Photos: Pink ice cream in Italian Alps raises concerns over climate crisis

An aerial photo taken over the Presena Glacier near Pellizzano shows pink-colored snow on July 3. Italian scientists are studying this mysterious phenomenon which is linked to the algae which is believed to accelerate the effects of climate change. (Miguel Medina / AFP)

A man is seen walking on the pink colored glacial ice on 04 July. The origin of the algae is debated; However, Biagio Di Mauro of the Italian National Research Council believes that the pink snow seen on parts of the Presena Glacier is probably caused by the plant Ancylonema nordenskioeldii, also found in the “ dark zone ” of Greenland where the ice is melting rapidly. .

Di Mauro, who had previously studied algae from the Morteratsch Glacier in Switzerland, told AFP that “the algae is not dangerous, it is a natural phenomenon that occurs during periods of spring and summer. been at mid-latitudes but also at the poles. (Miguel Medina / AFP)

A CNR (National Research Council) researcher takes samples of pink snow. Normally, ice reflects over 80% of solar radiation back into the atmosphere, but as algae appears, it darkens the ice so that it absorbs heat and melts faster. Melting ice gives them vital water and air while adding red hues to white ice. (Miguel Medina / AFP)

Giving AFP a final overview of his research, Di Mauro said: “We are trying to quantify the effect of other phenomena besides humans on the overheating of the Earth,” noting that the presence of hikers and lifts could also have an impact on algae. (Miguel Medina / AFP)
