Roundup: Venezuela, Peru, and the Storglaciären

The Death of a Venezuela Glacier

The Economist: “Venezuela is a tropical country, with rainforest in the south and east, and baking savannah stretching towards its northern Caribbean coast. The Sierra Nevada de Mérida mountain range in the north-west offers relief from the heat. In 1991 five glaciers occupied nooks near their peaks. Now, just one remains, lodged into a cwm west of Pico Humboldt. Reduced to an area of ten football pitches, a tenth of its size 30 years ago, it will be gone within a decade or two. Venezuela will then be the first country in the satellite age to have lost all its glaciers.”

Small-Scale Farmers’ Vulnerability in the Peruvian Andes

From Iberoamericana: “Previous studies have shown that climatic changes in the Peruvian Andes pose a threat to lowland communities, mainly through changes in hydrology. This study uses a case study approach and a mixed qualitative-quantitative method to examine the vulnerability of small-scale farmers in the Quillcay River basin to variations in precipitation and enhanced glacier retreat. The findings of the study show partly contradicting results. On one hand, interpretation of semi-structured interviews suggests a strong relation between climate proxies and increased vulnerability of the smallholders. On the other hand, in the quantitative analysis enhanced glacier retreat seemed to have augmented vulnerability solely to some extent whereas precipitation did not show significant impact.”

A Glacier-Permafrost Relationship in Sweden

From Quaternary Research: “Here, we present empirical ground penetrating radar (GPR) and electroresistivity tomography data (ERT) to verify the cold-temperate transition surface-permafrost base (CTS-PB) axis theoretical model. The data were collected from Storglaciären, in Tarfala, Northern Sweden, and its forefield. The GPR results show a material relation between the glacial ice and the sediments incorporated in the glacier, and a geophysical relation between the ‘cold ice’ and the ‘temperate ice’ layers…The results show how these surfaces form a specific continuous environmental axis; thus, both glacial and periglacial areas can be treated uniformly as a specific continuum in the geophysical sense.”

Photo Friday: Crowd-Sourced Images of Glacier Retreat

Imagine if we had a crowd-sourced digital record of the damage climate change is causing to our planet. That’s the mission of Project Pressure, an UK-based organization dedicated to documenting and publicizing the world’s vanishing glaciers. With MELT, an open source digital atlas, Project Pressure hopes to give the public a new tool to visually tour the world’s receding glaciers, helping us all to better understand the ongoing impact of rising global temperatures.

Rather than relying on satellite images and direct measurement, two techniques that have their limits, Project Pressure hopes to document glacier fluctuations of the world’s 300,000 glaciers through comparative imagery. This will allow researchers to analyze glaciers otherwise inaccessible for direct measurement and provide new visual insights to changes in glacier length.  The images are both heartbreaking and alarming, demonstrating both the staggering beauty of our world glaciers and their current state of decline.

Take a look at GlacierHub’s collection of images from Project Pressure, and learn more about the initiative here.
