Africa-Press – Tchad. <\/strong><\/span>La disparition presque compl\u00e8te d\u2019une p\u00e9ninsule glaciaire a \u00e9t\u00e9 constat\u00e9e par les scientifiques du parc national de l’Arctique russe. Ils ont pr\u00e9cis\u00e9 que cette perte de glace avait eu lieu dans l’archipel Fran\u00e7ois-Joseph, en ajoutant qu\u2019il est possible qu\u2019il y ait d\u2019autres changements des contours g\u00e9ographiques dans la r\u00e9gion.<\/p>\n

Alors que le changement climatique et sa dangerosit\u00e9 pour l\u2019avenir de l\u2019humanit\u00e9, ainsi que les moyens de le ralentir, sont derni\u00e8rement au c\u0153ur des discussions \u00e0 tous les niveaux, y compris lors de la COP26, le personnel du parc national de l’Arctique russe a enregistr\u00e9 la disparition d\u2019une p\u00e9ninsule, indique le site du parc. Ce parc russe fond\u00e9 en 2009 couvre une surface d\u00e9sertique de l’Arctique, la partie septentrionale de la Nouvelle-Zemble et la terre Fran\u00e7ois-Joseph.<\/p>\n

Lors d’un raid autour de l’\u00eele Eva-Liv, dans l’archipel Fran\u00e7ois-Joseph, le personnel du parc a constat\u00e9 que la p\u00e9ninsule qui se termine au cap Mesyatsev avait presque enti\u00e8rement fondu. Les scientifiques ont inspect\u00e9 la zone autour de l’\u00eele Eva-Liv et ont d\u00e9couvert qu’un d\u00e9troit de trois kilom\u00e8tres de large s’\u00e9tait form\u00e9 au milieu du cap Mesyatsev.<\/p>\n

Il a not\u00e9 que la carte de l’\u00eele avait \u00e9t\u00e9 r\u00e9alis\u00e9e il y a plus d\u2019un demi-si\u00e8cle et qu’elle \u00e9tait d\u00e9sormais d\u00e9pass\u00e9e. Il \u00e9tait estim\u00e9 qu\u2019ils fallait plus d\u2019un an au glacier pour fondre. Les premiers rapports indiquant que la p\u00e9ninsule avec le cap Mesyatsev s’\u00e9tait s\u00e9par\u00e9e de l’\u00eele Eva-Liv avaient d\u00e9j\u00e0 \u00e9t\u00e9 faits en 2017.<\/p>\n

En raison du changement climatique, les contours des glaciers de la terre Fran\u00e7ois-Joseph changent rapidement. En 1894, Fridtjof Nansen, explorateur polaire, en la d\u00e9couvrant, pensait avoir trouv\u00e9 deux \u00eeles. Il l’a m\u00eame baptis\u00e9e de deux noms: le plus grand Eva, en hommage \u00e0 sa femme, et le plus petit Liv, en hommage \u00e0 sa fille.<\/p>\n

Selon les experts, il existe encore de nombreux endroits sur l’archipel o\u00f9 les scientifiques pourraient enregistrer des pertes de glaciers et des changements des contours g\u00e9ographiques. Ce n’est pas la premi\u00e8re fois que les scientifiques signalent des pertes suite \u00e0 la fonte des glaces et des glaciers dans le monde.<\/p>\n

En 2020, les scientifiques de ce m\u00eame Centre ont termin\u00e9 une exp\u00e9dition sur les glaciers de l’Oural polaire, au cours de laquelle ils ont d\u00e9couvert que l’un des plus grands glaciers de la r\u00e9gion avait fondu. Au milieu du XXe si\u00e8cle, ce glacier \u00e9tait le deuxi\u00e8me plus grand et le plus long de l’Oural. Lors de sa d\u00e9couverte en 1953, sa longueur atteignait 2,2 kilom\u00e8tres.<\/p>\n

En outre, en 2021, les scientifiques ont d\u00e9couvert qu\u2019un glacier de six m\u00e8tres de haut dans une grotte en Sib\u00e9rie occidentale en Russie avait pratiquement fondu en neuf ans. Alors qu’en 2012 le glacier avait une superficie de 50 m\u00e8tres carr\u00e9s, il ne d\u00e9passe pas aujourd’hui 50 centim\u00e8tres.<\/p>\n
