A type of algae that accelerates the effects of climate change has caused glaciers in Italy to turn pink.

Scientists are investigating after pink ice appeared on parts of the Presena glacier in the Italian Alps.

Biagio di Mauro, a scientist at Italy’s National Research Council, said the colour is caused by a plant, which is more commonly 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,” he told the Guardian.
