Brent et al. (2026): Strategic research priorities for marine climate interventions in Australia

Kerryn Brent, Lennart Bach, Andrew Lenton, Bronte Tilbrook, Tanveer M. Adyel, Harris Anderson, Mark Baird, Erin Bohensky, Philip Boyd, Damon Britton, Joseph Crosswell, Perran Cook et al., IN: Australasian Journal of Environmental Management, https://doi.org/10.1080/18366503.2026.2665493

Marine climate interventions (mCIs) are ocean-based approaches to support climate change mitigation and/or adaptation. Carbon dioxide removal approaches focus on reducing atmospheric greenhouse gas concentrations through enhancing ocean carbon uptake and storage. Solar radiation management proposals aim to shade and cool vulnerable marine ecosystems. How research is progressed into these two types of mCIs over the coming decade will be critical to enable responsible research and deployment, ensuring that Australian scientists and policymakers can make informed decisions.

Kurokawa et al. (2026): Direct evidence for enhanced mineral weathering in cropland verified by quantitative X-ray powder diffraction

Kohei Kurokawa, Atsushi Nakao, Kazuki Azuma, Hodaka Tomita, Katashi Kubo, Kazuki Nomura and Junta Yanai, IN: Applied Geochemistry, https://doi.org/10.1016/j.apgeochem.2026.106869

Enhanced rock weathering (ERW) is a promising carbon dioxide (CO₂) removal (CDR) strategy that involves applying powdered rocks such as basalt to croplands to accelerate the natural weathering of rock minerals. However, despite numerous recent field investigations, direct evidence for the weathering of rock minerals in soils is lacking because most studies rely on cation budgets to estimate ERW-induced CDR. In this study, buckwheat was cultivated for 2.5 months in plots with and without basalt powder applied at a rate of 150 t ha⁻¹, and the decrease in basaltic mineral contents of the soils during the cultivation period was measured using quantitative X-ray powder diffraction (XRPD).

Anschütz et al. (2026): Not one shoe fits all: Applicability of hydrodynamic models for the simulation of ocean alkalinity enhancement in the Baltic Sea

Anna-Adriana Anschütz, Thomas Neumann, Peter Holtermann and Hagen Radtke, IN: Journal of Marine Systems, https://doi.org/10.1016/j.jmarsys.2026.104226

Ocean alkalinity enhancement (OAE) has become the focus of intensive research as a potential method for future carbon dioxide removal (CDR). In the Baltic Sea, the deposition of alkaline minerals on the seafloor is one of the considered options, as their dissolution raises local alkalinity. Once the additional alkalinity reaches the sea surface, it increases the ocean’s potential for uptake of atmospheric CO₂. A reliable estimation of the vertical transport of dissolved constituents is therefore essential for a model’s applicability to ocean alkalinisation research. While concentrations of seawater ingredients are often straightforward to measure, the corresponding transports of these ingredients by advection and turbulent diffusion are not. Based on an example from the study of ocean alkalinity enhancement, the authors demonstrate that these transport estimates can exhibit a considerable range of uncertainty even when well-calibrated models are employed. To evaluate the reliability of such estimates by current physical ocean models, they recreated a passive tracer release experiment in the Gotland Deep (Baltic Sea) in three model setups: two hydrodynamic models with differing vertical coordinate systems, including two resolutions for one of the models.

Scott-Buechler (2026): Removing carbon, governing deployment: public perceptions of industry and community roles in U.S. carbon dioxide removal policy

Celina Scott-Buechler, IN: Climatic Change, https://doi.org/10.1007/s10584-026-04177-6

Public perceptions of carbon dioxide removal (CDR) governance are likely to influence its potential as a climate mitigation strategy but remain underexplored. In a nationally representative survey experiment of 1,488 US adults, the author examines attitudes towards CDR policy and implementation, focusing on governance preferences, perceived moral hazard, and the role of the fossil fuel industry.

Almajed et al. (2026): Quantifying capital-energy trade-offs in bipolar membrane electrodialysis for atmospheric and oceanic carbon removal

Hussain M. Almajed, Bri-Mathias Hodge and Wilson A. Smith, IN: Joule, https://doi.org/10.1016/j.joule.2026.04.008

Coupling bipolar membrane electrodialysis (BPMED) with direct air capture (DAC) and direct ocean capture (DOC) presents promising carbon removal pathways. The authors develop, validate, and integrate process and techno-economic models to assess this integration under variable power scenarios.

Probst & Egli (2026): Fixing carbon credits requires a new financing model

Benedict S Probst and Florian Egli, IN: PNAS Nexus, https://doi.org/10.1093/pnasnexus/pgag117

Carbon-crediting mechanisms could play a critical role in achieving net zero, yet growing evidence shows that many offset projects lack environmental integrity. Achieving geological net zero requires balancing residual fossil fuel–based emissions with permanent carbon dioxide removal (CDR), making the scale-up of CDR essential. However, current discussions on improving carbon-crediting mechanisms have focused too narrowly on implementation challenges, such as refining standards or monitoring systems. The authors argue that scaling permanent carbon removal requires a new financing model to address market barriers.

Lopez-Reyes et al. (2026): Decarbonizing desert greenhouse crop production with direct air capture–based CO₂ enrichment

Zulma Lopez-Reyes, Wesley Hopwood, Jonathan Jones, Rod Wing, Raffaella Sordella, Carlos Grande and Rebekah Waller, IN: npj Climate Action, https://doi.org/10.1038/s44264-026-00149-6

High-tech greenhouses in hot-desert climates deliver high yields with minimal water and land footprint but are constrained by costly, emissions-intensive carbon dioxide (CO₂) enrichment supplied via trucked liquid-CO₂. The authors evaluate two adsorption-based direct air capture (DAC) systems—temperature-vacuum-swing (TVSA) and moisture-swing (MSA)—as on-site enrichment alternatives, benchmarking against conventional liquid-CO₂ supply. Using integrated techno-economic and life-cycle assessment models, they show that DAC systems achieve comparable levelized costs and lower climate-change burdens for high-tech greenhouse cherry tomato and lettuce crop production systems by avoiding transport-related emissions.

Nature – Li et al. (2026): Enhanced response of extreme compound events to cumulative CO₂ emissions

Jun Li, Yao Zhang, Philippe Ciais, Hongying Zhang, Zhaoli Wang, Hongwu Tang and Shilong Piao, IN: Nature, https://doi.org/10.1038/s41586-026-10544-1

Compound events—such as concurrent hot–wet and drought–heat extremes—are among the most consequential climate hazards on Earth1,2,3,4 and are projected to become more severe under warming. Although the transient mean temperature response to cumulative CO₂ emissions has been well quantified5,6,7,8, the corresponding response of compound events remains less clear. Here the authors show that the response of the transient compound events to cumulative CO₂ emissions (TCoRE), defined as the change in event frequency per unit of cumulative CO₂ emissions, is strongly dependent on the background frequency of compound events.

Navarro et al. (2026): Climate and ecological constraints of cultivating bioenergy crops for climate mitigation in tropical regions

Robert Fofrich Navarro, Alcen Chiu and Elsa M Ordway, IN: PNAS Nexus, https://doi.org/10.1093/pnasnexus/pgag123

Negative-emission approaches, such as bioenergy with carbon capture and storage (BECCS), are expected to play a crucial role in mitigating climate change. However, the capacity for biological carbon sequestration under changing climatic conditions remains highly uncertain, particularly in historically warm regions. Although bioenergy can be derived from various biological materials, nearly all operational BECCS facilities capture CO₂ from bioethanol fermentation. The authors therefore assess the share of bioenergy crop cultivation that will be exposed to future climate conditions beyond their historically safe climate space (SCS), focusing on tropical regions.
