At Least Two International locations Have Misplaced All Their Glaciers
Two international locations—Slovenia and Venezuela—have misplaced all of their glaciers. It’s a grim benchmark displaying the development of local weather change
CLIMATEWIRE | Slovenia and Venezuela are the primary two international locations to lose their last-standing glaciers in a interval of local weather change induced by individuals — however they gained’t be the final.
Some information shops reported this month that Venezuela could be the primary nation in trendy occasions to lose all of its glaciers. Nevertheless, researchers informed E&E Information that Slovenia probably claimed the solemn title greater than three many years in the past.
“The two glacial remnants have not moved, [and] there were no glacial crevasses observed in the last few decades — these characteristics define real glaciers,” Miha Pavšek, who leads ice measurements at Slovenia’s Triglav mountain and Skuta peak with the Anton Melik Geographical Institute, informed E&E Information.

Melting glaciers are one of many iconic penalties of human-caused local weather change, and even Arctic international locations like Iceland have misplaced complete glaciers. However Slovenia and Venezuela look like the primary international locations because the 18th century to lose their final glaciers. It comes because the Intergovernmental Panel on Local weather Change expects 18 to 36 p.c of world glacial mass to be misplaced throughout the twenty first century due largely to world warming.
A Might put up on X, previously Twitter, by climatologist Maximiliano Herrera drew consideration to the decline of La Corona — Venezuela’s final glacier — by citing December measurements from the Universidad de Los Andes displaying a remaining space of 0.02 sq. kilometers.
“The disappearance of all the glaciers in Venezuela is a national tragedy,” Julio César Centeno, a professor at Universidad de Los Andes who studied the glaciers, informed E&E Information in an e-mail. “It is a warning sign about the avalanche of additional effects that are coming to the country in the short term as a consequence of global warming.”
However Slovenia and Venezuela probably misplaced their final glaciers years earlier.
There’s no universally accepted level of demise for a glacier, and no worldwide group is acknowledged because the authority on glacial classification. However Centeno mentioned that “the minimum size for a glacier is 0.1 [square kilometers.]” The US Geological Survey additionally makes use of that threshold and says it’s “the commonly accepted guideline.”
In Slovenia, Skuta’s space has been beneath 0.1 sq. kilometers since no less than 1969, and Triglav fell beneath the edge in 1986. La Corona, in Venezuela, probably misplaced its glacial standing in 2016.
Pavšek and Centeno say that past the dimensions threshold, the remnant glaciers in Slovenia and Venezuela aren’t appearing like they used to.
“Two basic characteristics for the real glaciers are their moving and the presence of glacial crevasses,” Pavšek mentioned, including that Triglav and Skuta haven’t possessed both “in the last few decades.” The quantity of ice on the peak of Triglav is “the area of two volleyball courts,” whereas Skuta’s shaded place has afforded it double that floor space: 0.01 sq. kilometers.
The low altitude and latitude of each glaciers made them “more vulnerable to climatic extremes” they usually succumbed to “rising temperatures,” Pavšek mentioned. The Anton Melik Geographical Institute expects each summits to be ice-free by 2030.
Centeno mentioned that after additional melting in 2022, Venezuela’s La Corona is a shell of its former glacial standing. La Corona, he mentioned, is “an unburied corpse in an advanced state of decomposition.”
The lack of these glaciers and people to observe will carry heavy environmental penalties.
The Slovenian glaciers each soften into the Black Sea and La Corona empties into the Caribbean, contributing to rising world sea ranges which can be anticipated to wreak havoc on coastal communities.
“It is also a clear and resounding warning for the rest of Latin America,” Centeno mentioned. “The consequences of the inevitable loss of the glaciers of Colombia, Ecuador, Peru and Bolivia will have a social impact much greater than that of Venezuela, due to the dependence of much larger populations on water sources dependent on these glaciers.”
Mexico’s final glacier, Gran Norte, is anticipated to lose its standing someday between 2026 and 2033 and be utterly passed by 2045. Its runoff has offered downstream communities with water for hundreds of years.
La Corona was the final of the “Five White Eagles” — glaciers that capped the mountains above town of Mérida. Centeno sees its demise as a name to motion on local weather change: “What are we waiting for to act?”
“Mérida is no longer the City of Eternal Snows. The Five White Eagles have disappeared. We have destroyed them, annihilated them. They are among the first Venezuelan victims of global warming. Many others gather at the gates of extermination. Not only plants, animals, water sources and fertile soils, but humans, many humans,” Centeno mentioned.
