RESEARCH PAPERS
Observed Regional Impacts of Marine Heatwaves on Sea-Air CO2 Exchange
Li, C., Burger, F. A., Raible, C., & Frölicher, T. L. (2024). Observed regional impacts of marine heatwaves on air-sea CO2 exchange. Authorea Preprints.
Synopsis: This study analyzes 30 global sea-air flux data sets (1990–2019) to assess the impact of marine heatwaves (MHWs) on oceanic CO₂ uptake. Globally, MHWs reduce CO₂ uptake by 8% (3%–19%). Regionally, the equatorial Pacific sees a 31% reduction in CO₂ release, while oceanic CO₂ uptake decreases by 29% in the Northern Hemisphere and 14% in the Southern Hemisphere during MHWs. In subpolar regions, enhanced carbon uptake occurs, though uncertainties limit a full assessment. High ocean temperatures reduce CO₂ uptake in low-to-mid latitudes.
Tidal influence on carbon dioxide and methane fluxes from tree stems and soils in mangrove forests
Yong, Z. J., Lin, W. J., Lin, C. W., & Lin, H. J. (2024). Tidal influence on carbon dioxide and methane fluxes from tree stems and soils in mangrove forests. Biogeosciences, 21(22), 5247-5260.
Synopsis: Mangroves are vital blue carbon ecosystems, and measuring methane (CH₄) emissions from tree stems can reduce uncertainty in carbon sequestration estimates. This study is the first to measure CH₄ fluxes from both mangrove stems and soils throughout tidal cycles. It found that stems of Avicennia marina and Kandelia obovata were net CO₂ and CH₄ sources, but with significant differences. A. marina showed large variability in CH₄ fluxes, functioning as a CH₄ sink before tidal inundation and a source after ebbing. Tidal influence and species must be considered when quantifying greenhouse gas fluxes.
Exploring the effect of Ulva prolifera components on the biochar carbon sequestration potential
Huang, J., Tan, X., Ali, I., Xie, Y., & Duan, Z. (2024). Exploring the effect of Ulva prolifera components on the biochar carbon sequestration potential. Journal of Cleaner Production, 144373.
Synopsis: The green tide of Ulva prolifera (U. prolifera) has disrupted marine ecosystems, but pyrolysis can convert it into carbon-rich biochar, aiding both green tide management and carbon sequestration. This study examines how U. prolifera’s internal components (fucoidan, cellulose, and protein) affect pyrolysis behavior and biochar’s carbon sequestration potential. Results show that soluble polysaccharides are key in determining biochar properties. Maintaining soluble polysaccharide content below 47.66% can enhance carbon sequestration, offering a sustainable solution for waste management.
Long-term carbon storage in shelf sea sediments reduced by intensive bottom trawling
Zhang, W., Porz, L., Yilmaz, R., Wallmann, K., Spiegel, T., Neumann, A., ... & Schrum, C. (2024). Long-term carbon storage in shelf sea sediments reduced by intensive bottom trawling. Nature Geoscience, 1-9.
Synopsis: Bottom trawling, a major disturbance to seafloor sediments, has uncertain impacts on long-term organic carbon storage. This study examines the relationship between trawling intensity and sedimentary organic carbon in the North Sea. Results show that intense trawling reduces organic carbon storage, while weaker trawling may result in both gains and losses. Cessation of trawling allows for the recovery of carbon stocks, though recovery times for carbon and benthic biomass differ. Management of heavily trawled areas is needed to enhance CO2 sequestration.
A 2-year pure biochar addition enhances soil carbon sequestration and reduces aggregate stability in understory conditions
Wei, J., Li, Y., Li, J., Yan, W., Yin, Q., Jiang, H., ... & Zhang, L. (2024). A 2-year pure biochar addition enhances soil carbon sequestration and reduces aggregate stability in understory conditions. Scientific Reports, 14(1), 1-10.
Synopsis: This study investigates the effects of biochar, derived from rice husks, on soil aggregate formation and carbon sequestration in forest ecosystems. Over two years, biochar was added to plantation soil without additional fertilization or cultivation. Results show that biochar increased soil organic carbon content but negatively impacted soil aggregate stability, particularly reducing larger aggregates. The positive effect on carbon storage was linked more to biochar’s inert carbon content than soil type, suggesting that combining biochar with plant growth is essential for optimal carbon sequestration.
Soil organic and inorganic carbon interactions under tillage and cover cropping determine potential for carbon accumulation in temperate, calcareous soils
Ball, K. R., Guo, Y., Hallett, P. D., Smith, P., Moreno-Ramón, H., Morris, N. L., & Malik, A. A. (2025). Soil organic and inorganic carbon interactions under tillage and cover cropping determine potential for carbon accumulation in temperate, calcareous soils. Soil and Tillage Research, 247, 106369.
Synopsis: This study investigates the impact of cover crops and tillage intensity on soil organic carbon (SOC) and soil inorganic carbon (SIC) stocks in calcareous soils. It finds significant interactions between SOC and SIC, with ploughing enhancing SOC stock at higher SOC:SIC ratios, challenging the view that tillage always reduces SOC. Radish cover crops increased SOC and SIC at shallow depths. A strong correlation between SIC and SOC, along with microbial biomass, suggests complex interactions. The study calls for further research into SOC and SIC dynamics in calcareous soils for effective carbon management.
Productive in disagreement: stakeholder deliberation insights on carbon dioxide removal in Germany
Apergi, M., Hellmich, M., Eberenz, S., Honegger, M., Reinecke, S., & Tänzler, D. (2024). Productive in disagreement: stakeholder deliberation insights on carbon dioxide removal in Germany. Frontiers in Climate, 6, 1465613.
Synopsis: This study explores stakeholder engagement in CDR policy design, focusing on direct air carbon capture and storage (DACCS). Through a workshop and online survey, experts emphasized the importance of context in CDR technology deployment. Participants’ views on DACCS evolved, showing learning during the process. The study stresses the need for deliberative, adaptable policymaking and highlights tradeoffs between climate mitigation and other goals. It advocates for government-backed CDR research and a clear carbon budget to guide future deployment.
Accelerating CO₂ Direct Air Capture Screening for Metal-Organic Frameworks with a Transferable Machine Learning Force Field
Lim, Y., Park, H., Walsh, A., & Kim, J. (2024). Accelerating CO₂ Direct Air Capture Screening for Metal-Organic Frameworks with a Transferable Machine Learning Force Field.
Synopsis: Direct air capture of CO₂ is critical for climate mitigation but faces challenges from low CO₂ concentrations and water vapor. Metal-organic frameworks (MOFs) are promising for DAC due to their high surface area and tunable properties. Identifying optimal MOFs is difficult due to their complexity and the expense of simulations. This study presents the MACE-DAC machine learning force field, tailored for CO₂ and H₂O interactions in MOFs, and introduces a high-throughput screening method to identify optimal MOFs, accelerating DAC research.
Uncertainty in determining carbon dioxide removal potential of biochar
Kane, S., Bin Thaneya, A., Gursel, A. P., Fan, J., Bose, B., Hendrickson, T. P., ... & Horvath, A. (2024). Uncertainty in determining carbon dioxide removal potential of biochar. Environmental Research Letters.
Synopsis: This study quantified uncertainty in biochar's carbon dioxide removal (CDR) using a life-cycle inventory model and Monte Carlo simulation, comparing "best practice" and "poor practice" scenarios. The best practice scenario resulted in a median net removal of 1.4 kg CO₂e/kg biomass, with high certainty of CDR. In contrast, the poor practice scenario showed median net emissions of 0.09 kg CO₂e/kg biomass, with a 66% chance of emitting CO₂. Energy input emissions and bio-oil use accounted for 98% of the variability between scenarios.
Enzyme Assisted Direct Air Capture of carbon dioxide
Zaghini, A., Badino, S., Neun, S., & Westh, P. (2024). Enzyme Assisted Direct Air Capture of carbon dioxide.
Synopsis: This study presents the first systematic data on enzyme-assisted direct air capture (DAC) using carbonic anhydrase (CA). It shows that even very low concentrations of CA significantly accelerate CO₂ absorption. CA also enhances capture efficiency at higher flow rates. The findings suggest that CA's acceleration of carbon capture is more efficient under DAC conditions (short contact times, diluted sources) than with CO₂-rich sources, potentially enabling DAC with low regeneration energy sorbents like carbonate.
Perspectives and challenges of marine carbon dioxide removal
Oschlies, A., Bach, L. T., Fennel, K., Gattuso, J. P., & Mengis, N. (2024). Perspectives and challenges of marine carbon dioxide removal. Frontiers in Climate, 6, 1506181.
Synopsis: The Paris Agreement's goal to limit global warming to below 2°C requires drastic emissions cuts and carbon dioxide removal. With uncertainties surrounding land-based CDR approaches, marine CDR options are gaining attention. This study reviews the potentials, risks, side effects, and challenges of marine CDR, including technical feasibility, governance, and monitoring. It also explores comparisons with direct CO₂ injection into seawater, now prohibited, to evaluate biotic marine CDR approaches.
The Economics of Carbon Dioxide Removal: A Governance Perspective
Edenhofer, O., Franks, M., Gruner, F., Kalkuhl, M., & Lessmann, K. (2024). The Economics of Carbon Dioxide Removal: A Governance Perspective.
Synopsis: This review explores the emerging economic literature on the governance of carbon dioxide removal and its role in climate policy. CDR could transform climate strategies by offering cost-saving technological progress, creating flexibilities that reduce overall costs and help meet temperature targets. It can also address international cooperation issues with lower supply-side leakage. Key challenges include governance, non-permanence of carbon storage, and firm default risks. The review discusses incentive structures and the inclusion of CDR in emissions trading schemes.
Evaluating carbon removal: Integrating technical potential with environmental, social, governance criteria, and sequestration permanence
Mertens, J., Breyer, C., Belmans, R., Gendron, C., Geoffron, P., Fischer, C., ... & Debackere, K. (2024). Evaluating carbon removal: Integrating technical potential with environmental, social, governance criteria, and sequestration permanence. iScience, 27(12).
Synopsis: Climate modeling suggests a need to reduce CO2 emissions by over 90%, with remaining emissions addressed by carbon dioxide removal (CDR) solutions. Sixteen CDR strategies are assessed in this study based on technical potential, environmental, social, and governance (ESG) criteria, and sequestration permanence. The evaluation uses a "quality" measure that combines ESG scores and sequestration timescales to rank the most promising solutions. The study emphasizes the need for further research to mitigate ESG impacts and support effective CDR implementation.
Tetraperoxotitanates for High-Capacity Direct Air Capture of Carbon Dioxide
Bach, K., Garrido Ribó, E., Hirschi, J. S., Mao, Z., Nord, M. T., Zakharov, L. N., ... & Nyman, M. (2024). Tetraperoxotitanates for High-Capacity Direct Air Capture of Carbon Dioxide. Chemistry of Materials.
Synopsis: Materials chemists are crucial in advancing direct air capture (DAC) technologies for CO₂ removal. A family of alkali tetraperoxotitanate materials (A4Ti(O2)4, A = Li, Na, K) was synthesized and studied for DAC reactivity in this study. The K analogue exhibited the highest DAC capacity, absorbing 8.17 mmol CO₂/g sorbent, reaching near maximum capacity in under 10 days. The Li and Na analogues showed delayed reactivity but high capacity. Phase separation in the Na and Li compounds was observed, while the K analogue’s unique composition enabled rapid CO₂ capture, highlighting potential for future DAC innovations.
Identifying drivers of global spatial variability in organic carbon sequestration in tidal marsh sediments
Huyzentruyt, M., Belliard, J. P., Saintilan, N., & Temmerman, S. Identifying Drivers of Global Variability in Organic Carbon Sequestration in Tidal Marsh Sediments. Available at SSRN 4940743.
Synopsis: This study examines the influence of 12 environmental variables on sediment organic carbon content, density, and accumulation rates in 477 tidal marsh sites worldwide. Using Random Forest regression, the study finds that tidal inundation regimes, including tidal range and pattern, primarily explain variability in organic carbon content. Organic carbon density increases with marsh vegetation productivity and cover, while carbon accumulation rates are mainly controlled by sea level rise. The results emphasize that interactions between multiple variables affect carbon sequestration in tidal marshes.
Negative emissions technologies in energy system models and mitigation scenarios - a systematic review
Xie, W., Aryanpur, V., Deane, P., & Daly, H. E. (2025). Negative emissions technologies in energy system models and mitigation scenarios-a systematic review. Applied Energy, 380, 125064.
Synopsis: Modelled scenarios suggest that negative emissions technologies (NETs) like BECCS and DACCS are crucial for limiting global temperature rise and achieving climate goals. This review examines the role of these NETs in decarbonization pathways, highlighting their impact on energy systems and costs. While NETs reduce abatement costs, their reliance can lead to challenges like high marginal abatement costs, temperature overshoot, and fossil fuel lock-in. Achieving net-zero emissions without NETs requires faster, deeper emissions reductions and greater reliance on renewables and energy efficiency.
Legal pathways for China’s blue carbon conservation: a perspective of synergizing ocean and climate rule of law
Li, H., & Liu, Y. (2024). Legal pathways for China’s blue carbon conservation: a perspective of synergizing ocean and climate rule of law. Frontiers in Marine Science, 11, 1497767.
Synopsis: Blue carbon is a critical natural carbon sink for greenhouse gas mitigation. This study explores China's progress and gaps in blue carbon protection, focusing on legislation, enforcement, and judicial practices in ocean governance and climate change mitigation. It proposes legal pathways for improvement, including the formal inclusion of "blue carbon" in legal frameworks, integrating blue carbon into the CCER system, establishing a regulatory body for blue carbon trading, and creating a multi-stakeholder governance model.

“The Soil Carbon Accrual Project, spearheaded by California State University, Chico, in collaboration with California State University, East Bay, is revolutionizing the way we understand and implement sustainable farming practices. As climate change threatens soil health and water availability, this groundbreaking initiative seeks to enhance food security in the U.S. by treating soil as a vital resource. By contrasting conventional and regenerative farming systems across five sites in California, the project aims to identify practices that effectively draw down carbon and bolster soil resilience. This holistic research effort employs cutting-edge technology, including eddy covariance towers and greenhouse gas chambers, to measure carbon dioxide, water flux, nitrous oxide, and methane at an ecosystem scale. These tools, combined with satellite remote-sensing data, provide an undisturbed assessment of greenhouse gas exchanges, offering invaluable insights into the impact of land use practices on soil and water quality. The project also emphasizes the role of soil microbes in carbon sequestration, highlighting the symbiotic relationship between plants and soil biology. Uniquely, the Soil Carbon Accrual Project is not only advancing scientific understanding but also empowering minority students through hands-on research opportunities. By generating real-time data and conducting monthly reviews, the project informs policymakers at local, state, and international levels about the untapped potential of soil carbon accrual. This initiative aims to influence California's agricultural policies, promoting farming practices that align with ecological systems and contribute to climate change mitigation. Through this transformative work, agriculture is poised to play a pivotal role in creating a sustainable future.”
Carbon to Sea Initiative: Growing Support for Ocean-Based Carbon Dioxide Removal Research | WebsEdge Science
“Carbon to Sea is at the forefront of pioneering ocean alkalinity enhancement (OAE) as a groundbreaking climate solution. Recognizing the ocean as the planet's largest carbon vault, Carbon to Sea is harnessing its natural alkalinity to boost CO2 storage and mitigate climate change. By increasing surface alkalinity, they aim to transform CO2 into a form that the ocean can absorb more efficiently, contributing to global and national net-zero carbon targets. As the largest funder in this space, Carbon to Sea collaborates with top scientists, government bodies, and industry leaders to ensure the safety, effectiveness, and measurability of OAE. In Halifax, Carbon to Sea partners with Planetary Technologies and local researchers to conduct field trials, using innovative methods like dispensing alkaline feedstock into Halifax Harbor. This collaboration exemplifies the power of public-private partnerships, with entities like NOAA developing data management practices to support marine carbon dioxide removal research. The initiative is bolstered by bipartisan support in the United States, highlighting the growing recognition of OAE's potential. Carbon to Sea's commitment to transparent community engagement ensures that key stakeholders are informed and involved in the research process. What truly sets Carbon to Sea apart is their unbiased approach. With no financial stake in any specific outcome, they remain open to all possibilities, even if OAE proves non-viable. Their mission is to identify the most effective climate solutions swiftly and responsibly, fostering a vibrant research community that spans disciplines. By building on existing land-based carbon removal knowledge, Carbon to Sea is paving the way for innovative, scalable solutions to combat climate change, offering hope for a sustainable future.”
The GigaTen Ep. 1 Dec 2024 | Tree Media
“Sebastian Manhart updates us on the CDR (carbon dioxide removal) industry in conversation with Leila Conners. The GigaTen is a newsletter that Sebastian posts monthly and Leila thought it would be an interesting conversation to update monthly as well. We think that CDR is important and a unifying pathway as it creates jobs, proposes new ways to manufacture materials and can remove CO2 as needed. **Technical note, Leila's computer decided to lose it's ability to charge and the disk spun so it interrupted the recording bit rate, hence it's blurry, apologies, it is fixed for future episodes.”
