A sharp drop in temperatures could have played a leading role in the outcome of the Roman Empire. This was collected by a study carried out by scientists from the "Past Global Changes" project. His research was collected and published in the magazine Nature Geoscience. And not only in the ancient Roman civilization, but many more civilizations throughout history.
It is curious because, often the movies and a natural ignorance for not having lived the ancient past times, lead us to think that the reorganizations of ancient civilizations are due to many other factors. It is not usually realized that, the climate has a very direct influence on all living beings. In our case, we have not been an exception. Although there is often a tendency to forget the determining role that prevailing weather plays at each moment.
The causes and consequences of cooling
The period from which it is dated comprises between AD 536, and 660. The effects of this cooling could be felt in very wide areas, which caused political upheavals, social transformations and even the fall of empires from Europe to Asia, and even part of the Arab region. This long-lasting ice age was brought about by the large eruption of various volcanoes. The first of them in 536, the second in 540 and finally in 547.
Climate cooling produced by the volcanoes it is due to large ejections of small particles, sulfate aerosols. These enter the atmosphere blocking sunlight. The blocking process that prevents sunlight from entering through its refraction has been studied at present to provide a solution to global warming. On the part of Harvard University there is also a geoengineering project called Scopex targeting intentional cooldown using this technique.
Another of the effects that were experienced was the plague of the Justaniano pandemic that spread through the Mediterranean between 541 and 543. It reached Constantinople and was responsible for claiming the lives of millions of people even centuries later. What it teaches us, that the role of the climate, has been decisive in the evolution of our civilization even in relatively recent times.
