ClimTip-GML: A global bias-corrected and downscaled dataset for assessing impacts of climate tipping events
Here, we present ClimTip-GML, the first globally bias-corrected and downscaled climate dataset for impact assessment of large-scale tipping scenarios, comprising eight key variables at 0.25{\deg} spatial resolution from three general circulation models (GCMs): CESM1-CAM5, HadGEM3-GC31-MM, and MPI-ESM1-2-HR.
PreprintDice ser un gran avanceUso en el mundo realTime Distribution of Heavy Rainfall in Brazil: Empirical Huff Curves from 290,164 Sub-Daily Storm Events
Here, we develop the first national-scale empirical Huff curves for Brazil using sub-daily rainfall observations.
PreprintUso en el mundo realDivergent trends in post-landfall decay of strong and weak tropical cyclones
Here we identify an intensity-dependent divergence in global trends of tropical cyclone post-landfall decay.
Revista con revisión por paresUso en el mundo realAn eastward-propagating coupled mode amplifying the early growth of extreme El Niño events
Here, by analyzing the 1982/1983, 1997/1998, and 2015/2016 events together with a large ensemble of climate model simulations, we identify an unusually early and reproducible ocean-atmosphere precursor to extreme El Niño: a slow, eastward-propagating coupled mode that develops in the western-central equatorial Pacific during boreal winter and spring.
Revista con revisión por paresUso en el mundo realThermally driven CO 2 adsorption/desorption and its effect on soil respiration
These results, combined with field data from the Mojave Desert, demonstrate that adsorption causes negative nocturnal CO 2 fluxes, while desorption during the day leads to positive fluxes.
Revista con revisión por paresAfirmaciones fuertes, leer con cuidadoPublic support for novel carbon removal hinges on procedural and distributive fairness
We find that support hinges on procedural and distributive fairness: opening planning processes to public and expert scrutiny, benefit sharing and not-for-profit arrangements consistently increase public support for carbon removal across all countries and technologies.
Revista con revisión por paresUso en el mundo realFácil de leerExtreme North American heatwaves in 1941 and 2021 drove widespread but contrasting impacts
Both qualitative and quantitative analyses offer insights into how and why select impacts of the two heatwaves differed, including different continental-scale heatwave evolution and post-heatwave weather, policy responses that were related to co-occurring crises of World War II and the COVID-19 pandemic, and differing social norms, daily tidal cycles, technology, engineering, and infrastructure.
Revista con revisión por paresFácil de leerCompound drought–heat wave hazards are concentrated in US regions with multiple social vulnerabilities and agricultural dependence
Regions facing greater socioeconomic challenges, including poverty, high agricultural employment, and health-related vulnerabilities, experience notably higher CDHW risks.
Revista con revisión por paresUso en el mundo realA dataset of one-dimensional idealized probabilistic fields
We present a first-of-its-kind idealized probabilistic dataset composed of one-dimensional cases aimed at analyzing the behavior and properties of verification methods for probabilistic forecasts and comparing their behavior.
PreprintModel-data synthesis of benthic isotopes suggests a warmer Miocene Climatic Optimum
Our approach yields a maximum likelihood estimate of MCO global mean surface temperature of 7.5∘C above preindustrial, significantly warmer than previous benthic δ18O-based reconstructions, implying a higher MCO-derived estimate of Earth system sensitivity.
Revista con revisión por paresCollinear UV–mid-IR cross-validation updates HO 2 self-reaction kinetics and implications for tropospheric HO x and H 2 O 2
The resulting rate coefficients are consistently higher than current NASA/JPL recommendations, by ~50% under humid boundary-layer conditions and by up to a factor of two under upper-tropospheric conditions, owing primarily to revised pressure-dependent and water-enhanced contributions.
Revista con revisión por paresUso en el mundo realArctic lightning during solar wind disturbance
These findings demonstrate that solar-wind influence on lightning activity is not driven by a single mechanism, but is a sporadic, regionally structured phenomenon strictly constrained by local meteorological conditions and, surprisingly, emerges only on long timescales.
Revista con revisión por paresSpace-time signatures of surface warming accelerations since 1970
Our results show that there are coherent space-time systems of acceleration in warming and shift toward warming since 1970 that are consistent across multiple surface temperature datasets.
Revista con revisión por paresFácil de leerFAST-ML: A Hybrid Physics-Machine Learning Framework for Tropical Cyclone Intensity Forecasting
We present FAST-ML, a hybrid framework that bridges data-driven efficiency with physical constraints.

West-WRF AI 2-km reproduces observed precipitation-intensity distributions, retains fine-scale spectral variability, and produces sharper narrow coastal precipitation bands and localized, terrain-sensitive extremes.
PreprintUso en el mundo realA memory of Paleozoic to Quaternary Greenhouse climates recorded in Southern African regolith
Mixing of minerals generations reveals here some of the main periods of warm and wet climate that affected the Southeastern African continent during the last 400 Myr.
Revista con revisión por paresHydrological Constraints on Temperature Sensitivities of Precipitation Frequency and Intensity
We find a linear relationship between co-variations of rainfall frequency and intensity, where the slope is a hydrological sensitivity determined by the dryness and storage indices and the intercept is a forcing term associated with changes in moisture convergence, potential evapotranspiration, and effective water-storage capacity.
PreprintA strong Pacific Walker Circulation during the Little Ice Age
We present a third line of evidence, the surface-to-thermocline temperature difference in the Indonesian Seas, which was smaller during the LIA than during the Medieval Climate Anomaly (approximately 950 to 1250 CE), suggesting a deeper thermocline, in agreement with hydroclimate evidence for a stronger LIA Walker Circulation.
Revista con revisión por paresPrecursors, Pathways, and State-Dependent Reliability of Long-range ENSO Prediction in the CESM2 Seasonal-to-Multiyear Large Ensemble
These findings suggest that improving the initial Pacific state and cross-basin coupling fidelity in GCMs may help improve ENSO prediction.
