engagement and understanding. Analyzing Twitter data (2010–2022), attention to CDR grew exponentially, with increasingly positive discourse, except for BECCS. Conventional CDR methods are most discussed and viewed positively. Infrequent users focus on biological sinks, while frequent users engage with novel methods. This study highlights evolving awareness and perceptions, complementing surveys to guide socially acceptable CDR deployment.
Restoring mangroves lost by aquaculture offers large blue carbon benefits
Jiang, Y., Zhang, Z., Friess, D. A., Li, Y., Zhang, Z., Xin, R., ... & Li, Y. (2024). Restoring mangroves lost by aquaculture offers large blue carbon benefits. One Earth.
Synopsis: Mangrove forests, with high carbon densities, have been extensively deforested by aquaculture. However, aquaculture areas present opportunities for restoration, as many retain suitable biophysical conditions. This study assesses restoration suitability in China and Southeast Asia, finding that 60% of lost mangroves are feasible for restoration, potentially removing 84 Mt CO₂. These findings offer spatially explicit guidance for restoration planning and emphasize mangrove restoration's role in climate change mitigation efforts.
The state of carbon dioxide removal through afforestation and reforestation
Pongratz, J., Schwingshackl, C., Gasser, T., Castanho, A., & Grassi, G. (2024). The state of carbon dioxide removal through afforestation and reforestation.
Synopsis: Afforestation and reforestation (A/R) are key for large-scale carbon dioxide removal (CDR) but lack precise global tracking. Using bookkeeping models and corrected national greenhouse gas inventories (NGHGIs), A/R CDR is estimated at 1,860 MtCO₂/year (2013–2022), with the largest contributions from China, the USA, Brazil, and Russia. Despite providing 99% of global CDR, current levels fall short of offsetting residual emissions, emphasizing the need to expand forests or adopt other CDR methods.
Current rates of CO2 removal due to rock weathering in the UK
Harrington, K. J., Henderson, G. M., & Hilton, R. G. (2024). Current rates of CO2 removal due to rock weathering in the UK. Science of the Total Environment, 957, 177458.
Synopsis: Chemical weathering of silicate and carbonate rocks removes CO₂ naturally, but its contribution in the UK is poorly quantified due to complex geology and land use. Using river chemistry data from 52 UK catchments, a geochemical model estimated a net CO₂ removal of 4.5 MtCO₂/yr, accounting for sulphuric acid weathering. This is comparable to lower-end Enhanced Weathering (EW) targets, which could more than double natural fluxes. EW's impact on river chemistry should be considered before implementation, study recommended.
Biochar effects on aggregation and carbon-nitrogen retention in different-sized aggregates of clay and loam soils: A meta-analysis
Yuan, X., Ban, G., Luo, Y., Wang, J., Peng, D., Liang, R., ... & Wang, Z. (2025). Biochar effects on aggregation and carbon-nitrogen retention in different-sized aggregates of clay and loam soils: A meta-analysis. Soil and Tillage Research, 247, 106365.
Synopsis: Biochar enhances soil aggregation, carbon sequestration, and nitrogen retention, with varying effects across soil textures. Analyzing 534 experiments in this study, biochar improved macroaggregate formation, water stability, and organic matter content. Clay soils showed better aggregation responses, while loam soils saw significant organic carbon increases. Optimal biochar rates are 10–20 t/ha for loam and 20–40 t/ha for clay soils. Long-term use boosts macroaggregate-associated carbon, improving soil health and sustainability.
Cross-species Comparison of Ultramafic Rock Bio-accelerated Weathering Performance
Plante, L., Klug, J. D., Lee, J., Hornby, A., Adair, J., Marecos, S., ... & Barstow, B. (2024). Cross-species Comparison of Ultramafic Rock Bio-accelerated Weathering Performance. bioRxiv, 2024-11.
Synopsis: This study compares the ability of three microbes—Gluconobacter oxydans, Sphingomonas desiccabilis, and Penicillium simplicissimum—to dissolve the ultramafic rock dunite for carbon mineralization. G. oxydans outperformed the other two microbes, producing the most acidic biolixiviant and extracting the most magnesium, along with other critical metals. The findings suggest G. oxydans is ideal for bio-accelerated weathering and propose using cellulosic hydrolysate as a cost-effective substitute for glucose in biolixiviant production.
A comparative analysis of GHG inventories and ecosystems carbon absorption in Brazil
Miguel da Costa, L., Davitt, A., Volpato, G., Costa de Mendonça, G., Panosso. A, R, La Scala, N. A comparative analysis of GHG inventories and ecosystems carbon absorption in Brazil. Science of The Total Environment, 958.
Synopsis: Global temperature rise is driven by greenhouse gas (GHG) emissions, primarily from fossil fuels globally and forestry, land use, and agriculture in Brazil. These sectors, while emitting GHGs, also absorb carbon, aiding climate mitigation. Comparing Climate TRACE and SEEG inventories from 2015–2022 in this study, discrepancies of up to 1 Gt CO₂-eq emerged, mainly from forestry. In Caatinga, rising precipitation and photosynthesis boosted removals, contributing ~50% of Brazil's 2022 total. Stopping deforestation can enhance net-zero goals.
Source-to-sink pathways of dissolved organic carbon in the river–estuary–ocean continuum: a modeling investigation
Yao, J., Chen, Z., Ge, J., & Zhang, W. (2024). Source-to-Sink Pathways of Dissolved Organic Carbon in the River-Estuary-Ocean Continuum: A Modeling Investigation. Biogeosciences Discussions, 2024, 1-29.
Synopsis: Dissolved organic carbon (DOC) transport in estuaries remains poorly understood. Using a physics–biogeochemistry model, this study analyzed DOC cycling in the Changjiang Estuary. DOC comprises terrigenous (tDOC) and marine (mDOC) types, with summer distributions influenced by hydrodynamics and biogeochemical processes, while winter is hydrodynamics-driven. The estuary exports DOC, with mDOC contributing 69% due to local processes. The model highlights DOC source-sink dynamics and its potential for broader applications.
Applying negative emissions technologies in the superfoods sector: How far are we from achieving a carbon neutral spirulina production?
Fernández-Ríos, A., Butnar, I., Laso, J., Borrion, A., Aldaco, R., & Margallo, M. (2024). Applying negative emissions technologies in the ‘superfoods’ sector: How far are we from achieving a carbon neutral spirulina production?.
Synopsis: Environmental degradation affects food and forestry systems, but offers opportunities for carbon removal and alternative nutrient sources. This study evaluates two carbon capture techniques for spirulina production: using CO₂ from beer fermentation (SP_BRW) and direct air carbon capture (SP_DACC). Both methods show improved environmental performance, with carbon footprints of 1.03 and 1.37 tons CO₂ eq./year, respectively, reducing emissions by up to 51.1% and 47%. These results highlight the potential for carbon accounting in the superfoods sector.
Carbon dioxide removal could perpetuate community-scale inequalities of U.S. air pollution in net-zero scenarios
Bergero, C., Cheng, J., Zhang, Q., Ou, Y., McJeon, H., Nock, D., ... & Davis, S. J. (2024). Carbon dioxide removal could perpetuate community-scale inequalities of US air pollution in net-zero scenarios.
Synopsis: Net-zero pathways reduce GHG emissions and improve air quality, with the magnitude of health benefits depending on carbon dioxide removal (CDR) levels. Using models to analyze community-scale PM2.5 impacts across the U.S., high- and low-CDR scenarios reduce PM2.5-related deaths in 2050 from 200,000 to 160,000 and 130,000, respectively. The low-CDR pathway offers greater health benefits, especially for non-white and low-income groups, suggesting that large-scale CDR could conflict with equitable health benefits.
Electrochemical recovery of high-purity calcium carbonate and magnesium hydroxide from brine via carbon mineralization
Lu, P., Ochonma, P., Kim, M., Walike, C., Sunkara, A., & Gadikota, G. (2024). Electrochemical recovery of high-purity calcium carbonate and magnesium hydroxide from brine via carbon mineralization. MRS Bulletin, 1-12.
Synopsis: Rising anthropogenic CO2 levels challenge Earth's ecological balance, but renewable energy offers a unique opportunity to remove CO2 by converting it into solid carbonates. This study develops an electrochemical approach to selectively precipitate magnesium hydroxide (Mg(OH)2) and calcium carbonate (CaCO3) using titanium mesh electrodes under ambient conditions. With yields up to 90% and purities over 96%, this method is adaptable for resource recovery from seawater and wastewater, showing potential for industrial CO2 removal, though sulfate presence affects product purity.
Fire effects on phytolith carbon sequestration
Li, R., Gu, Z., Vachula, R. S., Dong, H., Xu, M., Chen, X., ... & Sun, Y. (2024). Fire effects on phytolith carbon sequestration. Scientific Reports, 14(1), 1-14.
Synopsis: This study examines the impact of open fire on phytolith carbon sequestration. By comparing the carbon and dissolved silicon content of phytoliths from six grass species and a pine forest, the study found that fire increased carbon content in topsoil phytoliths while reducing their solubility. The effects varied between plant species and with fire exposure, highlighting fire's role in altering phytolith carbon content, solubility, and preservation in soils. This provides new insights into fire’s influence on phytolith carbon sequestration.
Iron’s role in soil organic carbon (de)stabilization in mangroves under land use change
Ruiz, F., Bernardino, A. F., Queiroz, H. M., Otero, X. L., Rumpel, C., & Ferreira, T. O. (2024). Iron’s role in soil organic carbon (de) stabilization in mangroves under land use change. Nature Communications, 15(1), 10433.
Synopsis: Mangroves are critical for carbon storage but are threatened by land use changes (LUC). In Amazonian mangroves, iron-mediated organomineral interactions (FeOMIs) play a key role in stabilizing soil organic carbon (SOC), particularly through poorly crystalline Fe oxides, which protect labile SOC from degradation. LUC, such as conversion to pastures or shrimp ponds, disrupts FeOMIs, leading to SOC loss. These changes undermine mangroves' carbon sequestration potential, with global biogeochemical impacts.
Design and optimization of biochar production and incorporating it into green roofs for CO2 capturing
Nasr, D., Al Sarraf, N., & Bachawati, M. E. (2024). Design and optimization of biochar production and incorporating it into green roofs for CO2 capturing. In E3S Web of Conferences (Vol. 585, p. 01005). EDP Sciences.
Synopsis: Biochar, a stable carbon-rich product, enhances soil quality and air purification, making it ideal for green roofs. Green roofs offer environmental, social, and economic benefits, such as reducing energy use, urban heat, and stormwater runoff while improving biodiversity and air quality. Adding biochar to green roofs increases CO₂ capture compared to traditional designs, study suggested. Using Aspen Plus, modeling shows biochar production from cotton stalks generates char, oil, and gas, with the latter used to produce electricity for the plant.
Exploring the factors influencing the carbon sink function of coastal wetlands in the Yellow River Delta
Tang, Z., Wang, D., Tian, X., Bi, X., Zhou, Z., Luo, F., ... & Li, J. (2024). Exploring the factors influencing the carbon sink function of coastal wetlands in the Yellow River Delta. Scientific Reports, 14(1), 28938.
Synopsis: This study quantifies soil organic carbon (SOC) and vegetation carbon sequestration (VCS) in the Yellow River Delta (YRD) from 1999 to 2020, using landscape metrics and the CASA model. Findings show that natural wetlands and non-wetlands decreased, while artificial wetlands increased. VCS rose from 0.2309 Tg C in 2000 to 0.3681 Tg C in 2020, with total carbon sequestration of 6.0952 Tg C. Vegetation cover had the greatest impact on carbon sinks, followed by precipitation and biodiversity, highlighting key factors for coastal wetland management.

Software engineer as part of DOE Earthshot project at Yale Center For Natural Carbon Capture
"YSE is currently seeking to hire a Software Engineer at Yale University with both modeling expertise and skills to build a public facing online modeling platform. The Software Engineer will have two primary tasks: to focus on integrating models from each domain to create a fully integrated inorganic carbon model, and creating an online platform that will allow others to use this newly developed land-to-sea carbon model. While we do not expect the Software Engineer to have expertise in all of the models listed above, they should have a strong programming background, a solid understanding of basic biogeochemical cycling across the land-water-air continuum, modeling experience, the ability to learn how these models can best feed into each other, and expertise building online user-friendly interfaces. This position will be responsible for creating documentation, examples, and online training materials. In collaboration with other developers and scientists they will assist with organization and teaching at workshops and attend various meetings. This position offers an enriching work experience and an opportunity to work with scientists from around the country on open-source software systems.
This position will work on “Global Ocean And Land Alkalinization” (GOAL-A), a new Department of Energy (DOE) Earth Shot project that aims to create a fully connected global inorganic carbon model. This new project is a collaboration between Yale, Georgia Tech, Princeton, and Texas A&M. The project will center on improving and integrating biogeochemical models in several “domains” including soils, streams and rivers, the near coast, and the open ocean; conducting both within domain modeling and global earth system modeling. The domain models include SCEPTER, ATS, DRRN, ROMS, MOM6, MITgcm, E3SM, CESM, GFDL. While the scope is global, early analyses will validate this modeling framework using data from the Mississippi watershed and Gulf of Mexico. This project will improve our understanding of how carbon dioxide removal practices like enhanced rock weathering and ocean alkalinity enhancement will affect atmospheric carbon dioxide concentrations, ecosystems, flow path chemistry, ocean pH, and domain-specific alkalinization."

Doctoral Opportunity—Rock, charcoal and compost: Investigating synergistic effects of enhanced rock weathering, biochar, and compost amendments for soil remediation and carbon sequestration
"Global declines in soil health, fertility and carbon sequestration potential are of substantial concern. The limits of increased agricultural performance through inorganic fertiliser and seed technologies are being reached, necessitating new approaches to feed an expanding global population. In addition, to give us a realistic chance of meeting international climate targets, reductions in greenhouse gas (GHG) emissions are needed, alongside a concerted effort to maximise carbon dioxide removal technologies.
Substantial previous work has gone into assessing the efficacy of various organic and non-traditional soil amendments, particularly composts, that provide a readily available source of labile organic material, and biochar, that provides long-term carbon burial, nutrient loss reductions, and potentially GHG emission reductions. More recently the addition of silicate rock dust to soils has been introduced as a potential management practice. This ‘enhanced rock weathering’ (ERW) is a geoengineering technique that enhances the natural mechanism of silicate weathering. This process produces carbonate (alongside other ionic constituents) that can then be precipitated in the oceans to be sequestered in long-term carbon sinks. ERW is estimated to be able to potentially sequester 1-2 billon tonnes of atmospheric CO2-C per year by 2100.
While our understanding of these amendments in isolation is continually and rapidly evolving, there has been little consideration of synergistic effects¬ – additive or potentially inhibitive – when these amendments are co-deployed. In theory, potentially negative aspects such as the addition of unwanted harmful ions such as heavy metals, often associated with ERW, may be mitigated by biochar through its ability to increase cation exchange capacity and / or increase plant growth and nutrient uptake rates. Biochar can also enable soil carbon sequestration via its stable organic carbon pool, while enhancing soil microbial activity and help create more suitable conditions for weathering processes.
The concurrent additions of compost, biochar and ERW strategies potentially provide a suite of improvements to soil health and do so without conflicting with the need for agricultural land use for food production. In this PhD we will quantify synergistic effects of these key soil amendments, allowing us to determine best practice for application to achieve various management improvement goals, including agronomic performance, soil heath and structure, soil organic matter concentration, and carbon sequestration."
