PASSO GAVIA, Italy - Scientists in Italy are investigating the mysterious appearance of pink glacial ice in the Alps, caused by algae that accelerate the effects of climate change.
There is debate about where the algae come from, but Biagio Di Mauro of Italy's National Research Council said the pink snow observed on parts of the Presena glacier is likely caused by the same plant found in Greenland.
The plant, known as Ancylonema nordenskioeldii, is present in Greenland's so-called Dark Zone, where the ice is also melting. More algae appear as the ice melts more rapidly, giving them vital water and air and adding red hues to the white ice at the Passo Gavia, altitude 2,618 meters . "We are trying to quantify the effect of other phenomena besides the human one on the overheating of the Earth," said Di Mauro, noting that the presence of hikers and ski lifts could also have an impact on the algae."Overheating of the planet is a problem, the last thing we needed was algae," said tourist Marta Durante.
