Invited Perspectives: Science for Comprehensive Disaster and Climate Risk Management Natural Hazards and Earth System Sciences DOI 10.5194/nhess-26-4589-2026 24 September 2026 We explore five core challenges that need to be addressed in order to move towards the Comprehensive Disaster and Climate Risk Management approach. This approach has been proposed within the newly emerging paradigm of a more holistic approach to managing the risks associated with climatic and/or non-climatic hazards and non-climatic risk drivers. We elaborate on each challenge, discuss why they matter for comprehensive disaster risk management, and provide ideas of how to overcome them. Read more
The North American CORDEX-CMIP6 WRF evaluation run: comparing historical simulations from 25 km to convection-permitting scales Geoscientific Model Development DOI 10.5194/gmd-19-8995-2026 23 September 2026 This study presents a new 12 km CORDEX (Coordinated Regional Downscaling Experiment )-CMIP6 (Coupled Model Intercomparison Project) WRF (Weather Research and Forecasting) simulation for North America, compared against an earlier 25 km CMIP5 version and a 4 km convection-permitting simulation. The updated run reduces temperature and precipitation biases, improves precipitation timing, and better captures tropical cyclone intensity. Extreme precipitation at 12 km closely matches convection-permitting results, offering a practical resolution for regional climate assessment. Read more
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
