Improvement of Daily Temperature Forecasts from a Prediction Market
Published: 2026-10-03
Subjects: Applied Statistics, Atmospheric Sciences, Climate, Meteorology, Natural Resource Economics, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics, Probability, Statistical Methodology, Statistical Models, Statistics and Probability
Prediction markets aggregate and distill the collective views of participants who have a financial stake in being correct. They have been shown to produce more accurate forecasts in realms like election results, which are not easily amenable to mechanistic modeling because they entail forecasting human behavior. It is far less clear that prediction markets should improve the accuracy of [...]
The Influence of Large-Scale Weather Patterns on Potential Wind Energy Fields over Mexico
Published: 2026-09-25
Subjects: Earth Sciences, Oceanography and Atmospheric Sciences and Meteorology, Statistics and Probability
The assessment of wind energy resources in large regions presents a substantial challenge for energy system operators due to the intricacies involved in accurately describing all atmospheric circulation patterns and, even more so, modeling their inherent dynamics. This research primarily aimed to identify the prevailing synoptic weather patterns over continental Mexico and its surrounding [...]
Independent Verification of the European Climate Law's Effect on Nitrogen Dioxide Pollution: A Satellite-Derived, Difference-in-Differences Analysis
Published: 2026-09-05
Subjects: Earth Sciences, Environmental Sciences, Environmental Studies, Geographic Information Sciences, Geography, International and Area Studies, Oceanography and Atmospheric Sciences and Meteorology, Physical and Environmental Geography, Remote Sensing, Spatial Science, Statistics and Probability
Satellite observations make it easy to compare air pollution in countries that adopted a policy with countries that did not. This paper examines what such a comparison identifies. It uses Sentinel-5P TROPOMI tropospheric NO₂ for 2019–2024 and a country-level difference-in-differences (DiD) model of the European Climate Law that compares the EU-27 with nine neighbouring non-EU countries. NO₂ fell [...]
ECOCIDE: Quantifying War-Time Environmental Damage: A Difference-in-Differences Analysis of the Kakhovka Dam Destruction
Published: 2026-09-05
Subjects: Applied Statistics, Biodiversity, Earth Sciences, Environmental Sciences, Geographic Information Sciences, Geography, Human Geography, International and Area Studies, Other Geography, Physical and Environmental Geography, Remote Sensing, Spatial Science, Statistical Methodology, Statistical Models, Statistics and Probability
Abstract: International law organisations are actively looking into declaring "ecocide" -- mass environmental destruction -- as a prosecutable international crime and in September 2024, Vanuatu, Fiji and Samoa submitted a proposed amendment to Rome Statute. No consistent, statistically sound method yet has been developed to document such a claim of harm, however, because prior environmental [...]
Ghost Infrastructure: Historical Industrial Geography and the Persistence of Path-Dependent Accessibility in Bochum, Germany
Published: 2026-09-04
Subjects: Earth Sciences, Environmental Sciences, Environmental Studies, Geographic Information Sciences, Geography, Human Geography, Nature and Society Relations, Other Geography, Remote Sensing, Spatial Science, Statistics and Probability
The complete 69,393 pedestrian street node network from Bochum was used for a Welch's t-test, which revealed as a surprise that street nodes with low accessibility are actually significantly farther from historical industrial sites than street nodes with high accessibility (t=42.887, p<0.00001, Cohen's d=0.589 - medium-to-large effect), which is the opposite of what the original hypothesis [...]
The Cotton Line: Testing the Institutional Persistence of an Erased Colonial Land-Tenure Boundary Across Vidarbha's Agrarian and Vegetation Geography
Published: 2026-09-04
Subjects: Agriculture, Biodiversity, Earth Sciences, Environmental Sciences, Environmental Studies, Geography, International and Area Studies, Statistics and Probability
Can a provincial boundary abolished in 1956 still be detected in today's farmland? In the nineteenth century Berar, in western Vidarbha, was settled under the Ryotwari land-revenue system. The Central Provinces districts to the east were settled under Malguzari. On district lineage the old line matches the present boundary between Amravati and Nagpur Divisions, which I rebuild as a 384.7 km line [...]
The Uncertainty Landscape Beyond Variance
Published: 2026-09-02
Subjects: Environmental Sciences, Forest Management, Mathematics, Statistics and Probability, Terrestrial and Aquatic Ecology
Modern science has become good at measuring uncertainty. Across statistics, artificial intelligence, economics, Earth observation, environmental modelling and decision science, researchers increasingly invoke uncertainty when interpreting evidence, evaluating predictions and supporting decisions. These disciplines often use the word uncertainty to describe conceptually different scientific [...]
Climate change has intensified exceptional El Niño events like the 2026/27 forecast
Published: 2026-08-29
Subjects: Applied Statistics, Climate, Physical Sciences and Mathematics, Statistics and Probability
Extreme El Niño events disrupt weather across much of the globe, with adverse effects on agriculture, fisheries and economic output that persist for several years. Event attribution routinely quantifies the human influence on individual heatwaves, droughts and floods, but its application to the El Niño events that drive many of them has been much more limited. Here we investigate the 2026/27 El [...]
Data Test of a Hydro-Kinematic State Graph for Landslide Forecasting
Published: 2026-08-26
Subjects: Applied Statistics, Earth Sciences, Environmental Monitoring, Environmental Sciences, Geomorphology, Statistics and Probability
A graph model can make landslide-monitoring relationships explicit, but a graph is not automatically more informative than a well-regularized time-series model. This study tests that distinction on the publicly released Lamosano landslide record from northeastern Italy. The processed dataset contains 161 observations of 11-day horizontal InSAR differential displacement and rainfall from 10 April [...]
Does Free Allocation Slow Decarbonization ? Installation-Level Evidence from the EU ETS, Phases III and IV
Published: 2026-06-30
Subjects: Environmental Sciences, Environmental Studies, Physical Sciences and Mathematics, Social and Behavioral Sciences, Statistics and Probability
Installations at high risk of carbon leakage receive free allowances from the European Union Emissions Trading System. Free allowances are allocated to prevent energy-intensive factories from relocating outside the EU. However, whether free allocation slows decarbonization remains an open question. In this paper, I test this question directly. The panel was built at the installation-level. The [...]
Deciphering the morphology of turbiditic lobe bodies according to hierarchy and system size
Published: 2026-06-04
Subjects: Applied Statistics, Earth Sciences, Planetary Sciences, Planetary Sedimentology, Statistics and Probability
Turbiditic lobe bodies (LBs) are the ultimate deposits of source-to-sink systems. Their geometry and architecture vary with depositional environment (marine vs. lacustrine), hierarchy (lobe elements, lobes, lobe complexes), system size (large vs. small) and topographic confinement. Constraining these variations is useful for characterizing the dispersion of sediments, carbon, nutrients, and [...]
Trapped Lee-Wave Resonance Determines Antarctic Megadune Wavelength
Published: 2026-05-23
Subjects: Applied Statistics, Categorical Data Analysis, Design of Experiments and Sample Surveys, Earth Sciences, Fluid Dynamics, Geology, Geomorphology, Geophysics and Seismology, Glaciology, Mineral Physics, Other Earth Sciences, Paleontology, Physics, Planetary Geology, Planetary Geomorphology, Planetary Geophysics and Seismology, Planetary Glaciology, Planetary Hydrology, Planetary Mineral Physics, Planetary Sciences, Planetary Sedimentology, Sedimentology, Statistical Methodology, Statistical Models, Statistics and Probability, Stratigraphy
Snow megadunes cover 5×105 km2 of the East Antarctic plateau, biasing surface mass balance estimates and overprinting ice-core signals—yet their 2–5 km wavelength has lacked a quantitative selection mechanism for two decades. We first falsify the standard formula λ∗ = 2πU0/N through a calibration-free spatial test: eight REMA 2 m tiles across two independent locations at 81.5–82.0°S show no [...]
Stochastic Inversion of geophysical data by sequential Bayesian updating under a non-stationary Gaussian process prior
Published: 2026-05-20
Subjects: Earth Sciences, Statistics and Probability
The acquisition of geophysical data is becoming increasingly important in the context of critical mineral exploration. Geophysical data and inversion product are essential to map many components of the critical mineral system by detecting geophysical anomalies that can be interpreted by expert geologists. However, the inversion of airborne geophysical data acquired along flightlines into [...]
Geodynamic Model Description for Ptolemy’s Germania Magna

Subjects: Analysis, Astrophysics and Astronomy, Dynamical Systems, Dynamic Systems, Earth Sciences, Geology, Geomorphology, Geophysics and Seismology, Mathematics, Other Applied Mathematics, Other Astrophysics and Astronomy, Other Earth Sciences, Other Planetary Sciences, Planetary Geology, Planetary Geophysics and Seismology, Statistical Models, Statistics and Probability, Stratigraphy, Tectonics and Structure, The Sun and the Solar System, Volcanology
This model proposes that the well-documented geodynamic and climatic disruption of the 6th century AD involved a reactivation of the ancient Caledonian Deformation Front (CDF) and the Trans-European Suture Zone (TESZ), most likely triggered by cosmic events in the form of impacts or airbursts. Large-scale inversion tectonics, driven by Alpine compressive forces, are argued to have caused [...]
Reduced geomagnetic shielding increased UV-B radiation at Earth’s surface during the Laschamps Event

Exposure to excess UV-B radiation can harm organisms through DNA damage and oxidative stress, and has likely been a key ecological and evolutionary driver throughout Earth’s history. Here, we show UV-B at Earth’s surface was significantly increased during the Laschamps Event, the last major geomagnetic excursion ca. 41ka BP. During the Laschamps, we find significant and prolonged (lasting [...]
