Younger Dryas glacier advances in the tropical Andes driven by increased precipitation

Scientific Reports
There is currently a debate about the timing and drivers of former glacier behaviour and climate change in the tropical Andes. Using 10Be dating we determined the ages of 21 boulders on moraines in the Santa Cruz Valley, Peru (∼10°S, altitudes ~ 4100 to ~

Extrapolation strategy matters when transferring ecological niche models: new visualization tools for informed decisions

Ecography, EarlyView.
Abstract Ecological niche models (ENMs) are commonly used to predict species' potential distributions across space and time, allowing researchers and practitioners to assess invasion risk, estimate the impacts of future climate change, and reconstruct past distributions.

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 ...

Recent changes in area and thickness of Torngat Mountain glaciers (northern Labrador, Canada) [PDF]

The Cryosphere, 2017
The Torngat Mountains National Park, northern Labrador, Canada, contains more than 120 small glaciers: the only remaining glaciers in continental northeast North America.

Internal structure of a Himalayan debris-covered glacier revealed by borehole optical televiewing

Journal of Glaciology, 2023
Characterising the structures within glaciers can give unique insight into ice motion processes. On debris-covered glaciers, traditional structural glaciological mapping is challenging because the lower glacier is hidden by the supraglacial debris layer.

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

THE GLACIER COMPLEXES OF THE MOUNTAIN MASSIFS OF THE NORTH-WEST OF INNER ASIA AND THEIR DYNAMICS

Geography, Environment, Sustainability, 2011
The subject of this paper is the glaciation of the mountain massifs Mongun-Taiga, Tavan-Boghd-Ola, Turgeni-Nuru, and Harhira-Nuru. The glaciation is represented mostly by small forms that sometimes form a single complex of dome-shaped peaks. According to

Modeling the impacts of grazing management on livestock behavior and performance: A case study in the Peruvian Andes

Grassland Research, EarlyView.
Our modeling study shows that livestock management strongly influences grazing behavior and animal performance in the Peruvian Andes. Furthermore, adjusting stocking rates and improving animal distribution can enhance forage intake and body condition while increasing forage biomass.

Detection, Attribution and Projection of Precipitation Structure Changes Over Northwest China

International Journal of Climatology, EarlyView.
The precipitation structure shows a change trend of ‘the frequency of light precipitation decreased and the intensity of heavy precipitation increased’; attribution analysis shows that greenhouse gas forcing (GHG) is the main driving factor of precipitation structure change, and the model underestimates its impact, while aerosol forcing (AER) and ...

Changing Water Resources in the Indus Basin: A Multi‐Model Budyko‐Based Analysis

International Journal of Climatology, EarlyView.
Budyko‐based analysis evaluates historical (1962–2005) and future hydroclimatic change across the Indus River Basin. Budyko shifts indicate rising atmospheric evaporative demand and increasing energy limitation under future scenarios. ABSTRACT Assessing hydroclimatic variability and future water availability is crucial for sustainable water‐resource ...
