The Rök, one of the worlds' most famous pieces of rune stones is now believed to be carrying a note from the past. It is now believed to be erected by the ancient Vikings around 800 CE with 700 runes. It is the carrier of the longest runic inscription in the world.

Sweden’s crown jewel has always generated debate for over a century. However, for long, Scholars believed that it was built by an anxious Viking named Varinn to cope with the demise of his son Vāmōðʀ. However, the meaning of the text still remains elusive. The reason is few parts are missing, and they have different writing forms as well.

Have climate changes occurred in the past?

Climate change is real and it is something we all should be scared of. However, does this extremely ominous disaster happened before? Well, the answer might be lying on the Rök.

Previously it was believed that the stone was about "Theodoric". A great king and ruler of the Ostrogoths (Italy). But a researcher from three Swedish universities now believes that we might be missing something big here. According to the inscriptions, it is more of a reference to a severe winter. Which, according to the author of the rune stone, was similar to the winter of 536 A.D.

The crisis of the sixth century is believed to have been caused by a series of volcanic eruptions which dramatically changed the climate and lowered the temperature below average. This, in turn, destroyed the crops, livestock and created famine and later mass extinctions. It is believed that the population of the Scandinavian peninsula decreased by at least 50 percent and according to researchers this event later passed down through mythology.

Bo Graslund, a professor of archaeology at Uppsala University, believes that there's more to than just cold winter & wars in the Rök. According to him, several other significant events can be found in the text. Such as, the inscriptions talk about a powerful solar storm, a summer without any warmth and even a solar eclipse, for which, the sky turned into a bloody red shade.

Be that as it may, behind the long winter in the middle ages, there was global warming. According to the researchers, climate change began to happen in the 11th-10th centuries CE, when heat-loving crops were happily growing in Iceland and Baltic cost lines. One extraordinary thing to consider here is the name "Greenland". Most likely during the naming period in the 10th century on the largest island on the planet, the place was a lot greener than what we see today. So now we can see from where the name derived from!

Now researchers are examining the remains of this period to understand the ominous disaster. In this case, maybe it wasn't the fault of climate change. So, does this mean the long winter is a cyclic and natural event? If yes, then when and where it's going to hit us next?
