Restoration of forestry-drained oligotrophic peatlands can bring climate change mitigation within a few decades
Published: 2025-09-29
Subjects: Life Sciences
Introduction: Assessment of climate mitigation of peatland restoration is urgently needed, but data on greenhouse gas (GHG) fluxes from restored forestry-drained peatlands (FDP) is sparse. Using surrogate values from pristine peatlands, some studies have indicated long-lasting warming effect of restoration especially of nutrient-poor FDPs, while studies considering realized conditions and data [...]
Artificial Intelligence in the polycrisis: fueling or fighting flames?
Published: 2025-04-16
Subjects: Environmental Studies
Artificial intelligence (AI) is increasingly entangled with the polycrisis—persistent, interconnected disruptions shaping the Anthropocene. Using the Anthropocene Traps framework, we analyze 14 structural, self-reinforcing dynamics, revealing how AI both reinforces and potentially counteracts polycrisis. While AI may enhance information gathering, efficiency, and ecological research, it also [...]
ANALYSING THE PLANT VARIETY PROTECTION WITH RESPECT TO FOOD SECURITY IN INDIAN CONTEXT
Published: 2025-04-16
Subjects: Education, Social and Behavioral Sciences
Ending hunger, achieving food security and sustainable agriculture is the second Sustainable Development Goal (SDG) out of seventeen SDGs of United Nations and it aims to ensure food security and nutrition to each individual globally. Plant varieties protection (PVP)and plant breeders’ rights protection agreements and laws like International Union for the Protection of New varieties of Plant [...]
Evaluating the role of observational uncertainty in climate impact assessments: Temperature-driven yellow fever risk in South America
Published: 2025-04-18
Subjects: Medicine and Health Sciences
Global gridded temperature data sets (GGTDs) vary in their information sources, quality control procedures, generation techniques, and spatial-temporal resolutions, introducing observational uncertainty. This uncertainty is critical not only for studies on current climate conditions but also for future climate change projections, where observational data sets are used for bias correction and [...]
Oxic conditions in shallow marine settings during the Permian-Triassic Mass Extinction
Published: 2025-04-17
Subjects: Physical Sciences and Mathematics
The concept that ultra-shallow marine anoxia was a major cause of the Permian-Triassic mass extinction was partly based on sections from the Dolomites (Italy). We test this hypothesis by re-examining the Dolomites record, utilizing an updated redox sensitive trace metal (V, U and Mo) approach, combined with Fe speciation and Th/U ratios, and paleontological observations. Redox sensitive trace [...]
A controlled release experiment for investigating methane measurement performance at landfills
Published: 2025-04-18
Subjects: Earth Sciences
We assessed the performance of various methane measurement solutions in landfill applications. A measurement solution is defined as a system or market offering that quantifies and/or localizes emissions. Our study involved full-scale multipoint- and area-source (dispersed) controlled releases of methane from the ground surface of a closed 25-hectare landfill with collection system and a [...]
Floods and Water Management in Chiang Mai and the Upper Ping catchment, Northern Thailand
Published: 2025-04-17
Subjects: Geomorphology, Hydrology, Sedimentology, Water Resource Management
The city of Chiang Mai, Northern Thailand has been subject to regular major floods in the past couple of decades. In this review, we provide some background information on the hydrology of Upper Ping river catchment, the hydrogeology of the Chiang Mai – Lamphun basin, historical records of hydrological events in the area and more recent depictions of major floods. In the second part of this [...]
A Simple Method for Designing Infiltration Low Impact Development Techniques Considering Effects of Urbanization and Climate Change
Published: 2024-10-12
Subjects: Civil Engineering, Environmental Engineering, Hydraulic Engineering
Infiltration-focused low-impact development (LID) solutions aim to gradually absorb surface runoff, playing a critical role in reducing both peak flow rates and runoff volumes. These systems are commonly designed with specific surface areas and controlled ponding depths to provide sufficient storage capacity that counteracts the increased runoff resulting from urban expansion. Nevertheless, [...]
Simulation of multiply scattered elastic waves with 3D wave-equation and radiative transfer equation for displacements and their gradients
Published: 2025-04-19
Subjects: Physical Sciences and Mathematics
In this study, we investigate the behavior of seismic waves in a highly scattering medium using numerical simulations of the full wavefield, based on Spectral Element Method solutions of the wave equation. The simulated 3D elastic medium was designed with Von Kármán-correlated heterogeneity, providing a realistic representation of the complexities present in natural seismic environments. We [...]
Heatwave Characteristics in Different Ecosystems across Türkiye: Historical and Future Insights from CMIP6 Simulations
Published: 2025-04-19
Subjects: Atmospheric Sciences, Climate, Meteorology
Heatwaves pose significant threats to diverse sectors, including agriculture and forestry. This extreme weather event is characterized by prolonged periods of exceptionally high air temperatures and has caused substantial economic damage and affecting millions. During heatwave events, agricultural and forest lands are affected by intensified thermal stress and water scarcity, impacting plant [...]
Temporal dynamics of biotic homogenization and differentiation across marine fish communities
Published: 2025-04-20
Subjects: Marine Biology
Humans have transformed ecosystems through habitat modification, harvesting, species introduction, and climate change. Changes in species distribution and composition are often thought to induce biotic homogenization, defined as a decline in spatial beta diversity through time. However, it is unclear whether homogenization is common in ocean ecosystems and if changes in beta diversity exhibit [...]
Evaluation of climatic and non-climatic influence on malaria prevalence in the Upper River Region of The Gambia
Published: 2025-04-20
Subjects: Public Health
Despite the scale-up of intervention, malaria remains a burden in the Upper River Region of The Gambia. Climate changes and non-climatic conditions can substantially influence malaria prevalence, and further affect the coverage of preventive interventions. This work aimed at exploring the different climatic and non-climatic risk factors associated with malaria. A descriptive research method using [...]
North American ice sheet persistence during past warm periods should inform future projections
Published: 2025-04-23
Subjects: Physical Sciences and Mathematics
How fast sea level rises in the next century will depend on how fast the Antarctic Ice Sheet responds to warming. Projections of future Antarctic Ice Sheet behavior are shaped by the assumption that peak sea level during past warm periods occurred after ice sheets had disappeared from North America. Here we present emerging evidence from paleoceanography and allied disciplines to argue that North [...]

Instability and atmospheric CO2 anomalies in the recent global carbon cycle
Published: 2025-10-17
Subjects: Physical Sciences and Mathematics
A major instability occurred in the recent global carbon cycle. It manifests as a major CO2 anomaly between 2009 and 2015 that is clearly seen in the residuals from generalized exponential growth, or equivalent quadratic curves through Taylor expansion, or 10-year running means. Our findings contradict recent assertions of the stability of the recent global carbon cycle based on growth rate [...]
