Emerging low-cloud feedback and adjustment in global satellite observations Atmospheric Chemistry and Physics DOI 10.5194/acp-26-4153-2026 26 March 2026 Recent decades have seen a marked decrease in global low-level cloud cover, leading to more sunlight heating the Earth. This trend is poorly understood, raising the concern that clouds may amplify global warming more than previously thought. We show that the cloud decrease is mostly caused by human forcing on climate, and that it agrees with previous estimates of how clouds respond to decreasing aerosol pollution, increasing greenhouse gas concentration, and their effects on global temperature.

The terrestrial ice margin morphology in Kalaallit Nunaat (Greenland) The Cryosphere DOI 10.5194/tc-20-1797-2026 25 March 2026 Nearly 95% of the Greenland ice margin ends on land, where meltwater leaves the ice to supply surrounding ecosystems. Here we show that nearly 30% of this land-terminating margin ends in extremely steep, often vertical sections, previously only described in individual locations. Less than 20% are shallow ramps. Knowledge of these margin shapes and their locations allows us to further investigate what they can potentially tell us about the current ice sheet health and its future evolution. Read more
Limited influence of bedrock strength on river profiles: the dominant role of sediment dynamics Earth Surface Dynamics DOI 10.5194/esurf-14-247-2026 24 March 2026 Bedrock strength in bedrock river is often seen as controlling incision rates and river profiles, natural changes in rock type do not always match slope changes. In the Abukuma River basin, Japan, we measured bedrock strength and despite large strength differences, slopes were nearly uniform. Numerical tests showed that the model, which includes sediment cover and erosion effects, best explained river profiles. Thus, sediment plays a greater role than bedrock strength in shaping river profiles. Read more
A lesson in preparedness: assessing the effectiveness of low-cost post-wildfire flood protection measures for the catastrophic flood in Kineta, Greece Hydrology and Earth System Sciences DOI 10.5194/hess-30-1487-2026 23 March 2026 Wildfires can exacerbate flood risks, as seen in a Greek town where heavy rain caused significant damage following a recent fire. This study examined how simple, low-cost protection measures, such as Log Erosion Barriers and wooden check-dams, might have mitigated the damage. Using models and real data, we found these measures could have lowered the flood's impact by 25 % and saved millions in damage. Therefore, investing in such prevention can be cheaper than paying for repairs after disasters. Read more
Thermodynamic concepts used in physical oceanography Ocean Science DOI 10.5194/os-22-923-2026 20 March 2026 Marine science has adopted the Conservative Temperature and Absolute Salinity variables of TEOS-10 (the International Thermodynamic Equation Of Seawater - 2010), and here we review the thermodynamic theory behind this change of practice. Ocean heat content and the poleward oceanic heat flux are accurately evaluated using Conservative Temperature. Absolute Salinity incorporates the variable composition of seawater, and ocean models now need to incorporate this feature. The available methods for evaluating approximately neutral surfaces are also discussed. Read more
Mapping the fertosphere's phosphorus availability distribution in a field trial using a novel diffusive gradients in thin-films (fDGT) technique SOIL DOI 10.5194/soil-12-253-2026 17 March 2026 The first report of the field deployment of a new soil sampling device to investigate phosphorus (P) fertiliser strategies. The approach was combined with X-ray fluorescence microscopy to produce 2D spatially-resolved P availability maps to visualise distinct differences between new and conventional P fertilisers. This technique shows great potential for optimising P application and material sciences development; potentially leading to improved productivity and more sustainable P fertiliser use. Read more
The impact of Aeolus observations on wind and rainfall predictions Weather and Climate Dynamics DOI 10.5194/wcd-7-489-2026 12 March 2026 This study shows that Aeolus satellite wind lidar observations significantly improve wind forecasts and that these improvements lead to more accurate rainfall predictions, particularly at longer lead times and during winter seasons in the extratropics. The benefits are likely due to better representation of large-scale atmospheric features such as jet streams and Rossby waves, highlighting Aeolus's value for numerical weather prediction. Read more
Numerical experiments of cloud seeding for mitigating localization of heavy rainfall: a case study of Mesoscale Convective System in Japan Natural Hazards and Earth System Sciences DOI 10.5194/nhess-26-1287-2026 11 March 2026 Can disasters caused by extreme rainfall be mitigated through human intervention? Using numerical simulations reproducing a devastating rainfall event, we show that injecting large amounts of ice nuclei into convective clouds can trigger an “overseeding” effect that suppresses raindrop growth. This process disperses intense rainfall downstream and reduces peak 3-hour rainfall by up to 32 %, highlighting the potential of cloud seeding as a new strategy for mitigating heavy rainfall disasters.

The role of cyclonic eddies in the detachment and separation of Loop Current eddies Ocean Science DOI 10.5194/os-22-821-2026 10 March 2026 We analyze 29 years of satellite altimetry to investigate the detachment of Loop Current Eddies in the Gulf of Mexico. Over half of the Loop Current eddies reattach within a month, while 42 % separate and drift westward. Detachment requires the Loop Current to reach the Mississippi Fan and is strongly influenced by cyclonic eddies, whose configuration determines whether an eddy separates or reattaches to the Loop Current.

Feldspar alteration by disequilibrium CO2-H2O fluids in reservoir sandstones: implications for CCS Solid Earth DOI 10.5194/se-17-407-2026 9 March 2026 Contrary to current CCS (Carbon Capture and Storage) models, reaction experiments conducted at subsurface stress and temperature conditions reveal that feldspars, common, reactive grains in sandstone reservoirs, can undergo significant chemical and mechanical changes when exposed to CO₂ enriched water. These chemo-mechanical processes, including grain fracturing, dissolution, and clay precipitation, can modify fluid pathways and rock strength, potentially reducing reservoir productivity and increasing leakage risk.
