Blood Snow or red snow: we tell you why it happens

blood snow

Have you ever seen bloody snow on social media or in any television documentary? Are you scared Did you find it curious? This phenomenon is called 'Blood Snow' and we are going to tell you why and how this strange phenomenon is technically called.

Everything that we are going to tell you in this article is collected from different studies and blog posts which explain the phenomenon. But we already anticipate that more than natural, it can be something provoked. And you may be wondering, why? Well, in principle, according to studies it seems that it is due to climate change. One more indicator of what is happening on our planet.

Blood Snow What is it really?

To answer this, as we have told you before, we have had to investigate in different portals and foreign studies. But we have found answers and we can tell you what Blood Snow is.

red snow

Technically we can call this phenomenon as Chlamydomonas nivalis, and it is based on the fact that different species of green algae, which contain different pigmentation inside them, including red, undergo a photosynthesis process and subsequently stain the snow. Therefore, that's it, it is not blood in the middle of the snow, it is not because any animal or person has bled on it or anything like that. Simply, in quotes, it is an algae.

It is true that no one has suffered on top of the snow, and that we should not be scared by it, but the reality is that yes it is an indicator that something bad is happening on our planet and its nature and that we should be scared by other kinds of things that we are causing.

All these photographs that we find of snow with red color come from areas such as the Alps, Greenland or Antarctica itself. What then happens in these areas for this phenomenon to occur? that we are warming the planet above what we should. These regions are heated above normal and to your misfortune. This causes a thaw and that same thaw is what seems to cause perfect conditions to appear for this type of pigmented algae to flourish.

First known appearances of Blood Snow

HR first occurrences of this phenomenon date back to Aristotle, yes, as you have read it, in his writings. This phenomenon has been going on for hundreds or thousands of years in which during all of them it has kept different climbers, mountaineers, naturalists and other people who pass through such cold places that little by little they are warming up.

Over the years since the third century BC, it has been receiving different names, such as watermelon snow. See if this 'natural' phenomenon has time that he himself The Times already wrote about him on December 4, 1818.

The recent discovery is due to a captain who noticed the strange redness of the ice that came out of his path. This ice was subjected to different studies and analyzes because they did not give credit and no one believed that at some point red snow or blood snow had fallen.

What was discovered in these different studies carried out at that time is that during the winter months the Chlamydomonas nivalis, commonly known as Blood Snow, it becomes totally inactive. It is in spring with the increase of heat and of the light itself when it begins to bloom thanks to the nutrients it finds in the environment, which stimulate the algae to be able to expand with the thaw.

In the end, what causes this phenomenon is that the thaw accelerates and the area is gradually losing its landscape, something that in such cold areas and with so much frozen water does not suit us at all.

Why does it thaw before? because the red color of pigmented algae reflects less light from the sun and therefore a much faster thaw is caused, unfortunately for the planet. In the end it is nothing more than the whiting that bites its tail and that in any case, is harmful to our planet since we do not want the thaw to increase and with it the sea level.

Other curious phenomena: Blue Tears

blue tears

Our planet is full of this type of phenomenon, in many cases (almost all) caused by the existence of human beings and accelerated climate change that we also provoke ourselves on a daily basis with our disregard for the environment and its well-being.

For example, the so-called Blue Tears appear in the seas of Taiwan. These blue tears, according to different reports collected in the Matsu Islands area, what they cause is a great blue glow in summer. Once again it is due to the appearance of different flora, that is, different living creatures that in this case are bioluminescent and which are called dinoflagellates. All this attracts high numbers of tourists, who we assure you do not know that that blue glow is anything but good, since it is very toxic and every year it is increasing in these areas of Taiwan.
