Le glacier Perito Moreno se trouve en Argentine (Patagonie). À la différence d’autres glaciers caractérisés par les effondrements de pans de glace, le Perito Moreno détache d’immenses blocs de glace. À n’importe quelle époque de l’année, se produisent des effondrements constants de ses murs de glace. Le front du glacier avance sur le lac Argentino face à la péninsule de Magellan. Quand il atteint la rive opposée, il divise le lac en deux créant des digues naturelles. Les eaux du bras Rico du lac Argentino montent alors (jusqu’à trente mètres) et commencent à éroder le glacier qui devient moins résistant et cède sous la pression. Cet effondrement spectaculaire du front du glacier a lieu périodiquement, mais la fréquence de ce cycle est irrégulière et peut prendre d’un an à une décennie. La première rupture a été observée en 1917. La dernière date du 10 mars 2016, et la voici:

Le parc national Los Glaciares est une aire protégée de 539 300 ha qui se situe dans le sud-ouest de la Patagonie argentine, à la frontière chilienne. Ce parc englobe deux grands lacs d’origine glaciaire et quelques lacs plus réduits, ainsi que quelques montagnes mythiques, comme le Fitz Roy (ou Chaltén), de 3 405 m, et le Cerro Torre, de 3 102 m.

Le photographe de Getty Images Mario Tama s’y est rendu récemment, et a pris ces photographies (vous pouvez en voir plus ici). Un monde en danger face au réchauffement climatique…

The majority of the almost fifty large glaciers in the park have been retreating over the past fifty years due to warming temperatures, according to the European Space Agency (ESA). The United States Geological Survey reports that over 68 percent of the world's freshwater supplies are locked in icecaps and glaciers.

Le photographe Marco Vernaschi a réalisé une série de clichés sur les différentes identités qui composent l’Argentine.

01-suri-quecha-nandu-regalia-670Belén Cruz fait partie des Samilantes, un groupe au sein de la communauté Quechua. Son costume de plumes représente le nandou, l’oiseau sacré des Suris.

02-jasy-pora-guarani-670Hugo Martínez pose avec son coati. La communauté Guarani Jasy Pora vit près de la frontière brésilienne. Leurs noms espagnols reflètent le passé colonial du pays.

03-jujuy-quecha-diablos-670Dario González et son fils appartiennent au groupe « Los Diablos », au sein des Quechuas. Les Diablos croient que le diable peut à la fois maudire et protéger.

04-mapuche-hunters-670La plupart des membres de la communauté Mapuche sont des chasseurs, comme Salvador Quintriqueo (assis) est son fils, Ricardo.

06-mapuche-home-670Les demeures des Mapuche homes, comme celle de Marita Andreau (debout, avec son amie Rosa Andreau), ne possèdent ni électricité ni eau courante.

L’ancien village englouti d’Epecuén est à nouveau à sec

Villa Epecuén est un village argentin qui fut autrefois florissant. Situé à six heures de route au sud-ouest de Buenos Aires, il a été créé dans les années 1920 sur les rives du lac salé Epecuén. Les vacanciers arrivaient au village par train, et s’y détendaient dans les eaux du lac, que l’on croyait bonnes pour la santé.

Au plus haut, le village accueillit près de 5000 personnes, 280 commerces en tout genre. Puis vinrent les pluies, causées par les changements climatiques. À partir de 1980, des pluies torrentielles s’abattirent sur la région, sur une période de cinq années. Le 10 novembre 1985, le barrage cédait, et lentement mais sûrement, tout fut englouti. Pendant près de 25 ans, le village fut immergé sous 10 mètres d’eau.

Puis, le climat changea de nouveau. En 2009, la sécheresse qui sévissait en Argentine fit s’évaporer l’eau. Et Villa Epecuén ressurgit, sous une version plus blanche, plus rouillée et plus rongée d’elle-même.

Epecuen5 Epecuen4 Epecuen3 Epecuen2 Epecuen1Un seul habitant est revenu vivre au village. Pablo Novak, 84 ans, qui a passé sa jeunesse à Villa Epecuén, avec ses parents et onze frères et sœurs. Aujourd’hui, il passe ses journées à se détendre, à parcourir ce qu’il reste de rues sur son vélo rouillé. En 2013, voici comment il présentait sa vie:
