Scientists in Italy are investigating the mysterious appearance of pink ice in the Alps. The initial cause was determined by algae affected by the effects of climate change.
The issue of concern to scientists is where the algae come from. According to researcher Biagio Di Mauro of the Italian National Research Council, the pink ice observed on parts of the Presena glacier is likely due to the same algae found in Greenland.
"Algae are not dangerous, it's a natural phenomenon that occurs during spring and summer at medium latitudes," said Di Mauro, who previously studied algae at Morteratsch glacier in Switzerland. know.
Normally, ice reflects more than 80% of the Sun's radiation into the atmosphere, but when algae appear, they darken the ice to absorb heat and melt faster.
