The period of 'ice age' is the cause of epidemics, the empires collapse and migrate

When it comes to climate change, most people will think about the rise in temperature, drought, and storms - the kind of climate change that the Earth is currently experiencing. So far there are many records of how drought and its effects have caused the empires and kingdoms to collapse.

Currently, a group of researchers is considering another type of climate change - a glacial period - which they say has caused a number of Eurasian empires, including the La empire. The code, faded or collapsed and may have pushed the mice to evacuate the disease to Eastern Europe.

The study authors, led by Professor Ulf Büntgen from the Swiss Federal Research Institute, wrote an article in Nature Geoscience, which says that climate change has caused "reorganizations." society " in Asia and Europe.

"In particular, the 6th century period coincides with the period of development and destruction of civilizations, types of epidemics, migration and political instability," a summary of 16 dongs. study author said.

Scientists working in this study include climatologists, geographers, historians, physicists, and a linguist. They observed the age of trees from the Altai Mountains in Russia and the Alps (Alps) in Europe to measure summer temperatures over the past 2,000 years.

They claim that the Little Ice Age was around 1450 until the late 1800s, not as serious as the catastrophe that hit the Eurasian continent in the 6th and 7th centuries.

Their summary has:

"We have found an unprecedented, long-term and synchronous cold condition followed by a series of massive volcanic eruptions in 536, 540 and 547 AD, perhaps sustained by Sea and ocean ice, as well as a period of minimum Sun. Therefore we determined the period from 536 to about 660 SCN as the Late Antiquity Little Ice Age. Pray, we believe that this glacial phase is an additional environmental factor that caused the Justinian Epidemic , the transition of the eastern Roman Empire and the collapse of the Sasanian Empire, the evacuated from the steppe in Asia and the Arabian Peninsula, the prevalence of Slavic speakers (Slavs) and the ripening events h treat in China ".

"Based on this research, we think this period is the coldest in the last 2,000 years ," Dr. Büntgen told New Scientist.

The cooler summers up to 4 degrees Celsius appear as a result of volcanic ash particles obscuring the Sun's light approaching the Earth. The average temperature difference is probably about 2 degrees C lower than the standard reference temperatures between 1961 and 1990.

An impact of changing weather patterns and temperature patterns is the remaining part of the Roman Empire, after being confined to the Mediterranean region, has lost even more power and more land. A shorter growing season of food crops may have reduced food production and caused famine. Hungry people are also more vulnerable. Another consequence is the potential occurrence of rodent species carrying diseases (such as rats, squirrels, .) in imperial territory.

However, some others have obviously benefited from the ice age. The Arabian Peninsula may have become less arid, thereby increasing the amount of crops and helping the camel herdsmen and perhaps, prompting Arabs to migrate to Europe, occupying the territory. Romans. New Scientist also reported that the Lombard (a German tribe) invaded Italy and took control from 568 to 774. And the Slavic languages ​​of the early period, which were unknown, has spread throughout the European continent during this period.

This historical period is known as the Late Antiquity . Büntgen and others named this period the Late Antiquity of the Ice Age.
