The viability of green hydrogen projects can be assessed using the proposed multi-level integrated framework of open-source tools that enables quantitative and qualitative comparison of the green hydrogen production potential and generation costs of different sites, as demonstrated by a case study in Australia.

The transition of gold nanoparticles to gold-bearing veinlets could occur by solid-state pipe-diffusion and elemental migration from the interior of pyrite grains to the surfaces, according to direct observations and density functional theory calculations

Agricultural ponds in the USA and Australia emit nearly double the amount of methane reported in their national greenhouse gas inventories, according to estimates derived from a combination of flux measurements from the literature and observations.

During the Last Glacial Maximum, the Peruvian oxygen minimum zone was similar in extent but weaker by about 40% than during the Late Holocene, suggest records of foraminiferal pore density from the Peruvian ocean margin.

The stable carbon isotopic composition of particulate matter in mixed phytoplankton assemblages in a marginal sea is more strongly correlated with temperature than CO₂ concentration, according to observations from the deep chlorophyll maxima in the southern Yellow Sea

Distinct distributions of microbial communities are present across potential acid sulfate soils, the overlying transition zone and actual sulfate soils, according to genomic and transcriptomic analyses of an acid sulfate soil profile in Finland.

Warming of the subsurface Southern Ocean played only a minor role in shrinking Antarctic Sea ice extent in 2016, but was critical for the persistence of negative anomalies between 2016 and 2021, according to coupled climate model simulations partially constrained by observations.

Ambient seismic noise interferometry combined with a quantitative stress model can be used to determine changes in seismic wave velocity and, by extension, other geotechnical parameters which are critical to monitoring tailings dam performance

Space weathering of graphite yields unnoticeable reflectance changes over 40 Earth years on the surface of Mercury, according to the time-series remote-sensing images acquired during the MESSENGER mission.

Combining hydrogen production derived from mixed plastic waste with carbon capture and storage technologies is technically and economically feasible at current market conditions, according to a techno-economic analysis and life cycle assessment.

Reactions of depleted, reduced peridotite with oxidised volatile-rich melts can explain several contentious rock assemblages sampled by kimberlites from the metasomatised zone at the base of the lithosphere, according to high pressure laboratory experiments.

Decadal to centennial variations in the intensity of the Asian summer monsoon were coupled with Antarctic temperatures during the Dansgaard–Oeschger 8 and Heinrich 4 intervals, according to a speleothem oxygen isotope record from Yongxing Cave, China.

Extreme precipitation over the coastal Gulf of Mexico following Hurricane Harvey led to calcium carbonate undersaturation and ecosystem-level acidification, according to observational analyses from Galveston Bay, Texas, in 2017 and 2018.

Transitioning to a hydrogen economy has the potential to mitigate carbon dioxide emissions. The hydrogen leakage rate and the production pathways appear, based on simulations with a global model, as key leverages to reach a clear climate benefit from a large-scale transition to a hydrogen economy.

Deep-water cycling enables a self-regulated mantle evolution which maintains a near-constant mantle viscosity and can explain why magmatism has continued despite planetary cooling throughout Earth’s history, suggests data-constrained numerical modelling

Detection of sedimentary facies and their boundaries can be automated effectively by a combination of a machine learning classification model and feature engineering, suggesting analyses of X-ray fluorescence profiles of sedimentary cores from North Sea tidal flats in Germany

Atmospheric wakes caused by offshore wind farms built in the North Sea may affect marine ecosystems, both at the surface ocean and at the seafloor, according to a numerical modeling study.

Multilateral crop trading that maximizes the system benefit and minimizes the inequality level of water-land benefits could effectively mitigate both nutrient surplus and footprint, according to an integrated evaluation model for China and central Asia.

Western-central European summers were about 6–10 °C cooler with roughly 30–70% less precipitation during last glacial climate oscillations compared to modern values, according to quantitative paleoclimate estimates based on earthworm calcite granules.

Lagged responses of the terrestrial carbon cycle to atmospheric carbon dioxide concentration may enhance climate change mitigation for decades after net-zero emission targets are met, according to analyses of simulations from an ensemble of CMIP6 Earth system models
