We explored whether adding crushed volcanic rock and charcoal to soil could help store inorganic carbon, improve plant growth and reduce harmful metals in crops. The crushed rock did not increase plant growth or inorganic carbon in soil and nutrients released from the rock may have moved into other stable soil forms rather than forming carbonates. In contrast, charcoal improved plant growth and reduced metal uptake. Using both rocks and charcoal together offered no extra observable benefits.

Enhanced rock weathering is a nature based negative emission technology, that permanently stores CO2. It requires rock-flour to be added to arable land with the help of farmers. To be eligible for carbon credits calls for a simple but scientifically solid, so called, Monitoring, Reporting & Verification” (MRV). We demonstrate that the commonly used carbon-based accounting is ill-suited to close the balance in open systems such as arable land, and argue for cation-based accounting strategy.

To test enhanced weathering's efficacy, we ran a two-year greenhouse study under warm, wet conditions, comparing several rock additives across farm soils. We tracked alkalinity and cation soil pools. Soil type was decisive: acidic, low-buffer soils exported more additional alkalinity, while alkaline or pH neutral soils retained it in cation pools. The results point to where enhanced weathering can deliver durable carbon removal and underscore the need for long, well-controlled trials.

We explored whether adding basalt and beneficial fungi to soil could improve soil health and crop growth. Basalt improved soil chemistry, confirming its role as a soil improver, while the fungi had little effect. Crop yield remained unchanged, showing that benefits depend on soil type. Our study helps clarify how soil amendments work and when they may support farming and climate solutions.

A mesocosm experiment was set up to investigate how maize responds to the application of basalt, concrete fines, and steel slag, using a dose–response approach. Biomass increased with basalt application but did not change with concrete fines or steel slag, except for increased tassel biomass. Mg, Ca, and Si generally increased in the crops, whereas toxic trace elements remained unaffected or even decreased in the plants. Overall, crops were positively affected by the application of silicate materials.

Crushed volcanic rock has been proposed as a way to remove carbon dioxide from the air while improving soil quality. We tested this idea by growing maize in soil with and without the rock and with earthworms. The rock raised soil nutrients, and earthworms boosted these effects. Plant growth stayed similar, but some metals built up in roots. This approach could support farming and climate goals, yet food safety risks must be managed.

Ocean alkalinity enhancement has gained popularity to capture carbon dioxide. Yet, most laboratory experiments were run for short term, with strong mixing and without carbon dioxide exchange. In this research, a new setup tried to reproduce a more natural mixing. Overall, alkalinity remained stable for 6 months, thanks to the carbon dioxide invasion which differs from previous research. Hence, potential pitfalls identified in laboratory studies may not be at play in real world application.

Large-scale atmospheric pathways connecting climate across latitudes are poorly documented in the past. Using a high-resolution spatial and temporal reconstruction of the evolution of the Southern Hemisphere Westerlies since the Last Glacial Maximum and comparing it with the evolution of the Intertropical Convergence Zone, we identified the dominant atmospheric pathways that shaped past South American climate.

We created the first detailed map of how much agricultural lime has been used across the United States from 1930 to 1987. Lime helps improve soil health and crop growth. Our study shows that how and where lime is used depends on climate, soil, and farming practices. By using machine learning, we found patterns that help explain these differences. This work helps us better understand the environmental role of lime and its impact on farming and climate.

Ocean alkalinity enhancement (OAE) is being assessed for its potential to absorb atmospheric CO2 and store it for a long time. OAE still needs comprehensive assessment of its safety and effectiveness. We studied an idealised OAE application in a natural low-nutrient ecosystem over 1 month. Our results showed that biogeochemical functioning remained mostly stable but that the long-term capability for storing carbon may be limited at high alkalinity concentration.

Alkalinity leakage limits the efficiency of ocean alkalinity enhancement. Drivers of this process remain unquantified, restricting accurate assessments. The induced runaway process can be modeled using surface area and aragonite oversaturation as key factors. This study proposes a framework for improving predictability of alkalinity loss due to runaway precipitation, emphasizing the need for field experiments to validate theoretical models concerning dilution and particle sinking processes.

Recent studies described the precipitation of carbonates as a result of alkalinity enhancement in seawater, which could adversely affect the carbon sequestration potential of ocean alkalinity enhancement (OAE) approaches. By conducting experiments in natural seawater, this study observed uniform patterns during the triggered runaway carbonate precipitation, which allow the prediction of safe and efficient local application levels of OAE scenarios.

This study examines about 8000 groundwater level (GWL) time series from five continents to explore similarities in groundwater systems at different scales. Statistical metrics and machine learning techniques are applied to identify common GWL dynamics patterns and analyze their controlling factors. The study also highlights the potential and limitations of this data-driven approach to improve our understanding of groundwater recharge and discharge processes.

We analyzed how leaf wax hydrogen isotopes in continental and marine sediments respond to climate along one of the strongest aridity gradients in the world, from hyperarid to humid, along Chile. We found that under extreme aridity, the relationship between hydrogen isotopes in waxes and climate is non-linear, suggesting that we should be careful when reconstructing past hydrological changes using leaf wax hydrogen isotopes so as to avoid overestimating how much the climate has changed.

Riverine alkalinity in the silicate-dominated headwater catchment at subarctic Iskorasfjellet, northern Norway, was almost entirely derived from weathering of minor carbonate occurrences in the riparian zone. The uphill catchment appeared limited by insufficient contact time of weathering agents and weatherable material. Further, alkalinity increased with decreasing permafrost extent. Thus, with climate change, alkalinity generation is expected to increase in this permafrost-degrading landscape.

Short summary
Effective water quality management in the Elbe River from 1984 to 2018 significantly reduced CO2 emissions, particularly after Germany's reunification. Key factors in the reduction include organic carbon removal and nutrient management, with nitrogen control being more critical than phosphorus for the restoration of ecosystem capacity. Unpredictable influxes of organic carbon and the relocation of emissions from wastewater treatment can cause uncertainties for CO2 removals.

In this paper we present the carbon cycle component of the newly developed fast Earth system model CLIMBER-X. The model can be run with interactive atmospheric CO2 to investigate the feedbacks between climate and the carbon cycle on temporal scales ranging from decades to > 100 000 years. CLIMBER-X is expected to be a useful tool for studying past climate–carbon cycle changes and for the investigation of the long-term future evolution of the Earth system.

CO2 can be stored in the ocean via increasing alkalinity of ocean water. Alkalinity can be created via dissolution of alkaline materials, like limestone or soda. Presented research studies boundaries for increasing alkalinity in seawater. The best way to increase alkalinity was found using an equilibrated solution, for example as produced from reactors. Adding particles for dissolution into seawater on the other hand produces the risk of losing alkalinity and degassing of CO2 to the atmosphere.

We assess the impact of riverine nutrients and carbon (C) on projected marine primary production (PP) and C uptake using a fully coupled Earth system model. Riverine inputs alleviate nutrient limitation and thus lessen the projected PP decline by up to 0.7 Pg C yr−1 globally. The effect of increased riverine C may be larger than the effect of nutrient inputs in the future on the projected ocean C uptake, while in the historical period increased nutrient inputs are considered the largest driver.

In subarctic grassland on a geothermal warming gradient, we found large reductions in topsoil carbon stocks, with carbon stocks linearly declining with warming intensity. Most importantly, however, we observed that soil carbon stocks stabilised within 5 years of warming and remained unaffected by warming thereafter, even after > 50 years of warming. Moreover, in contrast to the large topsoil carbon losses, subsoil carbon stocks remained unaffected after > 50 years of soil warming.

Zea mays grows in mesocosms with different soil nutrition levels. At low phosphorus (P) availability, leaf physiological activity initially decreased strongly. P stress decreased over the season. Arbuscular mycorrhizal fungi (AMF) symbiosis increased over the season. AMF symbiosis is most likely responsible for gradual reduction in P stress.

We provide a comprehensive dataset of vertical profiles of photosynthesis and important leaf traits, including leaf N and P concentrations, from two 3-year, large-scale nutrient addition experiments conducted in two tropical rainforests in French Guiana. These data present a unique source of information to further improve model representations of the roles of N and P, and other leaf nutrients, in photosynthesis in tropical forests.

Short summary
Our study explores Enhanced Weathering (EW) using basalt rock dust to combat climate change. We treated maize-planted mesocosms with varying basalt amounts and monitored them for 101 d. Surprisingly, we found no significant realized inorganic CO2 removal. However, rock weathering was evident through increased exchangeable bases. While inorganic CO2 removal was not realized within this experiment, basalt amendment may enhance soil health and potentially long-term carbon sequestration.
