Reliable national CO2 inventories underpin the Paris Agreement’s Enhanced Transparency 1national emissions modelling as leave-country-out (LOCO) estimation: predicting a country’s per-capita CO2 from eight-year trajectories of energy and socioeconomic covariates, with no access to its own emission history. Using Global Carbon Budget and Energy Institute data harmonized by Our World in Data, we [...]
Biodiversity conservation policies alter the solution space of climate mitigation scenarios
Published: 2026-09-08
Subjects: Environmental Sciences
Conserving biodiversity while mitigating climate change is one of the defining sustainability challenges of this century. Paris-aligned mitigation pathways rely heavily on forest restoration and bioenergy with carbon capture and storage (BECCS). While forest restoration can simultaneously enhance wildlife habitat and increase carbon sequestration, large-scale biomass production for BECCS may [...]

Published: 2026-09-08
Subjects: Environmental Sciences, Environmental Studies, Natural Resources and Conservation, Natural Resources Management and Policy, Nature and Society Relations, Social and Behavioral Sciences, Sustainability, Water Resource Management
Water allocation decisions in Mexico are taken municipality by municipality, yet water scarcity is assessed at national or basin scale. We operationalize a safe and just operating space for water for each of the 67 municipalities of Chihuahua, Mexico's largest and driest mining state, with both bounds drawn from national law rather than imposed by the analyst: an ecological ceiling equal to the [...]

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 [...]

Small islands are widely assumed to face a compounding climate risk: high physical exposure to sea-level rise, layered on top of degrading natural coastal defenses. That assumption is rarely tested against independent, multi-temporal evidence, and rarely broken down by ecosystem type — so I tested it directly, across five islands spanning three ocean basins: Maldives, Lakshadweep, Seychelles, [...]
Ghost Infrastructure: Historical Industrial Geography and the Persistence of Path-Dependent Accessibility in Bochum, Germany

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 [...]
Stolen Strata: Quantifying the Anthropogenic Erasure of Kashmir's Karewa Terraces and Its Threat to the Saffron Economy
Published: 2026-09-04

Published: 2026-09-04
Subjects: Agriculture, Biodiversity, Earth Sciences, Environmental Sciences, Environmental Studies, Geography, International and Area Studies, Statistics and Probability
Are there 150-year-old institutional legacies measurable in the 21st century as a spatial signature, in patterns of vegetation phenology (cotton signatures), agrarian labor structure, land use and land surface temperature? That is the core question this paper addresses and the design is not a 'before'-'after', it's a 'spatial discontinuity' test to see if there is still a measurable gap across an [...]

The importance of ice shelf melt rate distributions in modelling of Antarctic ice loss
Published: 2026-09-03
Subjects: Environmental Sciences, Glaciology, Oceanography, Physical Sciences and Mathematics
Ocean-induced basal melting of ice shelves is a major cause of Antarctic ice loss. It is well known that the magnitude of this melt is an important factor to consider when modelling the future evolution of the ice sheet, and values of total melt volume or mean melt rates are often quoted for ice shelves. The finer detail of the distribution of this melt is usually given less attention. Here we [...]
