The Cloud Feedback Model Intercomparison Project (CFMIP) contribution to CMIP7 Geoscientific Model Development DOI 10.5194/gmd-19-8693-2026 18 September 2026 Clouds constitute a key uncertainty for climate change projections. The Cloud Feedback Model Intercomparison Project (CFMIP) aims to address this challenge by evaluating and understanding clouds and their impacts on atmospheric circulation, precipitation, and climate sensitivity. The present paper describes the CFMIP experiment protocol for the Coupled Model Intercomparison Project phase 7 (CMIP7), and discusses the accompanying science questions and opportunities for progress.

Ballistic projectile hazard of major explosions and paroxysms at Stromboli (Italy) with uncertainty quantification – Part 2: Conditional and temporal probability maps Natural Hazards and Earth System Sciences DOI 10.5194/nhess-26-4503-2026 17 September 2026 Using historical records and mathematical models, researchers created maps that show the probability of different areas being affected by ballistic fallout from volcanic eruptions in Stromboli, Italy. Hazard maps were developed for both major explosions and paroxysms as well as for the two categories combined together by assuming a relative proportion. By using a temporal model of the explosive events, first probability maps of ballistic fallout in the next 10 and 50 years are finally presented. Read more
The state of diversity, equity, and inclusion in the cloud physics community Geoscience Communication DOI 10.5194/gc-9-415-2026 17 September 2026 A survey and literature metadata analysis from the cloud physics community are used to investigate the state of diversity, equity and inclusion in the cloud physics community. We show the evolution of gender contributions to cloud physics and the inclusion of tropics-based scientists. The publication analysis reveals the rate of men and women dropping out of the field is not different, however, gender balance was better achieved when women led publications compared to men.

Limited atmospheric iron availability increase during the Younger Dryas in the Northern Hemisphere Climate of the Past DOI 10.5194/cp-22-1675-2026 15 September 2026 Ice-core measurements from Greenland suggest that atmospheric iron deposition played a smaller role than previously thought in regulating marine productivity in the iron-limited North Pacific. Despite a strong increase in total iron deposition, the fraction of iron more likely to be available to phytoplankton rose only modestly, pointing to sea-ice extent and sedimentary iron remobilization as potentially more important factors during the last glacial transition.

The Geoengineering Model Intercomparison Project (GeoMIP) contribution to CMIP7 – description of new experimental protocols and preliminary results Geoscientific Model Development DOI 10.5194/gmd-19-8469-2026 11 September 2026 The Geoengineering Model Intercomparison Project is a coordinated international model intercomparison effort aiming to provide robust experimental protocols for simulations of various Solar Radiation Modification (SRM) methods. In this manuscript, we describe a list of novel experiments decided by the community, to be run by climate models to better understand sources of uncertainty in SRM. We also show and discuss some preliminary results from a few climate models. Read more
Imaging deep carbon stocks with complex electrical conductivity Biogeosciences DOI 10.5194/bg-23-6287-2026 11 September 2026 Understanding the role of soil in the storage of organic carbon is critical for a large number of environmental processes. Current practices rely on the drilling and analysis of samples, which is expensive, time consuming and destructive. Here we present a technique able to map soil organic carbon variability using measurements of the electrical properties of the subsurface without drilling. Our results advance soil management strategies to enhance carbon sequestration and storage. Read more
Evaluating surface mass balance variability from climate models using GPS Bedrock Vertical Time Series data The Cryosphere DOI 10.5194/tc-20-5099-2026 10 September 2026 Antarctic surface mass balance (SMB) is a source of major uncertainty in ice-sheet mass balance estimates, but its evaluation remains limited. We introduce a novel method using continuous, bedrock-fixed GPS vertical displacements as a spatially integrated constraint on low-frequency SMB variability over hundreds of kilometres. Applied across Antarctica, it reveals systematic, region-dependent differences with modelled SMB-driven displacements, guiding SMB model refinement. Read more
Cloud liquid water path at the North Slope of Alaska has minimal sensitivity to local meteorology in Arctic winter Atmospheric Chemistry and Physics DOI 10.5194/acp-26-12689-2026 8 September 2026 Liquid-containing Arctic clouds have a strong influence on surface temperature and sea ice extent in winter, but how weather conditions impact cloud cover remains a mystery. This study uses observations from northern Alaska to investigate this relationship. We find that, contrary to expectations, the amount of cloud liquid is remarkably insensitive to temperature, moisture, wind direction, and the large-scale atmospheric flow. Read more
Global hyper-resolution modeling of historical and future groundwater dynamics Earth System Dynamics DOI 10.5194/esd-17-1201-2026 7 September 2026 We simulated how global groundwater levels have changed in the past and how they might change in the future. By improving model accuracy and using hyper-resolution data, we can now see where water tables are falling or rising across the world at 1km resolution. These results help communities and decision-makers plan for more sustainable water use in a changing climate. Read more
Invited perspectives: Towards usable compound event research Natural Hazards and Earth System Sciences DOI 10.5194/nhess-26-4309-2026 7 September 2026 Impacts from extreme weather events may become more severe due to increased likelihood of compounding events under global warming, which challenge present day climate modelling and forecasting capacities. In this perspective we reflect on the usability of compound event research to bridge the gap between academic research and real-world applications. Read more
