Ancient runestone can shed light onclimate changes that occurred long before the climatic events of the 21st century. Such an unexpected conclusion was reached by specialists studying the cold climate crisis of Scandinavia in the VI century AD. The stone, which was raised in the ninth century near Lake Vatter in the south of central Sweden, is the bearer of the longest runic inscription in the world with more than 700 runes covering all 5 sides of the unusual find.
Have climate changes occurred in the past?
The problem of modern climate changeis one of the main problems of our century. However, according to an article published on sciencealert.com, similar events could have happened before. A proof of this can be found stone, which was erected as a monument to the deceased son of one of the rulers of the Ostrogoths, who lived on the territory of modern Italy. Researchers believe that the events on the stone describe a period of extremely extreme winter, which, according to the author of the runestone, was similar to the winter of 536 A.D.

It is believed that the crisis of the sixth century was caused bya chain of volcanic eruptions, which greatly influenced the climate, causing the appearance of lower average temperatures, lower yields, hunger and mass extinctions of livestock. As a result of the above events, the population of the Scandinavian peninsula decreased by at least 50 percent, and the memory of what happened began to be inherited, influencing the mythology of the northern peoples.
Bo Graslund, professor of archeology at the UniversityUppsala, believes that in addition to cold winters and bloody wars, the runic drawing describes a powerful solar storm, an extremely cold summer and even a solar eclipse, as a result of which the sky turned into dramatic shades of red.
Be that as it may, for global coolingThe early Middle Ages came global warming. According to studies, the peak of warming in this period occurred in the 11th-10th centuries CE, when grapes and other heat-loving crops began to grow in Iceland, on the Baltic Sea, and even in England. In addition, Greenland discovered in the 10th century could get its name for a reason. Most likely, the largest island of the planet once really was almost completely covered with greenery. As evidence of this incredible fact, scientists cite the outbuildings and household items of the Vikings of that period that have survived to this day. In this case, perhaps climate change is not related to human activity and is cyclical in nature? Let's try to discuss this issue together in our official Telegram chat.
