<p>Climate change is resulting in mass loss and the retreat of glaciers in the Andes, exposing steep valley sides, over-deepened valley bottoms, and creating glacial lakes behind moraine dams. Glacial Lake Outburst Floods (GLOFs) present the biggest risk posed by glacier recession in Peru. Understanding the characteristics of lakes that have failed in the past will provide an aid to identifying those lakes that might fail in the future and narrow down which lakes are of greatest interest for reducing the risks to local vulnerable populations. </p><p>Using a newly created lake inventory for the Peruvian Andes (Wood et al., in review) and a comprehensive GLOF inventory (unpublished) we investigate lakes from which GLOFs have occurred in the past. This is to establish which physical components of the glacial lake systems are common to those lakes that have failed previously and which can be identified remotely, easily and objectively, in order to improve existing methods of hazard assessment.</p>

Political Scene

Social conflicts in Argentina over the past decade have retrieved the essence of the capitalist dispute: the struggle between capital and labor as situated in the workplace and no longer across urban space as it was in the 1990s. In this context, both institutionalized and alternative union expressions regained their centrality for analyzing social reality. The revitalization of collective bargaining and the consequent repositioning of unions on the labor and political scene activated grassroots dynamics that sometimes challenged existing union structures. Few experiences of resistance were able to alter the balance of power as much as the workers’ organization of the Buenos Aires subway. This organization was able to achieve such gains because of a combination of the strategic importance of the subway to the city’s production and reproduction, the fact that the privatization of the firm was a time-limited concession rather than a direct sale, the union tradition and workers’ awareness of lost rights, and the incorporation of new workers with a history of political militancy. Los conflictos sociales en Argentina durante la última década han recuperado la esencia de la disputa capitalista: la lucha entre el capital y los trabajadores como situado en el lugar de trabajo y ya no a través del espacio urbano, como lo fue en la década de 1990. En este contexto, las dos expresiones sindicales institucionalizadas y alternativas recuperaron su centralidad para el análisis de la realidad social. La revitalización de la negociación colectiva y la consecuente reposición de los sindicatos sobre el escenario laboral y político activan dinámicas de base que a veces desafiaban las estructuras sindicales existentes. Pocas experiencias de resistencia fueron capaces de cambiar al equilibrio de poder tanto como la organización de trabajadores del metro de Buenos Aires. Esta organización fue capaz de lograr tales ganancias debido a una combinación de la importancia estratégica del metro para la producción y reproducción de la ciudad, el hecho de que la privatización de la empresa fue una concesión de tiempo limitado más bien que una venta directa, la tradición sindical y la conciencia de los trabajadores de los derechos perdidos, y la incorporación de nuevos trabajadores con antecedentes de militancia política.

Outburst Floods

<p>Despite being a rather rare phenomenon when compared to the occurrence rates of other alpine hazards (e.g. landslides, avalanches), glacial lake outburst floods (GLOFs) pose a significant threat to downvalley communities in glaciated mountain areas. Characteristically high peak discharge rates and flood volumes, documented to have reached 30,000 m³/s and > 50 million m³ in the past century, not only provide GLOFs with a landscape-forming potential but also killed a reported global total of > 12,000 people and caused severe damage to infrastructures. Extensive glacial covers and steep topographic gradients, coupled with rapidly changing socio-economical implications, make the Hindu-Kush-Himalaya (HKH) a high priority region for GLOF research, even though recent studies suggest an annual occurrence rate of 1.3 GLOFs per year across this range during the past three decades. So far, GLOF research in the greater HKH region has been predominantly focused on the classification of potentially dangerous glacial lakes derived from analysing a limited number of glacial lakes and even fewer reportedly GLOF-generating glacial lakes. Moreover, subjectively set thresholds are commonly used to produce GLOF hazard classification matrices. Contrastingly, our study is aimed at an unbiased, statistical robust and reproducible assessment of GLOF susceptibility. It is based on the currently most complete inventory of GLOFs in the HKH since the 1980’s, which comprises 38 events. In order to identify key predictors for GLOF susceptibility, a total of 104 potential predictors are tested in logistic regression models. These parameters cover four predictor categories, which describe each glacial lake’s a) topography, b) catchment glaciers, c) geology and seismicity in its surroundings, and c) local climatic variables. Both classical binary logistic regression as well as hierarchical logistic regression approaches are implemented in order to assess which factors drive susceptibility of HKH glacial lakes to sudden outbursts and whether these are regionally distinct.</p>

American Cities

The Parisian Faubourg Saint Germain and perhaps the Rue de la Paix and the boulevards seemed the adequate measure of luxury to all of the snobs. The old colonial shell of the Latin American cities little approximated such scenery. The example of Baron de Haussmann and his destructive example strengthened the decision of the new bourgeoisies who wished to erase the past, and some cities began to transform their physiognomy: a sumptuous avenue, a park, a carriage promenade, a luxurious theater, modern architecture revealed that decision even when they were not always able to banish the ghost of the old city. But the bourgeoisies could nourish their illusions by facing one another in the sophisticated atmosphere of an exclusive club or a deluxe restaurant. There they anticipated the steps that would transmute “the great village” into a modern metropolis.—José Luis Romero

The Imlay channel in Lapeer County, Michigan was one of two outlets for the glacial Lake Maumee phase of ancestral Lake Erie. Fifteen new radiocarbon and optical ages from within and adjacent to the Imlay channel constrain sedimentation rates within the channel and the timing of regional deglaciation. For nearly 50 years the deglaciation of this region of Michigan has been based on a single age from the Weaver Drain site located near the Imlay channel, and a new radiocarbon age of 16.7–17.0 cal ka BP from 3 km east of the Imlay channel supports this long-standing deglacial age. On average there is a 14 m thick sediment fill within the channel. Radiocarbon and OSL ages reveal that much of the alluvial fill was deposited by 14.9 ka, and alluvial fans building into the channel stabilized in the early Holocene. Cross-sections along and perpendicular to the Imlay channel, built from geotechnical borings and water-well records, reveal a current-day bedrock sill elevation at 235 masl that would have permitted drainage of all stages of glacial Lake Maumee in the past.
