Algae Ancylonema nordenskioeldii can become “the last nail in the coffin” one of the Italian glaciers, scientists say.
In the Italian Alps found the pink ice. According to scientists, the glacier of the Presena turned this color because of the algae Ancylonema nordenskioeldii. On Monday, July 6, reported The Guardian.
According to scientists, the phenomenon may have negative environmental impacts, because the algae speed up the melting of the ice.
Now there are disputes about where it came from seaweed, painting the glaciers in the Alps in pink. According to Biagio Di Mauro of the National research Council of Italy, pink ice, probably caused by the same plant that painted the glaciers of Greenland.
“The mere existence and proliferation of these organisms in glaciers is quite natural, especially in the summer season. However, the intense staining of ice algae poses a threat to the permafrost,” said the scientist.
The plant, known as Ancylonema nordenskioeldii, present in the so-called dark zone of Greenland, where the ice is melting. Typically, the ice reflects more than 80 percent of the sun’s radiation back into the atmosphere, but when algae start growing, they darken the ice, so it absorbs heat and melts faster. As soon as the ice melts faster, there are more algae.
According to Di Mauro, who previously studied algae on the glacier Mortars in Switzerland, the presence of tourists and the lifts can also influence algae.
Scientists emphasize, that the algae speed up the melting of ice in the Alps, which contributes to global climate change.
