Italian scientists 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 alga is not dangerous, it is a natural phenomenon that occurs during the spring and summer periods in the middle latitudes but also at the Poles,” said Di Mauro.
