Italian scientists investigate pink glacial ice in the Alps

An Italian glacier is turning pink. And that's not good news

Do they really pose threats to the planet?

It is not risky, he said, adding that it was a natural phenomenon that happens during the spring and summer in mid-latitudes and also at the Poles. The report mentions that normally ice reflects more than 80 percent of the sun's radiation.

The plant, known as Ancylonema nordenskioeldii, is present in Greenland's so-called Dark Zone, where the ice is also melting.

"The algae aren't unsafe", Di Mauro said.

More of these organisms will appear when the ice melts more quickly, providing air and water, as well as adding the color to the white-coated alps at Passo Gavia.


Algae at quite low temperatures will generally die, but when the ice becomes very marginally warmer it may cause a thin coating of water which enables it to survive and spread, thus accelerating the melt. The location is at 2,618 meters or around 8,590 feet from the ground. These massive bodies of ice shift and flow under their own weight, but many glaciers are now shrinking. Durante added, "Unfortunately we are doing irreversible damage".

Another tourist, Elisa Pongini from Florence, said that Earth was giving back what humans did to the planet.

Numerous glaciers in the Alps are already under threat due to climate change, with experts predicting glaciers will vanish from half of UN-designated World Heritage sites this century unless greenhouse gas emissions are curbed.

Ms Elisa Pongini from Florence said she felt the Earth was "giving us back everything we have done to it", adding: "2020 is a special year: bad things have happened". She said this year was a special one as "terrible things" have happened, claiming atmospheric phenomena are worsening and that climate change is "increasingly evident".

In his opinion, on the distribution of algae to the South could affect climate change. In the northern hemisphere for instance, summer has begun but in Alaska and Canada, this worldwide phenomenon has seemed to have affected thousands of the region's stream fish from their habitats. Meanwhile, others have journeyed distances including rivers, lakes, and smaller habitats upstream.
