The presence of snow in the Alps could be a bad sign.

Pink snow has emerged in the Italian Alps, providing clues about the impact of humans on the Earth’s climate,media BGR reported. The color of the snow changes because algae multiply, absorbing more heat and then melting more snow. These algae multiply as the climate warms and the sun shines on it.

The presence of snow in the Alps could be a bad sign.

As Earther reports, the algae, known as Chlamydomonas nivalis, is common in many of the coldest parts of the earth, including Antarctica and Greenland, and is a more serious problem than it looks. Bright white snow reflects sunlight back into space and absorbs less heat than dirt or rocks. As human activities gradually warm the planet, more and more snow in the Alps and other places are melting, but there is not enough new snow to make up for it. Glaciers are dying out, and pink snow is covered in tiny algae, not as white as the new snow, which means it absorbs more and more heat.

The more heat the noise absorbs from the noise, the more it melts. The more snow melts, the higher the temperature, the more algae there are. This is a vicious circle that inevitably leads to a large loss of ice and snow.

“Less precipitation in winter and higher temperatures in spring and summer are expected to contribute to the formation of snow and glacial algae,” said Biagio Di Mauro, a researcher at the Polar Science Institute of the Italian National Research Council. “
