Snow in the Arctic turned Pink!

The Arctic snow is melting. What's new, you might ask? Dangerous as it is (both the phenomenon and the question), the melting Arctic has got a new reason to have us all very worried.

Climate change has turned the Arctic snow pink. No, it's not a pretty pink. It's as dangerous as it can get. Rose snow, as it's known, is not so uncommon in high altitudes and occurs when the green algae turns pink after absorbing too much ultraviolet rays.

As scary as this is, the rose snow also directly leads to the melting of the glacier belt.

By examining the albedo of rose snow, scientists can figure out how much light is not absorbed by the algae. The rose snow revealed that the red algae decreased albedo by 13 per cent.

"Our results point out that the ‘bio-albedo’ effect is important and has to be considered in future climate models," said Stefanie Lutz, an author of a study said in a statement.
