RESEARCH PAPERS
Assessing the efficacy of river-based ocean alkalinity enhancement for carbon sequestration under high emission pathways
Authors: Xiao-Yuan Zhu, Shasha Li, and Wei-Lei Wang
Synopsis: Ocean alkalinity enhancement mimics natural weathering to boost ocean carbon uptake and counter acidification. Using an Earth System Model under SSP585, researchers simulated 5–10× alkalinity flux increases at river mouths. Results showed modest global pH rises (up to +0.04), ocean DIC gains (up to +9.5 Pmol), and CO₂ drops (up to −51 ppmv). Effects were strongest in coastal, Indian, and North Atlantic Oceans. Yet, even large-scale OAE alone can’t reverse acidification trends, highlighting the need for deeper emission cuts.
Protect young secondary forests for optimum carbon removal
Authors: Nathaniel Robinson, C. Ronnie Drever, David A. Gibbs, Kristine Lister, et al.
Synopsis: Large-scale CO₂ removal is vital to limit severe warming. This study maps ~1-km² growth curves for naturally regrowing forests using 109,708 field plots and 66 environmental factors. Results show carbon removal rates vary 200-fold globally, peaking in 20–40-year-old forests. Protecting young secondary forests can deliver up to 8× more carbon removal per hectare than new regrowth. These maps help identify where forest protection and regrowth can best support global carbon removal goals.
Near-Cryogenic Direct Air Capture using Adsorbents
Authors: Seo-Yul Kim, Akriti Sarswat, Sunghyun Cho, MinGyu Song, Jinsu Kim, Matthew J Realff, et al.
Synopsis: DAC faces cost barriers, but weakly interacting physisorbents offer promise if operated at near-cryogenic temperatures (160–220 K). This study explores coupling DAC with LNG regasification to supply the needed cold energy. Zeolite 13X and CALF-20 showed high CO₂ uptake (4.5–5.5 mmol/g) and strong stability at 195 K, cutting capture costs to ~$68/tonne. Global LNG-DAC integration could capture 103–142 MtCO₂/year by 2050, highlighting its potential as a cost-effective negative-emissions pathway.
Land-based resources for engineered carbon dioxide removal in the United States exceed the expected needs
Authors: Tao Dai, Nathan C. Ellebracht, Elwin Hunter-Sellars, Alvina Aui, Hannah M. Goldstein, et al.
Synopsis: Gigatonne-scale CDR is vital but often land intensive. This study finds the contiguous U.S. has enough suitable land for major CDR pathways while safeguarding food, clean energy, and ecosystems. About 37.6 Mha could support biomass carbon removal and storage (BiCRS), removing ~0.26 GtCO₂/year, while 34 Mha could host wind- and solar-powered direct air capture and storage (DACS) with co-located CO₂ storage, enabling up to 4.8 GtCO₂/year. Strategic siting can balance CDR, energy, and land-use priorities.
Large CO2 removal potential of woody debris preservation in managed forests
Authors: Yiqi Luo, Ning Wei, Xingjie Lu, Yu Zhou, Feng Tao, Quan Quan, Cuijuan Liao, Lifen Jiang, et al.
Synopsis: This study finds that preserving woody debris in managed forests could remove 769–937 GtCO₂ from 2025–2100, averaging 10–12 GtCO₂/year, by extending its soil residence time 100–2,000 years. This durable, low-cost approach—using logging waste, sawmill scraps, and abandoned wood products—could cut global warming by 0.35–0.42 °C. Carbon cycle modeling across three Earth system models supports its potential, underscoring the need for large-scale trials, robust monitoring, and careful assessment of co-benefits and trade-offs.
Seasonally migrating zooplankton strongly enhance Southern Ocean carbon sequestration
Authors: Guang Yang, Angus Atkinson, Evgeny A. Pakhomov, Katrin Schmidt, Weilei Wang, et al.
Synopsis: High-latitude zooplankton play a major role in ocean carbon sequestration through their seasonal vertical migration pump (SVMP), which moves an estimated 65 Mt of carbon annually to depths >500 m in the Southern Ocean. Mesozooplankton drive 80% of this flux, with krill and salps contributing the rest. This process adds 38–56% to the particulate organic carbon flux at 500 m, yet is missing from Earth System Models. Including SVMP is vital for better predictions of ocean carbon storage as polar regions warm.
Winners and losers under hydroxide-based ocean alkalinity enhancement in a Tasmanian plankton community
Authors: Kiyas Kousoulas, Aaron Ferderer, Ruth Eriksen, Lennart T. Bach
Synopsis: This study tested OAE using sodium hydroxide (NaOH) on a coastal Tasmanian plankton community. Raising alkalinity by ~25% boosted the potential CO₂ sink by 21%. In equilibrated conditions (post-CO₂ uptake), plankton showed minimal change. Unequilibrated treatments caused a slight delay in phytoplankton blooms and moderate diatom community shifts, with little zooplankton impact except for lower Noctiluca scintillans abundance. Overall, plankton effects were small relative to OAE’s climate benefits.
Navigating Uncertainty: Legal Considerations for Marine Carbon Dioxide Removal as a Climate Solution
Authors: Tony Cabus
Synopsis: The IPCC says CDR is likely needed to limit warming to 1.5 °C, making mCDR an emerging option. Yet, mCDR’s transboundary effects demand international coordination, which current frameworks like the UNFCCC and Paris Agreement don’t address well. This chapter critiques relying solely on clear-cut science for legal guidance and proposes two pathways: promote transparency and standardisation to use the best science, and strengthen liability rules to manage risks and prevent overuse.
Enhanced CO2 capture using amine-based extractants in liquid-liquid hollow fiber membrane contactors for direct ocean carbon capture
Authors: Seong-Jun Cho, Ho Geun Jeong, Tae Hoon Choi, Soon Jin Kwon, Seong Uk Hong, Jong Hak Kim, et al.
Synopsis: Liquid-liquid hollow fiber membrane contactors (LL-HFMC) offer a promising direct ocean carbon capture (DOC) method, tapping into the ocean’s CO₂ levels, ~150× higher than air, for more cost-effective removal than DAC. This study tested amine-based extractants (MEA, EDA, DETA, TETA) and NaOH using polypropylene membranes. DETA showed the best CO₂ capture performance. Results highlight the need for material and process optimization to scale DOC as an efficient, economical negative emissions technology.
Robust Amine-Grafted Porous Organic Polymer for Highly Selective Carbon Dioxide Capture from Air
Authors: Mahmoud Abdalla, Mohamed Essalhi, Mohamed Hammad Elsayed, Amr Sabbah, et al.
Synopsis: A new solid sorbent, OPTP-8-APTS, shows strong promise for direct air capture (DAC) of CO₂. Made by grafting amine groups onto a hydroxyl-rich porous organic polymer, it retains high CO₂ uptake at low pressures (0.98 mmol/g at 0.15 bar, 298 K) with exceptional CO₂/N₂ selectivity (>900 at 298 K, >2200 at 273 K). Despite lower surface area from pore blocking, strong chemisorption and stability deliver efficient capture, cyclic durability, and reliable performance, highlighting its DAC potential.
Dynamic Assessment of Carbon Emissions and Carbon Sequestration in China's Tourism Industry-Path Optimization and Policy Recommendations Under the "Dual Carbon" Goals
Authors: Yuping Long, Feng Li
Synopsis: From 2000 to 2022, China’s tourism industry saw direct carbon emissions grow from ~43 Mt to ~196 Mt and indirect emissions from ~125 Mt to ~493 Mt. Meanwhile, forest and water body carbon sinks rose modestly, and the tourism sector’s own carbon sink grew slightly from 23.3 Mt to 23.5 Mt, helping offset some emissions. This study highlights the need for greener tourism, ecosystem protection, and better energy efficiency to meet China’s “dual carbon” goals while supporting sustainable tourism growth.
Marine Carbon Dioxide Removal: NOAA Policy Priorities for Efficacy and Risk Reduction
Authors: Jennifer Jordan
Synopsis: As federal support for mCDR accelerates, understanding its ocean and climate impacts lags behind. To ensure responsible mCDR deployment, this piece urges NOAA to prioritize deep-sea research, robust risk analyses, and high-quality measurement, monitoring, reporting, and verification methods. Emphasizing protection of the deep ocean will help NOAA assess mCDR pathways for safety and effectiveness while advancing essential research on ocean system health.
Marine-Based Carbon Dioxide Removal: The Promise and Perils of Ocean Fertilization
Authors: Wil Burns & Philip W. Boyd
Synopsis: CDR is vital for meeting Paris Agreement targets, with marine options like ocean iron fertilization (OIF) drawing interest. OIF boosts phytoplankton growth by adding iron to ocean regions, enhancing CO₂ uptake and potential long-term storage in ocean sediments. This chapter explains OIF’s science, its possible effectiveness, risks of large-scale use, and the challenges of monitoring and verifying carbon sequestration, highlighting its role in a diverse CDR portfolio.
Hybrid Energy-Powered Electrochemical Direct Ocean Capture Model
Authors: James Salvador Niffenegger, Kaitlin Brunik, Todd Deutsch, Michael Lawson and Robert Thresher
Synopsis: Direct ocean capture can supply CO₂ for offshore synthetic fuels or storage, but its performance under variable renewable power needs study. This research develops an open-source Python model for electrodialysis-based DOC plants, simulating electrochemistry, ocean chemistry, and operations under intermittent energy. Coupled with NREL’s H2Integrate tool, it assesses system costs and performance in sites like Texas and Oregon. Findings show tolerant electrochemical systems may work well with variable power, but more research is needed.
Early career ocean professionals declaration on Ocean Negative Carbon Emissions for our ocean and future
Authors: Shenghui Li, Charles I. Addey, Raphaël Roman, Hakase Hayashida, Chunhua Jiang, Chen Hu, et al.
Synopsis: This paper urges faster action on ocean carbon sinks through the Global Ocean Negative Carbon Emissions (Global-ONCE) Programme, vital for reaching net zero by 2050. Beyond science, Global-ONCE champions restoring blue carbon ecosystems with sustainable, inclusive solutions. Early Career Ocean Professionals (ECOPs) drive this mission, blending research, technology, and community action. ECOPs bridge science and society, leading innovation and advocacy to unlock the ocean’s climate potential.
Interactive effects of warming and drought on soil organic carbon sequestration and methane uptake in straw and biochar amended soils: Mechanisms and global implications
Authors: Jitong Lin, Guopeng Liang, Marcela Hernández, Zhiyu Xu, Yinghao Xue, Renhua Sun, et al.
Synopsis: Straw and biochar amendments show opposing soil carbon–methane feedbacks under warming and drought. A meta-analysis and lab study reveal drought cuts CH₄ uptake by 58.9% via reduced pmoA gene abundance and microbial biomass. Warming boosts CH₄ uptake in straw-amended soils (+15.4%) but slashes it in biochar-amended soils (−78.4%) by disrupting methanotrophs. This amendment-specific framework highlights trade-offs between carbon stability and methane sink resilience, guiding climate-smart soil strategies.
West Africa’s Rising Tide: Shaping the Future of Marine Geoengineering Governance
Author: Abdul Hafez Mahamah
Synopsis: Marine geoengineering (MGE) could help tackle greenhouse gases via carbon removal and solar radiation management but brings major environmental and governance challenges. This article reviews global MGE governance under key treaties like UNCLOS, the London Convention/Protocol, the Convention on Biological Diversity, and the climate regime. It highlights the evolving governance landscape in West Africa, where efforts aim to build strong frameworks for responsibly managing these emerging technologies.
Restoration of native saltmarshes enhances carbon sequestration and mitigates warming effects following Spartina alterniflora removal
Authors: Dong Wang, Fabio A. Labra, Hualei Yang, Yuekai Hu, Zhiyuan Zhao, Wenzong Zhou, Lin Yuan
Synopsis: Removing the invasive Spartina alterniflora reduces coastal carbon sinks, with bare mudflats even becoming carbon sources. This study shows that restoring native saltmarshes (Phragmites australis, B. mariqueter) can recover over 70% of lost carbon storage and prevent a shift from climate cooling to warming. Though native marshes store less carbon than S. alterniflora, they far outperform unrestored sites. These findings highlight native saltmarsh restoration as a blue carbon-friendly strategy balancing biodiversity, resilience, and climate goals.

Zooplankton Enhance Southern Ocean Carbon Sequestration | Remove and Reflect Podcast
'This episode explores a research article from "Limnology and Oceanography" that explores the significant contribution of seasonally migrating zooplankton to carbon sequestration in the Southern Ocean, a process termed the Seasonal Vertical Migration Pump (SVMP). The authors quantify that mesozooplankton, krill, and salps collectively transport 65 million tons of carbon annually to depths exceeding 500 meters through their respiration and mortality during overwintering periods. Their findings suggest the SVMP accounts for a substantial portion, 38-56% of modeled and measured particulate organic carbon (POC) flux at 500m, and even 78-103% at 1000m, indicating this active biological process is a crucial, yet often underestimated, component of the ocean's biological carbon pump. The study emphasizes the importance of incorporating the SVMP into Earth System Models for more accurate predictions of ocean carbon storage in a changing climate."
