Topography constrains the climatic response of treeline migration in Taiwan's subalpine forests

Ecography, EarlyView.
Treelines are moving upslope, but the rates and drivers differ among different regions, globally. Many studies have examined the relationship between treeline movement and climate change, particularly rising temperature, while the role of topographical factors has received much less attention, despite the longstanding recognition of its importance.

Transmission line trip faults under extreme snow and ice conditions: a case study

Energy Informatics
Extreme weather events, particularly snow and ice storms, present significant threats to the stability and reliability of high-voltage transmission lines, leading to substantial disruptions in power supply.

Faster growing and more functionally diverse: global change alters functional trait composition of mountain plant communities in the European Alps

Ecography, EarlyView.
Understanding how global change reshapes mountain plant communities is essential for predicting biodiversity and ecosystem function in a warming world. Using resurvey data from over 1400 non‐forest vegetation plots across the European Alps, we show that community‐weighted means of key functional traits capturing important dimensions of plant ecological

Reliability Analysis of a Steel Frame

Acta Polytechnica, 2002
A steel frame with haunches is designed according to Eurocodes. The frame is exposed to self-weight, snow, and wind actions. Lateral-torsional buckling appears to represent the most critical criterion, which is considered as a basis for the limit state ...

Assessment of Automated Snow Cover Detection at High Solar Zenith Angles with PROBA-V

Remote Sensing, 2016
Changes in the snow cover extent are both a cause and a consequence of climate change. Optical remote sensing with heliosynchronous satellites currently provides snow cover data at high spatial resolution with daily revisiting time.

Global threats, local opportunities: ice‐related landforms provide refugia for high‐elevation plants and arthropods

Ecography, EarlyView.
Ice‐related landforms in mountain areas have been hypothesized to play a key role in the survival of cold‐adapted species threatened by climate change. However, our understanding of such landforms acting as refugia remains speculative. Here we analyse occurrence data, collected through a standardized sampling at 471 sampling points across the European ...

Cloud-Gap Filtering for Reliable MSG-SEVIRI-Based Snow Cover Records

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Abstract. Snow cover is a key variable for climate monitoring and hydrological applications, yet optical satellite observations are strongly limited by cloud contamination, particularly during winter. The EUMETSAT H SAF H34 snow product derived from MSG-SEVIRI uses the unique 15-minute temporal resolution over the full SEVIRI disc to clear the clouds ...

A Novel Multilevel Conceptual Framework for Flood Risk Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Globally, flood risk is increasing as climate change progresses. Contemporary flood risk management practice often utilises hydrodynamic modelling (for hazard risk assessments), social vulnerability assessments, and risk communications in silo, which fragments evidence‐based decision‐making for effective flood risk management. We hence develop

GeoAI Dataset for Training a Deep Learning-based GEMS Snow Detection Model [PDF]

Geo Data
The Geostationary Environment Monitoring Spectrometer (GEMS) observes air quality across East Asia from an altitude of approximately 36,000 km, analyzing the spatiotemporal distribution of atmospheric pollutants that spread beyond localized regions. GEMS

Collective Grievance Promotes Collective Action and Aggressive Intergroup Inclinations Through Dehumanization Among Conservative Members of Dominant Groups

European Journal of Social Psychology, EarlyView.
ABSTRACT Previous research has focused on disadvantaged groups seeking social change, overlooking how dominant groups mobilize to preserve the status quo. Across three studies (two correlational, one experimental), we explored how collective grievance—the feeling of being or having been collectively wronged by an outgroup—drives system‐preserving ...
